c) Pulmonary vein. If it is blocked, it will block oxygen from entering the heart muscle cell and cause diseases like Pulmonary Vein Stenosis. This will later cause coughing up blood (hemoptysis) and limit the patient's ability to do daily stuff activities.

X is pulmonary artery and y is pulmonary vein. it is because bloods enter the lung through pulmonary artery and leaves the lung through pulmonary vein

a) ii. The differences between blood vessel X and Y are blood vessel X carry oxygenated blood, however blood vessel Y carry deoxygenated blood. Futhermore, blood vessel X has high pressure due to smaller diameter of cappilary compare to blood vessel Y which has bigger diameter of cappilary at a low pressure.

A i) X is artery because the blood flow is downward and y is vein because the blood flow is upward

ii) characteristic for artery :

- has thick , muscular and elastic wall
- does not have valve except for semilunar valve at the base of aorta and base of pulmonary artery
- high blood pressure

while characteristic for veins :

- has thin , less muscular and less elastic wall
- contain valves to mantain one way flow of blood
- very low blood pressure

b) Thin walls of z that is one-cell thick enables effective gaseous exchange. Secondly it is not muscular because the blood pressure is low]]> 2021-07-07 07:06:54 UTC https://padlet.com/g18140922/wxraxeghlyf8fni/wish/1640012718 Group b https://padlet.com/g18140922/wxraxeghlyf8fni/wish/1640013632 Members
