What the Heart Appearance Is Your heart is located near your lungs in the middle of your chest. It consists of four chambers that are separated by muscle and other cardiac tissue. Heart valves divide the chambers and ensure that blood continues to flow in the correct direction.
Learn more about and heart valves. Anatomy of the heart’s inside. This picture depicts the four chambers of the heart and the direction in which blood flows. Blue-purple blood, deficient in oxygen, moves into the heart and is pumped to the lungs. Then, with the assistance of the heart valves, oxygen-rich blood, depicted in red, is pumped to the rest of the body.
The two top chambers of the heart are known as the, while the two bottom chambers are known as the. From the body and lungs, blood travels to the atrium, and from the atrium to the ventricles. Blood is pumped from the heart to the lungs and other regions of the body through the ventricles. Endocardium is the thin inner lining of the heart chambers and the surface of the heart valves. Myocardium is the thick middle layer of muscle that enables the heart chambers to contract and relax in order to circulate blood throughout the body. Pericardium is the sac that surrounds the heart.
It is composed of thin layers of tissue and holds and protects the heart. A tiny quantity of fluid between the layers reduces the friction between the beating heart and the surrounding tissues. Certain disorders can alter the tissue of the heart. Occurs when the heart muscle enlarges, becomes thick, or becomes stiff.
As cardiomyopathy progresses, the heart gets weaker and less able to sustain a regular electrical rhythm and pump blood throughout the body. resides in one or more of the heart’s layers of tissue, such as the pericardium, myocardium, or endocardium. This can result in significant consequences, such as or an irregular heartbeat.
