Hello friends welcome to our channel, Eddiclases. Today's topic is CBS. Let's see what is the cardiovascular system. CBS means cardiovascular system, the system that alerts to the heart and blood vessels. Blood vessels are two types of heart and heart and heart. The oxygenated blood and brain carry the oxygenated blood. The exefson is pulmonary artery and pulmonary vein. This circulation provides oxygen and nutrient to the cell and helps to dispose the metabolic requestes. From heart, the t-oxygenated blood goes to the lungs for purification and from lung, the purified blood goes to the cells. This stem permits the blood nutrient and you will have strong to transport and circulate throughout the cell. So the system is also known as circulatory system. From inferior and superior vein, the blood goes to the heart and the impure blood by pulmonary artery goes to the lungs from lungs. After purification, the blood goes to the heart and again this blood goes to the cells. The heart located in front of the lungs and slightly went to the left side. Because of the pulse, the blood flowing in one direction. The atrium is the entry wall of the oxygenated blood and here the left atrium is for the pulmonary circulation and the right atrium is for the venous circulation. Here the left ventricle responsible for the pumping of oxygenated blood to the cells and the right ventricle pump the blood to the lungs. Here two types of hulks are present. The first one is tricuspid and second one is bicosphid or mitral valve. Tricomine porphyse of these valves are to separate the atrium and ventricle or prevent the backflow of blood. This barrier septum that prevents the mixing of deoxygenation and oxygenator blood by separating the atrium and ventricles of heart. The hulks are to separate the atrium and ventricles of heart. The first one is the luteus. The second one is the luteus. The second one is the luteus. The third one is the luteus. The third one is the luteus. The third one is the luteus. After completing purification the pure oxygenated blood through the pulmonary vein go to the left atrium and from left atrium. The mitral valve or bicosphruv valve the pure oxygenated blood from the left atrium to the left ventricle. From the left ventricle through the aorta the oxygenated blood go to the go throughout all the body cells to circulate the nutrients and blood.
