Question

short note of lungs and microscope

Answer 1

Answer:

Lungs-The lungs are the primary organs of the respiratory system in humans and many other animals including a few fish and some snails. Their function in the respiratory system is to extract oxygen from the atmosphere and transfer it into the bloodstream, and to release carbon dioxide from the bloodstream into the atmosphere, in a process of gas exchange.

Microscope-A microscope is an instrument used to see objects that are too small to be seen by the naked eye. Microscopy is the science of investigating small objects and structures using such an instrument. Microscopic means invisible to the eye unless aided by a microscope.
