SET 2026 TESTED QUESTIONS AND
CORRECT SOLUTIONS
◉ Physiology. Answer: - The study of function of the body parts
- Examines how organs and body systems function under normal
circumstances as well as how their functioning may be altered via
medication or disease
◉ Major Levels of Organization of the Human Body. Answer: - Atom
- Molecule
- Macromolecule
- Organelle
- Cell
- Tissues
- Organ
- Organ System
- Organism
◉ Examples of Levels of Organization. Answer: - Atom: Na+ and K+ in
the sodium-potassium pump
- Molecule: CO2 as byproduct of cellular respiration
- Macromolecule: carbohydrates, proteins, lipids, nucleic acids
- Organelle: mitochondria
,- Cell: RBC

◉ Integumentary System. Answer: - Includes hair, skin and associated
glands, toe/finger nails
- Provides protection
- Regulates body temperature
- Site of cutaneous receptors and some glands
- Synthesizes vitamin D
- Prevents water loss
◉ Skeletal System. Answer: - Includes upper and lower limb bones,
joints, sacrum, pelvis, vertebrae, cartilage, rib, sternum, skull
- Provides support and protection
- Site of hemopoiesis (blood cell production)
- Stores calcium and phosphorus

- Responsible for consciousness, intelligence, and memory
◉ Endocrine System. Answer: - Includes hypothalamus, pineal gland,
pituitary gland, thyroid gland, parathyroid glands, thymus, adrenal
glands, pancreas, kidneys, testes (male), and ovaries (female)
