Anatomy and Physiology Practice Tests

These Grade 12 Science practice tests develop Anatomy and Physiology skills through body organization, tissues, homeostasis, movement, nervous and endocrine control, cardiovascular and respiratory function, digestion, excretion, immunity, and reproduction.

Skills covered

  • Using anatomical position, homeostasis, tissue types, organs, cell membranes, mitosis, mitochondria, and DNA concepts
  • Explaining bone remodeling, synovial joints, muscle contraction, neuromuscular junctions, skin, thermoregulation, cartilage, ligaments, and tendons
  • Analyzing neurons, membrane potential, synapses, reflexes, central and autonomic nervous systems, hormones, insulin, thyroid regulation, and cortisol feedback
  • Tracing blood flow, cardiac pacing, arteries, capillaries, hemoglobin, ventilation, alveolar exchange, lymphatic function, and antibodies
  • Applying digestion, liver function, nutrient absorption, nephron filtration, ADH, urinary regulation, fertilization, adaptive immunity, and memory

How to use these practice tests

For each question, identify the structure, trace the direction of movement or signaling, and explain how the structure supports the body system's function. Use the solutions to connect anatomy with homeostasis and physiological evidence.

Anatomical position provides a standard reference for describing locations and relationships in the human body.

2. QuestionMultiple choice

What is homeostasis?

Please select an answer first.

Correct answer: B

The correct answer is Maintenance of relatively stable internal conditions.

  1. Identify the body system or structure: Determine whether the question concerns anatomical organization, tissues, movement, control, transport, exchange, digestion, excretion, immunity, or reproduction.
  2. Apply the physiological principle: Homeostasis keeps variables such as temperature, blood glucose, and pH within functional ranges.
  3. Connect structure and function: The correct answer is Maintenance of relatively stable internal conditions.

Homeostasis keeps variables such as temperature, blood glucose, and pH within functional ranges.

3. QuestionMultiple choice

What is the primary function of epithelial tissue?

Please select an answer first.

Organs combine tissues in an organized structure that performs specific functions.

6. QuestionMultiple choice

What is negative feedback?

Please select an answer first.

Correct answer: B

The correct answer is A response that counteracts a change and moves a variable toward its set point.

  1. Identify the body system or structure: Determine whether the question concerns anatomical organization, tissues, movement, control, transport, exchange, digestion, excretion, immunity, or reproduction.
  2. Apply the physiological principle: Negative feedback stabilizes a regulated variable by reducing the original deviation.
  3. Connect structure and function: The correct answer is A response that counteracts a change and moves a variable toward its set point.

Negative feedback stabilizes a regulated variable by reducing the original deviation.

7. QuestionMultiple choice

What is the main function of the cell membrane?
