Some animals, but not humans, have an organ called a gizzard located near the top of their digestive tract. This organ is small, can contain small rocks, and has thick, muscular walls. Based on this physical description, which of the following is most likely the function of this organ?
Answer (2)
The gizzard is used for the preparation of digestion. The food is ground by the action of the muscular walls and also the gravel inside the gizzard.
The gizzard is primarily responsible for grinding food in some animals, particularly birds, using muscular walls and sometimes small rocks. This function is essential for aiding digestion by breaking down food into smaller pieces. Therefore, the correct choice is A. Grinding food with the help of small rocks.
