Testis
Testis acts both as a sex organ and an endocrine gland. It consists of seminiferous tubules and stromal or interstitial tissue. Leydig cells produce a group of hormones called Androgen. For example, Testosterone.
Androgen stimulates spermatogenesis (formation of sperm), muscular growth, growth of facial and axillary hair, aggressiveness, and low pitch of voice. Facilitates maturation of the male accessory sex organs like epididymis, vas deferens, seminal vesicles, prostate gland, and urethra.
NCERT Notes for Class 11 Biology Chapter 19: Chemical Coordination and Integration
NCERT Notes Biology Class 11 Chapter 19 Chemical Coordination and Integration: The study of chemical coordination and Integration forms an important part of human physiology. Chemical coordination, integration, and regulations in the human body are carried out by special chemicals called hormones. Regulation, growth, and development of our organs, the endocrine glands, and cells are carried out by hormones.
Here, in Chapter 19 of Biology Class 11 NCERT Chemical Coordination and Integration, we will study the Human endocrine system, Hormones, and their mechanism of action.
