✔ 最佳答案
1.salivary gland: To produce saliva for the digestion of starch and can turn the cut food by teeth into bolus.

2.bile duct: carry the bile juice produced by liver into the duodenum

3.spleen :to destroy old red blood cell.

4.pancreas: endocrine: to control the blood glucose level by secretion of insulin due to the beta cell. digestion: to secrete pancreatic juice to digest starch into maltose, lipid into fatty acid and glycerol, protein into small peptides and nucleic acid into nucleoside.

5.duodenum: when food comes form the stomach's pyloric sphincter, duodenum is stimulated so that more bile juice will be produced.
6.ileum:to complete the digest so that the digested food can be absorbed via osmosis, diffusion and active transport

7.colon: to absorb 6% of water after 94% of water is absorbed by ileum.

8.caecum:the same as human's appendix, it doesn't have any function.

9.appendix: no function in human but in herbivore it contains bacteria to digest cellulose

10.rectum: to store faeces.

11.xylem: for the transportation of water and mineral salt.

12.phloem: for the transportation of organic solvent such as sugar (sucrose).

13.cutile: to prevent water loss due to uncontrolled evaporation of water.

14.guard cell: to carry out photosynthesis due to the presence of chlorophyll.

15.hard palate :for the production of sound besides produced by vocal cord.

16.soft palate: it will raise and press against the nasal passage so that the food can go into oesophagus not nasal passage.

17.bolus : easy to swallow due to covered by a layer of mucus.

17.plottis: sorry, I only know what epiglottis is .

另外,請描述以下東西,和他們的分別(例如他們在那裡產生反應.)
1.ingestion: to intake the food from mouth.
2.digestion:to digest the food into simple and diffusible form.
3.absorption:to uptake the digested food into ileum by diffusion, osmosis and active transport.
4.assimilation:how to use the absorbed food/nutrient by our body cells.
5.egestion:to remove the undigested food in form of faeces.
請給清晰的回答!
還有,what things will occur if pleurqal membrane is broken? the person can't breathe anymore and the lungs will collapse, leading to pneumothorax(氣胸).
I hope you will find my answer helpful.
