The lungs add oxygen to the blood and remove carbon dioxide. Then the left side is responsible for accepting blood from the lungs and pumping it back out into the body. Think of it like a cycle where blood flows like this: From the body into the top right chamber (right atrium) -- down into the bottom right chamber (right ventricle) -- out to the lungs -- back to the top left chamber (left atrium) -- down to the bottom left chamber (left ventricle) -- then out to the body. The heart is innervated by the autonomic nervous system, but it also has its own system to generate electrical impulses that stimulate cardiac muscle to contract. These electrical impulses can be recorded in an ECG (electrocardiogram) and used to detect problems with the heart.
Blood capillaries converge to form venules and then veins. Lymph flows through lymph nodes. f. Describe the lymphatic system role with regard to lipids and lipid-soluble vitamins. The lymphatic vessels transport lipids and lipid-soluble vitamins A, D, E, and K absorbed by the gastrointestinal tract. 2.
From the lungs, blood drains into the left atrium and is then pumped into the left ventricle. The left ventricle then pumps this oxygen-rich blood out into the aorta which then distributes it to the rest of the body through other arteries. The heart is a hollow, muscular organ; its job is to pump blood through a network of blood vessels. The vessels form a circle, which starts at the heart, goes out through the body, then ends back at the heart again. The heart has two sides, the right and the left side.
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

And Inguinal lymph nodes are located in the groin area, these also may be superficial or deep lymph nodes. The major functions of lymph nodes are to remove foreign materials which are extracted from the lymph and deposited here. They store lymphocytes, type of white blood cell and releases them when necessary. There are two types of lymphocytes, T-cell and B-cell lymphocytes. T-cells destroy foreign substances directly or indirectly by releasing various substances.
The blood that the heart moves carries oxygen and nutrients throughout the body and transports carbon dioxide and other wastes to the lungs, kidneys, and liver for removal. The heart ensures its own oxygen supply through a set of coronary arteries and veins. The heart is also an endocrine organ that produces the hormones atrial natriuretic hormone (ANP) and B-type natriuretic peptide (BNP), which coordinate heart function with blood vessels and the kidneys. Internally, the heart is essentially hollow. It is divided vertically into two halves by a septum, and each side of the heart has two internal chambers – an atrium on top and a ventricle on the bottom.
Through the flow of blood in and out of arteries, and into the veins, and through the lymph nodes and into the lymph, the body is able to eliminate the products of cellular breakdown and bacterial invasion. Two very large areas are of significance in this system - the right lymphatic duct which drains lymph fluid from the upper right quarter of the body above the diaphragm and down the midline, and the thoracic duct, a structure roughly sixteen inches long located in the mediastinum of the pleural cavity which drains the rest of the body. It is through the actions of this system including the spleen, the thymus, lymph nodes and lymph ducts that our body is able to fight infection and to ward off invasion from foreign invaders. Lymph plays an important role in the immune system and in absorbing fats from the intestines. The lymphatic vessels are present wherever there are blood vessels and transport excess fluid to the end vessels without the assistance of any "pumping" action.
