Respiration (physiology)

Respiration is the process by which an organism obtains energy by reacting oxygen with glucose to give water, carbon dioxide and ATP (energy). Respiration is commonly confused with breathing, but they are not the same. Respiration takes place on a cellular level whereas breathing is on a different level. Respiration takes place in the mitochondria of the cells and provide the cells with energy.

Respiration also takes place in plants, where they respire the products of photosynthesis - oxygen and glucose to give energy, water and carbon dioxide.

Reaction of Respiration

Aerobic Respiration

Word Reaction:

glucose + oxygen ---> water vapour + carbon dioxide + energy (2380 kJ)

Anaerobic Respiration

Word Reaction:

glucose ---> alcohol + carbon dioxide + water vapour + energy (118 KJ)

As you can see, Anaerobic respiration releases much less energy because the alcohol released still contains great deal of energy.

We inhale oxygen and exhale carbon dioxide

There are several ways to dichotomize the physiology of respiration:

By species

*Aquatic respiration
*Buccal pumping

By mechanism

*Respiration organ
*Gas exchange
*Arterial blood gas
*Control of respiration
*Apnea

By experiments

*Huff and puff apparatus
*Respirometer
*SIFT-MS selected ion flow tube mass spectrometry
*Bell jar model lung

By disorders and emergencies

*Sudden Infant Death Syndrome
*Myasthenia gravis
*Asthma
*Drowning
*Choking
*Dyspnea
*Anaphylaxis
*Pneumonia
*Severe acute respiratory syndrome
*Aspiration (medicine) - Pulmonary edema

By medication

*Bronchodilator
*Asthma medication

By intensive care and emergency medicine

*CPR
*Mechanical ventilation
*Intubation
*Iron lung
*Intensive care medicine
*Liquid breathing
*ECMO
