The pulmonary valve regulates the flow of blood from the heart to the lungs. Diseases can significantly affect its performance. What is the pulmonary valve? The term pulmonic comes from the Latin term pulmo for the lungs. Accordingly, the pulmonic valve is the one that regulates the flow of deoxygenated blood to the lungs. It … Pulmonary Valve: Structure, Function & Diseases
Clinical aspects of heart valves If the function of a heart valve is restricted, this is called heart valve vitium. Such a vitamin can be congenital or acquired. There are two types of functional limitations: Mild valve defects can go unnoticed, while more severe ones usually become symptomatic sooner or later. Common to all valve … Clinical aspects of heart valves | Heart valves
Synonym: Valvae cordis Definition The heart consists of four cavities, which are separated from each other and from the respective blood vessels by a total of four heart valves. This allows blood to flow in only one direction and only when it is appropriate within the scope of the heart action (systole or diastole). The … Heart valves
Introduction The heart plays a central role in the human cardiovascular system because it is the motor of the circulatory system. The blood from the body’s circulatory system first reaches the right half of the heart. From there the blood is pumped into the lungs, where it is supplied with oxygen. From the pulmonary circulation … Task of the heart
Tasks of the atria In the atria, the heart collects the blood from the preceding circulatory segments. Through the upper and lower vena cava, the blood from the body’s circulation reaches the right atrium. From there it is pumped through the tricuspid valve into the right ventricle. The atrium itself has hardly any pumping function. … Tasks of the atria | Task of the heart
Task of the heart valves The heart has four heart valves, whereby one differentiates between pocket and sail valves. The two sail valves separate the atria of the heart from the ventricles. The so-called tricuspid valve lies between the right atrium and the right ventricle, the mitral valve forms the border between the left atrium … Task of the heart valves | Task of the heart
Task of the pacemaker A pacemaker is needed when the heart is no longer able to beat regularly on its own. This can have various causes. For example, the sinus node, the heart‘s own pacemaker, no longer works reliably or there are problems in the conduction system. In both cases the pacemaker can take over … Task of the pacemaker | Task of the heart
