1. Which of the following terms means close to the trunk of the body?

• A. Superficial
• B. Sagittal
• C. Proximal
• D. Distal

Correct answer: C

Rationale: The term 'proximal' means situated close to the point of attachment or the center of the body, such as close to the trunk. In anatomical terms, proximal is used to describe locations that are closer to the body's center or point of reference. 'Superficial' refers to something situated near the surface, 'sagittal' refers to a plane that divides the body into left and right portions, and 'distal' refers to a position away from the center or point of reference. Therefore, 'proximal' is the correct term to indicate a position close to the trunk of the body.

2. Which structure in the female reproductive system is responsible for producing eggs (ova)?

• A. Fallopian tubes
• B. Ovaries
• C. Uterus
• D. Vagina

Correct answer: B

Rationale: The correct answer is the ovaries. Ovaries are the primary reproductive organs in females responsible for producing eggs (ova) through a process known as oogenesis. Ova are released from the ovaries during ovulation and can be fertilized by sperm in the fallopian tubes. The uterus is where a fertilized egg implants and develops into a fetus, while the vagina serves as the birth canal and a site for sexual intercourse. Fallopian tubes are responsible for transporting eggs from the ovaries to the uterus and are the site where fertilization typically occurs. Therefore, while important for the reproductive process, the fallopian tubes do not produce eggs.

3. What is the primary mode of CO2 transport in the body?

• A. Bicarbonate
• B. Carbamino compounds
• C. None of these
• D. Plasma

Correct answer: A

Rationale: The correct answer is A: Bicarbonate. In the body, the primary mode of CO2 transport is as bicarbonate. Carbon dioxide is converted to bicarbonate in red blood cells as part of the bicarbonate buffer system, which helps maintain the pH balance in the blood. Bicarbonate is then transported in the plasma to the lungs where it is converted back to carbon dioxide for exhalation. While carbamino compounds also play a role in CO2 transport by binding to amino groups on proteins, bicarbonate is the main mode of transport for carbon dioxide in the body. Options B, C, and D are incorrect as they do not represent the primary mechanism of CO2 transport in the body.

4. Which of the following nutrients is essential for muscle growth and repair?

• A. Vitamin C
• B. Protein
• C. Carbohydrates
• D. Fat

Correct answer: B

Rationale: Protein is essential for muscle growth and repair as it provides the necessary building blocks (amino acids) for muscle tissue synthesis and repair. While vitamins and minerals are crucial for overall health, protein has a specific role in muscle development. Carbohydrates supply energy for workouts, and fats are important for general health but are less directly involved in muscle growth and repair compared to protein.

5. What is an electrically charged atom called?

• A. Ion
• B. Isotope
• C. Molecule
• D. Compound

Correct answer: A

Rationale: An ion is an atom that has gained or lost electrons, resulting in a positive or negative charge, making it electrically charged. This term specifically refers to atoms with a net electrical charge. Isotopes are atoms of the same element with different numbers of neutrons, not electrically charged. Molecules are formed when atoms bond together, but they are not necessarily charged. Compounds are substances composed of different elements bonded together, but they may not be electrically charged.
