Describe the two membranes covering the heart.

alex41 [277]

Answer: Fibrous pericardium and Serous Pericardium

Explanation:

The pericardium can be defined as the fibroserous sac( double layered) which covers the whole heart. The gap between two layers of serous pericardium is filled with serous fluid. This fluid protects the heart from external shocks.

Fibrous pericardium

This layer is the most superficial layer which consists of dense connective tissue. This layer of the heart protects it from over filling of blood, anchors the heart to the surrounding wall.

Serous pericardium

This layer provides lubrication to the heart by resisting the friction which occurs during the various type of heart function.

iren2701 [21]

Answer:

Macromolecules are transported from one space to another through a process of transcytosis or transcellular transport. It consists of a series of steps that will allow the mobility of macromolecules from one extracellular space to another, through the cellular menbrain, through a vesicle formation process. These vesicles maintain a certain load inside. The processes that are generated for the transcytosis process are those of endocytosis and exocytosis.
