Why do We Respire?
We respire in order to release energy from the food we eat. The energy is used to power the processes that keep us alive.
How do We Respire?
The process of respiration is the uptake of oxygen from the environment and its use to produce energy in the cells of the body. The oxygen is taken into the body through the lungs and passed into the blood. The blood carries the oxygen to the cells where it is used to produce energy. The carbon dioxide produced by the cells is carried back to the lungs and exhaled.
Why do We Respire?
We respire in order to get oxygen into our bloodstream, which is then transported around our body to where it is needed. The oxygen is used to break down the food we eat into molecules that our cells can use for energy.
The Process of Respiration
The process of respiration is the process in which the body takes in oxygen from the air and uses it to break down food into a form that the body can use. The process of respiration also releases carbon dioxide from the body.
Respiration in Animals
Respiration is the process of exchanging gases between an organism and its environment. This occurs in the lungs in animals when oxygen is taken in and carbon dioxide is released.
