Levels of Organization

The level of organization on the human includes: Organelles, Cells, Tissues, Organs, Organ Systems and Organisms.

Organelles are subcellular structures, things that are subcellular are Ribosomes, Mitochondria and the Nucleus.

And combined they make cells, which are all different, skin cells, blood cells, brain cells, these are specialised cells, which the scientific names of these cells are, Muscle cells, Glandular cells, and Epithelial cells. 

Next are tissues, these are groups of cells that work together to carry out functions like scar tissue, which is meant to cover up wounds to help them heal by shielding the wound from external sources, the epithelial cells combine together to make human skin along with the inside of our intestines.

The muscle tissue in our ligaments helps our body to move and flex, allowing us to grip things.

It also helps create chemicals and enzymes, like sweat, to cool our bodies and saliva, to help us digest food.

Next are our Organs. Once again, the tissues combine to make a larger structure, for example, the stomach, which breaks down food into proteins. Other things that tissues make are the lungs, teeth, bones, the digestive system and much more.

The organ's job is to 'carry out functions', which is similar to tissues, but can carry out larger processes compared to cells or tissues. These organs make systems like the Respiratory system, the Cardiovascular system, and the Reproductive system.

Then to make the whole organism, as you would need all of the organism's cells, tissues, organelles, organ systems and organs to make a functioning human body.
