Intro to Chemistry: Reactions & Interactions

In this post, I’m only going to cover information that is relevant to people studying Anatomy & Physiology or Biology. Personally, I’m in a long-term love-hate relationship with Chemistry. So, last time we discussed the atom. Why? Because atoms make up molecules and molecules… Continue Reading “Intro to Chemistry: Reactions & Interactions”

Intro to Anatomy & Physiology

First, what are Anatomy & Physiology? “Anatomy” comes from Greek, meaning “to cut up”. Anatomy is the study of the structures in the Body. Physiology is the study of how those structures function. They’re technically two different, distinct fields of study but we always… Continue Reading “Intro to Anatomy & Physiology”
