The correct answer is stabilising selection. This is selection that favours an average trait value. It is thought that this sort of selection is very common as traits among most animals do not appear to change drastically over time. Stabilising selection selects against the extreme traits, and leads to a decrease in genetic diversity by favouring the average phenotypes.
The pulmonary circulation conveys blood that is low in oxygen to the lungs before returning back to the left side of the heart.
<h3>The pulmonary circulation</h3>
The circulatory system is divided into two main parts namely:
- pulmonary circulation and
The pulmonary circulation involves the movement of blood between the lungs and the heart.
Blood from the systemic circulation returns to the right side of the heart where it is pumped through the pulmonary artery into the lungs to be oxygenated.
After oxygenation has taken place in the lungs, the blood returns to the left side of the heart through the pulmonary veins.
