What is the structure of the human heart?
your heart has two sides, a left side and a right side, they are separated through a thin muscular wall known as the Septum. Both, the left and right side of your heart have an upper chamber and a lower chamber.
The upper chambers are known as the left atrium and the right atrium.
The lower chambers are known as the left ventricle and the right ventricle.
The right atrium receives two large veins, the superior vane cava and the inferior vane cava. The superior vana cava brings deoxygenated blood from the head and upper region of the body. The inferior vana cava brings the deoxygenated blood from the lower region of the body. While The left atrium receives oxygenated blood from lungs via pulmonary veins. The left ventricle is thicker than the right ventricle because it has to push blood to all parts of the body at much higher pressure.
