Respiratory System

 The respiratory is the anatomical system in organism. In this system gases molecules of oxygen and carbon dioxide exchanged through diffusion between the gaseous external environment and the blood.

Respiratory system divided into two parts.

1. Upper respiratory tract.

2. Lower respiratory tract.

Parts of upper respiratory tracts

1.Mouth, nose, nasal cavity.

2. Pharynx.

3. Larynx.

Parts of lower respiratory tracts

1. Trachea

2. Bronchi.

3. Bronchioles

4. Alveoli

5. Diaphragm

Air is full of harmful substance and chemicals. It includes mold, fungi, dust bacteria and pollutants. Particles only 3 to 5 microns in size reach in deep lungs. There are various ways to protect the respiratory system against the harmful particles. The particles travel through mouth and airways where the tiny hairs are located. These tiny hairs are called cilia. Those unwanted particles reach to digestive system through mouth kills by the digestive fluid of the stomach. If unwanted substances do reach the lungs, there are also little mobile cells, called phagocytes, which defend your respiratory tract.
