What Are the Major Organs of the Body & What Do They Do?

The major organs of the body are simply the most well known organs but may not be important if they work alone, as they need to work in co-ordination with all other organs in the body.

Starting at the top of the human body, the brain processes information and is the body’s control center. It handles the processes of the central nervous system and cognition. The eyes detect light and convert it into electrical signals which the brain interprets as vision.

The chest cavity contains some major organs. The heart’s main function is to use the circulatory system to pump blood through out the body. The lungs oxygenate blood through the intake of air and filter out any contaminants from the air which they consider harmful to the bloodstream.

The stomach and intestines are part of the digestive system. The stomach uses its acidic content to break down foods before being processed by the intestines which extract nutrients from the food then expel the waste.

The liver generates bile for metabolism. The kidneys maintain the electrolyte balance and are connected to the bladder which expels fluid waste. The spleen breaks down old blood cells and stores blood. The pancreas produces hormones and enzymes.

The bones are the framework and shape of the body and also store minerals and produce fresh blood. The skin is the largest organ. It provides covering, regulates temperature, absorbs nutrients, processes vitamins B and D and provides sensitivity.
