Respitory system.

Chronic Bronchitis:the bronchi become inflamed and clogged with mucus.

The human respiratory system picks up oxygen from the air we inhale and releases carbon dioxide into the air we exhale.

Air's route

Nose

Air enters the body through the nose, where it is filtered, moistened and warmed.

Pharynx, Larynx , Trachea

From the nose, air moves into the pharynx. Then, it passes through the larynx. which contains the vocal cords, and through the trachea

Lungs.

From the trachea, air moves into the bronchi. Each bronchus leads to one lung. The bronchi divide into bronchioles, which eventually end at alveoli.

Diseases

Emphysema:The loss of elasticity and eventual breakdown of the lung tissue

Lung Cancer

Gas Exchange and trasport

Oxygen and carbon dioxide are exchanged across the walls of alveoli and capillaries.

Chemical properties of blood cells allow for efficient transport of gases throughout the body.

Breathing

Inhalation

When you inhales diaphragm contracts and flattens raising the rib cage

Exhalation

This is the opposite, the diaphragm and the rib cage relax.
