This is for my anatomy and physiology class in high school.  I need this answer and other sources for it as soon as possible.  I have essays to do (this is why I have this question).  I need reliable sources like mayoclinic.com, healthatoz, wikipedia, etc.  Please send any information.

The embolus is a clot caused by a buildup of cholesterol, etc. (the arteriosclerosis) which in this case breaks free and lodges in the right upper lobe of the lung. This blockage of blood prevents oxygenated blood from flowing back to the heart and entering the left atrium. Because no oxygen is reaching the heart, the heart weakens and eventaully fails. \n\nThe short easy answer - The clot blocks oxygenated blood from reaching the heart which suffocates and fails.

Best way to research this is webMD.com.  Call any pharmacist and they will give you all the details and may even have a pamphlet they can give you.

All of the above are well understood, it's just that skeletal and cardiac mucsle are more complicated, therefore there is more information on them.  Smooth muscle contraction can function solely on its intrinsic plexus, its built-in nervous system that only receives fine tuning from the para and sympathetic nervous systems.  It even has its own immune system, Peyer's Patches for example.

I suppose the obvious answer is the best.  Go see a doctor.  If you can't find one, then search online using a search engine such as google.

The reason why it is there is that it is more efficient to have a wall. It separates oxygenated from non-oxygenated blood so only oxygenated blood is sent to muscles.\n\nAmphibians and reptiles don't have a wall separating the oxygenated from non-oxygenated blood, they are alive, but their circulatory system is less efficient because some of the blood travelling to the muscles doesn't contain any oxygen.

Without a doubt, I believe your question has validity. But with that said, it will be necessary to check into my archives on this particular subject matter. Although the question has some important thoughts, I would advise you to seek a professional who can best serve you. Although I will do my best to be forthright in giving you the best answer possible, I am afraid anything that I write would be taken entirely out of context. For this reason, and this reason alone, I will say there are always good answers; but rarely are there perfect answers. So my answer can not and will not serve your needs for anything medical. I will only answer by saying this is my best sentiment; it in no way reflects my moral values or any opinion of my business, that will remain incognito.
