After traveling through the cecum, feces then travels through which of the following sections of the colon?

A. Mast cells do not function to connect the skin to muscles. This is the role of connective tissues such as tendons.

B. Mast cells do not cushion bony prominences. Adipose tissue and connective tissue help to provide cushioning.

C. Mast cells are involved in the inflammatory response. They release histamine and leukotrienes, which play a significant role in initiating inflammation, especially during allergic reactions and immune responses. This is the correct answer.

D. While mast cells are involved in immune responses, their main role is not to directly destroy pathogens. Other cells like macrophages and neutrophils are responsible for pathogen destruction.

A. Cardiac index is a measurement of cardiac output adjusted for body surface area. It provides a more individualized assessment of heart function, but it does not describe the amount of blood ejected during each contraction.

B. Cardiac output refers to the total amount of blood the heart pumps in one minute, which is the product of stroke volume and heart rate. However, it describes the overall volume pumped by the heart, not the blood ejected per contraction.

C. Stroke volume is the term used to describe the amount of blood ejected from the left ventricle during each contraction. It is a key indicator of cardiac function.

D. Ejection fraction is the percentage of blood in the left ventricle that is pumped out with each contraction, representing the efficiency of the heart. It is related to stroke volume but is not the same as the volume ejected per contraction.
