What is the normal body temperature of a human?

Last Updated: 26 Jun 2026

What is the normal body temperature of a human? This question examines a fundamental concept of human anatomy, physiology, health, nutrition, disease, or body regulation that frequently appears in SSC CGL General Science. The human body works through coordinated organ systems. Restate the question in your own words, predict the answer before checking the options, and confirm that the explanation and correct-option field both point to 37 degree C.

A35 degree C

B37 degree C

C39 degree C

D41 degree C

Correct Answer: 37 degree CYour Answer: B

Explanation

Therefore option B, 37 degree C, is factually consistent with the stem, the marked correct index, and the explanation.✅ Correct Answer: B — 37 degree C The normal human body temperature is 37°C (98.6°F). This temperature is tightly regulated by the Hypothalamus. At this temperature, all enzyme-based biochemical reactions in the body function optimally. Any significant deviation from this temperature affects bodily functions. 35°C — Temperature below 36°C indicates Hypothermia (dangerously low body temperature); organs begin to fail. 39°C — Temperature above 38°C indicates Fever (Pyrexia); the body is fighting an infection. 41°C — Temperature at 41°C is Hyperpyrexia (extreme fever); extremely dangerous, can cause brain damage and organ failure. 📝 Important Note: Normal body temperature = 37°C (98.6°F). Hypothalamus regulates body temperature. Body temperature is lowest in early morning and highest in late afternoon.

Important Notes

rd is 37 degree C, corresponding to option B. The answer field, correct index, and both explanations must remain aligned.
Read the complete stem and identify the exact demand: organ, gland, hormone, cell, tissue, nutrient, enzyme, pathogen, vector, deficiency disease, body fluid, or physiological function.
35 degree C, 39 degree C, 41 degree C are eliminated here because none satisfies the precise requirement of the stem. Practising the reason for each rejection is more reliable than memorising only the correct choice.
Numerical biological facts often vary with age, sex, body size, and reference range. Use the standard approximate value expected in school-level competitive examinations and retain its unit.

FAQ

SSC CGL Human Body FAQs

Common questions and clear answers for this topic.

Which body systems are most important for SSC CGL preparation?

The digestive, circulatory, nervous, and skeletal systems appear most frequently, along with sensory organs and basic endocrine functions.

How many bones are there in the human body, and is this commonly asked?

Yes, the human body has 206 bones, and questions about the largest, smallest, and total bone count appear fairly often.

What kind of blood-related questions come up in SSC CGL?

Questions usually cover blood group compatibility, the role of platelets in clotting, and basic facts about blood pressure and heart function.

Do I need detailed biochemistry knowledge for the human body section?

No, most questions focus on what each organ does and why, rather than the detailed biochemical processes behind it.

How can I retain human body facts more effectively for the exam?

Linking facts to real-life observations, like why pulse is checked at the wrist, makes them easier to recall than memorizing textbook lines.
