Identify and describe the functions of the parts of the male reproductive system labeled A-I. Also explain spermatogenesis and the consequences of D being inside the body for reproduction.

Hapa ni majibu yaliyojazwa: a) A: Urethra Function: Transports semen and urine out of the body. B: Penis (Copulatory organ) Functions: • Copulation • Deposits sperm in the vagina C: Scrotum Explain the functions of C: • Protects the testes • To keep the testes at a temperature that is lower than body temperature / optimum temperature for sperm production, which is necessary to produce healthy sperm / so that healthy sperms can survive. D: Testis Produce: Sperm (By cell division called meiosis) and Testosterone (Male hormone) E: Epididymis Function: Part where sperm cells mature and are stored. F: Vas deferens (Sperm duct) Function: Transports sperm from the epididymis to the urethra. When cut: Vasectomy (Result: No sperm in semen) G: Seminal vesicle Function: Produces mucus that helps with the movement of sperm. H: Prostate gland Function: Produces an alkaline fluid that neutralizes the acidic vaginal fluid. Also, increases the motility of sperm. I: Cowper's gland Function: Produces a fluid that provides energy for the sperm cells. b) Spermatogenesis: • Under the influence of testosterone, diploid cells in the seminiferous tubules of the testes undergo meiosis to form haploid sperm cells. c) Explain the consequences for reproduction if part D is found inside the body. • Body temperature of 37°C is too high for optimal sperm production. • High temperature will lead to the formation of unhealthy sperm. • Reducing the chances of reproduction (fertilization). d) Draw a labeled diagram of a sperm cell • Tail - Used for swimming • Nucleus - Contains 23 chromosomes (haploid) • Mitochondria - Supplies energy for moving/swimming sperm • Acrosome - Contains enzymes to digest egg cell for fertilization Tuma swali linalofuata 📸
