What Makes a Body?

The human body is made from the same components as every other living thing. It is the way that they are put together that makes our bodies uniquely human. 

The basic materials are simple chemicals such as water, carbon, and oxygen, but they join to create more complex compounds. Trillions of microscopic cells become the building blocks of life, grouping together to form skin, bones, blood, and organs, until the body becomes complete.

 

Making a Human

Everything in the body  is made up of atoms, the tiniest building blocks of matter. 
  Atoms combine to  form molecules. 
 Millions  of molecules form every cell in the body. 
 There are  more than 200 types of cell,
with similar cells working in teams called tissues.
 The body's many organs and  systems are made up of-
 different tissues.

Atoms and molecules

The smallest parts in the body are atoms.
These tiny building blocks form the elements in the body, such as carbon. 
Atoms can also  join together in groups called molecules
for  example, water is a molecule, made from a  combination of hydrogen and oxygen atoms.

Cell

 

Molecules build up to create body cells.
There are about 37 trillion cells in the average human, with different types of cells carrying out a variety of body functions, from transporting oxygen to sensing light and colour in the eye.

Tissue

Cells performing the same  function are grouped together to form body tissues, such as skin, fat, or heart muscle. 

Blood is also a tissue, in liquid form.

Organs:


Different kinds of tissue combine to make larger structures called organs.
Each organ works like a machine,performing its own role. 
An example of an organ is the stomach, which plays a part in the process of digesting food.

Body system


Organs are at the centre of 12 internal body systems. 
Each system has a specific job to keep the body in working order.

The stomach is one of the main organs of the digestive system.

Complete human

When this complex combination of integrated systems, organs, and tissues work together, the human body is complete. 

Each individual component plays its part in maintaining a fully functioning body.
