Question

Why are testes located outside the abdominal cavity . mention the endocrine and exocrine function of testes.

Answer 1

Answer:

• A pair of testes is located outside the abdominal cavity because spermatogenesis occurs at a temperature which is two to three degrees Celsius lower than the body temperature.

• Endocrine function : Synthesis of testosterone.

• Exocrine function : Production of sperm.

Explanation:

• Testes are located outside the abdominal cavity in a sac-like structure called the scrotum.
• The scrotal sac, by the mechanism of contraction and relaxation, can decrease or increase the radiation of heat energy from the scrotum thereby maintaining a temperature which is two to three degree Celsius lower than the body temperature.

• Thus an ambient temperature is maintained in the scrotum for sperm production.
• Testosterone is the male sex hormone responsible for development of male sexual characters and is produced by specialised cells called Leydig cells located in the testes.

Answer 2

Exocrine And Endocrine Organs

Explanation:

1. Its exocrine capacity is to deliver sperms. A couple of testis is put in a structure called as scrotum which is situated outside the stomach hole. Low temperature favors the development of sperms in the testicles by the procedure of spermatogenesis. Testicles likewise emit the hormone testosterone.  
2. The gonads make sperm. To do this, the temperature of the balls should be cooler than within the body  
3. The testicles are known as gonads.  
4. Their female partner are the ovaries.
5. The testicles have both exocrine and endocrine  capacities.  
6. The endocrine and exocrine items that originate from the testicles.
7. Endocrine capacity is the place the testosterone is delivered in the interstitial cells and  The exocrine capacity is the generation of spermatozoa which is created by the seminiferous tubules.  
8. The liver and pancreas are both exocrine and endocrine organs, they are exocrine organs since they emit items bile and pancreatic juice into the gastrointestinal tract through a progression of pipes, and endocrine since they discharge different substances straightforwardly into the circulatory system.  
9. The pancreas is 95% exocrine tissue and 1-2% endocrine tissue and the biggest exocrine organ.
10. The exocrine bit is a simply serous organ which produces stomach related chemicals that are discharged into the duodenum.
