THE RESPIRATORY SYSTEM

Why do we have to breathe?

The respiratory system is essential to live. We breathe because our body needs energy to run jump, study, talk, etc. The cells need oxygen in order to create energy. Oxygen reaches the cells with the respiratory system and breathing. Without oxygen, the cells would die and we would also die.

The main parts are:

• Nose and Nasal Cavity
• Mouth
• Pharynx
• Larynx
• Trachea
• Bronchi and bronchioles
• Lungs
• Muscle of respiration

How the respiratory system works?

Inhale

We breathe through the nose or through the mouth. The air traverses the trachea reaching the lungs. When we breathe we use the diaphragm making our lungs fill with air.

Alveoli

They are small sacks of air. They pass oxygen to the red blood cells.

Exhale

The alveoli not only transmit oxygen to our blood, they also help eliminate carbon dioxide in the blood.

Illnesses that can affect to the respirator system?

The most ommon problems of the respiratory system are:

• Asthma

• damaged blood vessels

Relationship

The circulatory system, the respiratory system and the excretory system work together all the time so that our body can move. The circulatory and respiratory system causes blood and oxygen to travel throughout our body.

Circulatory system. The main relationship with the respiratory system is thanks to the heart. The heart pumps blood with oxygen throughout the body.

Excretory system. when the respiratory system picks up oxygen from the outside through the nose or mouth, the excretory system is in charge of eliminating the waste products or gases that we do not need.
