DENIUS [597]

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.

Why must informative speakers be careful not to overestimate what the audience knows about the topic? listeners can become lost
Ann [662]

Answer:

Listeners can become lost

Explanation:

Informative speakers need to judge their audience before they speak. They need to know some facts about their listeners, where do they come from, from which background socially and ethnically, and they may want to know something about their religion or interests. This way they can judge the level of the audience's knowledge about the subject they will speak upon.

If the informative speakers overestimate the listeners' knowledge on a particular subjects, the listeners will become frustrated because they won't understand what the speakers are telling them. They may consider themselves to stupid or not knowledgeable enough to listen to this speech. After trying to understand, they give up in the end and <em>can become lost</em>, not understanding the speaker and the topic he speaks upon.
