The Respiratory system

The function of the respiratory system

the respiratory system is the system about the respiration of the cells in the body, the exchange of gases between organisms and the environment. the gases included are carbon dioxide and oxygen, the process occurs by breathing. the organs that are included in this system are the lung, diaphragm, nostril,mouth, trachea and bronchi.

Alveoli

The whole point of the respiratory system is the exchanges between the blood and the air, the oxygenate blood is transferred to the body,while the poor oxygen blood will exchange the CO2 with oxygen and the the CO2 will go out of the body , the process of exchanging occurs in the alveoli inside the lungs.

First we intake the air that has oxygen into our body the air travels down through trachea tube into the lung through the bronchi, the bronchus is attached to billions of alveolus and the alveolus are also attached to the capillaries.

then the oxygen in the air diffuse goes from the alveoli to the poor oxygen blood cell through the capillaries, the blood cell becomes oxygenated and travels out of the lungs throughout the parts of the body. After that it comes back to the lungs again and it diffuses the CO2 to the alveoli though capillaries and the CO2 gets out from your body by the time you exhale. Its basically a big cycle

2 disorders that occur in the respiratory system

Asthma : Asthma is a disorder that occurs in the respiratory system that affects the air way of the lungs to become narrowed and obstruct with mucus,causing the people who suffer from it to have difficulty breathing

The symptoms are wheezing while exercise or when having cold, cough mostly during the night time and chest tightness.

treatment for the asthma are several kinds of the medicine that help control the symptoms.

the prevalence of asthma by 2011 more than 235 million people suffered from asthma.

Emphysema : Emphysema is a disorder in the respiratory system that results in destruction of the alveolar walls. Symptoms are shortness of breath and enlargement of the thoracic cavity. Treatment involves removing sources of irritants, promoting the removal of bronchial secretions ,retraining people ,to breathe so expiration of air is maximized , and using antibiotics to prevent infections.The prevalence of emphysema estimated 4.7 million Americans ever diagnosed with emphysema ,92 percent are 45 or older.

How carbon dioxide and oxygen are transported into the blood

Oxygen enters the blood from the lungs and carbon dioxide is expelled out of the blood into the lungs . The blood serves to transport both gases. Oxygen is carried to the cells. Carbon dioxide is carried away from the cells.The oxygen transported by hemoglobin and the carbon dioxide bicarbonate and the other half is carbaminohemoglobin .
