A sequence of videos designed to create a foundation of understanding of the 12-lead ECG in pre-health profession freshman and sophomore students. This video should not be considered clinically relevant, rather I hope it serves as a basis for understanding the biophysics of ECG recordings so that the interested student can use it to further develop their understanding of ECGs. Relevant topics covered will be an introduction (Part 1), diagnoses possible (Part 1), cardiac conduction cycle (Part 2), Einthoven's triangle(Part 2), how ECG leads detect the voltage changes in the conduction cycle (Part 3), a basic understanding of leads I, II, and III, augmented leads (Part 4), QRS axis (Part 5), Precordial leads (Part 6), and a return to diagnoses using http://www.ecglibrary.com (Part 7).

Part 2 of three videos discussing the sodium-dependent reabsorption of filtrate at the proximal convoluted tubule in the kidney. Glomerular filtration rate, as well as the effects of too high a GFR and too low of a GFR, are briefly discussed. Compensatory mechanisms to regulate GFR are briefly reviewed though it would be beneficial to watch the video titled glomerular filtration rate prior to this video. This video then discusses the affect of hypernatremia and hyponatremia on the ability of the PCT to reabsorb nutrients as well as wastes like urea from the filtrate and back into the blood; hypernatremia will decrease reabsorption while hyponatremia increases reabsorption. Lastly, the consequence of too high of protein or glucose in ones diet, and how it causes hyponatremia (and increased reabsorption), is described. This video is intended for freshman/sophomore pre-nursing students.

Part 2b of a multipart set of movies designed to explain the cells and strategies of the human immune system to freshman/sophomore pre-nursing students. This movie follows after Immune System in Class: Part 2a First Line of Defense.mp4 and completes the discussion of the second line of defense or non-specific Defense.

Part 3b of a multipart set of movies designed to explain the cells and strategies of the human immune system to freshman/sophomore pre-nursing students. In this movie, we speak more specifically about the anatomy and physiology of the third line of defense, the specific or adaptive immune system. For a complete description, please follow this movie with Immune System in Class: Part 3c and Part 3d.

Part 2 of a short two part video outlining the homeostatic methods the body uses to maintain balance of hydrogen ion, hydroxyl ion, and pH. Causes, effects and the body's method to remedy alkalosis and acidosis are discussed.
