2. The Human Respiratory System Let's review the structure and function of the different parts of the human respiratory system. The nasal cavity is where incoming air is filtered, warmed, and humidified. The pharynx is the place where the paths of food and air cross. The larynx produces voice sounds.
3D model. The respiratory system includes organs and structures responsible for gas exchange, supplying oxygen to the body, and removing carbon dioxide. Major components are the nasal cavity, pharynx, larynx, trachea, bronchi, and lungs.
Introduction to Anatomy & Physiology: Crash Course Anatomy & Physiology #1. In 47 episodes, Hank Green will teach you anatomy and physiology! This course is based on an introductory college-level curriculum.
Today we’re going to talk about how it works, starting with the nameless evolutionary ancestor that we inherited this from, and continuing to the mechanics of both simple diffusion and bulk flow, as well as the physiology of breathing, and finishing with the anatomy of both the conducting zone and the respiratory zone of your respiratory system.
So a lot improvements have been made to it over the eons, but the respiratory system that you are using right now is your inheritance from that ancient ambitious fish, leader of one of the most anatomical revolutions in the past half million years. *Crash Course Intro Music*.
Anatomy The respiratory system consists of structures involved in moving air into and out of the lungs (bulk flow) and in gas exchange (diffusion). LUNGS AND CHEST WALL act as a unit. Each lung is surrounded by a membranous sac (pleura) filled with a thin film of fluid (Fig. 1). This intrapleural fluid serves as a lubricant so the
So we all know that breathing is pretty important, right? Today we're going to talk about how it works, starting with the nameless evolutionary ancestor that...
