• Particularly aldosterone---regulate plasma K+ and Na+
• increase aldosterone causes....active reabsorption of Na+ and passive reabsorption of water in the nephron. This increases blood volume and blood pressure
• secreted by adrenal cortex

• decompose dead organic matter
• most bacteria and fungi (ringworm) are saprophytic

Type AB---has neither anti-A nor anti B antibodies

• produce long-term behavioral and physiological alterations in recipient
• Ex. pheromones of male mice affect estrogen cycles of females

• taken back up into the nerve terminal via a protein called an uptake carrier
• degradeded by enzymes in the synpase (acetylcholinesterase...inactivity acetylcholme)
• diffuse out of synapse

region exposed at low tides

• fills area between lens and cornea
• exits through ducts to join veneous blood

increase of pressure in eye due to blockage of aqueous humor outflow

thickwalled, muscular, elastic

thin walled inelastic

• abnormal chromosome #
• can occur by nondisjunction of homologous chromosomes during meiosis, or nondisjunction of sister chromatids during meiosis II

• formed: from stem cells in the bone marrow have lost nuclei, mitoch and membranous organelles
• termination: after 120 are phagocytized by cells in spleen and liver

• type of WBC that has migrated from blood to tissue where mature into stationary cells
• engulf and destroy cells

lines the inside of shell. Moist membrane that permits gas exchange

the pituitary (hypophysis) consists of anterior and posterior lobes

• Involuntary nervous system that regulates body's internal environment
• composed of sympathetic and parasympathetic nervous systems.

Point of attachment of a muscle to a stationary bone (proximal end of limb muscles)

• another antigen on RBC
• Rh+ possesses antigen
• Rh- is lacking

Ex. Rh- woman is sensitized to Rh+ RBC's of fetus. For next Rh+ child will produce antibodies that destroy fetal RBC's resulting in erythroblastosis fetalis (anemia)

• No organized nervous system
• may respond to touch heat, light, chemicals

attach skeletal muscle to bones and bend the skeleton at movable joints

white part of the eye

are in a constant state of transcription (repressor is inactive) unless a corepressor is present to inhibit

• large, multinucleated
• bone resorption
