Structure and Function of LUNGS
In this Biology video in Hindi for we explained the structure and function of lungs.
In human, air is breathed into lungs. That air passes through nasal cavities, nasal passages, pharynx, larynx, trachea, bronchi, bronchioles and it reaches the alveolar sacs, where oxygen and carbon dioxide are exchanged.
Nasal Cavity : The nasal passages filter and warm the air, and make it moist before it goes into the lungs. They also contain special cells that are involved in the sense of smell.
Pharynx : It carries food to the esophagus and air to the larynx.
Larynx : It involves in producing sound and protecting the trachea against food aspiration.
Trachea : It is composed of about 20 rings of tough cartilage. Due to which it is a stiff, flexible tube, it provides a reliable pathway for air to enter our body.
Bronchi : A bronchi conduct air into the lungs. Like trachea, these are also supported by cartilage.
Bronchiole : The bronchioles deliverair to the alveolar sac. Unlike bronchi, the bronchioles no longer contain the cartilage.
Alvioli : Alveoli are hollow, cup-shaped cavities in the lungs where oxygen is exchanged for carbon dioxide.
When we breathe in, we lift our ribs and flatten our diaphragm. As a result the chest cavity becomes larger. Because of this, air is sucked into the lungs and fills the expanded alveoli. The blood brings carbon dioxide (mostly in dissolved form) from the rest of the body for release into the alveoli. Oxygen in the alveolar air is taken up by respiratory pigments, haemoglobin in R.B.C. to be transported to all the cells in the body. During the breathing cycle, the lungs always contain a residual volume of air so that there is sufficient time for oxygen to be absorbed and for the carbon dioxide to be released.
