Question

Table-3
Structure / Function of blood vessel
Artery
Vein
1. Thickness of walls(thick/thin)
2. Valves (present/absent)
3. Capacity to retain shape when blood is absent
(can retain/can't retain)
4. Direction of blood flow (heart to organs / body
organs to heart)
5. Pressure in the vessel(low /high)
6. Type of blood transported
(oxygenated/de-oxygenated)
Discuss the differences between pulmonary artery and pulmonary
vein.​

Answer 1

Answer:

1.The arteries walls are thick because of the high pressure

2.Veins normally have valves to make the flow of blood in one direction

3.Arteries can't retain while veins retain because of their smooth muscles

4.The direction of blood is heart to organs in arteries while direction of blood is organ to heart in organs

5.Arteries carry blood in high pressure and vein in low pressure

6.arteries is oxygenated blood and veins carry non oxygenated blood

The difference between pulmonary artery and pulmonary vein

The difference between pulmonary artery and pulmonary vein pulmonary artery carries non oxygenated blood while pulmonary vein will carry oxygenated blood
