After traveling through the cecum, feces then travels through which of the following sections of the colon?
Transverse
Descending
Sigmoid
Ascending
The Correct Answer is D
A. The transverse colon is where feces travels after the ascending colon, moving from right to left across the abdomen. Feces does not move directly from the cecum to the transverse colon.
B. The descending colon is the part of the colon that runs down the left side of the abdomen. Feces moves into this section after passing through the transverse colon, not directly after the cecum.
C. The sigmoid colon is the final section of the colon before the rectum. Feces travels here after the descending colon, not immediately after the cecum.
D. The ascending colon is the section of the colon that feces travels through immediately after the cecum. It moves upward on the right side of the abdomen before passing into the transverse colon.

Correct Answer is B
Explanation
A. While phagocytes move to areas of infection or damage, their primary role is not clumping together and adhering to tissues but rather engulfing and digesting foreign particles.
B. Phagocytes, such as neutrophils and macrophages, are white blood cells that ingest and digest foreign pathogens, dead cells, and debris in damaged tissues. This is their primary function in the immune response.
C. Releasing histamine is the function of mast cells, not phagocytes. Histamine is involved in initiating inflammation, but phagocytes are focused on clearing pathogens and debris.
