Critical Physiology
Anatomy, Physiology, Health, and Fitness
Getting Started
So, you’ve decided to study Anatomy & Physiology! Are you preparing for a career in medicine? Are you interested in understanding the processes that underly health and fitness? Do you want to know how your body works? Or are you a masochist?
A Brief Intro to Chemistry for A&P Students
A brief introduction to chemistry for Anatomy & Physiology students. This section won’t make you an expert chemist, but it will provide all the information you need to get started with A&P.
Intro to The Cell
In this section, you will learn about the cell and how it functions.
A Brief Rant About Science Education
I was recently notified that one of my YouTube videos had been “age restricted.” In the video, I dissect a sheep’s brain and describe all of the relevant structures of the brain. I posted the video years ago for my online students to watch….
Membrane Transport: Passive Transport
We’ve just described the cell’s Plasma Membrane (PM) and how it separates the water inside a cell from the water outside a cell. But no man cell is an island. Except pancreatic islet cells, which is a joke we won’t cover until A&P 2.
Intro to the Cell: The Plasma Membrane
We all know that the body is filled with water. And that cells are filled with water. So, how do you separate the water inside a cell from the water outside of a cell? It all starts with the Plasma Membrane or PM.
