Human Physiology MCQs

The topic Human Physiology will help you to understand the functions and mechanisms of a human body involving organs, cells, blood, nerves, etc which help us to interact with our surroundings and carry on with our day to day activities.


Under Human Physiology, one will also learn about the underlying physiological processes in detail. These include respiration, digestion, excretion and so on. 


You will be better able to gain an understanding of this chapter once you start solving the physiology MCQ.  


Objective questions will help you to revise the topics while also strengthening your understanding of essential concepts. Keeping this in mind, the physiology MCQ questions have been selected carefully from all parts of the chapter to help you with your preparation. 


Given below are physiology MCQ from the unit Human Physiology. You can opt to attempt all of the topics or test your understanding of a particular topic by going through the physiology questions from that specific section. 


Considering that this unit is crucial for NEET, you can also access previous year NEET questions on human physiology available at our online platform to enhance your preparation.


As NEET question paper will also contain objective questions such as these, practising these will help to gain an idea regarding exam structure. In addition to that, you can also download more human physiology NEET MCQ from our site.
