Human Physiology Previous Year NEET Questions Paper

Human Physiology Previous Year NEET Questions

Human Physiology Previous Year NEET Questions are essential for understanding exam trends and high-weightage topics. Practising these PYQs improves conceptual clarity. With solved answers and explanations, Human Physiology Previous Year NEET Questions help students strengthen NEET 2026 preparation and boost exam confidence.

Here are some Human Physiology PYQs:

Question 1:

Which of the following is not a component of the juxtaglomerular apparatus?
(1) Macula densa
(2) Juxtaglomerular cells
(3) Podocytes
(4) Extraglomerular mesangial cells

Correct Answer: (3) Podocytes

Explanation: The juxtaglomerular apparatus includes macula densa, JG cells and mesangial cells. Podocytes are part of Bowman's capsule involved in filtration, not regulation of $GFR$.

Question 2:

Which of the following statements is correct regarding the Bohr effect?
(1) An increase in pH decreases oxygen dissociation
(2) Increase in CO$_2$ increases the oxygen affinity of haemoglobin
(3) Decrease in pH increases oxygen dissociation from haemoglobin
(4) Oxygen binding increases CO$_2$ binding

Correct Answer: (3) Decrease in pH increases oxygen dissociation from haemoglobin

Explanation: Bohr effect states that an increase in $CO_2$ or a decrease in pH shifts the oxygen dissociation curve rightward, promoting release of $O_2$ from haemoglobin.

Question 3:

The Hering–Breuer reflex is initiated by:
(1) Chemoreceptors in the carotid body
(2) Stretch receptors in the lungs
(3) Baroreceptors in the aorta
(4) Respiratory centre in medulla

Correct Answer: (2) Stretch receptors in lungs

Explanation: Inflation of the lungs activates stretch receptors in bronchi/bronchioles. This inhibits inspiration via the vagus nerve to prevent over-expansion.

Question 4:

Which hormone is secreted by the posterior pituitary?
(1) Growth hormone
(2) Prolactin
(3) Oxytocin
(4) ACTH

Correct Answer: (3) Oxytocin

Explanation: Posterior pituitary stores and releases $ADH$ and oxytocin synthesised in the hypothalamus. Growth hormone and ACTH are anterior pituitary hormones.

Question 5:

During muscle contraction, calcium ions bind to:
(1) Actin
(2) Troponin
(3) Tropomyosin
(4) Myosin head

Correct Answer: (2) Troponin

Explanation: $Ca^{2+}$ binds to troponin, causing tropomyosin shift, exposing myosin binding sites on actin and allowing cross-bridge formation.

Question 6:

Which of the following blood vessels carries oxygenated blood?
(1) Pulmonary artery
(2) Vena cava
(3) Pulmonary vein
(4) Hepatic portal vein

Correct Answer: (3) Pulmonary vein

Explanation: Pulmonary vein carries oxygenated blood from the lungs to the left atrium. The pulmonary artery is an exception, carrying deoxygenated blood.

Question 7:

The filtration rate in the glomerulus depends on:
(1) Osmotic pressure of plasma proteins
(2) Hydrostatic pressure of glomerular capillaries
(3) Capsular hydrostatic pressure
(4) All of the above

Correct Answer: (4) All of the above

Explanation: Net filtration pressure is given by
$NFP = P_G - (P_B + \pi_G)$
where $P_G$ = glomerular pressure, $P_B$ = capsular pressure, $\pi_G$ = osmotic pressure. All influence $GFR$.

Human Physiology Previous Year NEET Questions Paper PDF

Solving previous year's questions is one of the best ways to understand the NEET 2026 exam pattern and difficulty level. The PDF below has been prepared for the Human Physiology NEET PYQs for organised study. It also helps students revise important topics quickly and boost their confidence before the exam.

NEET 2026 Human Physiology Syllabus (Class 11 Topics)

Human physiology covers all the important mechanisms that occur in the human body. This unit forms an important part of the NEET 2026 syllabus, helping students understand how systems function. It consists of 6 chapters, some of which are considered as do-or-die chapters for NEET. Practising Human Physiology NEET PYQs with solutions gives them a clear idea of the types of questions asked in the exam.

1. Breathing and Exchange of Gases - This chapter focuses on how we inhale oxygen, exhale carbon dioxide, and the mechanisms of breathing.
2. Body Fluids and Circulation - Circulation and composition of blood, and the functioning of the heart, are explained in this chapter.
3. Excretory Products and Their Elimination - How metabolic wastes are removed from the body is covered in the excretory products and their elimination chapter.
4. Locomotion and Movement - Different types of muscles, along with their structure and function, are discussed.
5. Neural Control and Coordination - This chapter explains how the nervous system controls and coordinates all the body's functions.
6. Chemical Coordination and Integration - The Chemical Coordination and Integration chapter focuses on hormones and endocrine glands.

Human Physiology Chapter-Wise Weightage PYQs Analysis

Having a thorough understanding of the weightage can help in effective NEET Biology preparation. It also allows students to identify the topics that are frequently asked in the NEET exam. Aspirants can also refer to the NEET biology chapter-wise weightage to compare the importance of other units. The table below shows the Human Physiology NEET PYQs chapter-wise weightage analysis based on the 5 years.

High‑Weightage Human Physiology Topics in NEET Exam

Knowing the important topics of each chapter makes preparation more focused. The table including all the important topics frequently asked in the Human Physiology NEET PYQs is provided below. By following the NEET preparation strategy, students can complete this important unit and secure 25-30 marks in the exam. Going through Human Physiology NEET PYQs with solutions also improves accuracy.

Tips to Practice NEET Human Physiology Questions Effectively

Some of the NEET 2026 preparation tips for studying human physiology units are mentioned below:

1. First, we have to understand the basic concepts of each organ.
2. Then, we have to focus on the functions and processes within each system.
3. After focusing, you have to relate those concepts to real-life examples, which will help us better understand the topics.
4. You have to use biology diagrams and flowcharts to visualise the complex processes involved.
5. Solve the NEET biology previous year's questions to understand the exam pattern better. So, reviewing the previous year’s NEET papers will help you to understand the type of human physiology NEET PYQ asks.
6. You can also check questions in NEET Biology to score 330+ marks for practice.
7. Take regular NEET Biology mock tests to check your preparation level.
