What does each side of your heart do?

The heart is made up of four chambers. The two upper chambers are called atrium and the two lower chambers are called ventricles. The right side of the heart pumps blood to the lungs and exchanges carbon dioxide for oxygen, then returns to the left side of the heart, where the oxygenated blood is pumped back to the body. This cycle repeats endlessly.

Which part of heart allows for the exchange of nutrients and oxygen?

The exchange of nutrients and oxygen does not take place in the heart. The exchange of oxygen takes place in the alveoli of the lungs and the exchange of nutrients takes place at numerous sites around the body, but the most predominant is the duodenum and ileum of the small intestine.

Why does the heart rate decreased in long term of sport?

Cardiovascular efficiency depends on a number of factors. One measure is called stroke volume, which is the volume of blood pumped per heartbeat. A fit individual has a larger stroke volume, which means a greater volume of oxygen is delivered to the body per heartbeat. This is also the reason fit people have a lower resting heart rate. As mentioned, muscles reqire a given amount of fuel, even at rest, which doesn't change with exercise training. Because exercise training has increased the volume of oxygen that can be delivered to muscles per heartbeat, the heart needs to beat less to do the same job. Therefore, the heart rate is lowered.

What is the meaning of stets as related to the heart?

It is "Stents" and not stets. Stents are small, metallic, porous cylindrical structures that are placed within a blood vessel to prevent re-narrowing of the blood vessel due to chloesterol deposition. Usually these stents are placed after a "ballon angioplasty", a medical surgery to clean the deposited cholesterol plaques in the blood vessels (coronary arteries), to prevent re-narrowing or furhter deposition of chlolesterol that may block the coronary arteries and may lead to Angina or heart attack. In some cases these stents may also be coated with drugs such stents are called as drug eluting stents.

Why is the left side of heart more muscular?

Here is a nicer answer to your question:

Because if you think about it, the left side of your heart is pumping blood to your ENTIRE body, while the right side is pumping only to the lungs. for example, say if you used your left arm to lift weights twice as often as you did your right arm, your left arm will naturally be larger cause it works harder. Hope this answer your question.

If a person is walking down a hallway in their place of employment and has a heart attack and strikes their shoulder causing injury to the shoulder is the heart attack and the shoulder injury covered?

It's my understanding that whatever workman's comp. covers must be the result of normal activities associated with the performance of the job. Injuries at the workplace occurring in a fashion not associated with the performance of the job may or may not incur liability against the company. It's kinda like the "wet-floor" scenario. As far as what you've described, there appears to be no culpability on the part of the company which either caused the heart attack or the resultant fall which led to additional injury. See a lawyer if in doubt. jb
