Blood vessels form a closed system that begins and ends at the heart. There are three main types of blood vessels - arteries, which transport blood away from the heart; capillaries, which allow for exchange of materials between blood and tissues; and veins, which carry blood from the capillaries back towards the heart. Arteries branch into smaller arteries and then arterioles, which feed into capillary beds. Blood then drains from the capillaries into venules and veins of increasing size until emptying back into the heart, completing its 60,000 mile journey through the body transporting blood to and from tissues.

Heart
The three main chambers of the heart are the two atria which receive blood, and the two ventricles which pump blood out of the heart. The right side receives deoxygenated blood and pumps it to the lungs, while the left side receives oxygenated blood from the lungs and pumps it out to the body. One-way flow is ensured by atrioventricular and semilunar valves. The cardiac cycle involves the coordinated contraction and relaxation of the heart chambers.
Circulatory System.ppt
The circulatory system transports blood around the body using the heart as a pump and a network of arteries, veins and capillaries. Deoxygenated blood enters the right side of the heart and is pumped to the lungs, where it receives oxygen and returns to the left side to be pumped through the body. Blood pressure is highest when the heart contracts and lowest when it relaxes. Nerves regulate heart rate and blood vessel diameter in response to stress and activity levels.
Vascular system physiology
The document summarizes key aspects of the vascular system including the arterial, arteriolar, capillary and venous components. It notes that large elastic arteries like the aorta have a windkessel effect where they stretch during systole to prevent a rise in blood pressure and recoil during diastole to push blood forward and lower blood pressure. Arterioles are resistance vessels where sympathetic vasoconstriction occurs. Capillaries have the maximum total cross-sectional area for exchange of gases, nutrients and waste. Veins contain over half the blood volume and have lower elasticity than arteries.
Cardiovascular system
The document provides an overview of the human cardiovascular system. It describes the structure and function of the heart, including the layers of the heart wall, valves, conduction system, and heart sounds. It discusses the role of arteries, veins, and capillaries in circulating blood throughout the body and exchanging gases and nutrients at the tissue level. It also covers cardiac cycle, heart rate regulation by the autonomic nervous system, effects of ions like potassium and calcium on heart function, and factors influencing blood pressure.
Properties of blood vessels
William Harvey was the first modern physiologist in the 16th century. He proved that blood circulates in a continuous loop from the heart to the arteries and back to the veins and heart, overturning the long-held Galenic view of two separate circulatory systems. The circulatory system consists of arteries, which carry blood away from the heart; capillaries, where gas and nutrient exchange occurs; and veins, which carry blood back to the heart. Arteries have thicker muscular walls than veins and carry oxygenated blood except in the pulmonary circulation.

List the components of examination of Cardiovascular System.
Define cardiac cycle and its phases.
Define venous return, stroke volume, cardiac output, preload, afterload and ejection fraction with their normal range.
Blood vessels physiology
The document discusses capillary exchange and hemodynamics. It explains that capillaries allow exchange of substances between blood and tissues via diffusion, transcytosis, and bulk flow. Most exchange occurs via diffusion down concentration gradients. Bulk flow involves filtration of fluid from arteries into tissues and reabsorption into veins. Edema can occur if filtration exceeds reabsorption. Hemodynamics influence blood flow - it is highest where pressure differences are largest and resistance is lowest, such as from arteries to veins.
Anatomy of heart
The heart is a hollow, muscular pump located in the chest cavity. It has four chambers - two upper atria which receive blood, and two lower ventricles which pump blood out. The left side of the heart pumps oxygenated blood through the body, while the right side pumps deoxygenated blood to the lungs. The heart works nonstop to circulate over 5 liters of blood daily through over 100,000 km of blood vessels. It is innervated by the autonomic nervous system which controls heart rate and contraction force.

The cardiovascular system circulates blood throughout the body using the heart as a pump. The heart has four chambers - two upper atria and two lower ventricles. It is surrounded by membranes and tissues. Blood enters the right atrium from the body, then passes to the right ventricle which pumps it to the lungs. Oxygenated blood returns to the left atrium and passes to the left ventricle which pumps it out to the body via the aorta. The heart contracts over 100,000 times per day to circulate blood through the pulmonary and systemic circuits. Valves ensure blood only flows in one direction through the heart.
Circulatory system.ppt
The circulatory system consists of the cardiovascular system and lymphatic system. The cardiovascular system includes the heart and blood vessels that circulate blood throughout the body. It transports oxygen, nutrients, hormones, and immune cells and removes carbon dioxide and wastes. The circulatory system is divided into the systemic and pulmonary circuits. Arteries branch into smaller arterioles and capillaries, where gas and nutrient exchange occurs, before venules and veins return blood to the heart. The lymphatic system drains excess fluid from tissues and transports it back to the bloodstream.
CARDIOVASCULAR-SYSTEM-Group-6.docx
The cardiovascular system consists of the heart and blood vessels, and has three main functions:
1. Circulate oxygenated blood to tissues and organs via the circulatory system
2. Transport nutrients to and remove waste from all body cells
3. Maintain homeostasis in the body through regulated blood flow
The three main components are the heart, blood, and blood vessels. The heart pumps blood through a closed
system of arteries, veins, and capillaries to provide cells with oxygen and nutrients while removing carbon
dioxide and other wastes.
Blood circulatory sytem
The circulatory system contains blood, blood vessels, and the heart. The heart pumps blood through a closed double circulatory system, where blood is pumped from the heart through arteries, then capillaries, then veins, and back to the heart. Blood carries oxygen, nutrients, waste, hormones, and other materials between tissues and organs through this circulatory loop. The main components include the heart, arteries and veins, and blood itself which contains plasma, red blood cells, white blood cells, and platelets.

Cellular Respiration - AP Biology
Metabolism involves the chemical processes that take place in organisms. There are two main types of metabolic pathways - catabolic pathways that break down molecules and release energy, and anabolic pathways that use energy to build molecules. Cellular respiration uses catabolic pathways to break down glucose and other food molecules, releasing energy that is captured in ATP. There are four main stages of cellular respiration: glycolysis, pyruvate oxidation, the citric acid cycle, and the electron transport chain. When oxygen is absent, cells carry out anaerobic respiration like lactic acid fermentation or alcoholic fermentation to regenerate NAD+ and allow glycolysis to continue producing a small amount of ATP.
2018 Candidate - Rough Endoplasmic Reticulum
The rough endoplasmic reticulum (ER) is a network of membranes found throughout the cell that has ribosomes attached to its surface. It plays a key role in protein translation by reading DNA instructions to synthesize and package proteins with its coworkers like the Golgi apparatus and ribosomes. The rough ER is vital for producing proteins according to the cell's genetic blueprint.
2018 Candidate - Ribosomes
Ribosomes are organelles found in all cells that are responsible for protein synthesis. They produce proteins using mRNA and tRNA to translate DNA codes based on a cell's needs. Ribosomes have a small and large subunit and can be free-floating or attached to the endoplasmic reticulum. They produce essential proteins for cellular functions and structures like microtubules, centrioles, and histones. Dysfunction or mutations in ribosomal production can lead to diseases.
2018 Candidate - Nucleus & Nucleolus
The nucleus and nucleolus are running for president and vice president of the cell. The nucleus is described as the brain and leader of the cell, containing the DNA and directing major cellular activities. The DNA in the nucleus allows for protein synthesis. The nucleolus is the largest organelle in the nucleus and acts as the ribosome factory, regulating protein and cellular functions. It has a dense fibrilla component, fibrilla centers, and granular components that make up its structure.
2018 Candidate - Mitochondria & Chloroplast
The document summarizes the structure and function of mitochondria and chloroplasts. Mitochondria are double-membrane organelles that perform cellular respiration to convert nutrients into energy in the form of ATP. They evolved from engulfed prokaryotes and have their own DNA. Chloroplasts also evolved from engulfed prokaryotes and are located in plant cells. They capture light energy through photosynthesis to produce sugars and release oxygen. Mitochondria and chloroplasts work together to produce the energy needed for life.
Orientation of the Human Body - 2017
This document provides an overview of anatomy and physiology. It introduces key concepts like structural organization, homeostasis, and how structures and functions complement each other. It defines anatomy as the study of body structures and their relationships, while physiology is the study of how body parts function and systems process. Topics of anatomy include gross, microscopic, and developmental anatomy. Physiology topics include organ systems like renal, neurological, and cardiovascular. Homeostasis describes the body's ability to maintain stable internal conditions despite external changes through negative and positive feedback mechanisms. The document also reviews anatomical terminology including anatomical position, directional terms, body planes, and body cavities.
The Immune System
The immune system protects the body from infection and disease. It has both innate (nonspecific) defenses that provide immediate response and adaptive (specific) defenses that provide long-term protection. The innate system includes physical and chemical barriers that prevent pathogen entry. If barriers are breached, inflammation responds. The adaptive system recognizes specific pathogens using B cells and T cells. It has memory to mount stronger responses. Diseases can compromise immune function.
The Lymphatic System
The lymphatic system consists of lymphatic vessels and lymphoid tissues that work with the circulatory and immune systems. The lymphatic vessels collect excess fluid from tissues and return it to the bloodstream to prevent fluid buildup. They also transport immune cells called lymphocytes throughout the body. Lymphoid tissues including the spleen, tonsils, adenoids, and lymph nodes filter the lymph and help the body fight infection and disease.
Gases
1) Pressure is defined as force per unit area. The greater the force on a given area, the greater the pressure.
2) Gas pressure is caused by collisions of gas molecules with each other and surfaces. The pressure exerted by a gas depends on its volume, temperature, and number of molecules.
3) Boyle's law, Charles' law, and Gay-Lussac's law describe the relationships between pressure, volume, and temperature for an ideal gas. Boyle's law states that pressure and volume are inversely proportional at constant temperature. Charles' law states that volume and temperature are directly proportional at constant pressure. Gay-Lussac's law states that pressure and temperature are directly proportional at constant
Forensic Science
Forensic science is the application of science to address legal matters. It involves using various scientific techniques to analyze evidence found at crime scenes. Some key areas of forensic science include analyzing fingerprints, DNA, ballistics, toxicology, pathology, entomology, questioned documents, and trace evidence. The goal is to apply scientific processes and reasoning to help determine exactly what happened in criminal cases.
New evolution
This document discusses evolution as biology's unifying theme. It provides background on Charles Darwin and the development of his theory of evolution by natural selection. It describes Darwin's voyage on the HMS Beagle where he was struck by the variety of life and differences between species on islands in the Galapagos archipelago. Darwin realized all life on Earth descended from common ancestors and evolved through natural selection, with traits becoming adapted to local environments over generations. His theory revolutionized biology by explaining life's unity and diversity through evolution.
Genetic Mutations 2
Genetic mutations are changes in DNA sequence that can be caused by environmental factors or spontaneously. There are three main types of mutations: point mutations which change a single base pair, frameshift mutations which add or delete a base changing subsequent amino acids, and chromosomal mutations such as deletions, insertions, inversions or translocations of chromosome segments. Mutations can cause genetic disorders like cystic fibrosis, osteogenesis imperfecta, multiple neurofibromatosis, Klinefelter syndrome, twin-to-twin transfusion syndrome, fragile X syndrome, and Tay-Sachs disease.
Genetic Mutations 1
This document discusses different types of genetic mutations including point mutations, frameshift mutations, and chromosomal mutations. Point mutations involve a change in a single DNA base pair and may not significantly impact protein function, while frameshift and chromosomal mutations are more likely to cause problems. Chromosomal mutations include deletions, insertions, inversions, and translocations that alter chromosome structure. Environmental factors and spontaneous errors can cause genetic mutations, leading to disorders such as cystic fibrosis, fragile X syndrome, and Tay-Sachs disease.
Blood
Blood is composed of plasma and formed elements including red blood cells, white blood cells, and platelets. Red blood cells carry oxygen and carbon dioxide throughout the body. White blood cells help protect the body from infection and disease. Platelets are cell fragments that help form blood clots to stop bleeding. Careful matching of blood types is important for safe transfusions, as incompatible blood can cause a dangerous immune response.
DNA Replication and Protein Synthesis
The document discusses the benefits of exercise for mental health. Regular physical activity can help reduce anxiety and depression and improve mood and cognitive functioning. Exercise causes chemical changes in the brain that may help boost feelings of calmness, happiness and focus.
DNA Replication and Protein Synthesis
The document summarizes the processes of DNA replication and protein synthesis. DNA replication involves separating DNA into two strands and using each strand as a template to make an identical copy, resulting in two double-stranded DNA molecules. Protein synthesis involves transcription of DNA into mRNA, which is then translated on ribosomes into a polypeptide chain using transfer RNA to add amino acids specified by mRNA codons.
DNA History & Structure
The document discusses the history and structure of DNA. It describes how DNA was discovered to be the genetic material through experiments in the 1800s and 1900s. Key figures like Watson, Crick, Franklin and Chargaff contributed to determining DNA's double helix structure and the rules of base pairing between A-T and G-C. The structure forms a spiral with the bases on the inside and a sugar-phosphate backbone on the outside, held together by hydrogen bonds between the paired bases.
Chapter 6
Chemical bonds form between atoms to achieve more stable arrangements with lower potential energy. The type of bonding depends on differences in electronegativity between atoms. Ionic bonds form between ions, covalent bonds involve shared electron pairs, and metallic bonds result from delocalized electrons shared among many atoms in a lattice. Molecular geometry and intermolecular forces also influence molecular properties.
Cell Respiration
Metabolism involves the chemical processes that take place in organisms. There are catabolic pathways that break down molecules and release energy, and anabolic pathways that use energy to build molecules. Energy exists in different forms like kinetic and potential energy, and transformations are governed by thermodynamics laws. Cellular respiration uses energy from food molecules and involves glycolysis, breakdown of pyruvic acid, the citric acid cycle, and the electron transport chain, requiring oxygen. Without oxygen, anaerobic respiration like lactic acid fermentation allows glycolysis to continue to produce ATP.

LAND USE LAND COVER AND NDVI OF MIRZAPUR DISTRICT, UP
This Dissertation explores the particular circumstances of Mirzapur, a region located in the
core of India. Mirzapur, with its varied terrains and abundant biodiversity, offers an optimal
environment for investigating the changes in vegetation cover dynamics. Our study utilizes
advanced technologies such as GIS (Geographic Information Systems) and Remote sensing to
analyze the transformations that have taken place over the course of a decade.
The complex relationship between human activities and the environment has been the focus
of extensive research and worry. As the global community grapples with swift urbanization,
population expansion, and economic progress, the effects on natural ecosystems are becoming
more evident. A crucial element of this impact is the alteration of vegetation cover, which plays a
significant role in maintaining the ecological equilibrium of our planet.Land serves as the foundation for all human activities and provides the necessary materials for
these activities. As the most crucial natural resource, its utilization by humans results in different
'Land uses,' which are determined by both human activities and the physical characteristics of the
land.
The utilization of land is impacted by human needs and environmental factors. In countries
like India, rapid population growth and the emphasis on extensive resource exploitation can lead
to significant land degradation, adversely affecting the region's land cover.
Therefore, human intervention has significantly influenced land use patterns over many
centuries, evolving its structure over time and space. In the present era, these changes have
accelerated due to factors such as agriculture and urbanization. Information regarding land use and
cover is essential for various planning and management tasks related to the Earth's surface,
providing crucial environmental data for scientific, resource management, policy purposes, and
diverse human activities.
Accurate understanding of land use and cover is imperative for the development planning
of any area. Consequently, a wide range of professionals, including earth system scientists, land
and water managers, and urban planners, are interested in obtaining data on land use and cover
changes, conversion trends, and other related patterns. The spatial dimensions of land use and
cover support policymakers and scientists in making well-informed decisions, as alterations in
these patterns indicate shifts in economic and social conditions. Monitoring such changes with the
help of Advanced technologies like Remote Sensing and Geographic Information Systems is
crucial for coordinated efforts across different administrative levels. Advanced technologies like
Remote Sensing and Geographic Information Systems

Changes in vegetation cover refer to variations in the distribution, composition, and overall
structure of plant communities across different temporal and spatial scales. These changes can
occur natural.

Chapter 20
- 2. Overview • Blood vessels form a closed delivery system that begins and ends at the heart. • Three major types of blood vessels are: – Arteries – Veins – Capillaries
- 3. Overview • As the heart contracts, it forces blood into the large arteries leaving its ventricles. • The blood moves into successively smaller arteries, finally reaching their smallest branches, the arterioles, which feed into the capillary beds of body organs and tissues.
- 4. Overview • Blood draining from the capillaries flows into venules, and then on into small veins that merge to form larger veins that ultimately empty into the heart. • Altogether, the blood vessels in the adult human carry blood on a journey that stretches from about 60,000 miles through the internal body landscape!
- 7. Arteries • Arteries are vessels that transport blood away from the heart. • In terms of relative size and function, arteries can be divided into 3 groups: – Elastic arteries – Muscular arteries – Arterioles
- 8. • Elastic Arteries – Elastic arteries are the thick-walled arteries near the heart – the aorta and its major branches. • Muscular Arteries – The muscular arteries deliver blood to specific body organs and account for most of the named arteries studied in anatomy. • Arterioles – The arterioles are the smallest arteries.
- 9. Capillaries • Capillaries are the smallest blood vessels. • Their role is exchange of materials between the blood and interstitial fluid.
- 10. Veins • Blood is carried from the capillary beds toward the heart by veins. • Venules are formed when capillaries unite and veins are formed when venules unite. • Veins accommodate a fairly large blood volumes – up to 65% of the total blood supply.
