-
examples:
- -carbs
- -lipids
- -nucleic acids
-
water is made up of
2/3 of our body weight
-
the dispersed substance
solute
-
medium in which other substances are dispersed
solvent
-
breaking a molecule by water
hydrolysis
-
salt is a
cation n an anion held together by ionic bonds
-
what solutuon will conduct an electrical current
aqueous
-
electrolytes
the molecules that dissociate to form ions that conduct an electrical current in a solution
-
what do electrolytes do
keep us alert and moving
-
main electrolytes;
- -sodium
- -choride
- -magnesium
- -calcium
- -potassium
-
what organ work to keep the electrolyte concentration in your blood constant
kidneys
-
molecule taht dissociates in water and releases H+
acid
-
acids are called
proton donors
-
an increase in H+ ions in body is called
acidosis
-
a molecule that dissociates in water and release OH-
base
-
an increase in OH- ions in body is called
alkalosis
-
alkalosis is
excessive blood an alkalinity caused by an overabundance of bicarbonate in blood or loss of acid from blood
-
normal ph for your body is
7;35-45
-
most important buffer in body
bicarbonate/carbonate acid buffers

-
brown fat -
produce heat and burn energy
-
-
an important source of energy
triglycerides
-
building blocks of proteins
amino acids
-
amino acids are joined together by
peptide bonds
-
3 types of RNA;
- -messenger - carries instructions
- -transfer - brings amino acids

- -marcrophages- immune cells taht can engulf any particles
- -lymphocytes - immune cells
- -mast cells - produce histamine
-
matrix of connective tissue is made of
fibers
-
3 types of fibers are found in;
- -collagen - in tendons n ligaments
- -reticular - helps organs keep shape
- -elastin - skin
-
loose connective cells are -
- - areucular - protective and 3 fibers, gel fluid, support nerves and blood vessels
- - adipose
- -reticular
-
supporting connective tissue includes
bone, cartilage
-
muscular tissues, 3 types;
- -skeletal- voluntary
- -smooth -involuntary
- -cardiac- involuntary (heart)
-
the nervous tissue controls
body n transports messages
-
location of nervous tissue
brain n nerves
-
regeneration is the process of
regrowth of tissues afer damage
-
