The acoustic stethoscope is used in human medicine to listen to and auscultate various body sounds. Typically, these are heart sounds, sounds in the lungs and bronchi during inhalation and exhalation, bowel sounds caused by peristalsis, and possibly flow sounds in certain veins (e.g., the carotid arteries). Listening is done non-invasively, and the stethoscope is … Stethoscope: Treatment, Effect & Risks
The inferior vena cava is also called the inferior vena cava. It opens into the right atrium of the heart along with the superior vena cava, the superior vena cava. The inferior vena cava transports deoxygenated blood from the periphery of the body back to the heart. The vein is formed by joining with the … Inferior Vena Cava: Structure, Function & Diseases
Systole in clinical parlance refers to the tightening and subsequent contraction phase of the two ventricles of the heart. During the contraction phase, the two leaflet valves through which blood flowed from the two atria into the ventricles are closed, and the two leaflet valves in the left and right ventricles open. Blood is pumped … Systole: Function, Tasks, Role & Diseases
Systolic blood pressure is the peak blood pressure in the arterial portion of the systemic circulation that results from contraction of the left ventricle and continues into the aorta and through its branches into the arteries when the aortic valve is open. Peak blood pressure depends on several fixed and variable factors, including cardiac output, … Systolic Blood Pressure: Function, Tasks, Role & Diseases
Central blood volume is the portion of blood volume located in the pulmonary circulation and the left side of the heart. It affects the central venous pressure and the filling of the left ventricle during the relaxation phase of the heart (diastole). What is central blood volume? Central blood volume is the portion of blood … Central Blood Volume: Function, Tasks, Role & Diseases
Aortic valve insufficiency refers to an insufficiency of the aortic valve in the left ventricle of the heart. Some of the aortic blood may flow back during the relaxation phase of the chamber, with significant long-term effects on the heart and overall cardiovascular system, depending on the severity. What is aortic valve regurgitation? Leakage of … Aortic Valve Regurgitation: Causes, Symptoms & Treatment
What is the aortic root? The aortic root is a small section of our main artery (aorta). The aorta starts at the heart and then moves through the chest and abdomen via an arch where it supplies blood to various organs. The aortic root is the first section of the ascending aorta, which is only … Aortic Root
What is the normal diameter of the aortic root There is no standard value for the diameter of the aortic root that can be used as a benchmark for all individuals. This is due to the fact that each person has a certain body size and body surface area which have an influence on the … What is the normal diameter of the aortic root | Aortic Root
Anatomy of the aortic valve The aortic valve is one of the four heart valves and is located between the main artery (aorta) and the left ventricle. The aortic valve is a pocket valve and usually consists of a total of 3 pocket valves. Sometimes, however, there are only two pocket valves. The pockets have … Aortic valve
