A group of students is reviewing information about the locations of various organs within the abdomen. The students demonstrate understanding of the material when they identify which organ as being found in the left upper quadrant

The given question is incomplete as it does not have the options which are:

a) Gallbladder

b) liver

c) spleen

d) head of pancreas

C) spleen

Explanation:

To study the organs present in the body, the abdomen region of the human body is divided into the four quadrants in which left upper quadrant is one of the quadrants.

The organs which fall under the left upper quadrant are the spleen, the left kidney, the portions of the stomach, the colon and the pancreas. The spleen covers the large portion of the left upper quadrant.

The spleen is a fist-shaped organ which is considered the secondary lymphoid organ that provides the site for lymphocyte cells and interaction with the pathogen.

Thus, Option-C is correct.
