Verified step by step guidance

Understand the function of each type of blood vessel: Arteries carry blood away from the heart, veins carry blood toward the heart, capillaries are sites of exchange between blood and tissues, and arterioles are small branches of arteries leading to capillaries.

Recall that arteries typically carry oxygen-rich blood from the heart to the rest of the body, except for the pulmonary arteries which carry oxygen-poor blood to the lungs.

Recognize that veins usually carry oxygen-poor blood from the body back to the heart, except for the pulmonary veins which carry oxygen-rich blood from the lungs to the heart.

Consider the role of capillaries, which are involved in the exchange of gases, nutrients, and waste products between blood and tissues, but do not specifically carry oxygen-rich or oxygen-poor blood.

Conclude that veins are the type of blood vessel that usually carries oxygen-poor blood, as they return deoxygenated blood from the body to the heart.
