How the whole inhalation process work?
The diaphragm (muscle) contracts, causing an expansion of the intrapleural cavity (space between the pleura of the lungs), and the lungs expand.
When the lungs expand, it makes a partial vacuum (negative pressure) inside the lungs, which pulls air into them (from the nose/mouth, into the bronchii, through the alveoli, and into the lungs).
As air passes through the alveoli (which are tiny air sacs surrounded by capillaries), the oxygen in the air binds to the hemoglobin in red blood cells, turning it into oxyhemoglobin, and giving the blood its reddish color. This oxygen-rich blood is pumped back into the heart, and out to the rest of the body, where the oxygen can detach from hemoglobin to be used in oxidative phosphorylation (generating energy for cells).
Once the cells use the oxygen to generate energy (in the form of ATP, adenosine triphosphate), they form carbon dioxide.
This carbon dioxide is reattached to hemoglobin in red blood cells to form carboxyhemoglobin, which gives oxygen-poor blood a bluish color.
This blood is pumped back to the heart, and back through the alveoli in the lungs, where the carbon dioxide detaches, is breathed out of the body, and fresh oxygen can be breathed back in, starting over the entire process again.
Inhalation (Inspiration) results from the contraction of the external intercostal muscles, in tandem with the contraction (flattening) diaphragm as well. This increases the volume in the thorax and hence lowers the pressure inside the lungs compared to the outside environment. Air moves from a region of high pressure to a region of low pressure and so the process of inhalation is complete.
The diaphragm & the external intercostal muscles (the muscles between the ribs that course downward) are the two most important muscles of inhalation, but there are many other muscles that also contribute to this process. Other muscles of inhalation include: -Pectoralis major -Pectoralis minor -Serratus anterior -Costal levators -Subclavius -Serratus posterior superior -Serratus posterior inferior
Respiration is a process which involves taking in of oxygen through inhalation to supply to the tissues and release of carbon di oxide through exhalation from tissues to the atmosphere. During inhalation the rib cabe expands by moving out. The diaphragm moves down. These two process occur simultaneously to increase the air holding capacity of the lungs by expanding the alveolar cells of lungs.
During inhalation the diaphram expands pulling the lungs down and compressing the abdominal cavity. During exhalation the diaphram contracts allowing the lungs to return to normal and the air to be expelled. Inhalition is an active process with exhalition as a passive process. The law of physics that explains this is Boyle's Law.
These are the muscles that move the rib cage and they work together: Diaphragm (Prime mover of inhalation). If you need to breathe deeper you will use these: Scalenes (Elevate rib cage, assist in inhalation) Sternocleidomastoid (Elevate Rib Cage, assist in inhalation) Pectoralis minor (Elevate Rib Cage, assist in inhalation) External Intercostals (Elevate rib cage, assist in inhalation) Internal Intercostals (Depress, assist in exhalation) The diaphragm is under both voluntary control (holding your breath) and…
How do the Direct and Manage Project Work process and the Monitor and Control Project Work process interact with each other?
The monitor and control project work process often generates change requests that, if approved, become inputs to the direct and manage project work process. work performance data, an output of the direct and mange project work process, is processed and work performance information becomes an input to the monitor and control project work process.
Scalenes (Elevate rib cage, assist in inhalation) Sternocleidomastoid (Elevate Rib Cage, assist in inhalation) Pectoralis minor (Elevate Rib Cage, assist in inhalation) External Intercostals (Elevate rib cage, assist in inhalation) Diaphragm (Prime mover of inhalation) All increase the size of the thoracic cavity.
