Types of Blood Vessels definitions Flashcards

Large, elastic vessels that transport oxygenated blood away from the heart to body tissues.

Small arteries that branch from larger arteries and lead directly into capillaries.

Smallest blood vessels with walls one cell thick, facilitating gas and nutrient exchange.

Small veins that collect blood from capillaries and merge into larger veins.

Vessels that carry deoxygenated blood back to the heart for reoxygenation.

System of blood vessels originating and returning to the heart, forming a closed loop.

Blood rich in oxygen, typically carried by arteries from the heart to tissues.

Blood low in oxygen, typically carried by veins back to the heart.

Pathway of blood movement, generally away from the heart in arteries and towards in veins.

Process occurring in capillaries where oxygen and carbon dioxide are exchanged with tissues.
