Short questions
Q1. Name the primary reproductive organ in males. State its two major functions.
Q2. Why are the testes located in the scrotum outside the main abdominal cavity?
Q3. What is the role of the vas deferens in the male reproductive system?
Q4. What is semen? Name the reproductive cells present in it.
Q5.
During adolescence, a boy experiences changes such as a deeper voice, growth of facial hair, and development of other male secondary sexual characteristics.
Which hormone is mainly associated with these changes, and which organ produces it?
Q6.
A student is studying a labelled diagram of the male reproductive system and notices that several glands contribute fluids to the reproductive tract.
Why are these glandular secretions important for sperm during their journey through the reproductive system?
Q1. Describe the structure of the male reproductive system. Explain the functions of the testes, scrotum, vas deferens, urethra, and penis.
Q2. Explain the role of the accessory glands of the male reproductive system. Include the contribution of the seminal vesicles, prostate gland, and other relevant glands to the formation and functioning of semen.
Q3.Explain how sperm are produced and transported through the male reproductive system. Trace their journey from the site of production to the point where they leave the body.
Q1.
A doctor explains that the testes need to remain at a temperature slightly lower than the normal internal body temperature for proper sperm production.
a) Which structure helps maintain the suitable location and temperature of the testes?
b) Why is this temperature difference important for the male reproductive system?
Q2.
A person has normal sperm production in the testes, but a blockage develops in the tube that normally carries sperm towards the urethra.
a) Which reproductive structure may be affected?
b) How could such a blockage affect the movement of sperm?
Q3.
A student traces the movement of sperm through the male reproductive system and lists these structures:
Urethra
Testis
Vas deferens
Penis
