a type of protein that attachs cell membranes to one another or to internal or external structures
endocrine system
structures of this system include the pineal gland, pitutitary gland, thyroid gland, parathyroid gland, thymus, adrenal glands, kidneys, pancreas, and gonads; functions include directing long-term changes
osmosis
the movement of water across a semipermeable membrane from one solution toward another solution that contains a higher solute concentration
muscular system
functions of this system include locomotion and heat production; structures of this system include skeletal muscles, tendons, and aponeuroses
peripheral proteins
attach to the inner or outer surfaces of the membrane and are easily removed
respiratory system
structures of this system include nasal cavities, paranasal sinuses, pharynx, larynx, trachea, bronchi, lungs, and alveoli;functions include delivery for air and gas exchange
exocytosis
the ejection of cytoplasmic materials by the fusion of membraneous vesicle with the cell membrane
channels
transport proteins that forms a passageway that permits the movement of water and small solutes across the cell membrane; have two major types: leak(permit continuous passive movement) and gated(close or open to regulate ion movement)
hydrophobic
incapable of freely associating with water molecules; insoluble (TAILS)
integumentary system
functions of this system include protection from environment; structures of this body system include cutaneous membrane (skin), hair, nails, and exocrine glands
