i'm pretty suure.. it's digestion.
Well, metabolism is all chemical activity in an organism. usually this is put into four catagories ingestion, digestion, excretion, and respiration. So a red kangaroos matabolism is what nutrients it takes in, breaking substances into simpler substances, getting rid of waste materials, and breathing with its lungs.
Chemical digestion takes place in the stomach, the intestines, (saliva or enzymes) these parts of your body also use mechanical digestion.
The holozoic mode of nutrition is just the taking in of complex organic matter by animals. Hence, organisms undergoing this mode of feeding include humans, birds, whales, sharks, lions, elephants etc.
Ingestion takes place in the mouth.
Excretion is the elimination of waste from the body.
First it goes into the mouth,then it goes to the esophagus that takes the food from the mouth to the stomach,then it goes to the liver that puts in juices in the food,then it goes to the stomach,then it goes to the pancreas that produces several digested juices,then it goes to the small intestine that absorbs digested food,then it goes to the gall bladder that stores digested juices,finally it goes to the large intestine and it eliminates the waste.
All parts of the digestive system take part in digestion, except perhaps your oesophagus. Oesophagus is anatomical need of the body and there also the digestion of sugar takes place.
The human digestive system takes roughly 72 hours between ingestion and excretion, regardless of the specific food eaten. This is determined by the rate of peristaltic contractions pushing the material along.
let me tell all your something i want how digestion takes places.
Digestion first takes place in the mouth, then the stomach, and then in the small intestines.
