1. What is the function of amylase?

• A. Breaking down starch
• B. Digesting fat
• C. Breaking down protein
• D. Absorbing water

Correct answer: A

Rationale: The correct answer is A: Breaking down starch. Amylase is an enzyme that specifically functions to break down starch into smaller sugar molecules such as maltose and glucose. This process is essential for the digestion and absorption of carbohydrates in the body. Choices B, C, and D are incorrect because amylase does not digest fat, break down protein, or absorb water; its primary function lies in starch digestion.

2. Which of the following are considered normal values for the measure of a person’s pulse and blood pressure?

• A. 55 beats per minute and 75 over 60 mm Hg
• B. 72 beats per minute and 120 over 80 mm Hg
• C. 100 beats per minute and 140 over 100 mm Hg
• D. 160 beats per minute and 100 over 70 mm Hg

Correct answer: B

Rationale: Normal values for pulse rate typically range between 60 to 100 beats per minute, while normal blood pressure values are usually around 120/80 mm Hg. Option B falls within these normal ranges for both pulse rate and blood pressure, making it the correct choice. Choices A, C, and D have either pulse rate, blood pressure, or both values outside the normal ranges, making them incorrect.

3. Which structure is part of both the male reproductive system and the urinary system?

• A. Bladder
• B. Urethra
• C. Prostate
• D. Seminal Vesicle

Correct answer: B

Rationale: The urethra is the correct answer because it is a tube that is part of both the male reproductive system and the urinary system. It allows urine to pass out of the body as part of the urinary system and also transports semen as part of the male reproductive system. The bladder (Choice A) is solely part of the urinary system, storing urine. The prostate (Choice C) is part of the male reproductive system, secreting fluids that nourish and protect sperm. The seminal vesicle (Choice D) is also part of the male reproductive system, producing seminal fluid that mixes with sperm to form semen.

4. What is the most visible part of the ear called?

• A. Cochlea
• B. Pinna
• C. Ear canal
• D. Organ of Corti

Correct answer: B

Rationale: The pinna, also known as the auricle, is the most visible part of the ear. It is responsible for capturing sound waves and directing them into the ear canal, where the process of hearing begins. The other structures mentioned, such as the cochlea, ear canal, and organ of Corti, play crucial roles in the auditory system but are not the most visible parts of the ear. The cochlea is a spiral-shaped cavity responsible for converting sound vibrations into neural signals. The ear canal is a tube that connects the outer ear to the eardrum. The organ of Corti is the actual sensory organ of hearing located in the cochlea.

5. Which part of the brain is most posterior?

• A. Frontal lobe
• B. Parietal lobe
• C. Temporal lobe
• D. Occipital lobe

Correct answer: D

Rationale: The occipital lobe is located at the most posterior part of the brain, towards the back of the head. It is primarily responsible for processing visual information from the eyes and plays a crucial role in vision-related functions. The frontal lobe (Choice A) is located at the front of the brain and is responsible for functions such as reasoning and planning. The parietal lobe (Choice B) is located in the middle part of the brain and plays a role in sensory information processing. The temporal lobe (Choice C) is located on the sides of the brain and is involved in processing auditory information and memory. Therefore, the occipital lobe (Choice D) is the correct answer as it is the most posterior region of the brain.
