Q
Functional differences
A
Artery Transport of blood:from heart to tissue Type of blood: Oxygenated except pulmonary artery Rate of blood flow:Fast Blood pressure: High
Vein Transport of blood:from tissue to heart Type of blood:deoxygenated blood except pulmonary vein Rate of blood:slow Blood pressure:low
Capillaries
Transport of blood:links atrioles and venules
Type of blood transported: gaseous exchange
Rate if blood: slow
Blood pressure:low
