Oxygenated and Deoxygenated Blood

The circulatory system consists of

arteries, arterioles, capillaries, venules, and veins, and the lymphatic system

What are the two major types of blood vessels

Arteries and veins

What blood vessel travels away from the heart and are full of oxygen and nutrients

arteries

What are the smalllest arteries?

arterioles

Why are arterioles important to the cardiovascular system?

They control systematic blood flow and determine total peripheral resistance

What constantly contracts (vasoconstriction) or relaxes (vasodilation) to adjust blood flow to the body’s current metabolic condition?

arterioles

What type of blood carry deoxygenated blood back to the heart to pick up oxygen so the cycle can repeat?

veins

What are the smallest veins?

venules

What is the exception to arteries carrying oxygenated blood and veins carrying deoxygenated blood?

pulmonary artery

The Pulmonary artery carries ______________ blood and waste products such as _________ from the right ventricle to the lungs.

deoxygenated, carbon dioxide

The blood picks up oxygen in the _________

capillaries

What are very thin, fragile blood vessels, located in the tissues of the body and play the important role of exchanging oxygen and nutrients or waste for the vessels to transport?

capillaries

___________ blood enters the capillaries through the aterioles, and exit the capillaries _____________ with waste products and gases through the venules.

oxygenated, deoxygenated
