Chapter 8- Types of blood vessels

Question 1

Arterioles

Answer 1

Are small branches of arteries. One artery may branch into many arterioles that supply blood to the tissues

Question 2

Artery

Answer 2

Carry blood away from the heart towards a specific part of the body

Question 3

Blood pressure

Answer 3

The measurement of the force that blood pushes against the inside walls of the blood vessels

Question 4

Blood velocity

Answer 4

The rate of blood flow

Question 5

Blood vessels

Answer 5

Transport blood to and from the heart. Consists of arteries, arterioles, capillaries, venules, and veins

Question 6

Capillaries

Answer 6

A group of small blood vessels connecting an arteriole to a venule in the tissues; the sites of capillary-tissue fluid exchange that provides nutrients to cells and carries away waste products of cell metabolism

Question 7

Cross-sectional area

Answer 7

Refers to the area of the circular opening (lumen) that exists inside the vessel; total cross-sectional area of vessels is smallest in arteries and veins and much larger in the capillaries, due to a larger number of vessels, impacts blood velocity and blood pressure

Question 8

Veins

Answer 8

Are larger blood vessels that collect blood and return it to the heart

Question 9

Venules

Answer 9

Small veins that collect blood draining from capillary beds
