• All tubes are composed of living cells.
• The concentration of substances transported is controlled.

• The rate of flow is moderate and is regulated by vasoconstriction and vasodilation.

• The substancesbbeing transported are: respiratory gases, glucose, amino acids, fatty acids, vitamins, etc.
