What are two functions of the arteries?
Arteries carry blood away from the heart. Pulmonary arteries transport blood that has a low oxygen content from the right ventricle to the lungs. Systemic arteries transport oxygenated blood from the left ventricle to the body tissues.
What are the two loops of the cardiovascular system?
There are 2 primary circulatory loops in the human body: the pulmonary circulation loop and the systemic circulation loop. Pulmonary circulation transports deoxygenated blood from the right side of the heart to the lungs, where the blood picks up oxygen and returns to the left side of the heart.

What do arteries do? They carry blood away from the heart towards the cells of the body. Almost all arteries carry oxygenated blood.
Which is the largest and the main artery in the circulatory system?
The largest artery is the aorta, which connects to the heart and picks up oxygenated blood from the left ventricle. The only artery that picks up deoxygenated blood is the pulmonary artery, which runs between the heart and lungs.
What is the main function of the circulatory system?
Arteries carry blood away from the heart and veins carry blood back to the heart. The circulatory system carries oxygen, nutrients, and hormones to cells, and removes waste products, like carbon dioxide.
What main arteries supply blood to the myocardium?
Coronary arteries supply blood to the heart muscle. Like all other tissues in the body, the heart muscle needs oxygen-rich blood to function.
What are the two arteries?
What are the different coronary arteries? The two main coronary arteries are the left and right coronary arteries.
What is circumflex artery?
The circumflex artery branches off the left coronary artery and encircles the heart muscle. This artery supplies blood to the lateral side and back of the heart.
What is the OM artery in the heart?
The obtuse marginal (OM) arteries sometimes referred to as lateral branches are branch coronary arteries that come off the circumflex artery. There can be one or more obtuse marginal arteries. It typically traverses along the left margin of heart towards the apex.
What is the name of the largest vein in the body?
The largest vein in the human body is the inferior vena cava, which carries deoxygenated blood from the lower half of the body back up to the heart.

Anatomical terminology In human anatomy, the axillary artery is a large blood vessel that conveys oxygenated blood to the lateral aspect of the thorax, the axilla (armpit) and the upper limb. Its origin is at the lateral margin of the first rib, before which it is called the subclavian artery.
Are there 2 femoral arteries?
Anatomical variation Distal to the origin of the profunda femoris artery, the femoral artery rarely divides into two trunks, which reunite near the adductor hiatus. Occasionally, the artery is replaced by the inferior gluteal artery, which accompanies the sciatic nerve as it travels towards the popliteal fossa.
