ATI TEAS Cardiovascular System — Study
Guide and Practice Questions for TEAS Exam
cardiovascular system
Correct answer — -ALSO called the circulatory system -made up of the heart, blood vessels, the blood, and
lymphatic system. -waste removal, nutrient distribution, communication, protection.
heart
Correct 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
Correct 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
Correct answer — -chambers of the heart that collect and expel blood from the heart -2 of them; left and right
atrioventricular valves
Correct answer — valves that separate the atria and ventricles in the heart
tricuspid valve
Correct answer — separates the right atrium and right ventricle
mitral valve (bicuspid)
Correct answer — -ALSO called bicuspid -separates left atrium and left ventricle
types of blood vessels
Correct answer — 1. arteries 2. capillaries 3. veins
arteries
Correct answer — strong, elastic vessels adapted to the high pressure of blood as it leaves the heart
1
, arterioles
Correct answer — -smaller branches of arteries -supply blood to the capillaries
capillaries
Correct 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
Correct answer — -largest artery in the body! -the artery that carries blood pumped from the LEFT ventricle of the
heart into systemic circulation
diffusion
Correct answer — -process by which substances and gases are exchanged across a membrane; in this case,
blood and veins -substances tend to diffuse from areas of high concentration to areas of low concentration
venules
Correct answer — -blood returns to the heart from the capillaries via venules, which merge to form veins -vessels
that receive blood from capillaries
veins
Correct answer — -walls of veins are thinner than those of arteries b/c veins do not have to carry blood under high
pressure -contain valves to prevent the back flow of blood -vessels that return blood to the heart
inferior vena cava
Correct answer — -largest vein in the body! -brings deoxygenated blood back to the heart -runs from heart to
down body
pulmonary veins
Correct answer — -bring blood from the lungs to the heart -are among the few veins that carry oxygenated blood!
renal arteries
Correct answer — 2 branches of abdominal aorta that supply the kidneys
blood
