1. Q: What is homeostasis?
A: Homeostasis is the maintenance of a stable internal environment
despite external changes.
2. Q: What are the four primary types of tissue in the human body?
A: Epithelial, connective, muscle, and nervous tissue.
3. Q: What is the function of neurons?
A: Neurons transmit electrical signals throughout the body to
communicate information.
4. Q: Describe the role of the hypothalamus.
A: The hypothalamus regulates many physiological processes, including
temperature, thirst, and hormone release.
5. Q: What are action potentials?
A: Action potentials are rapid, temporary changes in membrane
potential that propagate along neurons.
6. Q: How do muscles contract?
A: Muscle contraction occurs through the sliding filament theory, where
actin and myosin filaments slide past each other.
7. Q: What is the function of red blood cells?
A: Red blood cells transport oxygen from the lungs to the tissues and
