Introduction
Welcome to Shasa's Educational platform. This website was created by Shasa- Gay Clarke, in an effort to assist students to understand the heart and how it functions.
Did you know you that your heartbeats at least 100000 times per day?

Conclusion
What is the heart?
The heart is an organ that pumps blood throughout the body by the circulatory system. it supplies oxygen and nutrients to the tissues and removes carbon dioxide and other waste.
The human heart has four chambers: two upper (the atria) chambers and two lower chambers (the ventricles). The right atrium and the right ventricle together makeup, the "right heart", and the left atrium and left ventricle make up the "left heart".
How the heart function
The heart circulates blood through two pathways: the pulmonary circuit and the systemic circuit.
In the pulmonary circuit, deoxygenated blood leaves the right ventricle of the heart by the pulmonary artery and travels to the lungs, then returns as oxygenated blood to the left atrium of the heart by the pulmonary vein.
In the systemic circuit, oxygenated blood leaves the body by the left ventricle to the aorta, and from there enters the arteries and capillaries where it supplies the body's tissues with oxygen. Deoxygenated blood returns by veins to the venae cavae, re-entering the hearts right atrium.
