The left ventricle wall is thicker than the right because it pumps blood around the body while the right pumps blood to the lungs, located close to the heart. Cardiac muscle, like skeletal muscle, is comprised of sarcomeres, the basic, contractile units of muscle. When your heart beats, it makes a "lub-DUB" sound. The fibrous skeleton is composed primarily of collagen, a protein found in every type of connective tissue in the human body. It is located in the center of the cardiac skeleton. The outer layer, the fibrous pericardium, is comprised of dense connective tissue that protects the heart, anchors it to the surrounding walls, and prevents it from overfilling. The right atrium receives deoxygenated blood from systemic circulation and the left atrium receives oxygenated blood from pulmonary circulation. The circulatory system While the heart and lungs are the largest organs of the circulatory system, the blood vessels are the longest. Each valve has a set of flaps also called leaflets or cusps.
pulmonary valve. The heart has a total of four chambers: right atrium, right ventricle, left atrium These valves ensure that blood flows in only one direction, preventing backflow.

Heart is one of the major parts of our body. Right-hand side Deoxygenated blood from the body is carried to the heart in the vena cava.
The pulmonary artery carries deoxygenated blood from the right ventricle into the lungs for oxygenation.

One exists in the pulmonary artery on the right side and is called the pulmonary valve.
The right ventricle uses the pulmonary valve to help move blood into the The aortic valve closes quickly to prevent blood from flowing back into the left. aortic valve aorta. What valves prevent backflow into the right atrium, right ventricle, left the left ventricle has to transport blood throughout the whole body.
The left and right common iliac veins converge to form the inferior vena cava at its lowest point.
Deoxygenated blood enters the right atrium from the vena cava.
