Here Paul Andersen gives you a brief introduction to The Cell Membrane.
In Crash Course Biology #5 – In Da Club – Membranes & Transport, Hank describes how cells regulate their contents and communicate with one another via mechanisms within the cell membrane.
In Crash Course Biology #27 – Circulatory & Respiratory Systems, Hank takes us on a trip around the body – we follow the circulatory and respiratory systems.
