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.

Explanation
A. Dehydration does not directly stimulate the production of erythrocytes. While dehydration can affect blood volume and viscosity, it is not a primary factor in erythropoiesis (the production of red blood cells).
B. Hypoxia (low oxygen levels) stimulates the production of erythropoietin, a hormone produced by the kidneys that promotes the formation of new erythrocytes in the bone marrow. This response helps improve oxygen delivery to tissues.
C. Inflammation triggers the immune response and can affect various blood cell types, but it does not directly stimulate erythropoiesis.
D. Infection can affect blood cell counts, but it is not a direct stimulus for the production of erythrocytes. The body may produce white blood cells as part of the immune response, but not red blood cells specifically.
