The ​ (a)   are connected to every cell in our body and gives each cell ​ (b)   , while taking away ​ (c)   .

This deoxygenated blood then travels back to the ​ (a)   side of the heart through the ​ (b)

The blood enters the ​ (a)     ​ (b)   first. Then the heart beats, sending the blood into the ​ (c)    ​ (d)   .
