The pericardium serves as protection for the heart, as it is a two layer liquid filled sac that surrounds the entire muscle. It protects the heart from infection and over-expansion when there is an increase in blood volume. It also serves as a container for the heart.
How do arteries differ from veins in their structure?
Arteries have thicker walls than veins do because there is a higher blood pressure in arteries than in veins, as the blood is being pumped from the heart to the body, and not vice versa.
What function does the auricle serve?
The auricle collects blood in a pouch before transferring it to the left or right ventricle, depending on the auricle(left or right).
What differences between the external structures of the atria and the ventricles do you observe?
Atria is smaller than the ventricles, and there are thicker walls in the ventricles. There is more fat near the atrium.

Why is the "anchoring" of the heart valves by the chordate tendinae and the papillary muscle important to heart function?
The anchoring of the heart valves by the chordate tendinae and the papillary muscle is important because it keeps the bicuspid valve and the tricuspid valve in place, so blood flow will remain in one direction.

What is the function of the semi-lunar valves?
The semi-lunar valves prevent incorrect blood flow within the heart.

If the valve disease occurs on the right side of the heart, it results in swelling in the feet and ankles. Why might this happen?
It may have an impact on the inferior vena cava, which sends blood to the bottom half of the body, which includes the feet and ankles.

If the valve disease occurs on the left side of the heart, what complications would you expect to see?
Blood flow between the lungs and the left atrium could be altered. The flow of oxygenated blood to the rest of the heart would be interrupted, and that could result in lack of muscle response in certain areas.

Describe how the left and right sides of the heart differ from each other.
The left side of the heart is in charge of oxygenated blood, while the right side takes care of the oxygen poor blood.
