Answer:

The correct answer is option B- pressure within the alveoli.

Explanation:

Intrapulmonary pressure is the pressure within the lungs especially in the alveoli of the lungs so is also known as "intra-alveolar pressure".

This pressure helps in the breathing process as :

1. During inspiration - The thoracic cavity volume increases due to which the intra-pulmonary pressure becomes less than the atmospheric pressure which causes the lungs to inhale about 500 ml of air.

2. During expiration- the thoracic volume decreases which cause the intra-pulmonary pressure larger than atmospheric pressure which causes the lungs to exhale the air.

Thus, option B- pressure within the alveoli is the correct answer.

When corpus luteum degenerates,
Phantasy [73]

Answer:

The best answer to the question: When the corpus luteum degenerates:___, would be, E: All of the above.

Explanation:

The process of human female reproduction is a very complex one. But center in it is the corpus luteum, a structure that develops from a follicle in the ovaries and which will be responsible for producing estrogens and progesterones to maintain pregnany in case there is egg fertilization, or, the dismantling of everything by decaying and thus stopping the outpour of these  gonadal steroids. When fertilization occurs, the corpus luteum, by producing estrogen and progestorone, inhibits the further production of LH and FSH, and thus the entire process for a successful pregnancy takes place. But when this does not occur, LH and FSH increase again, progesterone, most especially, decreases, and as a result, the endometrium, which had been prepared for implantation, sloughs off. This is why the answer is E.
