Three Semilunar Valves
This causes systemic body circulation. To compare the two, both each have three semi-lunar cusps, which curve outward and into the opening of the receiving blood vessel. What separates the semilunar valves from the atrioventricular (AV) valves is that the semilunar valves contain no presence of papillary muscles or chordae tendineae. This is because pressure within the heart falls in this area, thereby forcing the semilunar valves to close on their own.
The hearts is a prime member of the circulatory system: the system that circulates blood and lymph through the body. The circulatory system consists of not only the heart, but the blood and a series of blood vessels. To add on, the heart also works in conjunction with the respiratory system, …show more content…
Since the heart is the body’s life sustaining organ, blood must be pumped and delivered constantly, which means the heart must never end the process. This process begins on the right side of the heart, when blood enters through the superior and inferior vena cava. These two deposit the oxygen deprived blood taken from the body into the right atrium. The right atrium begins contracting, which causes the blood delivered there to travel to the right ventricle through the tricuspid valve. Once the right ventricle fills with blood, the tricuspid valve shuts to prevent more blood flow into it. This also prevents the blood from back flowing into the right atrium. As the right ventricle contracts, the blood travels through the pulmonic valve and leaves the heart. Through the valve, the blood travels to the pulmonary artery and into the lungs, which is where the blood will be oxygenated. Once filled with oxygen, the blood travels through the pulmonary veins and goes into the left atrium. Once the oxygen filled blood is deposited into the left atrium, it begins to contract, which ultimately causes it to move into the left ventricle by utilizing the mitral valve. When the left ventricle is full with blood, just like the right side of the heart, the mitral valve shuts tight, preventing back flow of blood. Finally, the left ventricle contracts and the blood leaves through the aortic valve and out of the heart, where the blood is deposited throughout the
