Answers
Answer:
2,Artery
1,Aerobic respiration takes place in the mitochondria and requires oxygen and glucose, and produces carbon dioxide, water, and energy. ... This process requires oxygen and therefore following anaerobic respiration there is oxygen debt in the cell, as oxygen is needed to break down the lactic acid produced.
1)Left chamber
7,The four-chambered heart has a distinct advantage over simpler structures: It allows us to send our "dirty" blood to the cleaners-the lungs-and our "clean" blood to the rest of the body without having to mix the two. That system is very efficient
5,Emulsification is the process of breaking down the fat into smaller globules making it easy for the enzymes to act and digest the food . Emulsification of fats helps in digestion of fats into fatty acids and glycerol which an be easily absorbed by small intestine
Answer:
Oxidization of food materials in the body is known as respiration
