Neurons The neuron is specialized to send messages very quickly Different structures and functions The same DNA can have a different structure and function because DNA codes for specific proteins which determine these factors Cell structure Cell function will dictate cell structure including organelle types, numbers, and cell shape Cell Specialization Levels of Organization in Cells Example organism Organ Systems A complex structure of interdependent and subordinate elements that create a life form. A bird, sea sponge, and human are all examples of organisms Organs working together to perform certain functions form organ systems. Organisms Formation of Tissue Different types of cells performing specialized functions form a tissue List tissues and function Tissues Nervous: sensory input, integration, and motor response Muscle: the fibers contract and relax to provide movement Connective: bind other organs together, hold organs in place, cushion them, and fill space. Epithelial: secretion, selective absorption, protection, transcellular transport, and sensing Organs Formation of organs Two or more different types of tissue working together to perform a specific function Example of an organ and its function Lungs perform the process of gas exchange. Oxygen comes in and enters the blood stream and carbon dioxide exits as a waste product of metabolism Organ Systems Define organism Organ systems working together to form a fully functional living being that can thrive in a particular environment Formation of organ systems Organs working together to perform certain functions form organ systems. List 6 organ systems and function Skeletal: support, movement, protection, blood cell production Muscular: movement, stabilization of joints, and generate heat Digestive: digestion and absorption of nutrients Respiratory: process of gas exchange Nervous: sensory input, integration, and motor response Circulatory: transport blood and oxygen
