The inner layer of the serosal pericardium is a thin, transparent layer of simple squamous epithelium called the "visceral pericardium."
<h3>What is serosal pericardium?</h3>
A fibrous pericardium (parietal covering), which would be mirrored around the roots of the main veins to cover the whole surface of the heart, is lined by a layer of serosa called the serous pericardium (visceral layer).
Some key features of serosal pericardium are-
- There might be a little hole between the parietal & visceral layers that a small quantity of fluid might fill.
- The epicardium is the region of a visceral layer which surrounds the heart but not the major vessels.
- There are two sinuses formed by the serous pericardium as it reflects off different cardiac structures: the transverse sinus as well as the oblique sinus.
- A cul-de-sac formed by two left pulmonary circulation on one side and also the two pulmonary artery veins on the other, the oblique sinus extends superiorly from of the inferior vena cava.
- In between four pulmonary veins, its posterior wall of a left atrium forms its anterior wall. The left atrium has room to expand thanks to the oblique sinus.
- The visceral serosal pericardium is reflected from the posterior portions of the pulmonary and aortic veins onto the superior surface of the atrium to produce the transverse sinus, which is open at both ends.

Answer:
It is important because it keeps the other animals in check.
Explanation:
They keep the animals in check so there isn't an overpopulation of a certain animal.
Let's take sea otters for an example, the sea otters keep the sea urchins in check so they don't eat all the kelp. When there was a massive decrease in sea otters due to orcas eating them, the kelp was disappearing and the sea urchins were growing in population.
