Chapter 1: Introduction to the Human Body
Question 1:
Which of the following is the correct order of organization from simplest to most complex in the
human body?
• A) Cell → Tissue → Organ → Organism
• B) Tissue → Cell → Organ → Organism
• C) Organ → Organism → Tissue → Cell
• D) Organ → Tissue → Cell → Organism
Answer: A) Cell → Tissue → Organ → Organism
Rationale: The human body is organized in a hierarchical manner. The cell is the basic unit of
life, which forms tissues (groups of similar cells), tissues combine to form organs, and organs
together make up the complete organism.
Question 2:
Which of the following best describes the function of homeostasis?
• A) Maintaining the body's temperature at all times
• B) Balancing the various systems of the body to maintain stable internal conditions
• C) Allowing the body to move and respond to external stimuli
• D) Regulating the rate of metabolism in cells
Answer: B) Balancing the various systems of the body to maintain stable internal
conditions
Rationale: Homeostasis refers to the body's ability to maintain a stable internal environment
despite external changes. This includes regulation of body temperature, pH balance, and the
concentration of various ions in the blood.

Question 3:
Which of the following elements is essential for the formation of hemoglobin, a protein in red
blood cells that carries oxygen?
• A) Oxygen
• B) Carbon
• C) Iron
• D) Calcium
Answer: C) Iron
Rationale: Iron is a key component of hemoglobin, which binds to oxygen in the lungs and
carries it through the bloodstream to various tissues in the body.
Question 4:
An ionic bond is formed when:
• A) Two atoms share electrons equally.
• B) One atom gives up an electron to another atom.
• C) Two atoms share electrons equally but have different electronegativities.
• D) Two atoms form a molecule with the same number of protons.
Answer: B) One atom gives up an electron to another atom.
Rationale: An ionic bond is formed when one atom loses an electron and another atom gains
that electron, leading to the formation of positively and negatively charged ions that are attracted
to each other.
Chapter 3: Cells and Tissues
Question 5:
Which of the following organelles is responsible for producing ATP, the primary energy
currency of the cell?
• A) Nucleus
• B) Mitochondrion
• C) Golgi apparatus
• D) Endoplasmic reticulum
Answer: B) Mitochondrion
Rationale: The mitochondrion is known as the "powerhouse" of the cell because it generates
ATP through cellular respiration, which is used by the cell for energy.
, Question 6:
Which type of tissue is responsible for transmitting electrical impulses throughout the body?
• A) Epithelial tissue
• B) Muscle tissue
• C) Nervous tissue
• D) Connective tissue
Answer: C) Nervous tissue
Rationale: Nervous tissue is specialized for transmitting electrical signals throughout the body,
enabling communication between different parts of the body, including the brain, spinal cord,
and peripheral nervous system.
Chapter 4: The Integumentary System
Question 7:
Which of the following is the primary function of melanin in the skin?
• A) To promote vitamin D production
• B) To protect the skin from UV radiation
• C) To produce sweat
• D) To regulate body temperature
Answer: B) To protect the skin from UV radiation
Rationale: Melanin is a pigment produced by skin cells called melanocytes. It absorbs and
scatters ultraviolet (UV) light, protecting the skin from UV damage that can lead to skin cancer.
Question 8:
Which layer of the skin is responsible for the production of new skin cells?
• A) Epidermis
• B) Dermis
• C) Hypodermis
• D) Stratum corneum
Answer: A) Epidermis
Rationale: The epidermis is the outermost layer of the skin, and within it, new skin cells are
constantly produced by the stratum basale (the deepest layer). These cells gradually move to the
surface, becoming keratinized as they reach the outer layers.
