Chapter 1: Introduction to Anatomy and Physiology
1. Which of the following best describes anatomy?
A) The study of body function
B) The study of body structure
C) The study of chemical reactions in cells
D) The study of disease processes
Answer: B) The study of body structure
Explanation: Anatomy focuses on the physical structures of the body, including organs,
tissues, and cells.
2. Physiology is primarily concerned with:
A) The shape of organs
B) The function of body parts
C) The study of fossils
D) The classification of organisms
Answer: B) The function of body parts
Explanation: Physiology studies how organs and systems perform their functions, such
as how the heart pumps blood.
3. Homeostasis refers to:
A) Growth of tissues
B) Maintaining a stable internal environment
C) Reproduction of cells
D) Movement of muscles
,Answer: B) Maintaining a stable internal environment
Explanation: Homeostasis is the body's ability to regulate conditions like temperature,
pH, and electrolyte balance to stay stable.
4. Which level of organization is correctly ordered from simplest to most complex?
A) Tissue → Cell → Organ → Organ system → Organism
B) Cell → Tissue → Organ → Organ system → Organism
C) Organism → Organ system → Organ → Tissue → Cell
D) Cell → Organ → Tissue → Organ system → Organism
Answer: B) Cell → Tissue → Organ → Organ system → Organism
Explanation: Cells form tissues, tissues form organs, organs form systems, and systems
form an organism.
5. Which of the following is NOT a necessary life function?
A) Responsiveness
B) Growth
C) Reproduction
D) Color perception
Answer: D) Color perception
Explanation: While sensory functions like color perception are useful, they are not
essential for survival.
Chapter 2: The Chemical Level of Organization
6. Which subatomic particle has a positive charge?
A) Electron
B) Neutron
C) Proton
D) Ion
Answer: C) Proton
Explanation: Protons are positively charged, neutrons are neutral, and electrons are
negatively charged.
7. The basic unit of matter is called a:
A) Molecule
B) Atom
C) Ion
D) Element
, Answer: B) Atom
Explanation: Atoms are the smallest units of matter that retain the properties of an
element.
8. Which type of bond involves the transfer of electrons?
A) Covalent
B) Ionic
C) Hydrogen
D) Metallic
Answer: B) Ionic
Explanation: Ionic bonds form when electrons are transferred from one atom to another,
creating charged ions.
9. Water is a polar molecule. This means:
A) It has a uniform distribution of charge
B) It has no charge
C) It has partial positive and negative charges
D) It repels other polar molecules
Answer: C) It has partial positive and negative charges
Explanation: The oxygen end is slightly negative, and the hydrogen end is slightly
positive, allowing hydrogen bonding.
10. Which of the following is a carbohydrate?
A) Lipid
B) Glucose
C) Protein
D) Nucleotide
Answer: B) Glucose
Explanation: Glucose is a simple sugar and a key carbohydrate used for energy.
11. Lipids are primarily:
A) Water-soluble
B) Energy-storing molecules
C) Building blocks of DNA
D) Structural proteins
Answer: B) Energy-storing molecules
Explanation: Lipids store energy, form cell membranes, and act as signaling molecules.
12. Proteins are made of:
A) Nucleotides
B) Amino acids
