Here are some tips for answering Human Physiology NEET questions:

  • Be familiar with the different systems of the body. This includes the digestive system, respiratory system, circulatory system, excretory system, muscular system, skeletal system, nervous system, endocrine system, and reproductive system.
  • Understand the basic functions of each system. For example, the digestive system breaks down food into nutrients that the body can use, the respiratory system exchanges oxygen and carbon dioxide, and the circulatory system transports blood throughout the body.
  • Know the different types of cells, tissues, and organs in the body. Cells are the basic unit of life, tissues are made up of cells that work together, and organs are made up of tissues that work together to perform a specific function.
  • Be familiar with the different types of processes that occur in the body. These include digestion, respiration, circulation, excretion, movement, coordination, and reproduction.
  • Practice answering questions on Human Physiology. There are many resources available online and in libraries that can help you with this.
