What is being described when you are informed by the orthopedic surgeon that you have broken the middle region of the humerus?
- A. Epiphysis
- B. Articular cartilage
- C. Perichondrium
- D. Diaphysis
Correct Answer: D
Rationale: When the orthopedic surgeon informs you of a break in the middle region of the humerus, they are referring to the shaft or long portion of the bone, which is known as the diaphysis. The epiphysis is the end part of a long bone, while articular cartilage covers the ends of bones in joints. Perichondrium is a layer of connective tissue surrounding cartilage.
What is the name of the structure that prevents food from entering the airway?
- A. trachea
- B. esophagus
- C. diaphragm
- D. epiglottis
Correct Answer: D
Rationale: The structure that prevents food from entering the airway is the epiglottis. The epiglottis is a flap of cartilage located behind the tongue at the top of the larynx. During swallowing, the epiglottis covers the opening of the trachea, directing food and liquids to the esophagus instead of entering the airway. This mechanism ensures that food safely passes into the digestive system, avoiding any blockage of the respiratory pathway.
Which structure is part of both the male reproductive system and urinary system?
- A. Epididymis
- B. Ureter
- C. Testis
- D. Urethra
Correct Answer: D
Rationale: The correct answer is D, Urethra. The urethra is a structure shared by both the male reproductive and urinary systems. It serves as a passage for urine to exit the body and for semen during ejaculation. The Epididymis, Testis, and Ureter are not structures that are part of both systems. The Epididymis is involved in sperm maturation, the Testis is responsible for sperm production, and the Ureter transports urine from the kidneys to the bladder.
How much air does an adult inhale in an average breath?
- A. 500 mL
- B. 750 mL
- C. 1000 mL
- D. 1250 mL
Correct Answer: A
Rationale: An adult typically inhales around 500 mL of air in an average breath. This volume is known as tidal volume, representing the amount of air inspired or expired during normal breathing. Tidal volume plays a crucial role in efficient gas exchange in the lungs and maintaining adequate oxygen levels in the body. It is essential for proper respiratory function and ensuring the body receives the necessary oxygen for cellular respiration and overall metabolism.
