For example, as food travels through the digestive system, the organs of the digestive tract break down the food into nutrients the body can use and waste products the body doesn’t need. The pancreas helps us process sugar by producing insulin while the liver processes fats and produces cholesterol, among other substances. TissuesEach organ is made up of tissues that support the organ function. There are four types of organ tissues: epithelium, connective, muscle and nerve tissue.CellsTissues are collections of cells of different types that interact to support the function of the tissues, organs and overall organ system.Levels of Organization – Organ SystemsThe human body is a collection of interacting organ systems. Some of those systems are the cardiovascular system, the digestive system and the nervous system. These organ systems work together to sustain life in the human body.ccccccccccceeeeeeeeeeellllllllllllllllllllllssssssssssssstissuesuesuesorgansepithelialcellstonguegusesophaggmacstommhpa crncc easrge larrgintestineintesintesmall intestinesmall intestmall intestlivvev rconnectivetissue mumusclemunerveCardiovascularRespiratoryDDDDDDDDDDDDDDiiiiiiiiiiiggggggggggggggggeeeeestiveIIIIIIIIIIImmuneReproductive/EndocrineMuscularMMSkeletaaallNervousEEEEEEEEEEEEEEExxxxcreeeeeeeeeeeeeeetttttttttttttttooooooooooooooorrrrrrrrrrrrryWithin organ systems, each orggggggggggaaaaaaaaaannnnnnnnnn hhhhhhhhhhhhaaaaaaaaaaassssssssssss aaaaaaaaaaaaa dddddddddddddiiiiiiiiiiiffffffffffffffffffffffeeeeeerent fffffuuuuuuuuuuuuuunnnnnnnnnnnnnnnnnctiooooooooonnnnnnnnnnnnnnnnnnn oooooooooooooorrrrr sssssssssssseeeeeeeeeeeeett of fffffffffffuuuuuuuuuuuunnnnnnnnctions.
