Introduction to Anatomy and Physiology Lesson 2.1 Study Questions Questions
Question 1 of 5
Which of the following is NOT found in the mediastinum?
Correct Answer: B
Rationale: The mediastinum, a central thoracic region, contains the heart, thymus, and trachea, but not lungs, which are in pleural cavities. Anatomically, this midline space organizes chest structures, excluding lateral lungs.
Question 2 of 5
The female reproductive system includes which body parts?
Correct Answer: B
Rationale: The female reproductive system includes ovaries, not testes (A, male), femur (C, bone), or thyroid (D, endocrine). Anatomically, ovaries produce eggs, central to female reproduction, confirming B.
Question 3 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 4 of 5
The lungs are situated within which body cavity?
Correct Answer: B
Rationale: The lungs reside in the thoracic cavity, within the chest, enclosed by the ribcage and diaphragm. The cranial cavity houses the brain, abdominal the stomach, pelvic the bladder, and spinal the spinal cord. Anatomically, the thoracic cavity's pleural subdivisions protect and support lung function breathing making B the correct choice, aligning with respiratory anatomy.
Question 5 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.
