Document Summary
Cells that join together using intercellular substances-tissues. 1,2 or more tissues combined in a particular way to form complex structures called organs. Organ system-collection of organs that work together to perform an overall function. Chemical reactions occur constantly in everyday living (production of new substances is balanced by breakdown of older ones) Cells need a steady supply of oxygen to function properly. Cell is the basic structural and functional component of life. All cells in the human body have certain common features. Cells come from preexisting cells in the body. Organelles-compartments, particles, or filaments that perform specialized functions within a cell. Metabolism-chemical process that takes place in body cells. Cell membrane (plasma)-separates in inside of the cell from the outside. It"s (cid:374)ot a(cid:374) orga(cid:374)elle (cid:271)ut it holds the (cid:272)ellular (cid:272)o(cid:374)te(cid:374)ts together and regulates the flow of substances into and out of the cell. Phospholipid-any of a class of fat-related substances that contain phosphorus, fatty acids and a nitrogen-containing component.
