Introduction to Anatomy and Physiology Lesson 2.1 Study Questions Questions
Question 1 of 5
A disease that affects the entire body or involves several organ systems is referred to as:
Correct Answer: B
Rationale: Systemic diseases affect multiple systems (e.g., diabetes), not chronic (A, long-term), acute (C, short-term), or local (D, confined). Anatomical terminology clarifies disease scope, making B correct.
Question 2 of 5
The body system that provides an outer covering that protects the body from the external environment is:
Correct Answer: D
Rationale: The skin, or integumentary system, forms the outer barrier, shielding against pathogens and UV rays. Respiratory breathes, urinary excretes, cardiovascular circulates, and reproductive reproduces none cover externally. Anatomically, skin's layers (epidermis, dermis) regulate temperature and block harm, making D the protective system.
Question 3 of 5
Which hormone helps to maintain glucose homeostasis by stimulating liver cells to take up and remove additional glucose?
Correct Answer: A
Rationale: Insulin, lowers blood glucose by prompting liver uptake and storage as glycogen. Glucagon raises glucose, pancreas is an organ, response and starch are irrelevant. Anatomically, insulin's role in glucose homeostasis post-meal regulation prevents hyperglycemia, confirming A.
Question 4 of 5
Which of the following is the best definition of physiology?
Correct Answer: B
Rationale: Physiology explores the body's operational mechanisms how systems like circulation or respiration function in health. It's a dynamic science, revealing processes that sustain life, from nerve impulses to digestion. Nurses rely on this knowledge to support normal function like monitoring breathing rates distinguishing it from structural or cellular focuses. This broad inquiry into how' underpins medical interventions, ensuring treatments align with the body's natural workings for optimal outcomes.
Question 5 of 5
Which of the following is/are the contents of the dorsal body cavity?
Correct Answer: B
Rationale: The dorsal cavity, along the body's back, encases the brain and spinal cord, safeguarding the central nervous system. Unlike ventral organs, these structures govern thought and coordination. Nurses focus here for neurological issues like spinal injuries distinct from thoracic or abdominal contents. This cavity's protective role is key, housing the body's command center for effective health management.
