Water

HideShow resource information
Transport medium; blood
Plasma; mainly water, proteins, amino acids, salts, enzymes, hormones, antibodies, urea, red and white blood cells, platelets. Regulates blood temp, transfers energy.
1 of 5
Solvent properties of water
Chemicals dissolve easily in water, free to move so can react. Dissolved substances transported around organism. Ionic molecules dissolve easily. Neg ions attracted to pos end of water, pos ions to neg end of water. Ions become hydrated in solution.
2 of 5
Continued
Polar molecules dissolve easily; hydrophilic. Substances go into solutions. Non-polar molecules do not dissolve; hydrophobic. Enable transport in blood.
3 of 5
Thermal Properties
Heat capacity of water is very high. Large amount of energy required to break hydrogen bonds. Large input energy> small increase in temp. Avoid rapid changes in temp, maintain steady temp even when external temp varies considerably
