Following ovulation, what do the remains of the follicle form?
Primary follicle
Zygote
Corpus luteum
Oocyte
The Correct Answer is C
A. The primary follicle is an earlier stage in the development of the ovarian follicle, not the structure that forms after ovulation.
B. The zygote is the result of fertilization, formed when the sperm and egg unite, but it does not form from the follicle after ovulation.
C. The corpus luteum forms from the remains of the follicle after ovulation. It secretes progesterone to support early pregnancy or prepares to degenerate if pregnancy does not occur.
D. The oocyte is the egg cell itself, which is released during ovulation, but it is not the structure that forms from the follicle after ovulation.

Correct Answer is C
Explanation
A. As previously noted, the length of the thoracic cavity increases, not decreases, during the contraction of inspiratory muscles.
B. The diaphragm moves downward (not upward) when it contracts, allowing the lungs to expand.
C. The contraction of the diaphragm and external intercostals increases the diameter of the thoracic cavity, providing space for the lungs to expand and fill with air. This is the correct answer.
D. The chest cavity does not compress the lungs during inspiration; instead, it expands to accommodate the lungs as they fill with air.
Correct Answer is A
Explanation
A. During the expiratory phase of respiration, the diaphragm relaxes and moves upward, causing the chest cavity to decrease in size and forcing air out of the lungs. This is a key part of the breathing process.
B. Oxygen is not taken into the lungs during expiration. Instead, expiration is the process of expelling carbon dioxide from the lungs after oxygen has been absorbed during inspiration.
C. The diaphragm contracts during the inspiratory phase to increase the volume of the lungs and draw air in, not during expiration.
D. Oxygen is not released from the lungs during expiration; rather, carbon dioxide is expelled from the lungs as a waste product of metabolism.
