Veins are thin walled and have valves. Justify |
|
Answer» Veins are thin walledbecause the veins collect blood from different body organs to the heart and they have valves to ensure that blood flows only in one direction Veins collect the blood from different organs and bring it back to the heart. The blood is no longer under pressure so, the walls are thin with valves to ensure that blood flows only in one direction. Veins are thin-walled and have valves that prevent the blood from flowing back in the wrong direction.Veins carry blood heading towards the heart.Blood comming from the tissue has delivered O2 and picked up CO2 from the cell.
