Valves - position, function.
Answers
Answer:
These valves are actual flaps that are located on each end of the two ventricles (lower chambers of the heart)The four heart valves include the following:
tricuspid valve: located between the right atrium and the right ventricle
pulmonary valve: located between the right ventricle and the pulmonary artery
mitral valve: located between the left atrium and the left ventricle
aortic valve: located between the left ventricle and the aorta
The valves keep blood from flowing backwards. In fact, valves are flaps (leaflets) that serve as one-way blood inlets entering the ventricle and one-way blood outlets leaving the ventricle.
