What is the function of thrombocytes?
- A. Blood clotting
- B. Oxygen transport
- C. Immune response
- D. Hormone production
Correct Answer: A
Rationale: Thrombocytes, also known as platelets, play a crucial role in blood clotting. When there is an injury or damage to a blood vessel, thrombocytes adhere to the site and form a plug to stop bleeding. This process is essential for wound healing and preventing excessive blood loss. Therefore, the correct function of thrombocytes is blood clotting.

Which type of muscle tissue is found in the heart?
- A. Smooth Muscle
- B. Skeletal Muscle
- C. Cardiac Muscle
- D. Elastic Muscle
Correct Answer: C
Rationale: The correct answer is C: Cardiac Muscle. Cardiac muscle tissue is specifically found in the heart and is responsible for its involuntary contractions to pump blood throughout the body. Cardiac muscle has unique features that enable synchronized contractions, essential for maintaining the heart's function, unlike skeletal and smooth muscles.
Which of the following are functions of the skeletal system? (Select the ONE that does not apply.)
- A. Supporting the body
- B. Hemopoiesis
- C. Conducting impulses
- D. Providing protection
Correct Answer: C
Rationale: The correct answer is C, 'Conducting impulses.' The skeletal system's primary functions include supporting the body to maintain posture and provide structure, facilitating movement, protecting internal organs, and producing blood cells through hemopoiesis. Conducting impulses is a function of the nervous system, not the skeletal system.
