Do you see tiny ''doors'' that open and close as blood is pumped through the heart?

These "doors" are the following valves:
- Tricuspid Valve - arterioventricular valve of the right side
- Pulmonary Semilunar Valve - right side of the heart
- Mitral or Bicuspid Valve - AV valve of the left side
- Aortic Semilunar Valve - left side of the heart

What act as doors between the chambers of your heart?
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).
Why does the heart has valves?
Valves are the "doors" which allow the proper amount of blood into each ventricle of the heart so it does not "explode" or push too much into the body. When high blood pressure occurs the culprit can be a defective valve that is leaking or failing to open and close properly. Not many people have that type of high blood pressure. There are many types of high blood pressure which doctors can determine by listening to the valves in the heart or elsewhere.
What is tricky about the left and right sides of the heart?
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.
What part of speech is doors?
The word 'door' is a noun, a word for a movable structure used to close off an entrance or a part of a piece of furniture; a word for a thing.
Since the valves act as the doors of the heart what might happen if these doors do not close?
The valves have to open to let blood flow into a chamber, and close before the blood flows back. If the valves do not open and close precisely on schedule, or if they fail to open or close completely, the blood will not flow efficiently. This can cause fluctuations in blood pressure, lack of flow to organs, or damage to the muscles of the heart. For example, if the aortic valve between the heart and the aorta does not close after the left ventricle contracts, there will be back pressure into the ventricle, less blood pumped out of the heart, and lower pressure in the arteries.
What keeps blood from the flowing backwards?
Blood vessels have valves that act like doors really. Also blood is pumped (pushed) out and around your body by each pump of your heart, each pump pushes more blood through, there is nowhere else to go but forward. It doesn't suck it back .
