- Osmotic Balance
- water balance
- illness
- cause fever, vomiting or diarrhoea
- result in dehydration
- blood water concentration is too low
- sweating
- water, ions and urea are all lost in sweat
- exhalation
- water in the lungs leaves through the persons breath
- eating too much salt
- can make blood ion concentration too high
- illness
- hypertonic
- lower water concentration
- higher ion concentration
- blood becomes hypertonic
- cells lose water by osmosis and shrink
- hypotonic
- higher water concentration
- lower ion concentration
- blood becomes hypotonic
- cells gain water by osmosis and burst
- isotonic
- same water and ion concentration
- homeostasis works to regulate bloods water and ion concentration so it remains isotonic
- kidneys
- ion levels
- must be kept relatively constant to control osmosis and diffusion between cells in the body
- excess water
- volume of water in the blood is monitored by hypothalamus
- ion levels
- water balance
