1. To which system do the retinas belong?

• A. skeletal system
• B. nervous system
• C. lymphatic system
• D. circulatory system

Correct answer: B

Rationale: The retinas belong to the nervous system. The retina is a layer of tissue at the back of the eye responsible for detecting light and sending visual information to the brain through the optic nerve. This process is essential for vision, which is controlled by the nervous system. Choices A, C, and D are incorrect because the retinas have no association with the skeletal, lymphatic, or circulatory systems.

2. 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.

3. 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.

4. 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.

5. The anterior chamber of the eye lies between the ___________.

• A. iris and lens
• B. lens and retina
• C. cornea and iris
• D. retina and optic nerve

Correct answer: A

Rationale: The anterior chamber of the eye is the fluid-filled space located between the cornea and the iris in the front part of the eye. It contains aqueous humor and helps maintain intraocular pressure. The space between the iris and the lens is known as the anterior chamber, making option A, 'iris and lens,' the correct choice. Options B, C, and D are incorrect because they do not describe the correct anatomical location of the anterior chamber.
