PHYSIOLOGY OF CARDIAC SYSTEM | KTU BIOMEDICAL ENGINEERING | MODULE 2 || LECT 8

Hi all, today we are going to start with the 2nd module. In the 2nd module, we are going to discuss about heart and cardiovascular system, electro-conditioning system of heart, electro-cardiography ECG, ECG lead configuration, ECG recording system, Eindhoven triangle and ECG signal analysis. Then we are going to discuss about measurement of blood pressure, indirect and relative measurement of blood pressure, and measurement of blood flow. These are the 3 modules we are going to cover in this module. Today, we are going to discuss about physiology of cardiac system. This is the structure of heart. Heart is a two-chambered pump. It has left and right side. Heart is a two-chambered pump with two sides. Upper chamber is called atria or atrium. Lower chamber is called ventricle. In the upper chamber of the heart, there is a collection process. Input is always through the upper chamber. In the lower chamber, output is through the lower chamber. This is the input arrow. Output is through the lower chamber. Heart has 4 valves. 1. Tricapsid valve 2. Mitral valve or biceps valve 3. Pulmonary valve 4. Aortic valve Heart has 4 valves. We will discuss about the details later. Heart has 4 valves. Heart has deoxygenated blood on the right side. Heart has pure blood on the left side. Heart has deoxygenated blood on the right side. Heart has pure blood on the left side. This is the function of inferior vena cava and superior vena cava. What is inferior vena cava and what is superior vena cava? Superior vena cava is the blood from the upper portion of the body. Inferior vena cava is the blood from the lower portion of the body. Inferior vena cava is the blood from the right atrium. Inferior vena cava is the blood from the right atrium to the right ventricle. Inferior vena cava is the blood from the left atrium to the right ventricle. Inferior vena cava is the blood from the pulmonary valve to the pulmonary artery. Inferior vena cava is the blood from the right atrium to the right ventricle. Inferior vena cava is the blood from the pulmonary valve to the pulmonary artery. Inferior vena cava is the blood from the pulmonary artery to the lungs. Inferior vena cava is the blood from the left atrium to the right ventricle. Inferior vena cava is the blood from the pulmonary artery to the left ventricle.
