Hello. I Am Having Trouble Differentiating Between The Hypothalamus And

Hello. I am having trouble differentiating between the hypothalamus and the pituitary Gland. I searched up the hormones of both and it seems like the hormones they secrete are about the same, which really confuses me. If you could please explain to me the key differences and similarities that would be great. And if you could also explain how they interact. Thank you
