respiratory system
What is the respiratory system?
The respiratory or respiratory system is responsible for taking up oxygen (O2) and remove carbon dioxide (CO2) from the cell anabolism.
Structure of the respiratory system
1. -This consists of bronchi, nostrils that these are the ones that carry air to the lungs where gas exchange occurs.
2. The diaphragm is the main muscle that is responsible for air inhalation it contracts and expands the chest cavity.
3. In exhalation the diaphragm relaxes and the air is expelled through the lungs.
Epiglottis.
It is a cover that prevents food from entering the larynx and trachea during swallowing. It also marks the boundary between the oropharynx and hypopharynx.
Nostril
Larynx
It is a conduit whose main function is filtration of inspired air. It allows the passage of air into the trachea and lungs and closes to not allow the passage of food during swallowing itself if desired and has not has the vocal organ function, ie produces the sound.
In the nostrils is the main way of breathing, by which the air enters. Consists of two large chambers whose function is to allow the entry of air, which is moistened, filtered and heated to a certain temperature through structures called turbinates.
Pharynx.
Membranous is a muscular tube which helps the air to spill into the lower airways.
Conclusion
Trachea
Provides a way open to the air inhaled and exhaled from the lungs.
Bronchioles
Directs the air that goes through the bronchi and bronchioles terminating in the alveoli.
BRONCHI.
ALVEOLI
Drive the air going from the trachea to the bronchioles
Where hematosis occurs (allows gas exchange inside the blood removes carbon dioxide and contains oxygen).
The respiratory system is essential for human survival, and that through it we have the process and the act of breathing.
He is responsible for taking up oxygen (O2) and remove carbon dioxide (CO2) from the cell anabolism.
LUNGS
lung function is to perform gas exchange with the blood, so the alveoli are in close contact with capillaries.
Intercostal muscles.
The main function is intercostal muscle to mobilize the air volume serving for, after a proper gaseous exchange, providing oxygen to the various tissues.
Diaphragm
Muscle separating the chest cavity (lungs, mediastinum, etc..) of the abdominal cavity (intestines, stomach, liver, etc.). Involved in respiration, decreasing the pressure inside the chest cavity and increasing the volume during inhalation and increasing the pressure and decreasing the volume during exhalation. This process is carried out primarily by the contraction and relaxation of the diaphragm.
