Structure ( anatomy ) and function ( physiology ) are studied together because function is determined by structure. Natural selection has "fitted" structure to function by selecting, over many generations, what works best within a particular population The long bill of the sword-billed in it's environment. hummingbird makes it particularly suited to extracting nectar from flowers with deep hypanthium (nectar What elephant adaptations make it suited for its environment? chamber).

Slide 16 / 116 Slide 17 / 116 Epithelial Tissue Tissues Epithelial Tissue consists of many cells tightly packed together with very little extracellular matrix. It covers body surfaces and lines internal organs and body cavities. One side of the tissue is anchored to the underlying tissues by a basement membrane (a dense layer of extracellular matrix consisting of fibrous proteins and polysaccharides.) The other side is the free surface and it faces the outside of an organ or the inside of a tube or passageway.
