how many chambers does the human heart have?
443388
4 chambers ...\nWithin the adult heart are two parallel independent systems, each consisting of an auricle, or atrium, and a ventricle; from their anatomical positions these systems are often designated the right heart and the left heart.

The normal resting heartrate varies due to many things but the normal range for an adult is considered to be 60 to 100.

The two chambers of the heart are completely separate.  There are no valves between the two.

Well to figure that out you can see how many times your heart beats in a minute. Then multiply that by 60. Then multiply that by 24 and you get your answer. For example:\nIf your heart beats 58 times in one minute\n58 x 60 = 3480\n3480 x 24 = 83,520\nSo if you heart beats 58 time in one minute, it beats 83,520 times daily.

The first link has an animated description.Anatomy of the Human Heart with Flash Illustration\n\n    *  The Right Atrium, receives "used blood" from the body. Blood will be pushed through the tricuspid valve to the\n\n    * Right Ventricle, the chamber which will pump to the lungs through the pulmonic valve to the\n\n    * Pulmonary Arteries, providing blood to both lungs. Blood is circulated through the lungs where carbon dioxide is removed and oxygen added. It returns through the\n\n    * Pulmonary Veins, which empty into the\n\n    * Left Atrium, a chamber which will push the Mitral Valve open. Blood then passes into the\n\n    * Left Ventricle. Although it doesn't always look like it in drawings done from this angle, this is the largest and most important chamber in the heart. It pumps to the rest of the body. As it pumps, the pressure will close the mitral valve and open the aortic valve, with blood passing through to the\n\n    * Aorta, where it will be delivered to the rest of the body.\n\n\nhttp://www.heartpoint.com/theheart.html\n\nhttp://www.pbs.org/wgbh/nova/heart/\n\nhttp://texasheart.org/HIC/Anatomy/Anatomy.cfm\n\nhttp://education.yahoo.com/reference/gray/illustrations/figure?id=505\n\nhttp://sln2.fi.edu/biosci/preview/heartsee.html\n\nhttp://www.geocities.com/Athens/Forum/6100/1heart.html\n\nSTRUCTURE OF THE HEART.\n\nhttp://www.infovisual.info/03/062_en.html\n\nhttp://www.cayuga-cc.edu/people/facultypages/greer/biol204/heart1/heart1.html\n\nhttp://www.geocities.com/Athens/Forum/6100/1HrtPics.html\n\nGood luck.\n\nKevin, Liverpool, England.

The heart is divided into the upper right atria and upper left atria (plural atrium), and the lower right and left ventricles. A septum divides them. Blood from the veins carries oxygen depleted blood, fewer red blood cells, to the heart and the arteries carry oxygen enriched blood to the body. It is the hearts job, a poweful muscle, to pump blood through the body.\n\nFor more imformation please click on the blue link below in the sources box.

Fish have a 2-chambered heart in which a single-loop circulatory pattern takes blood from the heart to the gills and then to the body.  Mammals have a 4-chambered heart, with complete separation of both systemic and pulmonary circuits.

Ooooh, that has to do with a quote from Clooney in Oh Brother where art thou.... the chambers of the human heart.

In the human anatomy, we have 2 atria and 2 ventricles.  The ventricle structure works like a bladder in a water pump to create the pressure to push the blood out into the circulatory system.  After the ventricle contracts and is empty, a supply of blood is needed to refill for the next contraction.  Think of the atrium as a bucket ready to dump into the ventricle.  It allows fast refill at low pressure.

All right, I'm first going to explain, briefly, the structure of the cardiovascular system, and then I'll move on to how the blood transports oxygen specifically.\n\nYour heart pumps blood from the right ventricle to your lungs, where it exchanges carbon dioxide for oxygen, and then continues to your left atria. The left atria pumps the blood to the left ventricle, which pumps blood through your arteries  to your capillaries, where the oxygen is released so that cells can use it. Carbon dioxide is picked up, and the blood continues to the veins, and back to the right atria.\n\nNow, your blood contains red blood cells, which contain two important molecules, hemoglobin and myoglobin. Both have a high affinity for oxygen, so, in your lungs, where there is a high oxygen concentration, oxygen binds to each of these two molecules (until the equilibrium point is reached). The red blood cells are pumped throughout the body. \n\nIn the body, the concentration of oxygen is lower than in the surrounding atmosphere, so the amount of hemoglobin (and myoglobin) which is binding oxygen decreases until it reaches the new equilibrium point. Active tissues use oxygen quickly, forming lots of CO2, which enters the blood, and is converted to carbonic acid by red blood cells, using the enzyme carbonic anhydrase. The change in pH lowers the affinity of hemoglobin for oxygen, so more oxygen is released from other red blood cells near working tissues. The carbonic acid is released back into the blood from red blood cells, where it dissociates into a proton (H+) and a bicarbonate ion. It travels through the blood back to the lungs, where it is converted back into CO2, and diffuses across the transport surfaces of the lungs due to the concentration gradient. Then the cycle starts over.

Octopus it actually has 3 hearts. Each gill has its own heart. Blood picks up oxygen in the gills, but after going through capillaries, it loses pressure. The third heart then pumps the oxygenated blood to the tissues all over the body.

the ventricles are larger than the atria and are the bottom two chambers, where as the atria are the top two chambers. The left ventricle has a thicker wall for greater volume of blood to be pumped out. The appearance is really just a hollow chamber for both of them...

The average blood cell makes a round trip through the body's arteries and veins every 60 seconds, and can hit speeds of up to 10 mph. The heart pumps your five quarts of blood around your body 500 times a day.

No.  The heart is just a muscle.  If you exercise, it beats more, but gets stronger and lasts longer.

heart rate is defined as the number of beats( systoles) the heart produces per unit of time( ussually per minute).\nBlood pressure is the pressure exert by the blood to the vessel´s walls( the arteries and the veins).
