Accepted Answer

Small intestine

Question 3

Which vein is responsible for draining blood from the brain and returning it to the heart?

Accepted Answer

Internal jugular vein

Question 4

During a blood pressure measurement, which vessel's pressure is being assessed, and what is the standard formula for mean arterial pressure (MAP)?

Accepted Answer

Arteries; $$MAP = Diastolic + \frac{1}{3}(Systolic - Diastolic)$$

Question 5

Which lymphatic trunk drains lymph from the lower limbs and intestines, and into which duct does it empty?

Accepted Answer

Lumbar trunk; thoracic duct

Question 6

If the hepatic portal vein is blocked, which physiological process is most directly impaired?

Accepted Answer

Nutrient-rich blood flow from the digestive tract to the liver

Question 7

Which vessel is paired with the popliteal artery in terms of draining blood from the same region?

Accepted Answer

Popliteal vein

Question 8

A slide of a lymph node shows a capsule, cortex, and medullary cords. Which additional structure would confirm the presence of germinal centers?

Accepted Answer

Follicles

Question 9

Which of the following best describes the function of the spleen's white pulp?

Accepted Answer

Immune response and lymphocyte production

Question 10

A patient presents with swelling in the right arm. Which lymphatic vessel is most likely obstructed?

Accepted Answer

Right subclavian trunk

Question 11

Which artery supplies blood to the brain and is a branch of the aortic arch?

Accepted Answer

Brachiocephalic artery

Question 12

Which vessel is responsible for draining blood from the kidneys?

Accepted Answer

Renal vein

Question 13

Which of the following is a correct pairing of an artery and the body region it supplies?

Accepted Answer

External carotid artery; supplies the face and scalp

Question 14

Which structure is found in tonsils and is responsible for trapping pathogens?

Accepted Answer

Crypts

Question 15

A blockage in the anterior cerebral artery would most likely affect which function?

Accepted Answer

Motor control of the lower limbs

Question 16

Which vessel is responsible for carrying deoxygenated blood from the heart to the lungs?

Accepted Answer

Pulmonary artery

Question 17

Which of the following best describes the flow of blood through the hepatic portal circulation?

Accepted Answer

Blood from the digestive organs flows to the liver via the hepatic portal vein before entering systemic circulation.

Question 18

Which vessel is most likely to be palpated when taking a pulse at the wrist?

Accepted Answer

Radial artery

Question 19

Which lymphatic structure acts as a reservoir for lymph from the lower body before it enters the thoracic duct?

Accepted Answer

Cisterna chyli

Question 20

A patient has a blood pressure reading of 120/80 mmHg. Using the formula $$MAP = Diastolic + \frac{1}{3}(Systolic - Diastolic)$$, what is the mean arterial pressure?

Accepted Answer

$$MAP = 80 + \frac{1}{3}(120 - 80) = 80 + \frac{1}{3}(40) = 80 + 13.33 = 93.33$$ mmHg
