6°lezione di introduzione all'Antico Testmento: il periodo monarchicosguazzo
Nella sesta lezione del nostro corso di itnroduzione all'Antico Testamento parleremo della nascita del regime monarchico in Israele, della figura di Davide e di Salomone e della divisione del regno. Infine commenteremo Isaia 7 che narra un momento centrale della guerra Siro- Efraimita
1. The male gamete (sperm) fuses with the female gamete (ova/egg) during fertilization to form a zygote.
2. The zygote develops into an embryo, which implants in the uterus and develops further into a fetus through the roles of the placenta and umbilical cord.
3. Childbirth occurs when contractions push the baby through the birth canal, after which the placenta detaches from the uterus and is delivered.
1. The document discusses reproduction in humans, including ante-natal care for the mother during pregnancy and care for the newborn baby. It emphasizes the importance of diet, exercise, and avoiding harmful substances during pregnancy.
2. Breastfeeding is described as important for providing nutrients and antibodies to help the baby grow and avoid infection. Other topics covered include birth control methods and some common sexually transmitted infections.

1. The male gamete (sperm) fuses with the female gamete (ova/egg) during fertilization to form a zygote.
2. The zygote develops into an embryo that is implanted in the uterus and receives nutrients via the placenta and umbilical cord without mixing of the mother and embryo's blood.
3. Childbirth is triggered by contractions that open the cervix and push the baby through the birth canal, after which the placenta detaches and is delivered.
The document describes human reproduction. It explains that sexual reproduction involves the fusion of male and female gametes. The male system produces sperm in the testes and transfers them via the sperm ducts. The female system contains ovaries which hold eggs from birth. At ovulation, an egg is released into the fallopian tubes where fertilization by sperm may occur, forming a zygote. The zygote implants in the uterus and develops via the placenta and umbilical cord until birth.
This document summarizes the processes of plant reproduction, including pollination and fertilization. It discusses:
- How pollen is transferred from the stamen to the carpel during pollination.
- The pollen tube grows and transfers the male gamete to the ovule contained in the ovary. Fertilization occurs when the male and female gametes fuse.
- After fertilization, the zygote develops into an embryo inside the seed. The ovary develops into fruit, protecting the seed until conditions allow for germination.
The document describes the structure and function of flower parts, including that flowers produce male and female gametes. Sepals protect the developing flower, petals attract insects for cross-pollination, the nectary produces nectar, the carpel contains ovules for female gamete production, and the stamen contains pollen grains with male gametes. Pollination is the transfer of pollen and can occur through insect-pollination, where insects carry pollen between flowers, or wind-pollination. Fertilization happens when pollen nuclei fuse with ovule nuclei.
Plants can reproduce both asexually and sexually. Asexual reproduction involves mitosis and results in offspring that are genetically identical to the parent. Sexual reproduction involves the fusion of male and female gametes, resulting in offspring with a unique combination of genes from both parents. Gametes are haploid cells that are formed through meiosis in the parent organism in order to combine and form a diploid zygote.
The hypothalamus regulates body temperature through negative feedback by sensing blood temperature and sending signals to alter processes like shivering, sweating and blood vessel constriction/dilation. The pancreas and liver also use negative feedback to keep blood glucose levels steady by secreting insulin and glucagon which signal the liver to store or release glucose as needed. Diabetes occurs when this process is disrupted, resulting in dangerous fluctuations in blood glucose.
Homeostasis refers to the maintenance of a constant internal environment in the body, keeping factors such as temperature, water concentration, and glucose levels stable despite changes in the external environment. This allows cells to function efficiently and prevents damage. Endothermic animals like mammals and birds internally regulate their body temperature, while ectothermic animals like reptiles rely on external temperatures. The skin plays an important role in homeostasis through its structure - the epidermis contains cells that protect the body and produce melanin and keratin, while the dermis contains sweat glands, blood vessels, and nerves that help regulate temperature.
This document discusses various drugs and their effects on the human body. It provides information on antibiotics and how bacteria are evolving resistance. It also discusses opioids like heroin and their addictive properties. The document covers alcohol consumption and alcoholism. It addresses anabolic steroids used for muscle growth and the health risks. Finally, it summarizes the harmful effects of smoking tobacco, including increased cancer and heart disease risks.
The endocrine system communicates messages via hormones released directly into the bloodstream from ductless glands. Hormones are carried throughout the body and affect target organs. Important endocrine glands include the adrenal glands, which secrete adrenaline in response to stress signals from the brain, causing effects like increased heart rate and breathing. Plants also respond to stimuli through hormones like auxin, which is produced in shoot tips and causes phototropism by stimulating faster growth on the shady side of shoots, bending them towards light sources.
This document summarizes several parts of the eye and vision system. It describes the main sense organs including the eye, ear, nose, tongue, and skin. It then focuses on the eye, explaining that the retina contains rod and cone cells that are receptors sensitive to light. The iris controls the size of the pupil to regulate the amount of light entering the eye. The lens focuses light onto the retina, where it is transmitted via the optic nerve to the brain to create an image.
The document discusses coordination between receptors and effectors in the body. It describes how stimuli are detected by receptors and responses are carried out by effectors, such as muscles and glands. There are two pathways for coordination - the nervous system, which uses nerves and electrical impulses, and the endocrine system, which uses hormones. The nervous system allows for very fast coordination, which is important for functions like hunting and avoiding predators. It then describes the basic anatomy and processes of the nervous system in more detail.
The human excretory system includes the kidneys, ureters, bladder, and urethra. The kidneys filter waste from the blood to produce urine via tiny tubules called nephrons. The urine travels from the kidneys down the ureters and into the bladder, where it is stored until excretion through the urethra. For those with kidney failure, dialysis provides an artificial filtration of the blood to remove waste, while transplantation involves surgically implanting a donor kidney to replace non-functioning ones.
Excretion is the removal of waste products from an organism. These waste products include the byproducts of metabolism like urea and ammonia, as well as toxic materials and substances in excess. Egestion refers specifically to the passing out of undigested food through the anus, whereas excretion removes metabolic waste products. In mammals, excess protein is broken down into urea in the liver through a process called deamination and then transported to the kidneys for excretion in urine. The liver plays an important role in metabolizing nutrients and filtering waste from the bloodstream.
The respiratory system allows for gas exchange in humans. Air enters through the nose or mouth and passes through the trachea into the lungs. In the lungs, the bronchi branch into smaller tubes called bronchioles that end in alveoli, which are tiny air sacs where gas exchange occurs. Oxygen from the inhaled air passes into the bloodstream, and carbon dioxide passes from the bloodstream into the alveoli to be exhaled. Breathing is driven by the diaphragm and intercostal muscles contracting and relaxing to expand and contract the lungs and chest.
This document discusses respiration and gas exchange. It explains that aerobic respiration uses oxygen to break down glucose, releasing carbon dioxide and water. Anaerobic respiration in yeast breaks down glucose into alcohol and carbon dioxide without oxygen. Anaerobic respiration in humans produces lactic acid instead of alcohol when oxygen cannot be supplied fast enough to muscles during vigorous exercise.
The document discusses how the immune system responds to pathogens. When a pathogen enters the body, lymphocytes recognize it and produce antibodies specific to that pathogen. The antibodies coat the pathogen and recruit phagocytes to destroy it. Memory cells remain after an infection to allow for a faster response if the same pathogen is encountered again. It takes time for antibodies to be produced and for the pathogen to be eliminated, during which time the pathogen may continue to reproduce. Vaccination provides active immunity by exposing the body to dead or weakened pathogens to stimulate memory cell production without causing disease.
A British woman visiting India was bitten by a dog but did not seek medical treatment. Seven weeks later back in Britain, she fell ill and doctors could not diagnose her mild symptoms. She was eventually taken to a specialist tropical diseases hospital where it was discovered she had rabies from the dog bite in India. Rabies is a viral disease transmitted through infected animal bites that is almost always fatal if left untreated.
The document discusses the circulatory system and blood transport in animals. It describes single and double circulatory systems. In a single circulation, blood travels from the heart to the gills to absorb oxygen and then to the organs before returning to the heart. In a double circulation, there are two circuits - one where blood passes from the heart to the lungs to absorb oxygen and release carbon dioxide, and another where blood passes from the heart to the organs and tissues to deliver oxygen before returning to the heart. A double circulation has evolved to create more pressure to pump blood around the system and separate oxygen-rich and oxygen-poor blood.
The document discusses the process of digestion. It begins with an overview of the alimentary canal and its parts, including the mouth, esophagus, stomach, small intestine, large intestine, and anus. It then covers the stages of digestion - ingestion, digestion, absorption, assimilation, and egestion. Specific topics covered include the roles and locations of enzymes in breaking down food, as well as the functions of organs like the liver, gallbladder and pancreas in digestion.
This document provides information about animal nutrition and balanced diets. It defines what a balanced diet is and lists the seven major types of nutrients: carbohydrates, proteins, fats, vitamins, minerals, water, and fiber. It describes the sources and functions of these nutrients and explains that an unbalanced diet can lead to deficiency diseases. Specific nutrient deficiencies that are discussed include vitamin C (scurvy), vitamin D (rickets), vitamin A (night blindness), calcium, and iron (anemia). The document also covers malnutrition conditions like marasmus and kwashiorkor that can result from poor nutrition.

4. Per rendere più comprensibile il suo messaggio, il
Signore mandò due visioni a Geremia.
5. Geremia annunciò che
la Palestina sarebbe
stata invasa dalla
Babilonia, ma nessuno
lo credette.
6. Il Signore ordinò a Geremia di tagliarsi i capelli,
come simbolo di lutto, di non sposarsi e di non avere
figli, come simbolo di assenza di speranza per Israele.
7. Il regno di Giuda termina con l'esilio della maggior parte dei
Guidei a Babilonia, per mano del re conquistatore
Nabucodonosor II. Quando la nazione fu conquistata dai
Babilonesi, Nabucodonosor ordinò la distruzione del Tempio
che fu bruciato.
8. Geremia fu risparmiato e lasciato vivere tra le rovine
di Gerusalemme, dove continuò a predicare.
9. Il profeta fu catturato dai suoi denigratori e portato
in Egitto, dove morì.
Egli fu un profeta molto importante nella storia di
Israele e per il cristianesimo poi.
10. Quello che Geremia vuole trasmettere è un
messaggio semplice: dobbiamo fidarci di
coloro che vengono in nome di Dio per
salvare il popolo.
