Arrange the sentences in order to describe how oxygen from air is transported to the cells in the kidneys.

A-The air diffuses into the capillaries surrounding alveoli’s

B-Air enters the bronchioles in the lunges and reaches the alveoli’s

C-The pulmonary veins carry oxygenated blood to the heart

D-The left atrium fills with oxygen rich blood and contracts to fill the left ventricle

E-The capillaries join together to reach the arteries transferring the oxygen

F-The oxygen rich blood moves from the aorta and reaches the kidneys through a series of blood vessels

When a person breathes the oxygen enters the bronchioles in the lungs. From there, the oxygen enters the alveloi. The gas exchange occurs in the capillaries surrounding the alveloi. The oxygen enters the blood in these capillaries. These capillaries then join together to form arteries, which transport the oxygen. The pulmonary veins then transport this oxygen rich blood to the heart. The left atrium pumps this blood to the left ventricle, from where it enters the aorta, which transfers the blood to the kidneys through a network of blood vessels.

Hence, the correct sequence of the events will be : B A E C D F
