Define the relationship between anatomy and physiology Anatomy is the study of internal and external body structures and their physical relationships among other body parts. In contrast, physiology, is the study of how living organisms per-form their functions. Discuss form and function All specific functions are performed by specific structures, and the form of a structure relates to its function Cephalic head Frons (frontal) forehead Oculus, Ocular, Orbital eye

____________are substances (solid, liquid, or gas) dissolved by solvents in a solution (lesser amount). solutes ________are the substances that dissolve solutes (greater amount). solvents ___________contain a solvent and the solute. solutions. Example: Salt dissolved in water. Which is the solute and which is the solvent? salt is solute water is solvent Carbon dioxide becomes dissolved by the blood plasma. Which part is the solute? carbon dioxide

Define Homeostasis The existence and maintenance of a relatively constant environment within the body. Lymphatic System Removes foreign substances from the blood and lymph, combats disease, maintains tissue fluid balance, and transports fats from digestive tract. Consist of: lymphatic vessels lymph nodes lymphatic organs Respiratory System Exchanges oxygen and carbon dioxide between the blood and air and regulates blood pH. Consists of: lungs larynx trachea

during the process of tissue repair, which of the following processes produces scar tissue? fibrosis embryonic ectoderm develops in which two major tissue types? epithelial tissue and nervous tissue What type of tissue forms in tendons? dense regular connective tissue the basement membrane is located between which two tissue types? epithelial and connective tissue which of the following types of epithelial tissue lines the interior of blood vessels? simple squamous endothelium which of ...

Gene expression the process by which information encoded in DNA directs the synthesis of proteins or; in some case, RNAs that are not translated into proteins and instead functions as RNAs Ionic bonds Bonds that require donating and accepting electrons Emergent properties Properties of a complex system that are not present within its parts but that emerge only when those parts are combined. Natural selection A process in which individuals that have certain inherited traits tend to survive...

The nervous system is? The master controlling and communicating system of the body The three functions of the nervous system are? 1. Sensory input 2. Integration 3. Motor output The sensory input gathers information by the internal and external sensory receptors The integration function processes and interprets the sensory input The motor output function activates the effector organs (muscles and glads) and produces the appropriate response

epidermis superficial region of skin composed of epithelial cells dermis middle region of skin composed mainly of fibrous connective tissue (fibroblasts) and occasionally mast cells as well as white blood cells hypodermis subcutaneous layer deep to skin composed mainly of adipose tissue, not technically part of the skin keratinocytes cells in epidermis that produce fibrous protein keratin; dead at the surface and held together by desmosomes when alive

Proton Positive Charge Heavy Mass Election Negative Charge Light Mass Neutron No charge Heavy Mass Atomic Structure Proton, Neutron, and Election

What term refers to the type of control, in which the response opposes the stimulus? Negative Feedback Define homeostasis Regulating conditions to maintain optimum functions for life What is the fundamental difference between gross structures and microscopic structures? Gross- large enough to see w/ the naked eye Microscopic- require a microscope to see

What is anatomy? study of structure What are the 3 divisions of anatomy? microscopic, gross and developmental What is physiology? study of function What are the 6 structural levels studied in physiology? molecular, cellular, tissue, organ, organ system, organismal What is the relationship between anatomy and physiology? principle of complementarity
