What is the name of the protein in the blood that oxygen binds to?
Haemoglobin
500
Which hormone, produced by the pituitary gland, cause the reabsorption of water through the kidneys?

How does the immune system develop an immunity to a particular pathogen?
The body makes specific anti-bodies to target and identify specific pathogens. These anti-bodies help the body identify and respond to the pathogen if it is encountered again.
