What are the Largest Organs in Human Body?
The human body consists of different organs which perform various functions. These include the brain, heart, lungs, liver, kidneys and intestines. Each one of these organs contains many cells called neurons or nerve endings. They send signals to other parts of your body through nerves and blood vessels. All these nerves and blood vessels carry messages from one part of your body to another.
There are two main types of organs: those with a large number of cells and those without any cells at all. The largest number of cells is found in the brain, followed by the heart, then the lungs and finally the digestive system.
The smallest number of cells is found in our skin.
In order to survive, each of these organs needs nutrients. Some of them require oxygen while others need carbon dioxide (CO2).
Oxygen is provided by the air we breathe; CO2 comes from food and water. If there was no food or water, the tissues would not grow properly and they could not function normally. Without proper growth, the organs cannot provide their required services efficiently.
The human body has many working parts. Some work all the time, while others only work when needed.
Every organ and part of your body has a specific job to do in order for you to remain alive. The heart may be a strip of muscle that pumps blood, but it is also the symbol of love!
The brain is the control center for the body. It tells everything what to do and when to do it.
The brain controls the body according to input from the senses and instructions contained within your DNA. It also monitors all processes in your body and coordinates all activities.

Skin: Skin covers your outer surface and consists of several layers of tissue. The top layer, which you can touch and see, is called the epidermis.
It protects the more delicate tissues below. The epidermis contains cells that produce a natural skin moisturizer. These cells produce an oil called sebum. Sebum keeps the top layer of skin moist and waterproof. The bottom layer is thicker and denser. This part of the skin is called the dermis. It contains sensory cells that detect pain or pressure. It also contains nerve endings that provide feelings to your body. Skin is the largest organ in your body by weight.
