S.1.3 Flashcards
functions of circulatory system
movement of blood which permits nutrient distribution, waste removal, and protection
components of cardiovascular system
heart, blood vessels, and blood
myocardium
muscle tissue
pericardium
sac enclosing the heart
interatrial septum
separates the right and left artia
inter-ventricular septum
separates the right and left ventricles
atrioventricular valves
tricuspid (right) and mitral (left)
semilunar valves
pulmonary (right) and aortic (left)
pulmonary valve
guides blood from the right ventricle to the pulmonary trunk to be transferred to the lungs
aortic valve
guides blood from the left ventricle to the aorta to be transferred to the blood vessels
pulmonary circulation
right side of the heart pumps deoxygenated blood from the heart towards the lungs
systemic circulation
receives oxygenated blood from the lungs and pumps it towards the rest of the body parts
arteries
carry blood away from the heart with thick layer of smooth muscle
capillaries
microscopic blood vessels where exchange of gases and nutrients occurs between alveoli and capillary beds
veins
carry blood towards the heart with one-way valves
