What does the respiration process involve?

Answer 1

The respiratory system requires breathing. Each breath is involuntary and achieved through the cooperative use of a variety of muscles near the lungs. These muscles include the following:

• Diaphragm: The diaphragm is located above the ribs and consists of a thin sheet of muscles. It assists in breathing by pulling and pushing the lungs up and down to expand or contract.
• Intercostal muscles: These muscles lie between the ribs and help with the mechanism of breathing, including pushing and pulling the lungs to expand or decrease their capacity.
• Abdominal muscles: The abdominal area assists people breathe when under pressure, such as running or stress. They assist the diaphragm and intercostal muscles to move much faster and with greater force.

During breathing, several connected events occur. As air enters through the mouth or nose, the lungs expand with the help of the diaphragm, intercostal and abdominal muscles. The air is cleaned in the nose through tiny hairs, and warmed up in both the nose and the mouth. The air travels down the throat and through the "trachea" The trachea funnels the air into one of the two lungs

Answer 2

The respiration process involves the exchange of oxygen and carbon dioxide between the body and the external environment. It includes breathing in (inhalation) and breathing out (exhalation), where oxygen is taken in and carbon dioxide is expelled. This process occurs in the lungs and is necessary for cells to produce energy.

Answer 3

Carbohydrates such as glucose are broken down to carbon dioxide and water. Oxygen is consumed.
