Heart

An enlarged ventricle is usually due to either cardiomyopathy (a weakening of the heart muscle) or valvular heart disease. Valve disease is usually treated by correcting the underlying valve problem (initially with medicines, often later with surgery). The most common cause of an enlarged ventricle is cardiomyopathy,a serious disease in which the heart muscle becomes inflamed and doesn't work as well as it should. Initial treatment is with medications, such as diuretics, digitalis, vasodilators (ACE inhibitors and/or ARB inhibitors), and beta blockers, such as carvedilol (Coreg) or metoprolol (Lopressor, Toprol XL). In more severe cases special pacemakers or defibrillators are used. Only in the most difficult cases are heart transplants occasionally required. Hope this helped you out. Good luck!

For one thing, you will smell it. It smells kinda' like tar. You will also have smoke coming out of the exhaust pipe. Your spark plugs will also look kinda' black from burning oil because the oil is probably being burned with fuel. I'm not sure about this part, but I think that oil is probably getting into the pistons of the engine. That would mean you have a leak somewhere. I think this can usually be fixed by replacing the gaskets. Call an automotive store for more specific information.

That is one cause. If any blood vessel gets blocked by a blod clot or an air embolism, it can cause a heart attack. The heart can also stop beating if the electrical system gets disrupted due to an electrical shock, or some type of congenital defect in the electrical system.

It is the aorta.

The waves of excitation would not be carried to the bottom of the heart first and it would spread over the ventricular walls from top to bottom causing the ventricualr muscle to contract in a way that it pushs the blood downwards. The blood would however end up going through the arteries because of the immense pressure but less will be pumped through the arteies with every contraction hence leading to less blood being pumped in the heart

Blood enters the right atria from the superior and inferior vena cava. Then it flows down into the right ventricle. Then to the lungs. Back to the left atria. Down into the left ventricle and out the the rest of the body.

Well, I'm not sure if we're talking about the same thing, but I recently learned that there are two kinds of blood (sort of) - blood with oxygen, and blood without oxygen. If the blood with oxygen and the blood that has yet to receive oxygen is mixed, then the person will always be tired. So there's a part in the heart that separates the blood that already received oxygen and the blood that is on it's way to receive oxygen. That part (I forgot what it was called) grows in shortly after birth. I hope we're talking about the same parts.

the left atrium

Yes.

Shock is a common occupational hazard associated with working with electricity. A person who has stopped breathing is not necessarily dead but is in immediate danger. Life is dependent on oxygen, which is breathed into the lungs and then carried by the blood to every body cell. Since body cells cannot store oxygen and since the blood can hold only a limited amount (and only for a short time), death will surely result from continued lack of breathing.

However, the heart may continue to beat for some time after breathing has stopped, and the blood may still be circulated to the body cells. Since the blood will, for a short time, contain a small supply of oxygen, the body cells will not die immediately. For a very few minutes, there is some chance that the person's life may be saved.

Hello so i really need an answer like a professional. So me and my boyfriend had unprotected sex through the month of march to like late april and i think im pregnant. I went to the hospital sometime in april and we took a urine pregnancy test and it came back negative. But i think i had taken that test too early so ive been having alot of symptoms like nausea,back pains,my nipples are sore and tingly,i feel bloated,im fatigued etc. march 20th was the last time i had a normal period cycle that was its normal 5 days. In april i had spotting a week before my normal period was supposed to come it was 4 days long and in may i spotted again and it was even lighter it was only 3 days long. And lately ive been having way more back pain,ive been feeling more fatigued,ive been feeling really heavy, and ive been more nauseous i did take 3 different home pregnancy tests and they all came out negative but i still feel like i could be pregnant. And my stomach has never been hard and now its hard and when you poke it you can really feel something inside of me. I also took homemade pregnancy tests like the peeing in bleach and it bubbled and fizzed alot and The peeing in pinesol and it changed colors. Im going to the doctors soon but i need some advice or help please!

The right side of the heart pumps deoxygenated blood to the lungs, where it picks up oxygen and returns to the left side of the heart.

The left side of the heart contains oxygen-rich blood. The right side of the heart contains deoxygenated blood.

For preservation of soft body parts as fossils in rock, burial, and an anoxic (lacking Oxygen) Environment are necessary.

Burial provides a medium in which to preserve the body parts.

A lack of oxygen (anoxia) will prevent all biologic activity, such as decay or predation, allowing the buried body part to survive long enough for mineralization (gradual replacement of original biological matter with minerals such as quartz) to occur.

Anoxic conditions are relatively rare on a geologically significant scale; they exist usually in stagnant water, where biologic activity has depleted the oxygen supply, and no fresh water flows exist to clear out and replace the anoxic water.

If your question is about peserving actual soft body parts, not as fossils, the answer is that dry and cool conditions, or freezing conditions, will retard decay, and thus will preserve organic material such as soft body parts for a time.

increase its rate and force of contraction

yes it can your heart can work at low rates depending on many things including everyday activity. 40% is actually a normal percentage. most healthy teens range from 60-65 percent

It's actually the Mediastinum.

Right Ventricle

the size of the right atrium is smaller that the left atrium.

No. The bones and teeth are the last to disintegrate, and only at high enough temperatures. All organs and tissue are burned up quite quickly, and at about the same time.

Because it has to be pumped into the ventricles with some pressure so they can fill up with blood before getting pumped out of the heart and into the lungs and the body.

The function of the spleen is the same in the human body as in other vertebrates. It plays a really big role with red blood cells and the immune system. In terms of red blood cells, it removes worn out cells, recycles iron and also keeps some extra blood handy in case of a hemorrhagic shock. It can synthesize antibodies in the white pulp area (it has white and red pulp) and through blood and lymph node circulation, remove antibody-coated bacteria and antibody-coated blood cells.

The red pulp area apparently keeps half of the body's monocytes which basically aid tissue healing while turn into dendritic cells and macrophages.

The absence of spleens increases risks for certain infections, so it is often likened it to a giant lymph node.
