Nephrone is the most important diagram in this chapter. CBSE also ask either the diagram of nephrone Or neurone. Although it is just an observation of past few years question paper. My honest suggestion is that U should practice the diagram of alimentary canal, villi, and human heart as well because a simple question i.e to explain their structure and function is usually asked
