The primary organs of the respiratory system are the lungs, which function to take in oxygen and expel carbon dioxide as we breathe.
The gas exchange process is performed by the lungs and respiratory system. Air, a mix of oxygen and other gases, is inhaled.
In the throat, the trachea, or windpipe, filters the air. The trachea branches into two bronchi, tubes that lead to the lungs.
in our body when we r breathing it will go through nostrils. the nostrils purify the gas and sent in to the another parts through trachea,oesophagus.The nostrils are present in nassal cavity.
Once in the lungs, oxygen is moved into the bloodstream. Blood carries the oxygen through the body to where it is needed.
Red blood cells collect carbon dioxide from the body’s cells and transports it back to the lungs.
An exchange of oxygen and carbon dioxide takes place in the alveoli, in the lungs they are millions of one are there they are called alveolus.small structures within the lungs. The carbon dioxide, a waste gas, is exhaled and the cycle begins again with the next breath.
The diaphragm is a dome-shaped muscle below the lungs that controls breathing. The diaphragm flattens out and pulls forward, drawing air into the lungs for inhalation. During exhalation the diaphragm expands to force air out of the lungs.
Adults normally take 12 to 20 breaths per minute. Strenuous exercise drives the breath rate up to an average of 45 breaths per minute.
experiment on Breathing Mechanism
The physical movements associated with the gaseous exchange are called breathing. The various structures that are involved in the breathing mechanism are the respiratory passage, the lungs, the outer and inner intercostal muscles, the diaphragm and the muscles attached to the diaphragm.
The breathing movements are controlled by the three respiratory centres of the medulla oblongata and pons Varolli in the human brain. The three respiratory centres are the inspiratory, expiratory (in medulla oblongata) and pneumotaxic centres (in pons Varolli). The respiratory centres are stimulated by the carbon dioxide concentration of the blood.
Thus, the breathing movements are involuntary, to a large extent. However, we can control the rate of breathing and extent of breathing but not for long
the exchange of oxygen and carbon dioxide takes place in alveoli.
