Answer:
Arteries: These 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: These are also elastic vessels but they transport blood to the heart. The four types of veins are pulmonary, systemic, superficial, and deep veins.
Capillaries: These 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: These narrow vessels are located within the liver, spleen, and bone marrow. Like capillaries, they deliver blood from larger arteries to veins. Unlike capillaries, sinusoids are permeable and leaky to allow for quick nutrient absorption.
