Answer:
Option C, Intrapleural pressure is less than intrapulmonary pressure
Explanation:
During inspiration, the air enters the lungs due to lower pressure in the intrapulmonary or intra-alveolar than the atmospheric pressure. During quite respiration, the intrapulmonary pressure reduces to a pressure that is 3 mm Hg lower than that of atmospheric pressure. During quiet expiration, the intrapulmonary pressure rises up to a pressure that is 3 mm Hg higher than that of atmospheric pressure. This leads to lack of air in the intrapleural space thereby producing intrapleural pressure which is lesser than that of intrapulmonary pressure.
This difference in pressure (i.e higher pressure with in the lungs than the atmosphere) causes lungs to remain attached to the chest wall and hence looks inflated.
Hence, option C is correct
The endocrine system is composed of the following:
1) hypothalamus
2) pituitary gland
3) thyroid and parathyroids
4) adrenal glands
5) pineal gland and gonads
6) pancreas
Pituitary gland is involved in gigantism. Pituitary gland produces the growth hormone. Excessive growth hormone released by the pituitary may result to gigantism.
The enlargement of the thyroid gland is called goiter. It is a symptom of hypherthyroidism, a condition wherein levels of thyroid hormones in the blood are highly excessive.
What happens to the ocean water as it moves from Antarctica to the equator is : ( B ) It becomes less dense and rises to the surface.
<h3>Concept conveyor belt </h3>
The conveyor belt is a system of oceans which transports water and propel deep current of water bodies across the globe based on the differences in water densities.
As the ocean water moves from the Antarctica to the equator the cold ocean water mixes with the warm ocean water at the equator, which makes the water less dense and rises to the surface.
Hence we can conclude that What happens to the ocean water as it moves from Antarctica to the equator is It becomes less dense and rises to the surface.
