Which system in the human body is responsible for transporting blood throughout the body?

  • A. Digestive System
  • B. Circulatory System
  • C. Nervous System
  • D. Respiratory System
Correct Answer: B

Rationale: The circulatory system is responsible for transporting blood throughout the body. It consists of the heart, blood vessels, and blood. The heart pumps oxygenated blood from the lungs to the rest of the body and returns deoxygenated blood back to the lungs for oxygenation. The blood vessels, including arteries, veins, and capillaries, help in the transport of blood to all parts of the body, delivering oxygen and nutrients while removing waste products. The digestive system is responsible for processing food, the nervous system for transmitting signals, and the respiratory system for exchanging gases.

Which structure regulates the transport of substances in and out of a cell?

  • A. Nuclear membrane.
  • B. Cell’s cytoplasm.
  • C. Cell membrane.
  • D. Cell wall.
Correct Answer: C

Rationale:

Where do spermatozoa develop in men?

  • A. Seminiferous tubules
  • B. Vas deferens
  • C. Ejaculatory ducts
  • D. Bulbourethral glands
Correct Answer: A

Rationale: Spermatozoa develop within the seminiferous tubules of each testis. These tubules are responsible for the production of sperm through a process called spermatogenesis. While the vas deferens, ejaculatory ducts, and bulbourethral glands play essential roles in the transport and release of sperm, they are not involved in the actual development of sperm.

You have been given a sample of tissue that has open spaces partially filled by an assemblage of needle-like structures. What is the tissue?

  • A. Spongy bone
  • B. Compact bone
  • C. Cartilage
  • D. Adipose tissue
Correct Answer: A

Rationale: The correct answer is A: Spongy bone. Spongy bone tissue has open spaces partially filled by needle-like structures known as trabeculae. This arrangement gives spongy bone its characteristic appearance and provides structural support while reducing the tissue's density. Compact bone, on the other hand, is dense and solid, lacking the open spaces seen in spongy bone. Cartilage is a flexible connective tissue without needle-like structures, and adipose tissue is predominantly composed of fat cells, not needle-like structures.

Which structure controls the hormones secreted by the pituitary gland?

  • A. hypothalamus
  • B. adrenal gland
  • C. testes
  • D. pancreas
Correct Answer: A

Rationale: The correct answer is the hypothalamus. The hypothalamus is a region of the brain located below the thalamus that plays a crucial role in controlling the pituitary gland. It releases hormones that either stimulate or inhibit hormone production in the pituitary gland, thus regulating various bodily functions. The adrenal gland, testes, and pancreas do not directly control the hormones secreted by the pituitary gland.

Which type of cell division occurs in the gonads?

  • A. Mitosis
  • B. Meiosis
  • C. Binary fission
  • D. Asexual division
Correct Answer: B

Rationale: Meiosis is the type of cell division that occurs in the gonads. During meiosis, cells undergo two rounds of division resulting in the formation of gametes (sperm and egg cells) with half the number of chromosomes. This process is vital for sexual reproduction and genetic diversity.
