Respiration is very important role in biology. respiration is metabolic process which occurs in all organisms. it occurs within the cell of organization in these process, the energy is produced by the breakdown of glucose which is further used by cell to perform various functions.
The process of getting oxygen into the body and releasing carbon dioxide is called respiration. the energy is generate by breakdown of glucose molecules in all living cells of human body.
Oxygen is inhaled and is transported to various parts and use in the process of burning food particles.
The obtained glucose molecules are used for discharging energy in the form of ATP- Adenocine Triphosphate Molecules by the human body to fulfill essential process .
Respiration is assessed for quality, rhythm and rate.
The quality of person’s breathing is normally relaxed and silent. Respiratory distress can also cause nasal flaring, and the person often moves into tripod position.
Respiration normally has a regular rhythm . A regular rhythm means that the frequency of the respiration follows an even tempo with equal intervals between each respiration.
Respiration rates vary based on age. The normal resting respiratory rate for adults is 10-20 breathes per minute (OER#1). Children younger than one year normally have a respiratory rate of 30-60 breathes per minute, but by the age of ten, then normal rate is usually 18-30(OER#2).

The human body is made up of cells. The cells perform various activities such as nutrition, excretion, transport, and reproduction. They require energy to carry out these processes. This energy is provided by the food we eat.
The food has energy stored in it. This energy is liberated during respiration. The air we inhale contains oxygen. It is transported to different parts of the body and finally the cells. The oxygen in the cells assists in disintegrating the food. Consequently, energy is released. This process is known as cellular respiration.
The food is disintegrated in the cells into water and carbon dioxide with the help of oxygen. This process of breakdown of food in the presence of oxygen is known as aerobic respiration. When the food is disintegrated without the use of oxygen, it is known as anaerobic respiration. Energy is released upon the break down of food.
Respiration transforms energy stored in foods eaten by organism into energy that can be used for metabolic processes that sustain organism’s life.
Importance of the respiratory system is critical. Organisms can endure many days without food but cannot survive for more than few minutes if respiration does not takes place.
Muscle Cramps:-
The muscle cells also can anaerobically respire during cycling, running, heavy exercise. During exercise, the energy required is very high, however, the oxygen supplied to release the energy is restricted. To meet the energy demands, anaerobic respiration takes place. Cramps arise when the muscles respire anaerobically. After a massage, the blood circulation increases, thereby oxygen supply to the cells increases
