Question

List the five blood vessels types and what they do.

Answer 1

Arteries

Arteries are elastic vessels that transport blood away from the heart. Pulmonary arteries carry blood from the heart to the lungs where oxygen is picked up by red blood cells. Systemic arteries deliver blood to the rest of the body.

Veins

Veins are elastic vessels that transport blood to the heart. Veins can be categorized into four main types: pulmonary, systemic, superficial, and deep veins.

Capillaries

Capillaries are extremely small vessels located within the tissues of the body that transport blood from the arteries to the veins. Fluid and gas exchange between capillaries and body tissues takes place at capillary beds.

Sinusoids

Sinusoids are extremely small vessels located within the liver, spleen, and bone marrow.

Arterioles
