HESI A2 Anatomy and Physiology Practice Test
1. To which two systems does the urethra belong?
- A. Reproductive and endocrine
- B. Urinary and reproductive
- C. Endocrine and urinary
- D. Digestive and cardiovascular
Correct answer: B
Rationale: The urethra belongs to both the urinary and reproductive systems. In the urinary system, it functions as a passage for urine from the bladder to exit the body. In the reproductive system, it serves as a conduit for the expulsion of semen during ejaculation. Choice A is incorrect because the urethra is not part of the endocrine system. Choice C is also incorrect because the urethra is not primarily associated with the endocrine system. Choice D is incorrect as the urethra is not part of the digestive or cardiovascular systems.
2. Which is an anterior feature of the human head?
- A. The nose
- B. The ears
- C. The occipital lobe
- D. The temporal lobe
Correct answer: A
Rationale: The nose is an anterior feature of the human head, located in the frontal part of the face. It plays a vital role in the respiratory system by allowing air to enter and exit the body. Additionally, the nose contains olfactory receptors that enable the sense of smell. The ears, occipital lobe, and temporal lobe are not anterior features of the human head. The ears are located on the sides, the occipital lobe is at the back of the head, and the temporal lobe is on the sides and base of the cerebral cortex.
3. Which part of the respiratory system is in the upper respiratory tract?
- A. Bronchioles
- B. Alveolar ducts
- C. Alveoli
- D. None of the above
Correct answer: D
Rationale: The upper respiratory tract includes structures such as the nose, nasal cavity, pharynx, and larynx. These structures are responsible for filtering, warming, and humidifying the air. The lower respiratory tract comprises the trachea, bronchi, bronchioles, alveolar ducts, and alveoli. Bronchioles, alveolar ducts, and alveoli are all part of the lower respiratory system, involved in gas exchange. Therefore, the correct answer is 'None of the above' as none of the listed options are part of the upper respiratory tract.
4. How might an injury to the parietal lobe impact an individual?
- A. Breathing
- B. Attention
- C. Memory
- D. Perception
Correct answer: D
Rationale: An injury to the parietal lobe can impact an individual's perception, affecting their ability to interpret sensory information such as touch, spatial orientation, and recognizing objects. The parietal lobe is crucial for integrating sensory information and creating a coherent perception of the surrounding world. Damage to this area can lead to challenges with spatial awareness, object recognition, and accurate processing of sensory input. Choices A, B, and C are incorrect because breathing, attention, and memory are primarily associated with other brain regions such as the brainstem, frontal lobe, and temporal lobe respectively, not the parietal lobe.
5. In the human body, the ribs are ___________ to the lungs.
- A. medial
- B. superior
- C. anterior
- D. deep
Correct answer: C
Rationale: The correct answer is 'C: anterior.' The term 'anterior' refers to a position in front of or toward the front of the body. In this case, the ribs are positioned in front of the lungs when considering the anatomical position. The term 'medial' means toward the midline of the body, 'superior' means above or higher in position, and 'deep' refers to a position farther from the surface or external part. Therefore, the most appropriate choice is 'anterior' when describing the relationship between the ribs and the lungs.
