Human Physiology – Digestive Processes

Human Physiology – Digestive Processes

>>Dr. Ketchum: So we are now going to be discussing the gastrointestinal system. So there are four basic digestive processes for us to look at. We’ll be discussing secretion, absorption, digestion, and motility. So when we look at this diagram, let’s orient yourself first. And so the mouth—you can see

Human Physiology – Visual Impairments: Corneal Ulcers

>>Dr. Ketchum: Okay, so the next visual impairment are called corneal ulcers. And corneal ulcers are actually an open sore that’s on the cornea. And there’s lots of different causes for these. You could have an injury to the eye. So you’ve poked the eye, for example. You can end

Human Physiology – Functional Anatomy of the Male Reproductive System

>>Dr. Ketchum: In this video we will focus on the functional anatomy of the male reproductive system. Let’s begin by simply identifying structures that are important in the male reproductive system. These include the vas deferens, also called the ductus deferens, the penis, the testes—note that only one testicle is

Urinary System, Part 2: Crash Course A&P #39

It has filled countless diapers, caused discomfort for any number of airline passengers, and it totally ruined the Dude’s rug, which really tied the room together, man. Anatomists call it micturition and I don’t know why because the rest of us know it as urination, which seems like a fine
