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

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.

2. What is the role of the spleen in the lymphatic system?

Correct answer: A

Rationale: The spleen plays a crucial role in the lymphatic system by filtering blood, specifically removing old or damaged red blood cells. Additionally, the spleen produces lymphocytes, a type of white blood cell that plays a key role in the immune response by helping to fight off infections. Therefore, the correct answer is A, as the spleen is primarily involved in blood filtration and the production of lymphocytes rather than storing vitamins or regulating body temperature.

3. Which of the following is not part of the axial skeletal system?

Correct answer: D

Rationale: The correct answer is D, the radius. The axial skeleton comprises bones located along the central axis of the body. It includes the skull, ribs, breastbone (sternum), vertebrae, and sacrum. The radius, on the other hand, is a bone of the forearm, part of the appendicular skeleton. The appendicular skeleton consists of the bones of the limbs and their girdles, not the central axial bones.

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

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.

5. What is the function of hemoglobin in red blood cells?

Correct answer: B

Rationale: The correct answer is B: 'To transport oxygen.' Hemoglobin in red blood cells plays a crucial role in transporting oxygen. It binds to oxygen in the lungs and carries it to the body's tissues and organs for cellular respiration. Choices A, C, and D are incorrect because hemoglobin's primary function is to bind and transport oxygen, not to fight infections, carry carbon dioxide, or store oxygen.
