Human Body Systems — UPSSSC PET Preparation
This question tests your understanding of Human Body Systems, a key topic in the UPSSSC PET General Knowledge section. The detailed solution above uses a step-by-step approach to show the reasoning, and where available, a shortcut that helps you solve similar questions in under 90 seconds during the actual exam.
This topic covers the systems of the human body: the circulatory, respiratory, excretory, nervous, endocrine, skeletal and muscular systems, the sense organs, and important facts about blood, blood groups, bones and hormones. Common questions ask about the number of bones in an adult (206), the largest and smallest bones (the femur and the stapes), the universal donor blood group (O negative), which gland is called the 'master gland' (the pituitary), and which hormone controls blood sugar (insulin). The functional unit of the kidney is the nephron. Practise the human body systems questions below, written in the style of the general awareness sections of exams such as SSC, banking, railways, CUET GAT, MAH CET and CLAT. Each question comes with a detailed explanation that adds related facts, so every question helps you revise more than one point.
