The human body is a part of human anatomy. The human body is made up of many types of tissues and organs, working together to make the whole unit work.
It gets the energy from the food we consume and releases it as heat or uses it for activities in our bodies.
The basic functions that we have are –
- Respiration
- Circulation of blood and lymphatic fluid
- Excretion of wastes such as urine, blood plasma, and feces
- Generation of body heat by burning the food.
The human body is made up of two parts: the lower part and the upper part.
The lower part of the human body is the abdomen. It contains-
- Stomach, which stores and breaks down food into small parts to be absorbed by the intestines
- Liver, an organ that helps in digestion as well as storing nutrients and producing bile for digestion. The bile is stored in the gallbladder
- Large and small intestines, which absorb food by absorbing the nutrients they contain. The bile is drained into these two parts of the digestive tract as well.
The upper part of the human body is made up of:
- Lungs (located in the chest cavity) take oxygen from the air and release carbon dioxide into the atmosphere
- Heart, which pumps blood all over the body, to carry oxygen and nutrients to every cell in our bodies
- Brain, a very complex organ that is responsible for all of your actions, thoughts, and feelings. It contains a mind that controls everything you do
- The spinal cord, which carries messages from the brain down to all parts of our body. It is protected by 3 bones called vertebrae that are joined together at a specific angle (the neck).
