I took Anatomy and Physiology freshman year with seniors. Is that considered a honors class ? I took Anatomy and Physiology, Earth Science and taking Chemistry now. What classes are considered Honors ?

I would imagine that it is an honors class if your school calls it an honors class and if there is an H on your transcript next to the class/subject. Chemistry (for example) could be regular, honors, or AP.

Your HS determines which classes are Honors. Ask your GC if it is not readily apparent.
