Human Respiratory Equipment - Colds make a stuffy nose. The nose interfere with breathing. As a result we can not breathe with relief. Why so? What is the relationship between nasal congestion and respiratory processes? The nose is one of the breathing apparatus. If our nose is healthy, we can breathe with relief. However, if the nose is blocked, we will be hard to breathe. What does it breathe? What tools are used for breathing?

Breathing is an activity to breathe the air and let out the air. Air containing various gas components, one of which is oxygen (O2). Oxygen is what is needed by the body. Oxygen gets into the body through breathing. Furthermore, respiration produces carbon dioxide (CO2) released from the body. Breathe using breathing devices. What's respiratory devices?

Human respiratory apparatus consists of the nose, throat, and lungs.

1. Nose

The nose is out of the entrance of air breathing. Air enters through the nostrils toward the nasal cavity. The hair found in the nasal cavity of the nose and mucous membranes. Nasal hair and mucus membranes function to filter the incoming air is free from dust and germs. Thus, the air we breathe clean from dirt, dust, germs or disease. On the nose the air also have to adapt the temperature and humidity.

2. Throat (Trakhea)

Air breathing from the nose down to the throat (trakhea). Throat is a channel length of about 9 cm. The throat feathers are fine. Works fine hairs filter the air of impurities can still qualify for the throat. Edge trakhea branched into two parts. The branches are called the bronchi. Right bronchus toward the right lung. Bronchi left into the left lung.

3. Lung

The lungs are in the chest cavity above the diaphragm. Diaphragm is blocked between the chest cavity and abdominal cavity. Lungs were two that is left lung and right lung. Left lung consists of two lobe. The right lung consists of three lobe. Lung packaged by the lining of the lungs called the pleura.

In the lungs there are branches of the bronchi called bronkiolus. Bronkiolus also has ramifications that number very much. The branches are very fine and thin. Every branch tip forming a thin-walled sacs called alveoli. The alveoli are very thin bubble. Bubble wrapped capillary blood vessels. In alveolar gas exchange occurs O2 and CO2.

At the air we breathe to the alveoli, oxygen through blood capillary walls. Oxygen bound to hemoglobin (Hb) blood. After that, blood will circulate oxygen throughout the body. In the body, oxygen is used for the formation of energy. In the process of energy produced and carbon dioxide (CO2). CO2 is tied back by blood hemoglobin. After that, the blood will bring CO2 to the lungs. CO2 from the lungs toward the throat, then into the nostrils to be removed from the body.

Breathing/Respiratory Process
Inclusion of O2 and CO2 on respiratory discharge occurred at the sidelines of the respiratory process. These processes are governed by the muscles of the diaphragm and the muscles between the ribs. At the time of the diaphragm muscle to contract gasps. As a result, horizontal diaphragm, chest cavity grows, and the air in the lungs. When the muscles between the ribs to shrink , the lungs fill with air . Muscles between the ribs that causes chest cavity shrinks enlarged and air into the lungs . The process of breathing air entry into the lungs is called inspiration.

At the time of exhale, the diaphragm and the muscles between the ribs muscles slacken. As a result, narrow chest cavity and the lungs deflated until the CO2 in the lungs pushed out. The process is the process of expiration. Advertisement
