Your image lists these Integrative Physiology topics:
  1. Skin
  2. Temperature regulation and acclimatization
  3. Exercise and sports physiology
  4. Aviation and space physiology
  5. Acid-base homeostasis
  6. Body-fluid volume homeostasis
  7. Growth, development, stress and ageing
  8. Nutrition and obesity
  9. Yoga and meditation
For the current RGUHS Phase I blueprint, Integrated Physiology is part of Physiology Paper II and is allocated about 7 marks. This means prepare it mainly as short-answer questions, short notes, clinical application questions, and case-based MCQs, rather than expecting a long essay every time. The blueprint is indicative, so marks and exact questions can vary. RGUHS 2025 blueprint

Highest-yield questions

A. Must prepare first

  1. Describe regulation of body temperature. Add the mechanism of fever.
    • Thermoregulatory centre, heat production, heat loss, pyrexia.

    • Sweating, salt conservation, plasma-volume changes, heat exhaustion and heat stroke.
  3. Explain acclimatization to cold and physiological responses to cold exposure.
    • Vasoconstriction, shivering, non-shivering thermogenesis.
  4. Classify acid-base disorders. Explain respiratory and renal compensation in metabolic acidosis.
    • Very important clinical application.
  5. Describe the mechanism of compensation in respiratory acidosis and respiratory alkalosis.

Likely case-based MCQs

Prepare these as they fit the current RGUHS case-scenario MCQ pattern:
  • A patient with vomiting: identify acid-base disorder and expected compensation.
  • A patient with diarrhea: metabolic acidosis, dehydration and ORS basis.
  • A patient with panic-induced hyperventilation: respiratory alkalosis.
  • A marathon runner with profuse sweating: fluid loss, electrolyte changes and thermoregulation.
  • A worker exposed to hot climate with confusion and very high temperature: heat stroke.
  • A trekker at high altitude with headache and breathlessness: acute mountain sickness and acclimatization.
  • An obese adult: calculate BMI and identify health risks.
  • An athlete: identify changes in heart rate, cardiac output, ventilation and oxygen consumption during exercise.
  • A scuba diver with joint pain after rapid ascent: decompression sickness.
  • A person practising yoga regularly: identify effects on autonomic activity, heart rate and stress response.

Best 7-mark revision priority

If time is limited, revise in this order:
  1. Acid-base disorders and compensation
  2. Thermoregulation, fever, heat acclimatization, heat stroke
  3. Body-fluid balance, dehydration, ORS, RAAS and ADH
  4. Exercise physiology and training effects
  5. High-altitude physiology and acclimatization
  6. Obesity, BMI, appetite regulation
  7. Yoga, meditation, stress and ageing
Do not depend only on Integrative Physiology for scoring because it has a small blueprint share. Focus first on CNS, endocrine, reproductive physiology and special senses, then use these topics to secure the integrated-physiology marks.

Give only most important questions which are asked in the exam

  1. Explain regulation of body temperature. Add a note on fever.
  2. Describe acclimatization to hot environment and heat stroke.
  3. Describe the physiological changes during exercise.
  4. Explain acid-base balance and compensation in metabolic acidosis.
  5. Describe body-fluid compartments and regulation of ECF volume.
  6. Write a short note on dehydration and ORS.
  7. Explain high-altitude acclimatization and acute mountain sickness.
  8. Describe the role of RAAS, ADH and ANP in body-fluid homeostasis.
  9. Define BMI. Classify obesity and write its physiological consequences.
  10. Write a short note on yoga and meditation and their physiological effects.
