The document outlines the key stages of fetal development from conception through 36 weeks of pregnancy. It notes that after fertilization, the embryo forms three cell layers and a membrane begins to protect and nourish it. A placenta then forms to transfer waste and nutrients between the embryo and uterus. The development process lasts around three months, with the fetus increasing in size between weeks 12-23 and its heartbeat becoming detectable. Between week 24 and birth, the baby rapidly grows larger and its respiratory and circulatory systems undergo changes to prepare for breathing after birth.

Baby development
During the first trimester, the sperm and egg unite and begin to develop the placenta and basic organs and features by 8 weeks. In the second trimester, the baby's movements become more coordinated and detectable, and features like fingers, toes, and sex become apparent between 13-22 weeks. In the third trimester, the baby gains weight, bones harden, lungs mature, and positioning occurs for birth from 28 weeks until birth at 40 weeks.
Fetal development during pregnancy
1) The document describes the major stages of fetal development from conception through the full term pregnancy period.
2) It explains that at conception the fertilized egg attaches to the uterus and begins dividing rapidly, forming the basic structures of the body. By 6 weeks a heartbeat can be detected.
3) From weeks 11 to birth the fetus continues to develop and grow organs and tissues. Lungs are not fully mature until birth.
Human fetal development
Fetal development begins with fertilization and involves 3 key stages. First, the sperm fertilizes the egg and 3 germ layers form within 3 weeks. Next, the embryo develops further for 9 weeks. Then, membranes form to protect and nourish the embryo, including the amnion which holds fluid and the amniotic membrane. The fetus continues developing through 9 months, with rapid growth in the last trimester as organs and bones mature to prepare for birth.
Nancy
The document summarizes fetal development from weeks 1-8 of pregnancy. In week 1, pregnancy is counted from the first day of the last menstrual period. In week 2, fertilization occurs in the fallopian tubes as the egg and sperm join. In week 3, the fertilized egg begins rapidly dividing and implants in the uterus. In weeks 4-5, the blastocyst attaches to the uterus and divides into the placenta and embryo, with major organs beginning to form. In weeks 6-7, the heart begins beating and arms and legs start to grow. In week 8, the embryo practices moving as muscles develop and facial features become visible.
Fetal Development and the three stages of labor and delivery by Sandra Landin...
The document describes fetal development from conception through the third trimester of pregnancy. It details the key physical changes that occur each week, such as the formation of organs in the first few weeks, development of facial features at 7 weeks, and growth in length and ability to move at 8 weeks. Later stages see further physical maturation, such as the development of vocal chords at 12 weeks and the ability to hear at 20 weeks. The three stages of labor and delivery are also summarized as dilation of the cervix, expulsion of the baby, and delivery of the placenta.
Stages of foetal development
The document summarizes the stages of fetal development from fertilization to birth in 3 month periods. It notes that at fertilization, all the genetic information is present to determine characteristics. In the first 2 months, growth is very rapid but slows to prevent excessive birth weight. It outlines key developmental milestones that occur each month such as organ formation, skin and hair changes, movement and hearing. The document concludes with a table showing fetal size and weight by week of gestation.
Fetal Development
By the end of the first month, the embryo is about 1/10 of an inch long and the heart has begun beating. By two months, the embryo has distinct fingers and veins are visible, with the heart dividing into chambers. By three months, the fetus is fully formed at 2 1/2 to 3 inches long and organs and muscles have developed and are functioning.
Foetal development and growth in humans
Gestation typically lasts around 40 weeks or 280 days. It involves three main periods: the ovum stage from conception to implantation around 4-5 days; the embryonic stage from implantation to 8 weeks; and the fetal stage from 8 weeks until birth. During the first month, the placenta begins functioning and the embryo's heart starts beating while it is around the size of a raisin. By the second month, most major organs have formed but are not yet fully functional, and by the third month the brain is fully formed and the fetus can feel pain while continuing to develop hair, muscles, and the ability to taste. Birth normally occurs around 38-42 weeks when the baby weighs around 7 pounds and is 20 inches long

Fetal development
The document summarizes fetal development from conception through birth in 4 week intervals. At conception, a fertilized egg implants in the uterus and begins dividing rapidly. By 4 weeks, structures of the face and neck are forming and organs like the heart, lungs and liver begin developing. The fetus' size, features and movements continue developing through each stage until by 36 weeks it is nearly ready for birth, with most organs fully formed. Birth occurs around 40 weeks of pregnancy.
Conception to birth
Fertilization occurs when a sperm cell fuses with an egg cell, containing 23 chromosomes each to form a fertilized egg with 46 chromosomes. The average pregnancy lasts 38 weeks from conception. Within a few days, the fertilized egg begins cell division as it travels to the uterus where it implants by about 10 days after conception. The fetus continues to rapidly grow and develop organs over the next several weeks, with all major organs formed by 24 weeks.
Embrology Developmental stages of embryo
This document presents an overview of human embryology and fetal development from conception to birth in 3-sentence stages. It describes the key events from fertilization through cell division and implantation in the first few weeks. The major organ systems then develop throughout the subsequent weeks, with the fetus growing in length and weight. By week 35, the fetus is near its birth length and continues gaining fat in preparation for birth from week 36 to 40, when the fully developed fetus is ready to be delivered.
Living within the womb
The document describes the process of human reproduction and early fetal development from fertilization through the first few weeks of pregnancy. It explains that fertilization occurs when an egg and sperm join to form a zygote, which develops into a blastocyst and then implants in the uterus. The blastocyst becomes an embryo and a placenta begins to develop to nourish the growing fetus. During this period, defects can occur due to genetic factors or issues like alcohol or drug use. Physical development of the fetus accelerates in the third week as the hands, feet, fingers, toes, brain, lungs and eyelids form.
Embryo
An embryo is the early stage of development of a multicellular organism. It begins as a zygote formed from the union of an egg and sperm cell. The zygote divides through mitosis to become a ball of cells called a morula, then a hollow structure called a blastula. The blastula implants in the thickened uterine wall and develops a placenta and umbilical cord over 2 months to exchange gases and nutrients with the mother's blood. As it develops over 9 months, organs and limbs form and it grows in size until birth as a baby. Eating healthy during pregnancy is important for the developing lungs and brain of the embryo/fetus.
Foetal development gihs
The document discusses fetal development from 6 weeks to 38 weeks of pregnancy. It describes the key physical changes that occur in the embryo and fetus each week. During the first trimester (6-12 weeks), major organs begin to form and external features develop. In the second trimester (13-28 weeks), the fetus grows rapidly and all systems continue to mature. By the third trimester (29-38 weeks), the fetus prepares for birth by gaining weight and fat and increasing lung and brain development.
Fetal Development!
The document outlines the development of a baby from week 1 through month 9 of pregnancy. In week 1, embryo division begins and the embryo reaches the uterus by day 3. By week 2, the embryo secretes HCG and forms three layers and extraembryonic membranes. Between weeks 3-5, the nervous system appears and organs like the heart, eyes, ears, and limbs start developing. By weeks 6-8, the embryo is recognizably human, and between months 3-4 features like hair, nails, and sex can be determined. From months 5-7, the mother can feel movement and the fetus grows fine hair and protective vernix. In the final months, the fetus further refines its development
Human fetal development (saimphar, edna)
During the first trimester, the fertilized egg rapidly divides and implants in the uterus. All major organs form by the end of the first month. In the second trimester, the fetus grows fingers and toes, and sex organs form allowing for gender identification. Teeth and bones become denser in the fourth month. By the sixth month, the baby weighs about 2 pounds and is 12 inches long. In the third trimester, the baby gains weight and fat deposits. Hearing is fully developed by the seventh month. By the ninth month, the baby is ready for birth at around 7 pounds and 18 inches long.
Reproduction
There are two types of reproductive cells, the ovum and sperm, which contain genetic information from both parents. Conception occurs when the ovum and sperm join to form a zygote, which begins dividing and grows as it travels to the uterus. The zygote becomes an embryo that attaches to the uterus wall for protection and floats in amniotic fluid inside the amniotic sac for protection. A placenta then forms to provide oxygen and nutrients from the mother to the growing fetus via the umbilical cord until birth at the end of the ninth month of pregnancy.
The development of the fetus
The document outlines the development of a fetus over the three trimesters of pregnancy. In the first trimester, the fetus grows from the size of a fist to a grapefruit. During the second trimester, the fetus' ears form and the mother can feel movements between 18-22 weeks. In the third trimester, the fetus' bones are developed, its eyes are open, and it can control its body temperature.
Fetal development
During ovulation, which typically occurs 11-21 days after a woman's period ends, an egg is released from the ovaries. If sperm penetrate an egg in the fallopian tubes, conception occurs and the fertilized egg begins dividing as it travels down the fallopian tube. By 6-12 days after conception, the blastocyst implants in the uterine lining and the embryonic stage begins. Over the following weeks, all major organs develop as the embryo grows and differentiates into a fetus. By week 40, considered full term pregnancy, the fetus is ready for birth, weighing around 6.75-10 pounds.
Foetal development
Fertilization occurs when a sperm and egg join in the fallopian tube to form a unique human being. Within 30 hours this fertilized egg, called a zygote, begins rapidly dividing as it floats down the fallopian tube towards the uterus. By week 3-5 the embryo's heart begins beating and major organs start to form, while the placenta provides nourishment. By week 7 the embryo has its own blood type and visible features like hair follicles, and by weeks 8-12 it is known as a fetus and can move inside the amniotic sac. The brain is fully developed by weeks 13-16 and the fetus can feel pain and make movements.
Fetal Development
1. A single sperm fertilizes an egg to form a zygote, which divides and travels down the fallopian tube as a ball of cells called a blastocyst. The blastocyst implants in the uterine wall around 6 days after fertilization.
2. Around the second week, the cells begin to differentiate and form three layers that will become the embryo's tissues and organs.
3. By the third week, the neural plate forms and tiny blood vessels and heart structures start to develop.
Development of the_foetus (2)
Fertilization occurs when a sperm joins with an egg in the fallopian tube to form a zygote, which is no larger than the head of a pin. Over the following weeks, the embryo develops major organs and the ability to move as it floats down to the uterus. By week 8, the embryo has transitioned to a fetus, which continues growing and developing through the stages of pregnancy. By week 20, the fetus is covered in vernix, practicing breathing, and making active movements. In the final weeks of pregnancy, the fetus gains fat stores, sleeps most of the day, and has a high chance of survival if born.
17th-24th week of pregnancy
During weeks 17-24 of embryo development, the fetus' organs and body systems continue to develop and mature. The skeleton begins changing from cartilage to bone, sweat glands and eyes develop. Later weeks see the development of blood vessels, genitals, lungs, vocal cords, skin, hair, and digestive and nervous systems. By 24 weeks, the fetus is practicing breathing, responding to touch and sound from outside the womb, and most organs have reached their proper positions.
Fetal Development
The document summarizes fetal development from the first through third trimesters of pregnancy in 3-4 week increments. In the first trimester, the embryo grows rapidly, forms major organs, and develops a placenta and circulatory system. By 8 weeks, the baby's sex and organ systems are developing. In the second trimester, the fetus' skeleton, hair, ears, eyes, and other features form and mature. Fat begins to form in weeks 17-19. In the third trimester, the baby practices breathing, regulates its body temperature, and is fully capable of opening its eyes and detecting light by weeks 30-33.
Fetus
At 9 months, the fetus is fully developed and ready for birth. It is 19-20 inches long and weighs 7-7.5 pounds. The lungs are mature and the fetus can survive outside the womb. The skin is pink and smooth, and the fetus settles lower in preparation for birth.

Work-life balance as a tool for employee satisfaction and retention - Jose Fe...EUR ING Jos Fernandes, M.Sc. ENG., MBA., MBA., GDBA.
This document provides a theoretical analysis of work-life balance as a tool for employee satisfaction and retention. It establishes the concepts of retention and employee satisfaction, and links them through empirical research. It defines work-life balance and discusses its historical context. The document argues that organizations can increase employee life satisfaction through work-life balance programs, creating a positive spill-over effect on job satisfaction. This can help with retention by increasing productivity and job satisfaction while reducing turnover intentions. Challenges to implementing work-life balance are also discussed.Vous plaisantez, non?

Baby development
During the first trimester, the fertilized egg implants in the uterus and develops major organs. By the 9th week it is called a fetus. In the second trimester, the uterus grows in size and movements from the fetus can be felt around 18-22 weeks. The fetus is about 10 inches long and 1.5 pounds by this time. In the third trimester, the fetus' organs continue maturing and it grows larger, settling head-down in preparation for delivery between 37-42 weeks of pregnancy.
Fetal development
The document describes fetal development from conception through the three trimesters of pregnancy. It explains that a baby is considered a newborn from birth to 28 days old, an infant from 1-12 months, and a toddler from 1-3 years old. Conception begins with fertilization, where an egg and sperm unite to form a zygote. The zygote then implants in the uterus and develops into an embryo for the first 8 weeks. After 8 weeks it is called a fetus. Each week of pregnancy is described in detail, outlining physical changes and growth of the fetus. The document concludes that a normal pregnancy lasts about 40 weeks.
Fetal development
The document discusses fetal development from conception through the three trimesters of pregnancy. It describes the major developmental milestones that occur each week, beginning with fertilization in week 3 and implantation in week 4. The embryonic period begins in week 5 as organs start to form. By week 8, arms and legs are growing and eyes are visible on the embryo, which becomes known as a fetus after 8 weeks. The document then outlines the key changes that happen each week through the remainder of pregnancy, with organs continuing to develop and the fetus growing larger until birth around week 40.
Fetus GROWTH AND ITS INFLUENCE ON DRUGS
The document discusses fetal growth and development and how drugs can influence it. It describes the typical stages of fetal growth from the pre-embryonic stage through the fetal stage. Key aspects of growth are covered for each trimester of pregnancy. Factors that can affect fetal growth like genetics, maternal health, nutrition, and drug use are examined. The risks of drugs passing from the mother to the fetus are summarized, including potential direct harm to the fetus or indirect issues from reduced blood flow or oxygen. Strict evaluation of drug safety during pregnancy is needed given limited research.
Pregnancy & you
This document provides an overview of pregnancy in 3 sentence summaries for each trimester:
The first trimester covers weeks 1-12, where fertilization occurs within the first few weeks and the fetus' major organs begin to develop through the first 12 weeks. The second trimester spans weeks 13-27, where major development occurs like the sex becoming apparent and skeleton formation. The third trimester is weeks 28 until birth, where the fetus gains weight, practices breathing, and organs become ready to function on their own by 37 weeks.
ppt on FETAL DEVELOPMENT class 12 in depth.pptx
This document discusses fetal development from conception through the three trimesters of pregnancy. It begins with definitions of fetus and outlines the germinal and embryonic stages when the fetus forms. It then describes the development that occurs in each of the three trimesters, including physical changes and growth. The document also discusses nutrition needs for the mother and fetus as well as potential pregnancy complications.
Fetal development
1. Fetal development occurs in three main stages - the pre-embryonic period from weeks 1-2 where rapid cell multiplication occurs, the embryonic period from weeks 3-8 where major organ systems develop, and the fetal period from weeks 9 until birth where the fetus continues to grow and develop.
2. During the pre-embryonic period the zygote travels through the fallopian tube and undergoes cell division, and in the embryonic period the major organs begin to form.
3. In the fetal period from months 3-9 the fetus continues to develop and grow, with all essential external and internal structures present by the end of the embryonic period, and the fetus gaining weight and length throughout
PRENTAL DEVELOPMENT PPT_20240117_235400_0000.pdf
The document summarizes the key stages of prenatal development from conception through birth in 3 months. During the first month, the zygote forms and begins cell division. In the second month, the embryo develops organs and the placenta forms. The third month sees further development of features and organs. The fetal period in months 4-9 sees continued growth and maturation of all body systems. By the end of the 9 months, birth occurs and development is complete.
Presentation1
Pregnancy typically lasts about 40 weeks and is divided into three trimesters. The first trimester lasts until 12 weeks and includes fertilization and implantation. In the second trimester from weeks 13 to 27, major organs develop and movement can be felt. The third trimester from weeks 28 to 40 includes further physical development and growth until birth.
Pregnancy- Human Development
This document outlines the psychological, physical, and developmental changes that occur during pregnancy for both the mother and baby. For the mother, common psychological effects include mood swings, anxiety, and body image issues. Physically, the body undergoes changes like weight gain and breast enlargement. Each trimester comes with its own set of symptoms. For the baby, development occurs in germinal, embryonic, and fetal stages. Key milestones are noted for weeks 9-38, such as organ formation, movement, and growth. Maintaining nutrition and exercise is important for both mother and baby's health.
Pregnancy
The document discusses the psychological and physical effects that a mother experiences during each trimester of pregnancy. In the first trimester, mothers often experience mood swings, anxiety about miscarriage and the health of the baby. Physically, they may have morning sickness, fatigue, and breast changes. The second trimester brings back pain, weight gain, and nausea. By the third trimester, mothers face fears around labor and delivery along with symptoms like hemorrhoids and shortness of breath. Throughout pregnancy, maintaining good nutrition, exercise, and paying attention to red flag symptoms is important for the health of the mother and baby.
Beyond fertilization
This document summarizes the key stages of human development from fertilization through pregnancy. It describes the processes of cleavage, morphogenesis, differentiation and growth that occur during embryogenesis. The stages of development from morula to blastocyst to embryonic disk are outlined. During the trimesters of pregnancy, the placenta forms and the embryo embeds in the uterus while organs and limbs develop. Fetal circulation and extraembryonic membranes such as the chorion, amnion and yolk sac are discussed. The document concludes with a description of parturition and birth.
Pregnancy-Fetal development.ppt
The document provides information about pregnancy and fetal development from fertilization through the first, second, and third trimesters. It describes how the embryo implants in the uterus and develops organs and limbs over the course of weeks. The placenta and umbilical cord form to support the growth of the fetus and allow nutrient exchange with the mother. The fetus' movements begin at 9 weeks and its sex may be apparent at 11 weeks.
Pregnancy
The fertilized egg moves down the fallopian tube and implants in the uterus. It grows into an embryo, then a fetus. The placenta links the fetus and uterus, allowing transfer of oxygen, food and waste while keeping the blood separate. After two months, the fetus is too big for the uterus wall and connects to the placenta via the umbilical cord. The process takes about 38 weeks until birth, controlled by hormones and resulting in contractions pushing the baby out through the cervix.
Got knocked up
The document discusses the three trimesters of pregnancy. It notes that fertilization occurs when the egg and sperm meet in the fallopian tubes, and it takes about two weeks to know if the egg is fertilized. The first trimester involves development of the placenta and basic body structures. The second trimester sees the fetus grow to about 25 cm and develop features like eyebrows. The third trimester involves rapid growth and strengthening of bones and muscles until birth.
Prenatal Development.pptx
The document summarizes the three stages of prenatal development: the germinal period, embryonic period, and fetal period. During the germinal period, the zygote attaches to the uterine wall about 6-7 days after fertilization. In the embryonic period from weeks 2 to 8, precursors to organs and structures form except sex organs. The fetal period begins at 8 weeks when the fetus resembles a human and is complete with organs; during the third month the fetus develops skeletal and neurological structures.
A week by week guide to pregnancy
This document provides a week-by-week guide to pregnancy from weeks 1 through 40. Each month covers 4 weeks and details the key physical changes occurring with the mother and development of the baby. In the first month, the baby's sex is determined and major organs begin to form. By month 2, all vital organs are in place and the baby resembles a tadpole. In month 3, the baby has human features and fingerprints develop. The guide covers maternal symptoms and advice for each stage of pregnancy through to birth.
1st-8th week of pregnancy
During weeks 1-3 of conception, the egg and sperm unite in the fallopian tube to form an embryo. The embryo then implants in the uterus and the placenta begins to form. In week 4, major organ formation begins as the embryo grows to be 10,000 times larger. By week 5, the heart beats and the eyes, nose, and limbs begin to form.
Fetus Development
Over the course of the nine month pregnancy, the fetus develops through three trimesters. In the first trimester, the zygote implants in the uterus and rapidly divides, with major organs beginning to form by week 5. The fetus' limbs, fingers and toes develop, and it begins to move independently by the end of the trimester. In the second trimester, the fetus grows significantly as its organs continue to mature and develop. By week 20 the mother may feel movements, and sex can be determined. The third trimester sees further growth and neurological development, with the fetus considered full term by week 37 and able to survive outside the womb by week 34.
Pregnancy and childbirth
The document discusses the stages of pregnancy and childbirth. It describes how an embryo develops into a fetus over the course of pregnancy. During the embryo stage from weeks 1-8, major organs begin to form. From weeks 9-birth, it is called a fetus and continues to grow and develop fully formed features. Childbirth occurs when contractions push the baby through the birth canal. The placenta and amniotic sac provide nutrients and protection for the growing fetus.
