The steady state within an organism for maintaining health (normal hydration and composition of body fluids, respiratory and heart rate, temperature)

Tissue

Groups of tissues that cooperate to perform a specific systemic function

Ex: Stomach, which consists of epithelia, muscle, nervous and connective tissue

Specialized dyes to recognize various cellular organelles

H&E

hematoxylin and eosin

Cationic, binds to anionic (such as nucleic acids)

Stains blue/purple

Basophilic

Plasma Membrane

Fluid phospholipid bi-layer

Hydrophobic, non-polar directed inward

Suspends intrinsic and peripheral membrane proteins

membrane protein

binds to and moves particles through

the membrane

(transport small substances such as molecules and ions)

Receptor

carbohydrate component

activate or inhibit cell function

Carbohydrate (glyco-)

Identify the cell as "self"

Within

2 methods, each where a vesicle created is then pinched off (a phagosome) within the cell and later fused with a lysosome for intracellular digestion

Method of endocytosis

Cell drinking

Invagination of the cell membrate to entrap extracellular FLUID of anything in solution

Out of cell

2 methods

bulk release of materials

Method of exocytosis

Loss of waste products from the cell

Polysaccharides at the tips of the extrinsic proteins

Protective

Acidophilic
