Organs and tissues work together to keep cells, tissues, and other system parts alive. Tissues and organelles are found in all multicellular organisms.
What is Organs?
An organ is a collection of organs that perform different functions. This organ is large and forms part of the body. The group of parts together form the structures of the organs.
Organs are a large part of an organism. In general, there are about 78 organs in the human body and these include the brain, heart, liver, lungs, kidneys, the five most important organs for the existence of life.
