what
well what happens is the repiration is external
Internal Respiration: Is changing food (glucose) into energy. External Respiration: Is breathing in and out.
external/ internal intercostals
Breathing is an internal force, controlled by the diaphragm and other muscles in the respiratory system. It is a vital process that brings oxygen into the body and removes carbon dioxide, essential for sustaining life.
external intercostals and the diaphragm
External nares ( Nostrils) are the openings formed by the external nose that open into the nasal cavity.
The external inertial respiration refers to breathing, while the cellular respiration refers to respiration between the cells.
The diaphragm and external intercostal muscles are primarily involved in changing the thoracic volume during breathing. The diaphragm contracts during inhalation to increase thoracic volume, while the external intercostal muscles help lift and expand the rib cage.
The diaphragm, the external intercostal and the interchondral portion of the internal intercostal muscles are the main muscles that control breathing. Other muscles are sometimes used, but only if the person has a breathing disorder or if the body needs energy very quickly.
External respiration refers to the act of mechanically pulling air into the lungs via breathing. Internal respiration is the exchange of gasses from blood to tissue and vice versa.
During external respiration, carbon dioxide is released from the body by diffusing from the blood into the alveoli in the lungs. It is then exhaled out of the body during the process of breathing.
