The lungs remain inflated because ___________.a. intrapleural pressure is exactly equal to atmospheric pressure b. intrapleural
kkurt [141]

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

Explanation:

The amount of genetic information contained in a normal human sperm cell (23 chromosomes) is one-half as much the information contained in a normal human body cell (46 chromosomes). Sperm cells are produced during meiosis, a specialized division process that <u>reduces the number of chromosomes in half</u>, generating haploid daughter cells.

Which characteristic of blood makes it especially effective in temperature regulation? Low specific heat capacity High specific
Dominik [7]

Answer:

High specific heat capacity.

Explanation:

Thermoregulation is the ability of an organism body to maintain it's internal temperature. It is an important aspect of homeostasis which is ability of an organism to maintain internal temperature not minding the surronding environment.

Blood have high specific heat capacity which help to maintain body temperature. Blood absorbs and distribute heat to the body, so as to maintain homeostasis. Blood vessels contracts when they react with outside environment.
