Health Care Fundamentals and Anatomy/Physiology Basics

Health Care Fundamentals and Anatomy/Physiology Basics tests whether you can describe the body as an organised whole and use precise anatomical language when you record findings.

Core rules

  • Levels of organisation run cell → tissue → organ → organ system → organism.
  • In the anatomical position the person stands erect, feet together, palms facing forward. Right and left always mean the patient's own right and left, never yours.
  • Directional pairs: superior/inferior, anterior/posterior, medial/lateral, proximal/distal (nearer or farther from the trunk), superficial/deep.
  • Cavities: cranial, vertebral, thoracic (pleural, pericardial, mediastinum) and abdominopelvic, separated by the diaphragm. Abdominal pain is described by quadrant (RUQ, LUQ, RLQ, LLQ).
  • Homeostasis runs on negative feedback; core temperature ≈37 °C, arterial pH 7.35–7.45, fasting glucose 70–110 mg/dL.
  • Adult resting vitals: pulse 60–100/min, respirations 12–20/min, BP 120/80 mmHg, SpO₂ ≥95 %, temperature 36.5–37.5 °C.

Systems in brief

Skeletal (206 bones, support, marrow), muscular (movement, heat), cardiovascular (transport), respiratory (gas exchange across the alveolar membrane), digestive (breakdown, absorption), urinary (filtration, fluid and acid–base balance), nervous (control), endocrine (hormones), integumentary (barrier, thermoregulation), lymphatic (immunity).

Worked example

A patient with lobar pneumonia has SpO₂ 88 % and a respiratory rate of 30/min. Reasoning: alveolar exudate thickens the respiratory membrane, so oxygen diffusion falls; chemoreceptors sense the hypoxia and drive the rate up. The low saturation is therefore an alveolar structure–function problem, not a heart problem, and the response is oxygen plus urgent medical review.

Traps that cost marks

  • Swapping proximal/distal with superior/inferior.
  • Writing left arm using your own left.
  • Quoting adult ranges for infants, whose pulse and respiratory rates are normally much higher.
  • Treating a single raised BP reading as a diagnosis.
