Document Summary
Study guide: multicellular life, animal organization, definitions, tissue: cells of same type, neurons (nerve tissue), epithelial cells (skin tissue, organs: tissues producing a joint function, heart - pumps blood. Immune system: entire body network to fight off diseases: advantages of multicellular life. Increased efficiency by specialized function of cells and organs; fine-tuned function: controlled shape: shape adapts to environmental needs, e. g. birds and fish streamlined, humans walk on 2 feet. Large size: good defense: controlled internal environment: temp, oxygen in blood. Can live on land - can take in water without living in water: disadvantages of multiceullar life. S/v ~ r2/r3: as size (r) goes up, s/v goes down, as dimensions increase, volume increases drastically compared to the surface area increase. Transport: access to nutrients at surface is low. So specialized organs develop: removal of wastes >> specialized organs. Support: carry large weight, animal tissues, four main categories, epithelial tissue.
