Will give 5 stars and brainliest for correct answer i need on a question which is 1. for your organ system, describe how the system works at the tissue level. let me explain. i choose the respiratory system and i have to, as the question says, describe how the system works at tissue level. the 3 levels are organ system (i choose respiratory) organs (lungs, nose and trachea) tissue so basically the question is 'describe how the respiratory system works at the tissue level (what happens after you do the oxygen process, i guess just explain where the oxygen used goes? )

The body has levels of organization that build on each other. Cells make up tissues, tissues make up organs, and organs make up organ systems. The function of an organ system depends on the integrated activity of its organs. For instance, digestive system organs cooperate to process food.

The heart pumps blood through the lungs. In the lungs the blood receives oxygen and releases carbon dioxide. ... When the oxygen-rich blood gets to the cells, the cells receive the oxygen and release the carbon dioxide.

They deliver oxygen to the brain :)
