, ECPI Anatomy/Physiology 1 + lab Exam
Questions And Answers
Internal environment environment within the body in which the cells live
Cell membrane interior and exterior cell membranes
Interior cell membrane intracellular fluid
exterior cell membrane extracellular fluid
homeostasis the maintenance of a relatively constant internal environment
Interdependency of cells -cells depend on one another
-if some cells arent able to function, other cells and the entire organism may suffer
-structure and function are interrelated
Gradients & Permeability down a gradient (High to Low)
high pressure to low pressure
high concentration to low concentration
, ECPI Anatomy/Physiology 1 + lab Exam
Questions And Answers
Diffusion high concentration to low concentration (concentration gradient)
membrane permeability what is allowed in to the membrane or not
Permeant substance can pass through
Cellular differentiation cells become specialized
-different cell types (muscle/nerve) access information encoded in different genes to make
specific proteins
-proteins that cells make determine the function
Cell membrane mechanisms -determines which substances enter a cell and which cannot
-allow cells to respond to certain signals
