The heart does not have doors, but it does have valves that could be thought of as doors. They consist of the semilunar valves (the pulmonary semilunar valve and the aortic semilunar valve). The other two are the atrioventricularvalves (tricuspid and bicuspid valves).
The four valves in the heart are: * the two semi-lunar valves - one at the stem of the aorta, the other is found at the trunk of the pulmonary artery. * The tricuspid valve is on the right-hand side of the heart. * The bicuspid valve is on the left side of the heart.
Heart valves control the flow of blood into, out of, and within the chambers of the heart. The main function is to let blood flow in one direction only, ensuring that blood does not flow backwards.
Well the heart is based on 4 chambers you have 2 upper ventricals and 2 lower ventricles the ventricles each have 2 little doors that open and close. the top right ventricle will suck in the blood and the bottom 2 will transfer it to the left top ventricle which than pushes the blood out into the blood stream again in average healty heart will beat 70-75 beats per minute. Children have a higher rate in the 80's and 90's, depending on their age. The younger they are the faster the heart rate.
Fire rated doors comply with certain standards (NFPA 80) and building codes so that the door functions to reduce the spread of fire and smoke.

Smooth muscles are involuntary muscles, muscles that you can not control, and are located in your organs like your stomach and intestines. Valves are located in your heart and they are like little doors that allow the blood to flow into the chambers when open and stop the flow when closed.
