Though the size of the organ is greater than the tissue and requires more energy to perform any function. When we have a group of similar cells working together this is called a tissue, for example muscle tissue is made up of lots of muscle cells.All the cells in a tissue look the same and perform the same job. Organs. • The body has levels of organization that build on each other. Level 2 - Tissues It is created by joining cells that have similar function or structure. Examples Stomach-muscle tissue, nerve tissue, blood tissue. As such, it is a key example of a system: a collection of items or organisms that are linked and related, functioning as a whole. Root. Examples of human organs include the brain, heart, lungs, skin, and kidneys. 0. Cells are the smallest unit of living matter.
