In CHAD layers of fatty material build up inside the coronary arteries. This reduces the blood flow to the heart muscle cells.
The cells do not get enough oxygen.
The rate of fatty material deposit in the arteries can be slowed down by drugs called statin.
CHD or coronary heart disease is a disease that caused by the narrowing of coronary artery. Since the artery become smaller, the blood flow decreased and the oxygen supplies is decreased too. The fat deposit should be slower with statin consumption.
It’s probably B (I’m guessing)
Answer:
Air moves into the lungs from atmosphere
Explanation:
As per the gas law, pressure of a gas is indirectly proportional to the volume of the gas. Thus, if volume increases pressure decreases.
Here, the volume of alveoli has increased due to which the pressure within the alveolar space reduces such that the atmospheric pressure outside alveoli becomes higher than the alveolar pressure within the alveoli. Due to this difference in pressure, the air gushes into the lungs.
