A union of two sets is a set that contains all the elements of the two sets.

$A=\{ \mbox{ all men } \}$
$B=\{ \mbox{ all women} \}$
Then,
$A\cup B=\{ \mbox{ all people (except TPH for he is not human) } \}$

The intersection of two sets is a set that contains all elements that are in both sets.

$A=\{ \mbox{ all people with hair } \}$
$B= \{ \mbox{ all people with eyes} \}$
Then,
$A\cap B=\{ \mbox{all people that have hair and eyes} \}$
