CARDIOVASCULAR SYSTEMS
The heart structure is made of the heart and blood and responsible for carrying oxygen, nutrients, hormones, and cellular waste. The heart, the strongest muscle, has many anatomical terms associated with it like the aorta, vena cava, pulmonary veins, and the pulmonary trunk. Similarly as the picture above representing the different circulations; the pulmonary circulation loop and systematic circulation loop also involves the heart and lungs. Firstly, the pulmonary circulation transports deoxygenated blood from the right side of the heart to the lungs, where the blood picks up oxygen returning to the left side of the heart. Pumping chambers of the heart supporting the pulmonary circulation loop are the right atrium and right ventricle.
Secondly, the systemic circulation carries extremely high oxygenated blood from the left side of the heart to all of the tissues of the body (an exception to the heart and lungs). Systemic circulation removes wastes from body tissues returning deoxygenated blood to the right side of the heart. The left atrium and left ventricle of the heart are the pumping chambers for the systemic circulation loop.
To add, arteries are blood vessels carrying high amounts of oxygen away from the heart, only enough for the lungs. Pulmonary trunk and arteries of the pulmonary circulation loop carry deoxygenated blood from the heart to the lungs to be oxygenated. Arterioles are narrower arteries that branch off from the ends of arteries and carry blood to capillaries. Arterioles face much lower blood pressures than arteries due to their greater number, decreased blood volume, and distance from direct pressure from heart.
Capillaries connect to arterioles on one end and venules on the other. Capillaries carry blood very close to the cells of the tissues of the body in order to exchange gases, nutrients, and waste products. Veins are the large return vessels of the body and act as the blood return counterparts of arteries. Venules connect to veins instead of arteries and pick up blood from many capillaries and deposit it into larger veins for transport back to the heart.
