Cardiovascular and Lymphatic-Immune Systems Worksheet Cardiovascular System Label the parts of the organ or structure, and describe the structure and its function. NumberStructureCharacteristics Function 1Left ventricleIt is the thickest of all the chambers. After flowing into the left atrium and through the mitral valve, blood enters the left ventricle before it is pumped out through the aortic valve into the aortic arch and onward to the rest of the body.Pumps oxygenated blood to tissues all over the body.2ArteryA good way to remember this is the A in arteries and away. The arteries always take out blood from the heart.Most arteries carry oxygenated (oxygen-rich) blood from the heart to the rest of the body.3VeinVeins differ from HYPERLINK http// o Artery arteries in structure and function for example, arteries are more muscular than veins, veins contain valves.Most veins carry deoxygenated (containing less oxygen and more carbon dioxide and other wastes) blood from the body tissues to the heart, which then sends that blood through the pulmonary system to be oxygenated again. Blood Vessels Label the parts of the structure, and describe the structure and its function. NumberStructureCharacteristics Function 1Internal carotid arteryIt has many curvatures in different parts of its path. When it passes through the carotid canal and the side of the body of the sphenoid bone, it has double curvature and looks like the italic letter S.Enters the skull and supplies the anterior part of the brain (via cerebral branches), the eye and its appendages, and sends branches to the forehead and nose.2External carotid arteryFlows upward on the side of the head to branch into various structures in the neck, face, jaw, scalp, and base of the skull.The external carotid arteries supply oxygenated blood to the head.3Subclavian arteryDescends from the aortic arch and leads to the right arm.The subclavian artery supply blood to parts of the shoulder, neck and head. 4Superior vena cavaIs one of the two major paths into which the veins from all parts of the body (except from the lungs back to the heart) converge to lead to the right atrium of the heart.Brings de-oxygenated blood from the head, neck, arm and chest regions of the body to the right atrium.5Pulmonary veinHumans have four of these veins in total, two from each lung. There are two right pulmonary veins, known as the right superior and right inferior veins.Are responsible for carrying oxygenated blood from the lungs to the left atrium of the heart.6Brachial arteryIs the major blood vessel located in the upper arm, which it supplies with blood.It supplies the arm with oxygenated blood.7AortaIt is the largest artery in the body. The aorta begins at the top of the left ventricle, the hearts muscular pumping chamber.Is the artery that carries oxygenated blood from the left ventricle. Because the aorta can stretch (expand), the pressure of the blood leaving the heart is more slowly and regularly transferred to the arteries.8Renal arteryThere are two blood vessels leading off from the abdominal aorta, which is located in the abdominal section of the hearts major artery, and go to the kidneys.Is one of these two blood vessels. Where the kidney curves inwards in a concave shape, the hilum is found, which is an opening where the renal artery enters.9Radial arteryThe radial artery are found in the forearm, at the back of the wrist on the thumb side, and in the hand.It is the major artery that carries blood to the lower arm along the side by the thumb.10Lliac arteryIs the main trunk of the systemic arteries in the cardiovascular system.This system carries oxygenated blood from the heart to the other areas of the body and back.11Ulnar arteryBranches off the brachial artery below the bend of the elbow, at the cubital fossa. It runs the length of the forearm and ends at the superficial palmer arch, where it meets the radial artery.Like its radial counterpart, delivers...
