Question 1

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

Accepted Answer

The external iliac artery continues down into the hindlimb as the femoral artery, which supplies blood to the thigh and leg muscles.

Question 2

The intercostal veins drain blood from the intercostal muscles into the ________ vein.

Accepted Answer

The azygous vein is responsible for draining the intercostal veins, which carry blood from the intercostal muscles. The axillary vein drains the upper limb and thoracic wall, while the subscapular vein drains the posterior shoulder region. The internal jugular vein drains blood from the head and neck.

Question 3

The radial vein is located on the ________ side of the forelimb.

Accepted Answer

The radial vein is located on the lateral side of the forelimb, corresponding to the thumb side of the hand or the outer side of the forearm.

Question 4

The medial and lateral branches of the popliteal vein drain blood from the ________.

Accepted Answer

The popliteal vein drains blood from the foot and calf region, not from the thigh, anterior knee, or hip.

Question 5

In humans, the posterior vena cava is called the ________.

Accepted Answer

The inferior vena cava is the large vein that carries deoxygenated blood from the lower half of the body to the right atrium of the heart. The superior vena cava carries deoxygenated blood from the upper half of the body to the right atrium of the heart, but it is not synonymous with the posterior vena cava. The pulmonary vein, on the other hand, carries oxygenated blood from the lungs to the left atrium of the heart. The jugular vein is a vein that carries deoxygenated blood from the head and neck region to the superior vena cava.

Question 6

Identify the external iliac vein in the following figure.

Accepted Answer

The external iliac vein is labeled as "EIV" and can be seen passing through the inguinal ligament into the pelvis. It is indicated by the arrow pointing to B.

Question 7

The celiac trunk divides into two main branches, the gastrosplenic artery and the ________ artery.

Accepted Answer

The celiac trunk divides into three main branches: the left gastric artery, the splenic artery, and the common hepatic artery. The common hepatic artery further divides into two branches, the proper hepatic artery and the gastroduodenal artery. The gastroduodenal artery then gives off the right gastroepiploic artery and the superior pancreaticoduodenal artery. The correct answer choice is D, as the gastrohepatic artery is not a recognized branch of the celiac trunk.

Question 8

List the blood vessels that a drop of blood will pass through as it leaves the head and travels toward the heart: 1. External jugular vein
2) Anterior vena cava
3) Subclavian vein
4) Brachiocephalic vein

Accepted Answer

Blood leaving the head first enters the external jugular vein, then flows into the subclavian vein, followed by the brachiocephalic vein, and finally into the anterior vena cava (more commonly known as the superior vena cava) before reaching the heart.

Question 9

The cephalic vein drains into the external jugular vein via the ________ vein.

Accepted Answer

The cephalic vein runs along the lateral aspect of the upper limb and drains into the axillary vein, which then becomes the subclavian vein. However, in some individuals, the cephalic vein can also drain into the external jugular vein via the transverse scapular vein. The brachial vein, ulnar vein, and radial vein are not directly involved in the drainage of the cephalic vein.

Question 10

List the veins that a drop of blood will pass through as it leaves the foot and returns to the heart: 1. Saphenous vein
2) Popliteal vein
3) External iliac vein
4) Femoral vein

Accepted Answer

Blood returning from the foot first enters the saphenous vein, then moves through the popliteal vein in the knee area, followed by the femoral vein in the thigh, and finally into the external iliac vein before reaching the heart.

Question 11

Identify the deep femoral artery in the following figure.

Question 12

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 13

Identify the saphenous vein in the following figure.

Accepted Answer

The answer of Identify the saphenous vein in the following...

Question 14

Identify the right cephalic vein in the following figure.

Accepted Answer

The cephalic vein is the large, visible vein running along the lateral aspect of the arm. In the given figure, the vein labeled as B is the cephalic vein. It runs along the outer aspect of the arm and can be easily seen in this position. Vein A is the basilic vein, which runs along the medial aspect of the arm, and veins C and D appear to be smaller branches off the cephalic vein.

Question 15

Which vessel carries oxygenated blood from the lung to the left atrium of the heart?

Accepted Answer

The pulmonary vein carries oxygenated blood from the lungs to the left atrium of the heart. Both the posterior and anterior vena cava carry deoxygenated blood into the right atrium of the heart, and the pulmonary artery carries deoxygenated blood from the heart to the lungs.

Question 16

The radial and ulnar veins drain into the ________ vein.

Accepted Answer

The radial and ulnar veins merge to form the brachial vein, which is located in the arm.

Question 17

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

Accepted Answer

As the aorta extends posteriorly beyond the diaphragm, it enters the abdominal cavity and is called the abdominal aorta. The aortic arch is located in the thoracic cavity and the thoracic aorta is the portion of the aorta that passes through the chest.

Question 18

Which of the following vessels does NOT drain into the axillary vein?

Accepted Answer

The internal thoracic vein drains into the brachiocephalic vein, not the axillary vein.

Question 19

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

Accepted Answer

The correct sequence for blood flow from the abdominal aorta to the paw of the hindlimb is: external iliac artery, femoral artery, popliteal artery, and then posterior tibial artery.

Question 20

Like humans, pigs have a common iliac artery that gives rise to the external and internal iliac arteries.
