Mechanics of Respiration: Human Anatomy.
The Respiratory system is responsible for the breathing process. The breathing process entails inhaling and exhaling air in the body, absorption of oxygen from the air to produce energy, and getting rid of the byproduct of the process which is the carbon dioxide. The respiratory system is divided into two tracts; the upper respiratory tract and the lower respiratory tract. The following organs.
Gas Exchange. In order to see how gas exchange occurs we need to look further into the lungs. Firstly we know that air enters the body through the mouth or nose, from here it moves to the pharynx (throat), passes through the larynx (voice box) and enters the trachea.The trachea splits into two branches, the left and right bronchus, each bronchus divides many times into smaller branches called.
Inspiration is normally an active process (requiring work). Expiration is passive, and usually longer than the time required for exhalation, resulting an a no-flow period. When breathing spontaneously, the work of breathing is minimised by keeping inspiratory times short and tidal volumes low - just enough to get rid of the produced CO2. To.
We get the oxygen to our cells with the respiratory system and by breathing. Breathing In We breathe in using a muscle called the diaphragm. It flattens out making our lungs expand and fill with air. When we breathe in, air gets forced through our nose or mouth, down our windpipe, and into bronchi tubes in our lungs. These bronchi tubes branch out and get smaller and smaller, like the roots or.
Breathing and Lung Mechanics. When under physical or emotional stress, more frequent and deep breathing is needed, and both inspiration and expiration will work as active processes. Additional muscles in the rib cage forcefully contract and push air quickly out of the lungs. In addition to deeper breathing, when coughing or sneezing we exhale forcibly. Our abdominal muscles will contract.
The respiratory system organs are separated into the upper and lower respiratory tracts. The upper respiratory tract includes the mouth, nose, nasal cavity, pharynx (windpipe and food pipe) and larynx or voice box. Each has a specific function to aid the flow of air into the body. Link.

Why do you breathe? Every part of your body needs oxygen to survive. Everyday functions of the body like digesting your food, moving your muscles or even just thinking, need oxygen. When these processes happen, carbon dioxide is produced as a waste product. The job of your lungs in this system is to provide these processes with oxygen and to get rid of the waste gas, carbon dioxide. Your brain.
