biology 201 quiz 2

Cards

Metabolism The sum of all chemical processes
Catabolism Breaking down of complex compounds.
Example of Catabolism is Cellular Respiration glucose---> Atp & h20& co2
Anabolism Synthesis of chemical substances.
Example of Anabolism glucose(simple)-->glycoge(complex) (fat) (stored in muscles & liver)
Characteristics of the living human organism Metabolism Catabolism responsiveness movement growth differentiation reproduction
responsiveness responding to potential threats responding to stimuli & fight or flight
movement heart beating walking,talking,writing
growth Have to be able to grow in order to survive
differentiation The process of going from a unspcialized function to a specialized function(EXAPLE Mesocymin stem cell)
What are two different types of reproduction in the human body? mitosis-is asexual reproduction & Sexual-joining of the egg & sperm
Intracellular fluid (ICF) found inside the cell.
extracellular fluid (ECF) Found outside the cell.
Interstitial fluid found in between the cells.
where are some places you would find interstital fluids? Blood plasma lymph cerebrospinal fluid synovial fluid aqueous humor & vitreous body
what is Homeostasis? The condition of equilibrum in the body's internal environiment. humans homeostasis is 98.6 F fluids in the body play an important role in maintaing homeostasis
What are the 3 componets of homeostasis? Receptors-Detect changes in the environment. Control center-Receives that input & decides on oppropriate response. Effectors-Perform the desired action
What are Effectors? they are smooth muscle, skeletal muscle, cardiac muscle, and glands.
Negative feedback When the response generated, reverses the stimulus •Baroreceptors sense blood pressure changes
positive feedback Response inhances the stimulus (EXAPLES sperm production, urination)
Disorder Is an abnormality of structure or function.
Disease is a specific term for an illness characterized by a reconginzable set of signs & symptoms.
local disease Affects one part or limited region of the body.
Systemic disease Affects the entire body or several parts of it.
symptoms Are subjective changes in the body that are not apparent to an abserver.
