Which of the following best describes a function carried out by the circulatory system and the integumentary system working together?

  • A. Removal of excess heat from the body
  • B. Hormonal regulation of blood pressure
  • C. Transport of oxygen in the body
  • D. Production of red blood cells in the bone marrow
Correct Answer: A

Rationale: The correct answer is A: Removal of excess heat from the body. The circulatory system, which includes blood vessels and the heart, works with the integumentary system, which consists of the skin, to regulate body temperature by removing excess heat. This process involves blood vessels near the skin's surface dilating to release heat and constricting to conserve heat, a mechanism crucial for maintaining homeostasis. Option B, Hormonal regulation of blood pressure, is incorrect as it does not accurately describe the collaborative function of these systems in regulating body temperature. Option C, Transport of oxygen in the body, is incorrect as it focuses on a different function of the circulatory system. Option D, Production of red blood cells in the bone marrow, is incorrect as it pertains to the skeletal and hematopoietic systems, not the circulatory and integumentary systems working together to regulate body temperature.

Which of the following is NOT part of the circulatory system?

  • A. Kidneys
  • B. Heart
  • C. Blood
  • D. Blood vessels
Correct Answer: A

Rationale: The correct answer is A: Kidneys. The kidneys are part of the urinary system, responsible for filtering waste and maintaining fluid balance in the body. In the circulatory system, the heart pumps blood, blood carries oxygen and nutrients, and blood vessels transport blood throughout the body. Choices B, C, and D are all components of the circulatory system, making the kidneys the correct choice as it belongs to the urinary system.

What function do ribosomes serve within the cell?

  • A. Ribosomes are responsible for cell movement.
  • B. Ribosomes aid in protein synthesis.
  • C. Ribosomes help protect the cell from its environment.
  • D. Ribosomes have enzymes that help with digestion.
Correct Answer: B

Rationale: Ribosomes serve a crucial role in protein synthesis by translating mRNA into proteins. They are not involved in cell movement, protecting the cell from the environment, or aiding in digestion. Choice A is incorrect because ribosomes are not responsible for cell movement. Choice C is incorrect because ribosomes do not primarily protect the cell from its environment. Choice D is incorrect because ribosomes do not have enzymes that aid in digestion.

What type of immunity is acquired through vaccination?

  • A. Passive natural immunity
  • B. Active natural immunity
  • C. Active artificial immunity
  • D. Passive artificial immunity
Correct Answer: C

Rationale: The correct answer is C, Active artificial immunity. Vaccination introduces a weakened or inactive form of the pathogen to stimulate the immune system, leading to the development of immunity. Active artificial immunity is the result of deliberate exposure to an antigen, such as through vaccination, to produce an immune response. Passive immunity, like receiving pre-formed antibodies, does not involve the immune system's activation. Natural immunity is typically acquired through exposure to the pathogen itself, not through vaccination.

Which organelle provides energy for cellular functions?

  • A. Nucleus
  • B. Cell membrane
  • C. Mitochondria
  • D. Cytoplasm
Correct Answer: C

Rationale: The correct answer is C, Mitochondria. Mitochondria are often referred to as the powerhouse of the cell as they produce energy in the form of ATP through cellular respiration. This process is essential for various cellular functions, making mitochondria crucial for energy production within the cell. Choice A, Nucleus, is incorrect as the nucleus is responsible for housing the cell's genetic material and controlling cellular activities but not for energy production. Choice B, Cell membrane, is incorrect as it is primarily involved in maintaining cell integrity and regulating the passage of substances in and out of the cell, not in energy production. Choice D, Cytoplasm, is incorrect as it is the jelly-like substance that fills the cell and is the site of many metabolic pathways, but it is not the specific organelle responsible for energy production.

Which of the following describes a responsibility of the integumentary system?

  • A. Distributing vital substances, such as nutrients, throughout the body.
  • B. Blocking pathogens that cause disease.
  • C. Sending leaked fluids from the cardiovascular system back to the blood vessels.
  • D. Storing bodily hormones that influence gender traits.
Correct Answer: B

Rationale: The correct responsibility of the integumentary system is to act as a barrier that blocks pathogens from entering the body, thus helping to prevent diseases and infections. This function serves as the first line of defense for the body against external threats. Choices A, C, and D are incorrect. Choice A is a function of the circulatory system, not the integumentary system. Choice C relates to the lymphatic system, not the integumentary system. Choice D involves the endocrine system, not the integumentary system.
