Eight main organs 8

Brain The brain is the organ of thought, memory and feeling. It takes in what the senses pick up and controls the body.
Lungs The lungs bring oxygen from the air into the blood. They send carbon dioxide back out.
Heart The heart pumps blood round the body. It sits in the chest between the lungs, a little to the left.
Liver The liver makes bile, which the body uses to digest food.
Stomach In the stomach, food is mixed with acid. Then it moves on to the small intestine.
Kidneys The kidneys lie at the back, one each side of the spine. They filter the blood and make urine.
Small intestine Most digestion happens in the small intestine. Most of the nutrients pass into the blood here.
Large intestine What is left of the food passes into the large intestine. There it is dried to form waste.

Six more organs 6

Trachea (windpipe) Each breath in pulls air down the trachea into the lungs.
Diaphragm When the diaphragm tightens it moves down. That makes more room for the lungs, so air is pulled in.
Gallbladder The gallbladder stores bile from the liver until it is needed.
Pancreas The pancreas makes pancreatic juice. The juice helps digest food in the small intestine.
Spleen The spleen removes old and damaged red blood cells from the blood.
Bladder The bladder collects the urine made by the kidneys and stores it.

How it works

A child's head and body with fourteen organs drawn inside. The page starts with eight, from the brain down to the intestines; the other six are under Start from. A few organs that sit behind others are moved a little so you can see them.

From the top down

The brain is in the head. In the chest, the windpipe leads to the two lungs, with the heart between them. The diaphragm is the curved muscle under the lungs. Below it are the liver and the stomach, then the small intestine, coiled inside the large one. The kidneys are at the back, one each side of the spine.

Left and right are the child's, not yours: the heart leans to the child's left, which is the right of the picture.
Both lungs light up together, and so do both kidneys.

Questions and answers

What are the main organs of the human body?

This page starts with eight: brain, lungs, heart, liver, stomach, kidneys, small intestine and large intestine. The other six on the picture are the trachea, diaphragm, gallbladder, pancreas, spleen and bladder.

Where is the heart in the body?

In the chest, between the two lungs and a little to the left.

Which organs are in the chest?

The heart and the two lungs, with the windpipe bringing air down to the lungs. The diaphragm, a curved muscle, lies under them. When it tightens it moves down and air is pulled into the lungs.

What do the kidneys do?

The two kidneys filter the blood and turn the waste into urine. The urine collects in the bladder.
