Human #male reproductive system class 10 | sexual reproduction | Biology : CBSE : NCERT X Science

Summary

This video explains the human male reproductive system, highlighting its key organs and their functions. The testes, located in the scrotum outside the body, produce sperm and the hormone testosterone. The prostate gland and seminal vesicles secrete fluids that nourish sperm. The sperm then travel through the vas deferens, combining with fluids, and enter the urethra, which is surrounded by the penis. The penis is responsible for depositing sperm into the female reproductive system during mating. The video also teases the next topic: the female reproductive system.

Takeaways

• 😀 The human male reproductive system consists of various organs, including the testes, scrotum, vas deferens, seminal vesicles, prostate gland, penis, and urethra.
• 😀 The two main functions of the male reproductive system are to produce germ cells (sperms), hormones, and accessory materials, and to deposit them into the female reproductive system.
• 😀 Germ cells or sperms are produced in the testes, which are located outside the abdominal cavity in the scrotum to maintain a lower temperature necessary for sperm production.
• 😀 The testes also produce the hormone testosterone, which regulates sperm formation and the development of secondary sexual characteristics during puberty.
• 😀 The prostate gland and seminal vesicles produce fluid secretions that provide nutrients to the sperm cells.
• 😀 Sperm cells travel through the vas deferens after being formed in the testes, where they mix with fluid secretions from the prostate gland and seminal vesicles.
• 😀 The vas deferens is a common duct for both sperm and urine, and it is connected to the urinary bladder.
• 😀 Sperm cells consist of genetic material and a long tail that aids in their movement toward the female germ cell.
• 😀 The sperm from the vas deferens enters the urethra, which is supported by the penis, the organ responsible for depositing sperm into the female reproductive system.
• 😀 During mating, the penis becomes hard and erect to facilitate the deposition of sperm into the female reproductive system.

Q & A

What are the main functions of the human male reproductive system?

The two main functions of the human male reproductive system are to produce male reproductive cells (sperms), hormones, and accessory materials, and to deposit these cells into the female reproductive system.

Why are the testes located outside the abdominal cavity?

The testes are located outside the abdominal cavity because sperm formation requires a temperature lower than the normal body temperature, and the scrotum provides this cooler environment.

What is the role of testosterone in the male reproductive system?

Testosterone is a male reproductive hormone that regulates sperm formation and is responsible for the development of secondary sexual characteristics during puberty.

What organs produce the fluids that support sperm cells?

The prostate gland and seminal vesicles produce fluid secretions that provide nutrients to the sperm cells and help them in their journey.

What is the function of the vas deferens in the male reproductive system?

The vas deferens is the tube through which sperm cells travel from the testes, where they are formed, to be joined with the fluid secretions from the prostate gland and seminal vesicles before entering the urethra.

What is the role of the urethra in the male reproductive system?

The urethra carries the sperm from the vas deferens and serves as the passageway for sperm to be deposited into the female reproductive system. It is also connected to the urinary bladder for urine transport.

How does the sperm cell move towards the female germ cell?

Sperm cells have a long tail that helps them move towards the female germ cell, which is critical for fertilization.

What happens to the penis during mating?

During mating, the penis becomes hard and erect, which enables it to deposit sperm into the female reproductive system.

What are seminal vesicles, and what do they contribute to the male reproductive system?

Seminal vesicles are glands that contribute fluid secretions to nourish sperm cells and help transport them during their journey from the testes to the female reproductive system.

How does sperm get the fluid it needs for its journey?

Sperm cells receive the necessary fluid from the prostate gland and seminal vesicles, which provide nutrients and aid in their transportation through the male reproductive system.
