Homeostasis Flashcards
(30 cards)
Physiology
the structure function relationship of a healthy animal
Anatomy
structures of an animals body, dictate how the parts will function
intracellular fluid
fluid inside cells
extracellular fluid
blood, plasma, and other fluids outside the cell
cells
obtain nutrients and oxygen, undergo metabolism for energy production. connected by junctions (adhesive, tight, gap) to form tissues
tissues
multiple cells, distinguished by type, cell arrangement and cell junctions
epithelial tissue
skin, lining of digestive tract and glands
connective tissue
tendons and fascia
muscle tissue
skeletal, cardiac, smooth. generate electrical signals and have contractile properties
nervous tissue
neurons. excitable cells, transmit signals
organs
different types of tissues (heart, liver, brain, small intestine, etc)
systems
collection of organs
nervous system
electrical signals
endocrine system
chemical signals (hormones)
muscular/skeletal system
support and movement
cardiovascular system
nutrient/waste transport
renal system
fluid volume, pH, electrolyte balance, waste removal
respiratory system
gets oxygen, removes CO2, pH balance
digestive system
gets nutrients, gets rid of waste
reproductive system
not essential, keeps species alive
integrate
work together
osmolarity
measurement of solute concentration in a solution (bodily fluids). fluids with high concentration solutes relative to solution have high osmolarity
serum osmolarity
isotonic - 300 mmol/L
Hypertonic - > 310-320 mmol/L
Hypotonic - < 280 mmol/L
osmosis
ions in solution
