Question 1

Blood leaving the right ventricle enters which blood vessel?

Accepted Answer

Blood leaving the right ventricle enters the pulmonary trunk, which divides into the left and right pulmonary arteries to carry deoxygenated blood to the lungs for oxygenation.

Question 2

Identify the deep femoral artery in this figure.

Accepted Answer

A

Question 3

The inferior mesenteric artery arises from which blood vessel?

Accepted Answer

The inferior mesenteric artery arises directly from the abdominal aorta.

Question 4

The external iliac artery continues into the hindlimb as the ________.

Accepted Answer

The external iliac artery continues into the hindlimb as the femoral artery.

Question 5

As the aorta extends posteriorly beyond the diaphragm, it is called the ________.

Accepted Answer

The portion of the aorta located in the abdomen is called the abdominal aorta. The thoracic aorta is the portion of the aorta located in the chest, and the aortic arch is the portion that curves and branches off into various arteries. Since the question specifies that the aorta has extended beyond the diaphragm (which separates the chest from the abdomen), the correct answer is the abdominal aorta.

Question 6

Which type of blood vessels carries blood away from the heart?

Accepted Answer

Arteries carry blood away from the heart.

Question 7

Identify the aortic arch in the figure.

Accepted Answer

The answer of Identify the aortic arch in the figure....

Question 8

The celiac trunk branches off the ________.

Accepted Answer

The celiac trunk branches off the abdominal aorta.

Question 9

Which artery carries blood to the gallbladder?

Accepted Answer

The cystic artery carries blood to the gallbladder.

Question 10

Which blood vessels supplies blood to the pericardium, mediastinum, and the diaphragm?

Accepted Answer

The internal mammary artery supplies blood to the pericardium, mediastinum, and the diaphragm.

Question 11

The celiac trunk divides into three branches. Which one of these vessels is NOT a branch of the celiac trunk?

Accepted Answer

The superior mesenteric artery is not a branch of the celiac trunk, but rather arises directly from the abdominal aorta just below the celiac trunk. The other three vessels (left gastric artery, splenic artery, and hepatic artery) are all branches of the celiac trunk.

Question 12

The fetal pulmonary trunk is attached to the fetal aorta via the ________.

Accepted Answer

The fetal pulmonary trunk is attached to the fetal aorta via the ductus arteriosus, which allows most of the blood from the pulmonary artery to bypass the lungs and flow directly into the aorta. After birth, this ductus normally closes and becomes the ligamentum arteriosum.

Question 13

As the axillary artery enters the forelimb, it becomes the ________.

Accepted Answer

The axillary artery continues as the brachial artery as it enters the forelimb, which supplies blood to the arm.

Question 14

The right subclavian artery and the left common carotid artery branch off from which vessel?

Accepted Answer

The right subclavian artery and the left common carotid artery both branch off from the brachiocephalic artery, which is the first branch of the aortic arch.

Question 15

Which blood vessel supplies blood to the deep muscles of the neck and shoulder and to the first two costal interspaces?

Accepted Answer

The costocervical artery supplies blood to the deep muscles of the neck and shoulder and to the first two costal interspaces. The long thoracic artery supplies blood to the serratus anterior muscle. The subscapular artery supplies blood to the subscapularis muscle. The intercostal artery supplies blood to the intercostal muscles. The ventral thoracic artery is not a vessel that exists in the human body.

Question 16

Which of the following arteries does NOT branch off from the brachial artery?

Accepted Answer

The axillary artery is a major artery that branches off from the subclavian artery, not the brachial artery. The other four arteries listed all branch off from the brachial artery.

Question 17

Identify the major arterial vessel which gives rise to all major arteries except those that supply the lungs.

Accepted Answer

The aorta is the major arterial vessel that gives rise to all major arteries except those that supply the lungs. The celiac trunk supplies the foregut, the ligamentum arteriosum is a remnant of the fetal circulation, the precava is a vein, and the pulmonary trunk supplies the lungs.

Question 18

Which artery carries blood from the abdominal aorta to the hindlimbs?

Accepted Answer

The external iliac artery carries blood from the abdominal aorta to the hindlimbs.

Question 19

List the blood vessels that a drop of blood will pass through as it leaves the abdominal aorta and moves distally towards the paw of the hindlimb:
1 Femoral artery
2 External iliac
3 Posterior tibial artery
4 Popliteal artery

Accepted Answer

The blood vessels that a drop of blood will pass through as it leaves the abdominal aorta and moves distally towards the paw of the hindlimb are External iliac artery, Femoral artery, Popliteal artery, and Posterior tibial artery. So, the correct sequence is 2, 1, 4, 3, which is option C.

Question 20

Which artery supplies blood to the brachium?

Accepted Answer

The axillary artery is the main artery that supplies blood to the brachium, or arm.
