Answer:
As a result of skeletal muscle contraction in physical exercise, the venous return - amount of blood that goes to the heart - is greater, so preload would be increased, which would result in a larger cardiac output.
Explanation:
Preload is a term associated with heart function, which consists of the amount of blood that reaches the ventricles from venous circulation.
This preload is able to occupy a space and stretch the walls of the ventricle and determine the amount of blood that will be pumped during ventricular contraction (systole).
In terms of cardiovascular function, preload depends on:
- <em>Final Diastolic Pressure of the Left Ventricle.
</em>
- <em>Final Diastolic Radius of the Left Ventricle.
</em>
- <em>Thickness of the ventricle.
</em>
- <em>Central venous pressure
</em>
- <em>The speed of venous return.
</em>
A consequence of the increased volume of blood in the ventricle -due to a higher preload- is the increase in cardiac output.

Answer: D) alpha: catabolism
Explanation:
Glycogen is the storage form of carbohydrates in animals. The major sites of storage are liver and muscle.
Glucagon is a polypeptide hormone, it is secreted by the alpha cells of the pancreas. Low blood glucose causes glucagon secretion. When blood glucose level falls, liver glycogen is broken and help to maintain blood glucose level.
Glucagon stimulates the enzyme glycogen phospholylase which breaks down glycogen into glucose units.
