There are 4 valves in the heart. The first valve though which the blood passes is the tricuspid which is one of the atrioventriculars (between a ventricle and an atrium) and stops backflow of blood from the right ventricle tothe right atrium. The next valve is the pulmonary valve, one of the semilunars, which stops backflow form the pulmonary artery to the right ventricle. The third valve is the mitral or bicuspid which (the other atrioventricular) which stops backflow from the left ventricle to the left atrium. The last valve is the aortic valve (the other semilunar) which stops backflow from the aorta to the left ventricel.

What are artrioventricles?
Atrioventricular valves ar the valves in the heart that lie between the atria and the ventricles. These valves stop the the blood from flowing back (in the wtong direction) from the ventricles into the atria. There are two atrioventricular valves, on the right is the Tricuspis and on the left is the Bicuspid or Mitral valve.
Is the heart responsible for circulation?

What adrenergic neurotransmitter receptor plays a role in heart activity?

What critical role does the nodal system play in heart physiology?
Normal impulse conduction
What is the role of the heart in endocine system?
Heart produce two types of hormones: ANP and BNP (A and B type natriuretic peptide), they also limit fibrosis and hypertrophy. BNP can be used as drug in the treatment of acute heart failure.
What is the role of papillary muscle?
The papillary muscles are muscles located in the ventricles of the heart. The role of the papillary muscle is to prevent inversion or prolapse or the atrioventricular valves.
What is the role of the chordea tendineae?
The role of the chordae tendinae (or heart strings) hold the positions of the flaps from the valves (tricuspid and the bicuspid/mitral valve) they basically help with preventing the backward flow of blood. The tendinae are attached to the valves and the papillary muscles :)
