Digestion is the breakdown of absorbed substances, Respiration, on the other hand, is the breakdown of food molecules with a release of energy.
You need oxygen to convert food into energy and this process is called cellular respiration
respiration
No, the esophagus only functions in digestion. The trachea is the passageway for respiration.
In heterotrophs digestion provide glucose molecules.These molecules are oxidized in respiration
Digestion and Respiration are alike in term of the fact that in both of them oxidation of food take place.
For example digestion and respiration.
Cellular respiration.
Pharynx (throat)
excretion, digestion, respiration
Sorry to disappoint you, but digestion DOES NOT connect photosynthesis to respiration. Photosynthesis and respiration comes from plants and animals, when the animal breathes out CO2, and they receive the oxygen when the plant inhales the CO2 and breathes out oxygen. That's it. And the cycle repeats just like that. NOTHING with digestion. Trust me.
in a cell different cell organelles do different functions(e.g. mitochondria-respiration) in the same way our body has different organs or different organ systems to do different functions(heart-respiration;digestive system-complete digestion and excretion of food)
The first step of the process is the digestion.
