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.
The left and right side of the heart are separated by the posterior interventricular sulcus. The right side of your heart receives blood from the body and pumps it to the lungs. The left side of the heart does the exact opposite and receives blood from the lungs and pumps it out to the body. The Cardiovascular System works with the body’s Circulatory System and is responsible for distributing blood and nutrients throughout the body to maintain homeostasis. It then helps to pump blood around the body, to supply tissues with oxygen and nutrients and to transport waste products away from the tissues.
The circulatory system, also called the cardiovascular system, is an organ system that permits blood to circulate and transportnutrients (such as amino acids and electrolytes), oxygen, carbon dioxide, hormones, and blood cells to and from the cells in the body to provide nourishment and help in fighting diseases, stabilize temperature and pH, and maintain homeostasis. The study of the blood flow is called hemodynamics. The study of the properties of the blood flow is called hemorheology. The circulatory system is often seen to comprise both the cardiovascular system, which distributes blood, and the lymphatic system, which circulates lymph. [1] These are two separate systems.
| 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.
Water filters from the blood through the kidneys. Urine is also formed through the kidneys (helps remove wastes). When blood enters the kidney from the renal artery, it moves into the glomerulus, where filtration occurs. This is where water and dissolved particles are pulled out of the blood, resulting in a filtrate, which is then collected by the Bowman’s capsule. The nephron itself will then restore the vital nutrients and water back into the blood, while retaining the waste products the needs to eliminate, through the proximal and distal tubules.
Blood is taken to each of the four chambers of the heart by large blood vessels; vessels connecting the heart to the lungs are called pulmonary vessels. The aorta is connected to the left ventricle and carries oxygenated blood to all parts of the body (excluding the lungs, the vena cava is connected to the right atrium and brings deoxygenated blood back from the tissues of the body. The pulmonary artery is connected to the right ventricle and carries deoxygenated
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.
If there isn’t proper circulatory motion in the system sometimes the nodes can swell up and infect the tissues they are underneath. Usually the infection of lymph nodes can be prevented by proper exercise or maybe even a regulation with medicine of your plasma from your blood. Lymph vessels, called lacteals, are present in the lining of the gastrointestinal tract. While most other nutrients absorbed by the small intestine are passed on to the portal venous system to drain, via the portal vein, into the liver, for processing, fats
| | | Lesson 6 - The Cardio-Respiratory System DefinitionsThe cardio-respiratory system consists of the cardio vascular system (heart and blood vessels) together with respiratory system (lungs and air ways). These systems work to transport oxygen to the muscles and organs of the body and remove waste products including carbon dioxide. The HeartThe heart is a double pump. "Oxygen-poor" blood enters the heart from the vena cava to the right atrium, and flows down to the right ventricle. The first pump pumps "oxygen poor" blood to the lungs from the right ventricle of the heart via the pulmonary artery where it returns as "oxygen rich blood" via the pulmonary vein to the left atrium.
Blood and circulation The heart requires its own constant blood supply in order to keep beating and this is delivered through the coronary arteries. Genetic and lifestyle factors can lead to the coronary arteries becoming blocked, and an increased risk of heart disease. All living cells need to be supplied with materials like oxygen and glucose. They also need to get rid of waste materials like carbon dioxide. In single-celled organisms these materials are able to just diffuse in and out of the cell, however multicellular organisms e.g.
