1. Physiology is best defined as the _____.
A. Study of all living things
B. Study of the bodily functions of living things
C. Study of human relationships
D. Maintenance of body temperature
E. Maintenance of physical fitness
Answer: b
Physiology is the branch of biology that deals with the functions and mechanisms
occurring in living organisms. It explains how systems, organs, cells, and biomolecules
carry out the chemical or physical functions they have in a living system.

Learning objectives: huph.sher.16.1.1 – describe the physiological approach to
explaining an event
2. What are the most basic building blocks of matter?
A. Tissue
B. Cells
C. Atoms
D. Bones
E. Amino acids
Answer: c
Atoms are the smallest units of matter that retain the properties of an element. All matter,
including the human body, is composed of atoms which combine to form molecules and
ultimately more complex structures like cells and tissues.

3. What are the four most common chemical elements in the human body?
A. Water, salt, protein, and fat
B. Iron, carbon, oxygen, and potassium
C. Blood, muscle, fat, and bone
D. Collagen, glucosamine, chondroitin, and cartilage
E. Oxygen, carbon, hydrogen, and nitrogen
Answer: e
These four elements make up over 96% of the human body by mass. They are
fundamental in forming biomolecules such as proteins, nucleic acids, and carbohydrates
essential to life.

4. Approximately how many red blood cells are replaced per minute in the human body
on average?
A. 150,000,000
B. 50,000,000
C. 5,000,000
D. 500,000
E. 5,000
Answer: a
The human body produces around 2–3 million red blood cells per second, totaling
roughly 150 million per minute. This constant regeneration supports oxygen transport
throughout the body.
