20 questions
Question 1: The immune system's components include red blood cells, which are primarily responsible for fighting pathogens.
A. Yes
B. No
Explanation: The study materials state that white blood cells (leukocytes), antibodies, and lymphoid organs (e.g., lymph nodes, spleen, thymus, bone marrow) are components of the immune system. Red blood cells are not listed as an immune system component, nor are they described as primarily responsible for fighting pathogens.
Question 2: The male reproductive system produces male gametes and male sex hormones like testosterone.
A. Yes
B. No
Explanation: The study materials explicitly state that the functions of the Male Reproductive System include producing male gametes (sperm) and male sex hormones (e.g., testosterone).
Question 3: The endocrine system is primarily responsible for regulating immediate reflex actions.
A. Yes
B. No
Explanation: The endocrine system regulates long-term processes such as growth, metabolism, reproduction, and stress response by producing and secreting hormones. Immediate reflex actions are not listed as a primary function of the endocrine system.
Question 4: The lymphatic system is primarily responsible for regulating long-term processes such as growth and metabolism.
A. Yes
B. No
Explanation: The study materials state that the lymphatic system works closely with the cardiovascular system to return excess interstitial fluid, filters lymph, produces lymphocytes, and transports fats. It does not mention regulating long-term processes such as growth and metabolism; those functions are attributed to the endocrine system.
Question 5: The vestibular system is responsible for maintaining balance and coordinating head and eye movements.
A. Yes
B. No
Explanation: The study materials explicitly state that the vestibular system's functions include "maintaining balance, spatial orientation, and coordinating head and eye movements." It detects changes in head position and motion, sending signals to the brain that help stabilize vision and maintain posture.
