1. Which part of the brain is responsible for processing sensory information?

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

Correct answer: B

Rationale: The parietal lobe of the brain is responsible for processing sensory information such as touch, temperature, and pain. It integrates sensory information from various parts of the body, allowing an individual to perceive and respond to different stimuli. Functions like spatial awareness and perception of the body's position in space are also associated with the parietal lobe. The frontal lobe is responsible for functions like decision-making and personality. The occipital lobe is primarily involved in visual processing, and the temporal lobe plays a role in memory and auditory processing.

2. What is the primary role of the liver in the body?

• A. Producing insulin
• B. Detoxifying harmful substances
• C. Digesting food
• D. Storing energy

Correct answer: B

Rationale: The correct answer is B: Detoxifying harmful substances. While the liver does produce bile for digestion and stores nutrients like glycogen, its primary function is to filter and detoxify blood coming from the digestive tract before passing it to the rest of the body. Therefore, choices A, C, and D are incorrect. Producing insulin is mainly done by the pancreas, digesting food is primarily the role of the stomach and intestines, and storing energy is a function of various organs like muscles and fat cells.

3. Which type of blood cell is primarily responsible for fighting infections?

• A. Red blood cells
• B. White blood cells
• C. Platelets
• D. Plasma

Correct answer: B

Rationale: White blood cells, also known as leukocytes, play a crucial role in the immune system by primarily combating infections. These cells can identify and destroy pathogens, such as bacteria and viruses, helping the body defend against illnesses and maintain overall health. Red blood cells are responsible for oxygen transport, platelets aid in blood clotting, and plasma carries various components throughout the circulatory system, but none of these functions involve fighting infections like white blood cells do.

4. What is the primary function of the cardiovascular system?

• A. To pump blood throughout the body
• B. To deliver nutrients to tissues
• C. To regulate body temperature
• D. To protect the body from infection

Correct answer: A

Rationale: The primary function of the cardiovascular system is to pump blood throughout the body, ensuring that oxygen and nutrients are delivered to tissues while removing waste products. This circulation is essential for maintaining overall health and proper functioning of the body's cells and organs. Choices B, C, and D are incorrect because while the cardiovascular system does deliver nutrients to tissues indirectly by transporting them in the blood, regulating body temperature is primarily the role of the endocrine and nervous systems, and protecting the body from infection is the main function of the immune system.

5. Which muscle group is primarily responsible for extending the knee?

• A. Hamstrings
• B. Quadriceps
• C. Calves
• D. Glutes

Correct answer: B

Rationale: The quadriceps, a group of muscles located on the front of the thigh, are primarily responsible for extending the knee joint. When the quadriceps contract, they work to straighten the knee, allowing for actions like kicking or standing up from a seated position. The hamstrings (Choice A) are responsible for flexing the knee, the calves (Choice C) primarily work on plantar flexion at the ankle joint, and the glutes (Choice D) are mainly involved in hip extension.
