The lymphatic system is made up of lymphatic vessel and lymphatic organs. The lymphatic system has four main functions; lymphatic capillaries absorb excess tissue fluid and return it to the bloodstream. In the small intestines, lymphatic capillaries called lacteals absorb fats in the form of lipoproteins and transport them to the bloodstream. The lymphatic system also is responsible for the production, maintenance and distribution of lymphocytes. It also helps defend the body against pathogens.
Each renal artery enters its respective kidney at the renal hilus and divides into interlobar arteries. These arteries divide into smaller arcuate arteries and interlobular arteries. The smallest branches of the interlobular arteries are the afferent arterioles which carry blood into the glomerulus a knot of capillaries at the core of each nephron. The afferent arterioles are also lined with juxtaglomerular cells which help to control blood pressure.Each glomerulus is surrounded by a cup-shaped structure call Bowman's capsule. The blood pressure in the glomerulus is high enough that about 10% of the blood fluid volume is squeezed out and absorbed by the Bowman's capsule.
The cystic artery’s function is to supply passage of oxygenated blood to the gallbladder neck and the common bile duct. 16. What is the function of the portal vein? The portal vein carries blood that contains digested food from the small intestine to the liver. 17.
Plasma and red blood cells transport substances to or away from cell. White blood cells and platelets are parts of the immune system. Blood plasma is mostly made up of water which is from respiration and is absorbed from the large intestine. Water can also be reabsorbed from the kidney. This is very important as this allows osmosis occurs in our bodies.
Whenever a mineral is needed hormone signals are sent to the bones and the mineral that is needed is released into the blood stream. Vitamin D is needed for bones to properly absorb and store these minerals. 2) Flat bones provide extensive surfaces for muscles to attach. Muscles attach to flat bones to help provide movement of the arms and legs. Flat bones provide protection for the internal organs including the brain, heart, lungs, liver and kidneys.
The myocardium is the middle layer and is the muscle tissue and majority of the heart. The myocardium is what causes the heart to contract. The heart consists of four heart chambers which receive the blood that circulates through our body. The two main chambers are the right atria and the left atria and the two other chambers are called the right ventricle and the left ventricle. The atria deliver blood the ventricles.
The Lymphatic System P7 Unit 11 P7: The lymphatic system runs through our bodies and is made up of organs and lymphatic tissues. The types of organs are organs such as the spleen and thymus, the lymphatic tissue like lymphatic capillaries, vessels and nodes. The function of the lymphatic system is the draining of interstitial fluid, the transportation of lipids and the fighting of infections, these components (spleen, thymus, lymphatic capillaries, vessels and nodes) help to achieve the systems function. The lymphatic capillaries are blind end tubes and are larger than blood capillaries, they also have a unique one-way structure that allows interstitial fluids to enter but not exit, and they are very permeable. The Lymphatic capillaries aren’t located everywhere in the body, for example they are not found in our nervous tissue, the brain or spinal cord.
One realizes the importance of understanding the circulation system when you consider the fact that impairment to blood supplies is the leading cause of lesions in the central nervous system. It is also important to have knowledge of the distribution of blood in the brain via the various branches, since any interruption in the blood supply is often associated with characteristic neuropsychological signs and symptoms. Blood transports oxygen and other nutrients necessary for the health of neurons, so a constant flow of blood to the brain must be maintained. 1.1 SUBCLAVIAN ARTERY: The main artery of the body is called the aorta. It supplies blood to all parts of the body with the exception of the lungs.
| Circulatory system | | The human circulatory system (simplified). Red indicates oxygenated blood, blue indicates deoxygenated. (Not depicted are the intricate network ofcapillaries, as well as the entire lymphatic system.) | Latin | systema cardiovasculare | The circulatory system is an organ system that passes nutrients (such as amino acids, electrolytes and lymph), gases, hormones, blood cells, etc. to and from cells in the body to help fight diseases, stabilize body temperature and pH, and to maintainhomeostasis.
Body I. Blood I s produced by the bone marrow inside your bones. A. Here three kinds of blood cells are produced: red blood cells, disease fighting white blood cells, and blood clotting platelets B. From the bone marrow these cells enter the circulatory system, your blood vessels.
