Unit 5 Flashcards
Anatomy and Physiology
heart functions
pumps blood
liver functions
-removes toxins/dead blood cells from blood
-40 major functions
kidney functions
removes access water/dissolved items from the blood
spleen functions
removes dead blood cells from blood (liver=more important)
lungs functions
adds oxygen to blood/removes carbon dioxide, heat, and water from blood
Small intestine function
adds food/water to the blood
red bone marrow function
makes red and white blood cells and platelets
red blood cells functions
transport oxygen
white blood cells functions
attacks germs
platelets
clots blood
properties of water
-polarity
-cohesion
-adhesion
-capillarity
polarity
a property of water in which 1 side of the molecule is slightly positive and 1 side of the molecule is slightly negative by overall, it is neutral
cohesion
a property of water in which 1 water molecule is attracted to other water molecules
adhesion
a property of water in which water molecules stick to molecules other than water (water/sponge)
capillarity
a property of water in which water molecules move upward against gravity through tiny pores or holes (water/sponge)
sugar
-a glucose molecule
-has a backbone of carbon atoms
-has polar side chains with hydrogen/oxygen
lipid
-a fatty acid molecule
-backbone has carbon atoms
-side chains are mostly hydrogen atoms
-there’s a more even sharing between the carbon and hydrogen atoms
what makes sugar dissolve in water?
the water sticks to the polar side chains covering the molecule and hiding it from view
polar
water-soluble~hydrophilic
non-polar
lipid-soluble~hydrophobic
hydrophilic list
sugars, vitamins B,C (water, minerals have a charge)
hydrophobic list
lipids,oxygen molecules, vitamins D,A,K,E
organic compounds
molecules that have carbon atoms and are derived from living organisms
-proteins, lipids, carbohydrates, nucleic acids
surfactant
a lipil protein made by the lungs that reduces cohesion in the air sacs so that they don’t collapse
