Which type of cell secretes antibodies?

  • A. bacterial cell
  • B. viral cell
  • C. lymph cell
  • D. plasma cells
Correct Answer: D

Rationale: Plasma cells are a type of white blood cell specialized in producing and secreting antibodies. Antibodies, also known as immunoglobulins, are vital components of the immune system that help recognize and neutralize pathogens. When the body encounters an antigen, plasma cells are activated to produce and secrete antibodies specific to that antigen. These antibodies bind to the pathogen, marking it for destruction by other immune cells. Therefore, plasma cells are the correct answer as they are specifically designed to produce and secrete antibodies to fight infections.

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.
