chapter 6

What is homeostasis and why is it important?

• Homeostasis refers to the movement of organisms from one habitat to another.

• Homeostasis is the ability of organisms to reproduce and grow.

• Homeostasis is the process of photosynthesis in plants.

• Homeostasis is the regulation of internal conditions in organisms, and it is important for survival and optimal functioning of biological processes.

Describe the levels of structural organization in the human body.

• Molecular, Cellular, Organ, Organism

• Chemical, Organ, Organ System, Organism

• Cell, Tissue, Organ, Organ System, Organism

• The levels of structural organization in the human body are: Chemical, Cellular, Tissue, Organ, Organ System, and Organism.

What are the major functions of a typical human cell?

• Cellular respiration, neurotransmitter release, skin regeneration, and fat storage.

• Energy production, protein synthesis, cell division, and cell communication.

• DNA replication, muscle contraction, sensory perception, and blood circulation.

• Nutrient absorption, waste elimination, hormone production, and immune response.

List the four primary types of tissues in the body.

• Epithelial, skeletal, adipose, lymphatic

• Epithelial, connective, muscle, nervous

• Connective, epithelial, cardiac, respiratory

• Muscle, nervous, dermal, endocrine

How does homeostasis relate to body temperature regulation?

• Homeostasis only affects heart rate and not temperature.

• Body temperature is regulated solely by diet and exercise.

• Homeostasis maintains stable body temperature through mechanisms like sweating and shivering.

• Homeostasis disrupts body temperature during sleep.

Identify the smallest unit of life in the human body.

• Organ

• Cell

• Tissue

• System

What role do epithelial tissues play in the body?

• Epithelial tissues protect, absorb, secrete, and sense.

• Epithelial tissues are responsible for muscle contraction.

• Epithelial tissues primarily store fat and energy.

• Epithelial tissues transport oxygen in the bloodstream.

Explain the difference between connective and epithelial tissues.

• Connective tissues support and bind, while epithelial tissues cover surfaces.

• Epithelial tissues support and bind, while connective tissues cover surfaces.

• Connective tissues are responsible for digestion, while epithelial tissues provide energy.

• Connective tissues are found only in the brain, while epithelial tissues are found in the heart.

What is the function of muscle tissue?

• The function of muscle tissue is to facilitate movement and maintain posture.

• To store energy for the body.

• To protect internal organs from injury.

• To produce hormones and enzymes.

Describe the role of nervous tissue in the body.

• Nervous tissue stores energy and nutrients in the body.

• Nervous tissue transmits signals, coordinates responses, and processes information in the body.

• Nervous tissue forms the protective outer layer of organs.

• Nervous tissue is responsible for producing hormones.
