heart valves
The heart valves separate the atria and chambers of the heart as well as chambers and draining vessels from one another, thus ensuring blood flow in only one direction. A distinction is made between sail and pocket flaps. Defects in the valve closure occur
Parasympathetic nervous system

While the sympathetic nervous system is responsible for the active part, the parasympathetic nervous system takes care of the part under physical rest. One speaks
Pulse artery

Carotid artery
The carotid artery runs in pairs and supplies large parts of the head and neck with oxygenated blood. On the right it arises from the brachiocephalic trunk, on the left directly from the aortic arch. As it continues, it divides into the artery
