What's a better major Health Science or Biology?

I am a high school senior who is considering becoming a Pharmacist or taking the MCAT and trying to get into medical school and i was wondering which if these two majors would best assist me in terms of GPA and personal interests. I am most interested in learning the works of the human body and the different factors that can change it?

My mistake ignore the Northeaster University part, I was looking at a thread about it
