How each cell of a human body works????

What is a cell?

A Human Body Cell

Understanding about a body cell is essential to know about the entire body system.

Cells are the basic building blocks of all living things. They provide structure for the body, take in nutrients from food, convert those nutrients into energy, and carry out specialized functions.

  The human body is composed of 6,000 crore cells. Cells in an each organ is different from other organs. Means that the chemical composition constitute a cell becomes, different from organ to organ...(For example cells in our eyes are made up of different chemical elements, cells in our palm are made up different chemical elements and so on.,). But the basic function is same.

Whereas, Every cell has the following major parts in common.

Cytoplasm

The cytoplasm is fluid inside the cell that surrounds the organelles (Mitochondria).

Endoplasmic reticulum (ER)

This organelle helps process molecules created by the cell and transport them to their specific destinations either inside or outside the cell.

Golgi apparatus

The golgi apparatus packages molecules processed by the endoplasmic reticulum to be transported out of the cell.

Lysosomes and peroxisomes

       It's a recycling center of the cell. They digest foreign bacteria that invade the cell, rid the cell of toxic substances.

Mitochondria

       It helps to burn the glucose and oxygen to release the energy.

Nucleus

It is a command center, sending directions to the cell to grow, mature, divide, or die.

It also houses DNA (deoxyribonucleic acid), the cell’s hereditary material.

Plasma membrane

A membrane is like door to a cell. 

It does two things:

1. Consumes oxygen, minerals, vitamins and glucose/saturated starch/saturated corbo-hydrate from the blood stream.
2. And it discharges certain enzymes and all the excreted materials into the blood stream.

Ribosomes

Ribosomes are organelles that process the cell’s genetic instructions to create proteins. These organelles can float freely in the cytoplasm or be connected to the endoplasmic reticulum.

Each day 'n' crore cells are rejuvenated.

If it is true.... Why there are so many diseases comes to a person.

Go ahead for answers...

Every treatment / medication system (like allopathy or Homeopathy etc.) concentrates towards adding certain chemical components like zinc,
potassium, calcium, vitamins, Iron, sodium etc.,

A person who has proper composition (quality) with proper quantity of blood
does lead a healthy life. If not, fall sick.

Blood circulates from top to toe in your body continuously. Every second
a cell in the body takes something (e.g., glucose) from the blood and leaves
something (e.g., waste) into the blood stream.
