Isn’t it active transport????
Answer:
C
Explanation:
Greenhouse gases allow for sunlight, and the heat radiation to enter the atmosphere, and then prevent it from exiting the atmosphere. Known as the greenhouse effect.
This question has choices namely:
preload
afterload
contractility
cardiac reserve
The correct answer is preload. Preload is the filling capacity of the heart and it corresponds to the volume of the blood that fills the ventricles during a cycle. In this case, the left ventricle needs to accommodate the increased volume from the right heat therefore increasing the filling capacity therefore the preload.
Afterload is the pressure that the heart needs to overcome to pump the blood. In the right ventricle, the pressure is the pulmonary arteries wherein the right ventricle needs to contract and generate a pressure greater than the pulmonary arteries for the blood to move out the ventricle. Similarly, in the left ventricle, the source of pressure is the aorta and the left ventricle needs to contract and generate a pressure greater than the aorta and the systemic circulation for the blood to move out of the ventricle.
Contractility is the force of contraction of each ventricle in one cycle.
