Human physiology chapter 1-4 questions and answers latest top score. the study of how living organisms function -very broad range of application: from molecular to microscopic to whole body function - correct ology what are the major themes of physiology - correct answers.1. structure and function closely related 2. living organisms need energy -energy source, transfer, storage, and use 3. information flow coordinated body function 4. homeostasis maintains internal stability despite external variables physiologists ask why the individual parts of the body work together, also known as - correct rated function physiologists ask how various levels of organization are integrated, also known as - correct nistic approach physiologists apply understanding to the ______ of the human body - correct ll function What is the difference between anatomy and physiology - correct my: -organizational levels, individual parts, deconstruct human body physiology: -function of organizational levels, individual parts working a cohesive organism, reconstruct the human body GO TO - correct answers.SLIDE 5 During early development all cells are ______ - correct same with time each cell becomes _____ - correct alized the process by which a cell becomes specialized for a specific structure or function - correct differentiation cells become specialized based on - correct ion explain how the body is organized on a chemical level - correct answers.(molecular level) -small molecules: carbon dioxide and water -macromolecules: carbs lipids proteins and nucleic acids how is the body organized in a cellular level - correct and their functional subunits (organelles) how is the body organized on a tissue level - correct of cells working together to perform common function; 4 types of tissue: -epithelium: covers body's surface -connective: provides support -muscle: movement -nervous: communication in the chemical level of body, what are the small molecules? - correct n dioxide and water in the chemical level of the body, what are the macromolecules? - correct answers.4 classes carbs, lipids, proteins, and nucleic acids what are the four types of tissue - correct elium connective tissue muscle nervous what is epithelium - correct e that covers body surface what is connective tissue - correct des support what is muscle tissue - correct ent nervous tissue - correct nication a discrete structure made up of more than one tissue; functional center - correct level organs working closely together for common purpose - correct system highest level of organization. result of all simpler levels working together - correct ism level cellular level: cells are made up of ___ - correct ules tissue level: tissues consists of ___ - correct ar types of cells chemical level: atoms combine to form _ - correct ules watery solution of dissolved substances (oxygen, nutrients, etc.) present in the body - correct fluids fluid in the blood and surrounding cells (outside cell) - correct cellular fluid 20-25% of extracellular fluid is ____ 75-80% is ____ - correct answers.20-25: blood (plasma) 75-80: interstitial fluid extracellular fluid that lies around and between cells in space called - correct stitial total volume of extracellular fluid is the sum of the _________ - correct a and interstitial volumes extracellular fluid is considered as ___ - correct eneous fluid located inside the cells - correct cellular fluid composition of extracellular fluid is _____ from that of intracellular - correct different intracellular fluid may contain ____ and other factors for cellular growth and development - correct ins what is an important way cells regulate their own activity - correct aining differences in fluid composition across cell membrane body fluids and compartments (should or should not) be considered homogeneous - correct d not do differences exist within organelle fluid in same cell? - correct more fluid _____ cells than _____ - correct e than out ______ is necessary for cellular information exchange and communication - correct compartmentalization what is the defining principle for understanding physiological homeostasis - correct fluids and compartments can cells work independently? - correct work together in functionally related communities - correct mal def of tissues a group of closely associated cells that perform related functions and are similar in structure - correct l def of tissue are tissues just living cells? - correct non-living extracellular component (extracellular matrix) what is the basic function of connective tissue - correct rt what is the basic function of epithelial tissue - correct ing what is the basic function of muscle tissue - correct g what is the basic function of nervous tissue - correct ol -sheet of cells covering a body surface or lining a body cavity - correct elial tissue tissue that forms most of body's glands. occurs at interfaces between differing environments -inside vs outside of body (epidermis) - correct elial tissue what are the functions of epithelial tissue - correct ct role as interface tissues -protection -secretion -absorption -ion transport -filtration -forms slippery surfaces tissue that connects and bind organs together, holds in body fluids, form basis or skeleton, store and carry nutrients, surround all blood vessels and nerves, protect against infection - correct ctive tissues -composed of muscle cells/muscle fibers -elongated shape able to contract (shorten) -arranged in myofilaments that contain actin and myosin - correct e tissue what are some functions of muscle tissue - correct ent maintenance of posture joint stabilization heat generation what are the 3 types of muscle tissue - correct tal cardiac and smooth what are the 2 types of cells in nervous tissue - correct ns and supporting cells (glial cells) specialized nerve cells conduct impulses composed of cell body, dendrite, axon - correct ns nonconducting that nourish, insulate and protect neurons - correct rting cells (glial cells) cell characteristics of nervous tissue - correct mitosis (cell replication) longevity high metabolic rate -defining principle underlying physiology -defines as a state of reasonably stable balance of physiological variables -"normal" - correct stasis most of the common physiological variables of the body are maintained within a predictable range thanks to - correct stasis examples of the physiological variables of homeostasis - correct pressure body temperature blood glucose levels is homeostasis a dynamic or static process? - correct ic if the amount of substance in the body is to remain constant, any gain must be offset by an equal loss (drink, pee, repeat) - correct of mass balance physiological variables can change dramatically over a 24 hour period, but the system remains in overall balance - correct ic constancy when homeostasis is maintained - physiology when it is not, ______ - correct physiology
