Why is homeostasis important? - (ANSWER)to maintain a relatively stable
environment, within limits.
How does the body maintain homeostasis? - (ANSWER)through cooperation of
multiple organ systems, including the endocrine and nervous system
What is a homeostatic set point? - (ANSWER)The level in where the temperature
of the body is maintained.
Which organs are involved in water, and glucose balance? - (ANSWER)The small
intestine is involved with balancing water. The pancreas is involved in balancing
glucose.
Where do different molecules enter your body? - (ANSWER)The Blood Stream.
How are they absorbed? - (ANSWER)osmosis
How do they get to other regions of the body? - (ANSWER)Through the blood
stream
What are capillaries? - (ANSWER)any of the fine branching blood vessels that
form a network between the arterioles and venules.
, What is interstitial space? - (ANSWER)space/fluid in BETWEEN cells
How do different types of molecules (water, glucose, oxygen, sodium, chloride)
cross cell membranes and travel between different organs? - (ANSWER)Cell
membrane is semipermeable to water. Oxygen move across cell membranes
simple diffusion, a process that requires no energy input and is driven by
differences in concentration on either side of the cell membrane. Food is broken
up through digestion and diffuse into the blood through microvilli in the intestinal
wall.
How is water regulated in your body? - (ANSWER)Homeostasis
What is osmosis and what does it have to do with water balance? - (ANSWER)The
diffusion of water to create an equilibrium with salt.
Where does the water in your body come from? - (ANSWER)Liquids, foods and
cellular respiration.
How does your body eliminate water? - (ANSWER)Through urinating, sweating,
and feces.
Which organ systems are involved in water balance and what is their role? -
(ANSWER)kidney regulates by controlling water concentration in blood plasma
