1. Identify the INCORRECT function of the liver.

• A. Bile production to aid digestion.
• B. Synthesis of blood proteins, such as albumin.
• C. Storage of glucose for energy regulation.
• D. Filtration of waste products from the blood.

Correct answer: D

Rationale: A) Correct - The liver produces bile, which aids in the digestion and absorption of fats in the small intestine. B) Correct - The liver is responsible for synthesizing blood proteins, including albumin, which helps maintain osmotic pressure in the blood. C) Correct - The liver stores glucose in the form of glycogen and helps regulate blood sugar levels by releasing glucose when needed. D) Incorrect - The liver does not filter waste products from the blood. Instead, the kidneys are responsible for filtering waste products from the blood and excreting them in the form of urine.

2. Which of the following areas has the least amount of sweat glands?

• A. Back
• B. Palms
• C. Axilla
• D. Forehead

Correct answer: B

Rationale: The correct answer is B - Palms. The palms have the least amount of sweat glands compared to the other options listed. The back, axilla (armpits), and forehead are all areas with a higher concentration of sweat glands in the body. The palms have fewer sweat glands to minimize water loss and maintain a better grip for activities requiring precise and controlled movement. The back, axilla, and forehead have more sweat glands to assist in thermoregulation and cooling of the body, while the palms have fewer sweat glands for functional reasons related to grip and dexterity.

3. A person who carries a pathogen but does not exhibit any symptoms is considered:

• A. Asymptomatic carrier
• B. Opportunistic pathogen
• C. Nosocomial infection
• D. Vector-borne disease

Correct answer: A

Rationale: An asymptomatic carrier is a person who carries a pathogen, such as a virus or bacterium, without showing any symptoms of the infection. Despite lacking symptoms, asymptomatic carriers can still transmit the pathogen to others, potentially causing illness in those they contact. This term specifically pertains to infected individuals who do not manifest symptoms, distinguishing them from symptomatic carriers who do exhibit signs of the infection. Option A is the most fitting choice as it accurately characterizes a person carrying a pathogen without displaying symptoms. B) Opportunistic pathogen: This term describes pathogens that typically do not cause disease in healthy individuals but can be pathogenic in those with weakened immune systems. C) Nosocomial infection: This term refers to infections acquired in a hospital or healthcare facility. D) Vector-borne disease: This term relates to diseases transmitted to humans by vectors like mosquitoes or ticks.

4. What is the role of the pancreas in regulating blood sugar levels?

• A. To produce insulin only
• B. To produce both insulin and glucagon
• C. To store glucose
• D. To produce adrenaline

Correct answer: B

Rationale: The correct answer is B. The pancreas plays a crucial role in regulating blood sugar levels by producing both insulin and glucagon. Insulin helps lower blood sugar levels by promoting the uptake of glucose into cells, while glucagon raises blood sugar levels by stimulating the release of stored glucose into the bloodstream. Choice A is incorrect because the pancreas produces both insulin and glucagon. Choice C is incorrect because the pancreas does not store glucose; instead, it regulates glucose levels. Choice D is incorrect because adrenaline is produced by the adrenal glands, not the pancreas, and is not directly involved in regulating blood sugar levels.

5. Where does fertilization, the fusion of sperm and egg, typically occur in the female reproductive system?

• A. Ovary
• B. Fallopian tube
• C. Uterus
• D. Vagina

Correct answer: B

Rationale: Fertilization typically occurs in the fallopian tube. After ovulation, the egg is released from the ovary and travels through the fallopian tube, where it may encounter sperm for fertilization. The fallopian tube is the site where the sperm fertilizes the egg before the fertilized egg continues its journey towards the uterus for implantation. The ovary is where the egg is produced but not where fertilization occurs. The uterus is where the fertilized egg implants and develops into a fetus, not where fertilization takes place. The vagina is part of the birth canal and not the typical site for fertilization in the female reproductive system.
