10. The inner walls of the small intestine has many finger like out growth
called
2. Complete the following end products of digestion:
1.proteins

3. Fats
Answers
1)the digestion usually starts in the buccal cavity of the mouth of the human but after that it actually starts in the stomach
2) Stomach
3) Liver
4) The liver secretes bile, a digestive fluid; metabolizes proteins, carbohydrates, and fats; stores glycogen, vitamins, and other substances; synthesizes blood-clotting factors; removes wastes and toxic matter from the blood; regulates blood volume; and destroys old red blood cells.
5) The largest part of the GI tract is the colon or large intestine.
6)Incisors are the teeth that you use to bite into your food.
7) The main steps of nutrition in humans are ingestion, digestion, absorption, assimilation and egestion.
8) Baby teeth /Primary teeth/milk teeth
9)The rumen is the first compartment where ingested food containing cellulose is stored temporarily and later regurgitated to chew their cud.
10)Villi
2)I)The end product of protein digestion is amino acids. Once consumed, proteins are digested and broken down into amino acids by enzymes.
ii)The final product of carbohydrate digestion is primarily glucose along with some fructose, glucose, and galactose, while amino acids are the end products of protein digestion throughout the small intestines
iii)The complete digestion of one molecule of fat (a triglyceride) results in three fatty acid molecules and one glycerol molecule.
