Where is chyme produced,?

A.

Pancreas

B.

Stomach

C.

Small Intestine

D.

Large Intestine

Answer and Explanation

The Correct Answer is B

A. Pancreas: pancreas secretes enzymes such as amylase (for carbohydrate digestion), lipase (for fat digestion), and proteases (such as trypsin and chymotrypsin for protein digestion). These enzymes are secreted into the small intestine to aid in the digestion of chyme.

B. Stomach: Chyme is a semi-fluid mixture of partially digested food and digestive juices formed in the stomach. The stomach’s muscular contractions mix food with gastric secretions, resulting in this thick paste that is then gradually released into the small intestine for further digestion.

C. Small Intestine: While the small intestine further processes chyme through digestion and absorption, it does not produce it.

D. Large Intestine: The large intestine primarily absorbs water and electrolytes from indigestible food matter and forms waste, but it does not produce chyme.

Correct Answer is D

Explanation

A. Vasa recta: This is a group of capillaries around the nephron loop (loop of Henle), not part of the distal convoluted tubule.

B. Pedicel: These are foot-like projections of podocytes in the glomerulus, not part of the distal convoluted tubule.

C. Bowman's capsule: This surrounds the glomerulus and is part of the filtration process, not the juxtaglomerular apparatus.

D. Macula densa: The macula densa is a group of cells located in the wall of the distal convoluted tubule that senses sodium concentration and regulates blood pressure and filtration rate.

Correct Answer is D

Explanation

A. Fully mature and leave the epididymis: The acrosome does not play a role in sperm maturation or their release from the epididymis.

B. Travel through the male reproductive ducts: Movement through the reproductive ducts relies on the sperm's flagellum and muscle contractions, not the acrosome.

C. Develop a full set of chromosomes: Chromosome development occurs during spermatogenesis and is unrelated to the acrosome.

D. Breach and fertilize the ovum: The acrosome contains enzymes that allow the sperm to penetrate the ovum during fertilization. Without an acrosome, the sperm would be unable to breach the egg’s outer layer.
