The main functions of the blood are to transport, defence, regulation and clotting. The oxygen is carried from the lungs to the cells of the body in red blood cells. Carbon dioxide is carried from the body’s cells to the lungs. Cellular waste such as water, carbon dioxide, lactic acid and urea are carried in the blood to be excreted. Hormones, internal secretions that help to control important body processes are also transported by blood to target organs.
P4: The Cardiovascular system The cardiovascular system refers to the heart, blood vessels and the systematic circulation (blood). Blood contains oxygen and other nutrients which your body needs to survive. The body takes these essential nutrients from the blood. At the same time, the body dumps waste products like carbon dioxide, back into the blood, so they can be removed. The main function of the cardiovascular system is therefore to maintain blood flow to all parts of the body, to allow it to survive.
| | Components and function of Blood Blood is used to transport materials around the body, and protect against disease. Blood contains plasma, a liquid that contains dissolved substance, cells and cell fragments. These include the following: Red blood cells | Transport oxygen – this cell in the blood of vertebrates that transports oxygen and carbon dioxide to and from the tissues. The red blood cell is disk; it contains hemogbin and lacks nucleus, | | White blood cells | Protect against disease - any of various blood cells that have a nucleus and cytoplasm, separate into a thin white layer when blood cells are separate from plasma cells, and help protect the body from infection and disease. White blood cells include – neutrophils, eosinophils, basophils, lymphocytes and monocytes.
Cardiovascular system The cardiovascular system consists of our heart (left and right ventricle, left and atrium, aorta, tricuspid valves, semi-lunar valves, vena cava, pulmonary artery and pulmonary vein), blood and blood vessels (renal artery, hepatic artery, renal vein and hepatic vein). The cardiovascular system is responsible for transporting nutrients and removing gaseous waste from the body. Digestive system The digestive system consists of the stomach, pancreas, liver, small intestine (duodenum, ileum and jejunum) and the colon (ascending colon, transverse colon, descending colon and sigmoid colon). The digestive system is used for digesting foods to a soluble form for the small intestine to absorb the minerals and vitamins and then what is left of the food is transported to the colon for water reabsorption and then excreted through the anus. Endocrine system The endocrine system is the system of glands, each of which secretes different types of hormones directly into the bloodstream to maintain homeostasis.
The blood vessels are a intricate network of tubes that transport blood throughout the body. These vessels carry blood from the heart via the arteries ,then arterioles, then to capillaries or sinusoids, to venules, to veins and back to the heart. The final component to this structure is blood that delivers nutrients and removes wastes that are a by product of cellular processes that happen within the body. What is its
The cardiovascular system is responsible for transporting nutrients and removing waste from the body as gas. The cardiovascular system consists of the heart and the circulatory system. The heart is the main organ of the body and it helps transport blood and oxygen around the body. The heart produces electrical impulses through a process called cardiac conduction. The impulses produced cause the heart to
The blood from these arteries feeds the organs and systems (cells & tissues). Once the blood has given up all its oxygen it makes its way back through the heart, through the veins. Blood from the lower part of the body enters the heart through the inferior vena cava. Blood from the top of the body enters the heart through the superior vena cava. Blood only flows in one direction through the heart; the two values (bicuspid & tricuspid) ensure that this happens.
Urinary and Reproductive Systems Dissection Urinary System Kidney The kidneys are paired organs with several functions. They are an essential part of the urinary system and serve homeostatic functions such as the regulation of electrolytes, maintenance of acid-base balance, and regulation of blood pressure. They serve the body as a natural filter of the blood, and remove wastes, which are diverted to the urinary bladder. In producing urine, the kidneys excrete wastes such as urea and ammonium; the kidneys also are responsible for the reabsorption of water, glucose, and amino acids. The kidneys also produce hormones including calcitriol, renin, and erythropoietin.
Furthermore they diffuse through plasma membranes of red blood cells and bind to the haemoglobin. By the cardiac cycle, oxygen gets transported to cells all over the body, where it’s used for aerobic respiration. One of the products during respiration is carbon dioxide. It is diffused in blood plasma and also transported by the cardiac cycle, back to the lungs. There the carbon dioxide will diffuse down the concentration gradient through endothelial cells in capillaries
This paper aims to describe the pathophysiology of atrial fibrillation and the rationale behind the information included in the patient education tool. Atrial Fibrillation: A Patient Education Guide The heart is a muscle that contains four chambers; the right atrium, left atrium, right ventricle, and left ventricle. Each of these chambers has a purpose. The right ventricle pumps blood to the lungs and the left ventricle pumps blood to the rest of the body. The right atrium receives deoxygenated blood via the superior and inferior vena cava.
