Eddi Din [679]

Answer:

The human heart has it own nervous system, nodal system. It's made of nodes (that produces nerve impulses) and nerve fibers (running to all parts of the heart). Our nervous system can only increase or decreasing the nodes firing rates.

Starting with deoxygenated blood (oxygen poor blood), it travels from the superior and inferior vena cava into the right atrium, then into the right ventricle via the tricuspid value. There, it enters the pulmonary arteries via the pulmonic value. From there, it heads to the lungs and become oxygenated (rich in oxygen). It re-enters the left atrium of the heart via the pulmonary veins. There, it now travels to the left ventricle via the mitral valve and then into the aorta via the aortic value. From there it travels to the rest of the body supplying cells with oxygen and return back via the vena cava.

vovangra [49]

The perivascular feet of the <u>endothelial cells</u> help create a blood-brain barrier.

<h3>What are endothelial cells?</h3>

Endothelial cells can be defined as those type of cells found in the inside lining of blood vessels, lymph vessels, and the heart.

Interestingly, the major function of the edothelial cells is that they release substances that control vascular relaxation and contraction as well as enzymes that control blood clotting, immune function and platelet (a colorless substance in the blood) adhesion.

So therefore, the perivascular feet of the endothelial cells help create a blood-brain barrier.
