Question 1

These are the large blood vessels that carry blood away from the heart.&#10;A) veins&#10;B) arterioles&#10;C) venules&#10;D) arteries

Accepted Answer

Because the primary function of the large arteries is to conduct blood from the heart to the arterioles, the large arteries are called conductance vessels.

Question 2

What do we call the path of blood from the right ventricle of the heart to the lungs and back to the left atrium?&#10;A) systemic circulation&#10;B) pulmonary circulation&#10;C) circulatory system&#10;D) arterial circulation

Accepted Answer

The pulmonary circulation carries blood from the right ventricle of the heart to the lungs and back to the left atrium of the heart

Question 3

The ________ are the smallest and most numerous of all the blood vessels. They connect the arterioles with the venules.&#10;A) veins&#10;B) capillaries&#10;C) capacitance vessels&#10;D) arteries

Accepted Answer

The capillaries are the smallest and most numerous of all the blood vessels. They connect the arterioles with the venules. Because the body has so many of them, a capillary is close to every cell in the body.

Question 4

The artery wall has three layers. Which of the following is not considered a part of the artery wall?&#10;A) tunica endothelium&#10;B) tunica intima&#10;C) tunica media&#10;D) tunica adventitia

Accepted Answer

With the exception of the capillaries, the blood vessels are composed of three layers (or tunics) of tissue: tunica intima, tunica media, and tunica adventitia.

Question 5

These vessels are called resistance vessels because the contraction and relaxation of the muscle changes vessel diameter, which alters resistance to the blood flow.&#10;A) artery&#10;B) vein&#10;C) arteriole&#10;D) capillary

Accepted Answer

By changing their diameter, the arterioles affect resistance to the flow of blood. A narrow (constricted) vessel offers an increased resistance to blood flow; a wider (dilated) vessel offers less resistance. Because of their effect on resistance, the arterioles are called resistance vessels.

Question 6

The ascending aorta arises from which chamber of the heart?&#10;A) right ventricle&#10;B) left ventricle&#10;C) right atrium&#10;D) left atrium

Accepted Answer

The ascending aorta arises from the left ventricle of the heart.

Question 7

The left and right subclavian arteries supply blood to which area of the body?&#10;A) the shoulders and upper arms&#10;B) the thoracic cavity&#10;C) the hips and upper legs&#10;D) the brain

Accepted Answer

Tthe subclavian artery supplies blood to the shoulder and arm.

Question 8

The veins from all parts of the body carry blood to these vessels for delivery to the heart.&#10;A) branches of the descending aorta&#10;B) venae cavae&#10;C) arteries&#10;D) the celiac trunk

Accepted Answer

The veins carry blood from all parts of the body to the venae cavae for delivery to the heart. The venae cavae are the main veins.

Question 9

Which of the following blood vessels are not associated with supplying blood to the liver?&#10;A) brachiocephalic veins&#10;B) the portal vein&#10;C) the hepatic veins&#10;D) the hepatic artery

Accepted Answer

Three groups of blood vessels are associated with hepatic circulation: the portal vein, the hepatic veins, and the hepatic artery.

Question 10

What is the normal heart rate per minute or normal pulse?&#10;A) 58 beats/minute&#10;B) 62 beats/minute&#10;C) 68 beats/minute&#10;D) 72 beats/minute

Accepted Answer

By feeling a person's pulse, you can determine the heart rate. A normal heart rate is about 72 beats/min.
