Human Cardiovascular Anatomy and Physiology Quiz

Arteries carry oxygenated blood away from the heart.

The atria primarily receive blood from the body.

Hypertension is the medical term for high blood pressure.

Veins carry deoxygenated blood from the body back to the heart.

The left ventricle pumps oxygenated blood to the systemic circulation.

Arrhythmia is the medical term for an irregular heart rhythm.

The mitral valve separates the left atrium and left ventricle.

Cardiac output refers to the volume of blood pumped by the heart in one minute.

Systole is the contraction phase of the cardiac cycle.

Platelets are responsible for clotting and wound healing.

Adrenaline (Epinephrine) is released by the adrenal glands during the 'fight or flight' response, increasing heart rate and blood pressure.

Capillaries are the smallest blood vessels that connect arteries and veins, where exchange with tissues occurs.

Capillaries are responsible for exchanging nutrients and gases with tissues.

The atria are the upper chambers of the heart.

The SA node conducts electrical impulses in the heart.

During diastole, the heart relaxes and fills with blood.

Elevated cholesterol levels can contribute to atherosclerosis.
