Study Notes
Male Reproductive System Components and Functions
- The scrotum is a sac of skin and muscle that provides a protective environment for the testes, regulating their temperature to facilitate sperm development.
Urinary and Reproductive Functions
- The urethra is a tube that carries both urine and semen out of the body, serving as a shared pathway for the urinary and reproductive systems.
Physiological Mechanisms
- Erections occur when the corpora cavernosa, two spongy tissues within the penis, become engorged with blood, causing the penis to expand and stiffen.
Blood Supply
- The internal pudendal artery is the primary blood vessel that supplies the penis, providing oxygen and nutrients necessary for its function.
Male Sex Organs
- The main male sex organs in the reproductive system are the testes, epididymis, vas deferens, prostate gland, urethra, and penis, which work together to produce, transport, and deliver sperm during ejaculation.
