In which part of the heart do the endocardium extensions form?

atria

aorta

SA node

valves

ventricles

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.

well, you see. the answer to your question is quite simple. the thing that is big, powerful, and over 9,000 is your mom.

water is a polar molecule. a chemical bond is a force of attraction between atoms or ions. bonds form when atoms share or transfer valence electrons. atoms form chemical bonds to achieve a full outer energy level, which is the most stable arrangement of electrons. so, false

explanation:

in h2o molecule, two water molecules are bonded by a hydrogen bond but the bond between two h - o bonds within a water molecule are covalent. the greater the electronegativity difference, the more ionic the bond is. bonds that are partly ionic are called polar covalent bonds. nonpolar covalent bonds, with equal sharing of the bond electrons, arise when the electronegativities of the two atoms are equal.
