Q: Which equation correctly represents Net Filtration Pressure (NFP) in the glomerulus?

NFP = $$\text{HP}_\text{gc} - (\text{OP}_\text{gc} + \text{HP}_\text{cs})$$

Question 1

Which of the following best describes the difference between the parietal and visceral peritoneum in the abdominal cavity?

Accepted Answer

The parietal peritoneum lines the body wall, while the visceral peritoneum covers the external surfaces of most digestive organs.

Question 2

Which of the following is NOT a function of the mesentery?

Accepted Answer

Increasing the surface area for absorption in the small intestine

Question 3

During swallowing, which structure prevents food from entering the respiratory tract?

Accepted Answer

Epiglottis

Question 4

Which of the following best describes the process of peristalsis?

Accepted Answer

Alternating waves of contraction and relaxation of smooth muscle that propel food along the GI tract

Question 5

A patient presents with jaundice and severe abdominal pain. Imaging reveals gallstones blocking the common bile duct. Which of the following is a likely consequence?

Accepted Answer

Impaired digestion and absorption of lipids due to reduced bile flow

Question 6

Which equation correctly represents Net Filtration Pressure (NFP) in the glomerulus?

Accepted Answer

NFP = $$	ext{HP}_	ext{gc} - (	ext{OP}_	ext{gc} + 	ext{HP}_	ext{cs})$$

Question 7

Which of the following cells in the gastric glands is responsible for secreting hydrochloric acid (HCl) and intrinsic factor?

Accepted Answer

Parietal cells

Question 8

Which modification of the small intestine mucosa is primarily responsible for increasing surface area for absorption?

Accepted Answer

Circular folds, villi, and microvilli

Question 9

Which of the following best describes the function of the enteric nervous system (ENS) in the GI tract?

Accepted Answer

It regulates local digestive activity independently of the central nervous system.

Question 10

Which of the following is TRUE regarding the juxtaglomerular complex (JGC) in the nephron?

Accepted Answer

The macula densa cells monitor sodium concentration in the distal convoluted tubule.

Question 11

Which of the following is a correct sequence for the passage of urine from the kidney to the outside of the body?

Accepted Answer

Renal cortex → renal medulla → renal pelvis → ureter → urinary bladder → urethra

Question 12

Which process is primarily responsible for the movement of nutrients from the lumen of the GI tract into the blood or lymph?

Accepted Answer

Absorption

Question 13

Which of the following best explains why most nutrient absorption requires active transport?

Accepted Answer

Active transport allows nutrients to move against their concentration gradient into enterocytes.

Question 14

Which of the following is a function of the bacterial microbiota in the large intestine?

Accepted Answer

Fermentation of indigestible carbohydrates and synthesis of certain vitamins

Question 15

Which equation correctly represents renal clearance ($$C) $$for a substance?

Accepted Answer

$$C = \frac{U 	imes V}{P}$$

Question 16

Which of the following is TRUE regarding the internal and external urethral sphincters?

Accepted Answer

The internal sphincter is composed of smooth muscle and is under involuntary control, while the external sphincter is skeletal muscle and under voluntary control.

Question 17

Which of the following best describes the role of bile salts in lipid digestion?

Accepted Answer

They emulsify fats, increasing the surface area for pancreatic lipase action.

Question 18

Which of the following is a correct description of the filtration membrane in the renal corpuscle?

Accepted Answer

It consists of fenestrated endothelium, basement membrane, and podocyte filtration slits, allowing passage of water, ions, and small molecules but preventing passage of blood cells and most proteins.

Question 19

Which of the following is TRUE regarding the phases of gastric secretion regulation?

Accepted Answer

The intestinal phase involves inhibition of gastric secretion as chyme enters the duodenum.
