Blood
Blood is composed of cellular components called formed elements (red blood cells, white blood cells, and platelets) suspended in plasma. Red blood cells transport oxygen and carbon dioxide throughout the body. White blood cells help fight infection and disease. Platelets help control bleeding by initiating blood clotting. The bone marrow produces new blood cells through the process of hematopoiesis to replenish aging and damaged cells.
Physiology of Blood
Blood is composed of plasma and formed elements. Plasma contains water, proteins, glucose, salts, and other nutrients. Formed elements include red blood cells, white blood cells, and platelets. Hemostasis involves platelet plug formation and coagulation to prevent blood loss from damaged vessels. It is carefully regulated to maintain blood fluidity. The ABO blood group system involves antigens on red blood cells and antibodies in plasma. Compatible blood types are required for safe transfusions and pregnancies.
Physiology of the Endocrine System
The endocrine system is composed of organs positioned throughout the body in widely separated locations. Endocrinology is the study of the structure and functioning of the endocrine system.

Red blood cells contain hemoglobin which carries oxygen. White blood cells help fight infection. Platelets assist in blood clotting. The document discusses blood composition and formation, cell types and functions, hemostasis, and blood groups.
Erythropoiesis
This document discusses erythropoiesis, the production of red blood cells. It describes the stages of red blood cell development from stem cells to reticulocytes to mature red blood cells. Erythropoiesis is regulated by factors like erythropoietin and tissue oxygen levels. Erythropoietin is produced mainly in the kidneys and stimulates red blood cell production. Vitamins like B12 and folic acid are also essential for red blood cell maturation.
White blood cells / Leucocytes
White blood cells, also known as leukocytes, come in various types classified by their granule presence and cytoplasm staining. The five main types are granulocytes (neutrophils, eosinophils, basophils) and agranulocytes (lymphocytes, monocytes). Leukocytes are formed in bone marrow and live around 13-20 days, playing important roles in immunity and fighting infection and disease. Leukocyte disorders include increased or decreased cell counts caused by various infections, cancers, drugs, or medical conditions.

Haemopoiesis
Hematopoiesis is the process where blood cells are produced in the bone marrow from hematopoietic stem cells. In adults, red blood cells, white blood cells, and platelets are produced in the bone marrow from pluripotent stem cells. The stem cells differentiate into the various cell lineages through the effects of growth factors and cytokines. Erythropoietin regulates red blood cell production in response to tissue oxygen levels while granulocyte macrophage colony-stimulating factor regulates white blood cell production. T and B lymphocytes mature in different areas with T cells maturing in the thymus and B cells maturing in the bone marrow and spleen.

Histology of liver by aravindh dpi
The liver is composed of repeating lobules that contain hepatocytes radiating from a central vein. Between hepatocytes are sinusoids lined with endothelial cells and Kupffer cells. Bile canaliculi connect hepatocytes and drain bile into interlobular bile ducts. The perisinusoidal space of Disse contains fibers and lipocytes between sinusoids and hepatocytes. There are three types of lobules - classical with peripheral to central blood flow, portal defined by a bile duct, and acinar surrounding a central artery in three oxygen zones. Hepatocytes are polyhedral cells that contact sinusoids through spaces of Disse.

lekopoiesis
This document discusses leukopoiesis, the process by which white blood cells are formed. It explains that all blood cells, including white blood cells, are formed from pluripotent hematopoietic stem cells in the bone marrow. These stem cells can differentiate into either myeloid or lymphoid stem cells. Myeloid stem cells go on to produce red blood cells, platelets, monocytes, or granulocytes, while lymphoid stem cells produce lymphocytes. Leukopoiesis involves the maturation of these stem cells into the various types of white blood cells.
Blood anatomy and physiology
Blood carries oxygen, nutrients, hormones and waste products throughout the body. It is composed of plasma and formed elements including red blood cells, white blood cells and platelets. Red blood cells contain hemoglobin and transport oxygen, while white blood cells help fight infection. Platelets help form clots to stop bleeding. Blood type is determined by antigens on red blood cells and the presence of antibodies in plasma. A blood transfusion matches the donor's blood type to the recipient to avoid an immune reaction.
Blood
Blood has three main functions: transport, protection, and regulation. It transports gases, nutrients, hormones, heat, and waste throughout the body. Blood also protects the body through white blood cells that destroy pathogens and platelets that initiate clotting. Additionally, blood helps regulate pH, water balance, and other processes. Blood is composed of plasma, red blood cells, white blood cells, and platelets, each with distinct roles in these important functions.
Blood and coagulation
This document provides an overview of blood and its components. It discusses the properties, functions and composition of blood. The key components discussed in detail include red blood cells, white blood cells, platelets, coagulation and bleeding disorders. Red blood cells, white blood cells and platelets (formed elements) and plasma make up whole blood. Coagulation is the process by which blood changes from a liquid to a gel forming a clot. Bleeding disorders can be caused by issues with blood vessels, platelets, coagulation factors or fibrinolysis. Periodontal manifestations of various blood disorders are also summarized.
hematopioesis
Hematopoiesis is the production of blood cells, including erythrocytes, leukocytes, and thrombocytes, which occurs through several stages. It begins in the fetal liver and spleen and later transitions to the bone marrow, which remains the primary site of hematopoiesis in adults. The process involves pluripotent stem cells that differentiate into committed progenitor cells and eventually mature blood cell types through regulated stages of proliferation and maturation, guided by hematopoietic growth factors in the bone marrow microenvironment.
Ureter
The ureter is a narrow, thick-walled, muscular tube that conveys urine from the kidney to the urinary bladder. Peristaltic contractions of the smooth muscle in the ureter wall propel urine downward. The ureter has three layers of smooth muscle in the lower third and two layers in the upper two-thirds. It courses down the posterior abdominal wall and enters the pelvis, where it crosses the common iliac artery. In the pelvis, it travels laterally along the sciatic notch before entering the bladder obliquely. The ureter has several sites of anatomical narrowing where stones are prone to lodge, including at the pelvic brim and ure
Pancreatic juice...
The pancreatic juice is a transparent, isotonic fluid secreted by the pancreas. It has both endocrine and exocrine functions. The exocrine secretions contain digestive enzymes like amylase, lipase, and proteases that aid in digestion. Bicarbonate ions secreted in pancreatic juice neutralize the acidic chime from the stomach and provide an optimal pH for the enzymes. The secretions occur in three phases regulated by both the autonomic nervous system and hormones like secretin and cholecystokinin. Secretin increases the secretion of bicarbonate-rich fluid while cholecystokinin stimulates enzyme secretion after eating. Disorders like pancreatitis and cystic fibrosis can impair pancreatic function and digestion.
Leucopoiesis
1. The document discusses hematopoiesis, the formation and maturation of white blood cells (WBCs) including granulocytes, monocytes, and lymphocytes from stem cells in the bone marrow.
2. It describes the stages of development for granulocytes and monocytes, from stem cell to mature cell, including the changes in physical characteristics at each stage.
3. Lymphocytes develop from stem cells in the bone marrow and various lymph tissues, with T cells maturing in the thymus and B cells maturing in lymph nodes and spleen. Mature lymphocytes circulate in the blood and lymphatic systems.
Blood
This document discusses the composition and components of blood. It states that blood is composed of plasma and cells, with plasma making up 55% and cells 45%. The main cells are red blood cells, white blood cells, and platelets. Plasma contains 91% water and proteins like albumin, globulin, and fibrinogen. Red blood cells carry oxygen through hemoglobin and have a lifespan of 120 days. White blood cells provide immunity and come in two types - granulocytes and agranulocytes. Platelets help in blood clotting and have a lifespan of 5-9 days.
Platelets by Dr Prafull Turerao
Platelets are small cell fragments that help the blood clot. They adhere to damaged blood vessel walls, aggregate together, and release chemicals that promote clotting. Platelets are produced in the bone marrow from megakaryocytes in a process called thrombopoiesis. They have a lifespan of about 10 days before being destroyed by the spleen. The normal platelet count is 150,000-400,000 per microliter of blood. Platelet counts vary physiologically with age, being lower in infants, but not with sex.
Blood- composition and function
This presentation covers characteristics, composition, function and formation of blood and blood cells.
Blood Physiology - Ppt
Blood functions to transport oxygen, nutrients, waste, hormones, and more throughout the body. It is composed of plasma and formed elements including erythrocytes, leukocytes, and thrombocytes. Erythrocytes carry oxygen to tissues via hemoglobin and have a normal lifespan of 100-120 days before being recycled. The erythrocyte sedimentation rate is a common test measuring the rate at which red blood cells sediment in one hour, indicating inflammation.

This document is a PowerPoint presentation on blood cells submitted by Anusree.C to her lecturer Smt.Soya.P. It introduces the three main types of blood cells - erythrocytes (red blood cells), leukocytes (white blood cells), and platelets. It describes the functions of each cell type, including that red blood cells transport oxygen, white blood cells protect against infection, and platelets help the blood clotting process. Diagrams and details are provided about the shape and components of red blood cells and the different types of white blood cells.
Blood & its functions
The human body contains approximately 5 liters of blood composed of plasma and cellular elements. Plasma is 55% of blood and contains water, proteins, electrolytes, and other substances. Cellular elements include red blood cells containing hemoglobin, white blood cells for immunity, and platelets for clotting. Blood transports oxygen, nutrients, wastes, hormones, and more throughout the body.
Blood
1. Normoblasts are immature red blood cells that are similar in size to mature RBCs and stain almost the same as most ribosomes are lost and more hemoglobin accumulates.
2. Polychromatophilic erythrocytes or reticulocytes are formed when a normoblast loses its nucleus but still retains some ribosomes, giving it a pink-blue stained cytoplasm.
3. Basophilic and polychromatophilic erythroblasts are larger developing red blood cells where the nucleus is condensing and hemoglobin begins to accumulate in the cytoplasm, producing different staining patterns.

Anatomy Of Cardiovasvular System
Chapter 37- Circulatory and Respiratory Systems
The circulatory system transports blood throughout the body via the heart and blood vessels. The heart has four chambers and uses valves to pump oxygenated blood from the lungs and deoxygenated blood to the lungs. Blood flows through arteries, capillaries, and veins. The respiratory system exchanges gases through the nose, pharynx, trachea, bronchi, and alveoli in the lungs. Breathing is controlled by the medulla oblongata and diaphragm. Smoking damages lungs and increases risk of diseases like cancer, emphysema, and bronchitis.

Human systems
The circulatory system consists of the heart, blood vessels, and blood. The heart pumps oxygen-rich blood throughout the body via arteries and returns deoxygenated blood to the lungs via veins to become reoxygenated. The circulatory system transports nutrients, gases, hormones, blood cells, and wastes. It plays a key role in respiration, nutrition, and waste removal. Main components include the heart, blood vessels (arteries, veins, capillaries), and blood (plasma and blood cells).
Chapter 2 Blood Circulation and Transportation
The circulatory system transports blood throughout the body via arteries, veins and capillaries. Blood carries oxygen, nutrients, hormones and waste products. The heart pumps blood through two circuits - pulmonary circulation to the lungs and systemic circulation to the rest of the body. The document provides details on the structure and function of the heart, blood vessels, blood composition and the importance of blood donation.

The lymphatic system drains fluid from tissues and returns it to the blood.
Circulatory System
The circulatory system transports nutrients, gases, hormones, blood cells, etc. to and from cells in the body. It consists of the heart, blood vessels (arteries, veins, capillaries), and blood. The heart pumps blood through blood vessels to supply oxygen and remove carbon dioxide from tissues throughout the body. Blood contains plasma, red blood cells, white blood cells, and platelets. The circulatory system also helps fight infections and regulates body temperature.
Circulatory_System_7-8.ppt
The circulatory system, also known as the cardiovascular system, consists of the heart, blood vessels, and blood. It transports essential materials to cells and removes waste through two circulation routes: pulmonary circulation carries deoxygenated blood to the lungs to receive oxygen, and systemic circulation distributes oxygenated blood to all body tissues. The circulatory system is vital for cell function, immunity, waste removal, and maintaining homeostasis.
Stem12 circulatory system
The circulatory system transports essential materials to cells and removes waste through the cardiovascular system. It consists of the heart, blood vessels, and blood. The heart pumps blood through two circuits - pulmonary circulation carries deoxygenated blood to the lungs and systemic circulation distributes oxygenated blood to the entire body through arteries, veins, and capillaries. Problems can occur if blood pressure is too high or low or if blood flow is obstructed, as in heart attacks or strokes. A healthy lifestyle supports good circulatory health.
Circulatory system
The circulatory system transports blood, nutrients, gases, and waste throughout the body via blood vessels and the heart. It is composed of the cardiovascular system including the heart, which pumps blood, and blood vessels. The heart has four chambers that receive and pump blood into and out of the lungs and body. Blood contains red blood cells, white blood cells, and platelets and carries oxygen, nutrients, hormones, and removes waste. It flows through arteries, capillaries, and veins.
Cardio vascular system
The document provides information about the cardio-vascular or circulatory system. It describes that the system includes the heart, blood vessels (arteries, veins, capillaries), and blood. The heart pumps blood through the vessels, carrying oxygen and nutrients to tissues and removing carbon dioxide and waste. Key components discussed include the chambers and vessels of the heart, blood cells like red blood cells, white blood cells and platelets, and how blood clotting works. The document also covers some common blood-borne diseases like HIV/AIDS and types of hepatitis.
Circulatory system
The circulatory system consists of the heart, blood vessels, and blood. The heart pumps blood through a network of arteries, veins, and capillaries that extend over 60,000 miles throughout the body, delivering oxygen and nutrients to tissues and removing waste. Blood flows from the heart through arteries, into smaller arterioles and capillaries, then into venules and veins before returning to the heart. The circulatory system allows for the transportation of blood, oxygen, hormones, and other substances essential for life.
Nutrition II
The circulatory system consists of the heart, blood vessels, and blood. The heart pumps blood through arteries and veins, and into over 60,000 miles of capillaries that reach every cell. Blood carries oxygen, nutrients, hormones, and waste products. It contains plasma, red blood cells, white blood cells, and platelets. The kidneys and sweat glands help remove waste from the blood through urine and sweat. Proper hydration through drinking water is important for the circulatory system to function effectively.
Circulatory system
The circulatory system consists of the cardiovascular system and lymphatic system. The cardiovascular system includes the heart, blood vessels, and blood. It transports blood throughout the body, delivering oxygen and nutrients to tissues and removing waste. The lymphatic system collects excess fluid from tissues, transports it to lymph nodes, and returns it to the bloodstream. Both systems work together to circulate fluid throughout the body, support immunity and waste removal, and maintain homeostasis.
Circulatory System featuring blood heart and compositions
The document provides an overview of the circulatory system, including its main components and functions. It discusses the heart, arteries, veins, capillaries, blood, and diseases that can affect the circulatory system. The circulatory system transports oxygen, nutrients, hormones, and removes waste via the blood through blood vessels throughout the entire body, powered by the constant pumping of the heart. Key parts include the heart, blood, arteries, veins, and capillaries, each playing an essential role in circulation. Common diseases include atherosclerosis, which is the hardening of the arteries often due to a fatty diet.
Circulatory system
The circulatory system transports nutrients, oxygen, and wastes throughout the body via blood vessels. Blood is pumped from the heart through arteries, then into capillaries where nutrients and oxygen are exchanged, and finally returns to the heart through veins. The circulatory system consists of the heart, blood, and blood vessels which work together to transport blood containing red blood cells, white blood cells, platelets, and plasma to all parts of the body.
LIFE PROCESSES PART- 5.pptx
The document summarizes the transportation system in human beings. It describes how blood transports oxygen, nutrients, waste and other materials throughout the body using a network of blood vessels and the heart as the pumping organ. Blood is circulated via double circulation, where it passes through the heart twice - first to pick up oxygen in the lungs and then distribute it to tissues before returning to be reoxygenated. The system is maintained by platelets that help form clots to plug leaks in blood vessels. Lymph and tissue fluid also transport nutrients and remove excess fluid from tissues before returning to blood circulation.
The human body
The human body consists of a circulatory system that transports blood and oxygen throughout the body via arteries, arterioles, capillaries and veins. Blood is composed of blood cells suspended in plasma and performs vital functions like delivering oxygen and nutrients to tissues via the smallest blood vessels, capillaries. The components of blood that support these functions include plasma, red blood cells that carry oxygen, platelets that control bleeding, and white blood cells that fight infection.
Circulatory system mine for 3rd
The circulatory system transports blood throughout the body via the heart and blood vessels. The blood contains red blood cells, white blood cells, platelets and plasma. It carries oxygen, nutrients, hormones and waste products. The heart has four chambers that pump blood in two circuits - the pulmonary circulation and the systemic circulation. Deoxygenated blood is pumped from the heart to the lungs and returns oxygenated. It is then pumped through arteries, capillaries and veins to deliver oxygen and nutrients to tissues and remove carbon dioxide and other wastes.
The circulatory system
The circulatory system circulates blood through the heart and blood vessels to transport oxygen, nutrients, hormones, and waste products to and from cells. The heart pumps deoxygenated blood to the lungs to receive oxygen and pumps oxygenated blood to the rest of the body. Blood travels through arteries, veins, and capillaries, and contains plasma, red blood cells, white blood cells, and platelets to carry oxygen, fight infections, and help clotting.

The Tongue!!
The tongue is a muscle in the mouth that assists with chewing, swallowing, and speech. It is covered in taste buds and kept moist by saliva to help with tasting food and moving. Some people can roll their tongues or fold their tongues into a clover shape due to genetic factors. The tongue has many nerves and blood vessels and comes in varying lengths.
The Human Body
The heart is a muscle that pumps blood throughout the body, providing oxygen and nutrients and removing waste. It has four chambers and works as a pump, with the right side pumping blood to the lungs and left side to the rest of the body. The heart's rhythm is controlled by electrical impulses and it requires coronary arteries on the outside to supply its own muscle with oxygenated blood. High blood pressure can damage the heart over time if not managed.
