What does the Kidney do? - Produces Urine Functions of Kidney - 1. Excretion -removal of wastes from body fluids into urine 2. Regulation of Blood -Ions a. control blood Na+ (sodium), K+ (potassium), and Cl- (chloride) levels -ph a. control blood H+ (hydrogen) and HCO3- (bicarbonate) levels -Pressure and Volume a. control blood fluid volume and therefore blood pressure What three processes do the Kidneys use to perform their functions? - -Filtration of water, ions, ...

5 cranial senses - olfaction, taste, vision, hearing and equilibrium Olfactory pathway - odor-olfactory receptors-olfactory nerves-olfactory bulbs-olfactory tracts-olfactory cortex Gustatory Pathway - Taste buds are on the dorsal surface of the tongue taste-receptors- cranial nerves-medulla-gustatory cortex 6 primary taste sensations - sweet salty bitter sour umami water Cranial Nerves - Facial nerve(CN VII)- anterior 2/3s on tongue Glossopharyngeal (CN IX)- posterior 1/3 on ...

5 special senses - olfaction, taste, vision, hearing, equilibrium and balance where is the olfactory pathway located? - on the temporal lobe of the cerebral cortex what is the pathway of odor the olfactory cortex? - odor goes to the olfactory receptors, pass through cribriform plate of ethmoid bone, CN I synapses on neurons in olfactory bulbs, whose axons form olfactory tract, and then goes to the olfactory cortex gustatory (definition) - taste Where are taste receptors located? - de...
