Answer:
Valves of the heart do the endocardium extenstions.
Explanation:
Endocardium is the inner most layer of heart containing tissue that lines the heart chamber and the outer most layer of the heart is called epicardium.
The main function of this structure is to protect the valves and heart chamber.
The endocardium consists of endothelial cells that controls myocardial function.
The homeometric and heterometric regulation is separated by myocardial system.
The endocardium also functions as a blood heart barrier thus controlling the ionic composition withih which the cadiomyocytes bathe.

Explanation:
Membrane proteins are proteins that are either form part of or interact with cell membranes. Based on their interactions, membrane proteins can be categorized into integral proteins, which are a permanent part of a cell membrane, and peripheral proteins, which adhere temporarily to the cell membrane. Membrane proteins play many critical functions, for example, 1-they are involved in the passive and active transport of substances across cell membranes, 2-act as enzymes that catalyze chemical reactions, 3-act as receptors that bind specific molecules (such as hormones or neurotransmitters) in order to activate signaling cascades, 4-mediate communication between cells, 5-provide a mechanical link between the extracellular matrix and the cytoskeleton, etc.
it depends on the species DNA compared to another species to determine if the species are related or not. Like the human and the rhesus monkey they are closely related because all the genetic codes have the same DNA except one
