Your heart has to work hard to pump more blood during exercise for each contraction, accounting for the increase in the systolic blood pressure. Diastolic pressure tends to not change at all or change slightly. The reason for this is that since the blood flow is increased during exercise, our arteries dilate, making the diastolic pressure stay the <span>same, or decrease slightly.</span>

Answer:
The correct answer would be D.Alveolar sacs are surrounded by thin capillaries where gases can be exchanged.
Alveoli are tiny sacs which form the site of gas exchange in the lungs.
The features of alveoli which help in gas exchange are:
- They increase the surface area in the lungs thus, more space is available for gas exchange.
- They have very thin walls, as thin as the thickness of a single cell only.
- They are surrounded by a bunch of thin capillaries which exchange gases with alveoli.
