how many chambers are there in the human heart??
403952
4 total, two atrial chambers and 2 ventricular chambers

In fish, the circulatory system has only one circuit, with the blood being pumped through the capillaries of the gills and on to the capillaries of the body tissues. This is known as single circulation. The heart of fish is therefore only a single pump (consisting of two chambers).\nSee ilustration in \nhttp://www.emc.maricopa.edu/faculty/farabee/biobk/BioBookcircSYS.html

The heart is a powerful muscle slightly larger than your clenched fist. It works as a pump to send oxygen-rich blood through all parts of your body. Blood contains oxygen and nutrients that every cell in your body needs to survive. The oxygen-rich blood travels throughout the arteries and vessels, nourishing the body so that it can function properly.\n\nYour heart will beat an average of 100,000 times per day. In that time, it pumps more than 4,300 gallons of blood throughout your entire body.

The heart is what pumps blood throughout the body, keeping all organs functioning. Blood flows to the body through arteries and blood flows back to the heart through veins. Its all one big system - the circulatory system.

Common animal (including human) organs include the heart, lungs, brain, eye, stomach, spleen, pancreas, kidneys, liver, intestines, skin, uterus, and bladder.\n\nBlood vessels exist in varying calibers:\n\nArteries \nAorta (the largest artery, carries blood out of the heart) \nBranches of the aorta, such as the carotid artery, the subclavian artery, the celiac trunk, the mesenteric arteries, the renal artery and the ileac artery. \nArterioles \nCapillaries (the smallest blood vessels) \nVenules \nVeins \nLarge collecting vessels, such as the subclavian vein, the jugular vein, the renal vein and the iliac vein. \nVenae cavae (the 2 largest veins, carry blood into the heart)

a fish heart has 3 chamber. a human heart has four. they are the same in the fact that they have a "double pump", that is, they blood fish goes to get oxygenated, then come back to the heart, and then goes to the body. unlike a human heart, however, is that a fishes heart does not have a diveded heart like humans do, so they oxygenated blood mixes with the deoxygenated blood, so it is a less efficient sytem.

With the average heart rate of 72 beats per minute the heart will pump about 5 litres per ventricle, or about 10 litres total per minute. This is called the cardiac output. In a trained athlete the total cardiac output is about 20 litres. If we multiply the normal, non-athlete output by the average age of 70 years, we see that the cardiac output of the average human heart over a life time would be about 1 million litres, or about 250,000 gallons(US)!

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.

The heart pumps blood to all parts of the body. The heart is made of tissue and is supplied with oxygen-rich blood and nutrients. Although the chambers of the heart are full of blood, the heart tissue itself is fed from a network of blood vessels traveling on their surface. These are called the coronary arteries.\n\nThere are three major coronary arteries. They are:\nleft anterior descending \ncircumflex \nright coronary artery

HI, your doctor said that your left side of your heart is larger than your right?, well the heart is broken down into 4 chambers left atrium and ventricle, as well as the right atrium and ventricle. So if he's saying that the left side is larger..that would mean that you have a hypertrophy which is simply saying your hearts muscle wall is larger on that side. There could be several reasons for this to happen, but generally your hearts working overtime to get the blood outside the heart and to the rest of your body. It would help to know your age, and if you had any congenital defects when you were born such as ventriclar septal defects or atrial septal defect, fallots tetralogy etc...i don't know if you'll know what that means but i guess if you don't what they mean then you most probably dont have it. Maybe you got long term hypertension, you gotta give us some more info so we can actually answer your question.

Frog has 3-chambers. A humam has 4-chambers and the blood w/ o2 don't mix w/ the blood w/ c!!

Put your hand on your heart. Did you place your hand on the left side of your chest? Many people do, but the heart is actually located almost in the center of the chest, between the lungs. It's tipped slightly so that a part of it sticks out and taps against the left side of the chest, which is what makes it seem as though it is located there.\n\n\nHold out your hand and make a fist. If you're a kid, your heart is about the same size as your fist, and if you're an adult, it's about the same size as two fists. \n\n\nYour heart beats about 100,000 times in one day and about 35 million times in a year. During an average lifetime, the human heart will beat more than 2.5 billion times. \n\n\nGive a tennis ball a good, hard squeeze. You're using about the same amount of force your heart uses to pump blood out to the body. Even at rest, the muscles of the heart work hard--twice as hard as the leg muscles of a person sprinting. \n\n\nFeel your pulse by placing two fingers at pulse points on your neck or wrists. The pulse you feel is blood stopping and starting as it moves through your arteries. As a kid, your resting pulse might range from 90 to 120 beats per minute. As an adult, your pulse rate slows to an average of 72 beats per minute. \n\n\nThe aorta, the largest artery in the body, is almost the diameter of a garden hose. Capillaries, on the other hand, are so small that it takes ten of them to equal the thickness of a human hair.\n\n\nYour body has about 5.6 liters (6 quarts) of blood. This 5.6 liters of blood circulates through the body three times every minute. In one day, the blood travels a total of 19,000 km (12,000 miles)--that's four times the distance across the US from coast to coast.\n\n\nThe heart pumps about 1 million barrels of blood during an average lifetime--that's enough to fill more than 3 super tankers. \n\n\nlub-DUB, lub-DUB, lub-DUB. Sound familiar? If you listen to your heart beat, you'll hear two sounds. These "lub" and "DUB" sounds are made by the heart valves as they open and close.

It beats around 100,000 times per day, pumping 5.5 litres of blood through 150,000km of blood vessels three times every minute. During an average life span, the heart will beat 2.5bn times.

This is a problem. Medical dictionaries define an organ as a relatively independent part of the body that carries out 1 or more special functions. Lists of internal organs usually list 22. The skin would make 23. Eyes and ears are certainly organs and in the skin are sense organs. So there isn't a definite answer or an official answer.
