Document Summary
The study of all normal functioning of living organisms: chemical and physical. Genome: all genetic info in dna of species. Emergent properties: properties arise from collaboration and functioning of systems; do not belong to any one system. Cell cell membrane tissues organs organ system. Digestive system: takes in nutrients, expels wastes. Reproductive system: production of eggs and sperm. Nervous and endocrine systems: coordinate body functions. Circulatory system: pump blood, distribute materials. Immune system: protect internal from foreign material. Theme 1: structure and function are closely related: molecular interactions. Function depends on size, shape: proteins. Theme 2: living things need energy: building and breaking down molecules, transport molecules, create movement. Theme 3: information flow coordinates with body functions: chemical, electrical signals. Theme 4: homeostasis maintains internal stability: internal environment is a condition . Constantly changing, readjusting: failure to meet homeostasis diseased state. Failure can be internal or caused by external source. Extracellular fluid: internal environment surrounding cells.
