ATI THE CARDIOVASCULAR SYSTEM FINAL
PAPER 2026 FULL QUESTIONS WITH CORRECT
ANSWERS
◍ heart . Answer: -composed of cardiac muscle tissue
-4 muscular chambers of heart: right and left atria and the right and left
ventricles
-regulates blood flow through a double-loop system, pumping
oxygenated blood to body tissue and deoxygenated blood to the lungs
◍ atria . Answer: -2 of them; left and right
-chambers of the heart that receive blood returning to the heart from
other areas of the body
◍ ventricles . Answer: -chambers of the heart that collect and expel
blood from the heart

◍ atrioventricular valves . Answer: valves that separate the atria and
ventricles in the heart

, ◍ mitral valve (bicuspid) . Answer: -ALSO called bicuspid
-separates left atrium and left ventricle
◍ types of blood vessels . Answer: 1. arteries
2. capillaries
3. veins
◍ arteries . Answer: strong, elastic vessels adapted to the high pressure
of blood as it leaves the heart
◍ arterioles . Answer: -smaller branches of arteries
-supply blood to the capillaries
◍ capillaries . Answer: -smallest blood vessels
-consist of only a single layer of epithelial tissue, which allows
substances and gases to be exchanged b/t the blood and the cells of
tissues via diffusion
-receive blood from the arterioles and return it to the venules
◍ aorta . Answer: -largest artery in the body!
-the artery that carries blood pumped from the LEFT ventricle of the
