Accepted Answer

The medial and lateral branches of the popliteal vein drain blood from the foot and calf region.

Question 2

Accepted Answer

The answer of Identify the deep popliteal artery in the...

Question 3

Which blood vessel drains blood from the abdomen, pelvis, and hindlimbs?

Accepted Answer

The postcava, also known as the inferior vena cava, is the largest vein in the body and drains blood from the lower half of the body, including the abdomen, pelvis, and hindlimbs. The precava, or superior vena cava, drains blood from the upper half of the body. The internal jugular vein drains blood from the head and neck, while the axillary vein drains blood from the arm.

Question 4

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

Accepted Answer

The external iliac artery turns into the femoral artery in the hindlimb, which is responsible for supplying blood to the lower leg and foot. The popliteal artery is a branch of the femoral artery that terminates at the knee joint. The anterior and posterior tibial arteries are branches of the popliteal artery and supply blood to the anterior and posterior compartments of the lower leg, respectively.

Question 5

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

Accepted Answer

The external iliac artery arises from the abdominal aorta just below the level of the umbilicus and carries blood to the hindlimbs. The internal iliac artery supplies the pelvic organs and the medial thigh. The iliolumbar artery supplies the lumbar vertebrae, muscles of the back and the spinal cord. The left colic artery supplies the descending colon.

Question 6

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

Question 7

Identify the deep femoral artery in this figure.

Accepted Answer

The answer of Identify the deep femoral artery in this...

Question 8

Which artery carries blood to the gallbladder?

Accepted Answer

The cystic artery is responsible for supplying blood to the gallbladder.

Question 9

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

Accepted Answer

Pulmonary veins carry oxygenated blood from the lungs to the left atrium of the heart. The other options (postcava, pulmonary artery, and precava) carry deoxygenated blood.

Question 10

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

Accepted Answer

The cephalic vein travels through the shoulder region and then curves back towards the anterior forearm, where it drains into the axillary vein. Before the axillary vein, it joins the transverse scapular vein to form the cephalic arch. The cephalic arch then continues as the cephalic vein and drains into the external jugular vein via the communicating branch known as the anterior jugular vein. The brachial, ulnar, and radial veins do not play a role in the direct drainage of the cephalic vein.

Question 11

In humans, the postcava is called the ________.

Accepted Answer

The postcava in humans is equivalent to the inferior vena cava, which is the large vein that returns deoxygenated blood from the lower body to the heart. The superior vena cava, on the other hand, returns blood from the upper body to the heart. The pulmonary vein carries oxygenated blood from the lungs to the heart, and the jugular vein drains blood from the head and neck.

Question 12

Which vein drains the small intestines, large intestines, and the pancreas?

Accepted Answer

The superior mesenteric vein drains the small intestines, large intestines, and the pancreas. The other veins listed, lumbar vein, gastrosplenic vein, and caudal vein, do not specifically drain these organs.

Question 13

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

Accepted Answer

The correct sequence for a drop of blood leaving the head and traveling towards the heart is through the external jugular vein, then into the subclavian vein, followed by the brachiocephalic vein, and finally into the precava (superior vena cava). This path reflects the typical venous drainage pattern from the head to the heart.

Question 14

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. The other veins listed typically drain into the axillary vein or are associated with the region that drains into the axillary vein.

Question 15

Which of the following veins does NOT drain into the hepatic portal vein?

Accepted Answer

The inferior phrenic vein drains into the inferior vena cava, not the hepatic portal vein. The other options all drain into the hepatic portal vein.

Question 16

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 17

The inferior mesenteric artery arises from which blood vessel?

Accepted Answer

The inferior mesenteric artery arises from the abdominal aorta, specifically from the left side of the aorta about 3-4 cm above its bifurcation into the common iliac arteries.

Question 18

The radial vein 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 19

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 then dumps into the superior vena cava.

Question 20

Which vein drains the tail and empties into the origin of the postcava?

Accepted Answer

The caudal vein drains the tail and empties into the origin of the postcava, also known as the caudal vena cava. The external and internal iliac veins drain the pelvic region and lower limb, respectively. The hepatic portal vein carries blood from the digestive system to the liver.
