Restrictive diseases on the other hand cause problems with lung expansion. The second supply comes from the pulmonary arteries which bring deoxygenated blood from the right ventricle of the heart to the alveoli of the lungs for gas exchange.

In asthma, there's a reversible antibody-mediated hypersensitivity reaction in the airways in response to a trigger, for example, cold air or pollen.

From YouTube , produced by mrfordsclass. This video continues our look at the Respiratory System, with the trachea and the bronchi. This is Lesson 4 in our Respiratory System series. This is part of our Anatomy and Physiology lecture series.
We breathe constantly, but have you ever thought about how breathing works? Discover the ins and outs of one of our most basic living functions-- from the science of respiration to how to control your breaths. Found by Rockefellerteacher in Respiratory System. The previous video we looked at the upper respiratory tract.
This starts to look at the lower respiratory tract, specifically the larynx. Our second video in our Respiratory System series for Anatomy and Physiology covers the following: A good overview or preview.
A handout with terms would be of benefit as the video moves rapidly. Found by freealan in Respiratory System. Welcome to the first video in our Respiratory System series for Anatomy and Physiology. This video covers the following: Your lungs pull in oxygen through your nose, mouth, and throat.
Then, in the lungs, the oxygen is transfered to the blood vessels and the lungs draw waste, carbon dioxide, out of the veins. You can then exhale all of the waste!

Have you ever really thought about how they work? Do you know they are just one portion of the body's entire respiratory system? The lungs may be what you immediately think about when you hear the term 'respiratory system,' but the truth is that this system is made up of more than just the lungs.
The lungs need assistance from other parts, like airways and blood vessels, in order to properly do their job. In this chapter, you will learn about the respiratory system, including an in-depth look at the lungs and all the other associated parts of this system. Lessons will touch on the process of gas exchange and transport. You'll take a look at how breathing is regulated, too. Some of the things you'll have learned by the end of this chapter include:. External and Internal Respiration in the Lungs: Oxygen and Hemoglobin Analyze how gas is transported in the body.
Cooperative Binding of Oxygen with Hemoglobin Explore what happens between oxygen and hemoglobin. Carbon Dioxide Transport in the Blood Examine how carbon dioxide is transported in the blood. How Ventilation is Regulated Discover how our bodies know how to breath in and out. What are Pulmonary Function Tests? Take a look at the different pulmonary tests and what they are used for.
The respiratory system includes the lungs as well as other organs that help to get oxygen into the blood and carbon dioxide out of the blood. The conducting zone of the respiratory system carries oxygen into the lungs and carbon dioxide out of the lungs. The respiratory zone is where oxygen and carbon dioxide move into and out of the blood. Each lung is contained within a pleural cavity, the space between the outside of the lung and inside of the chest wall.
Pleural membranes cover the outside of the lungs and line the inside of the chest wall. The lungs remain expanded when we breathe due to a vacuum effect within the pleural cavity. It includes both inspiration and expiration, the movement of air into and out of our lungs.
In this lesson, learn about how the diaphragm contracts and relaxes and its impact on lung volume. The respiratory membrane includes millions of alveoli with a surface area as large as a tennis court. This large respiratory surface area, combined with other factors, makes for efficient gas exchange to meet our metabolic needs.
Our lungs are lined with a thin layer of water. The water creates surface tension, which makes it difficult for the lungs to expand and allow for gas exchange. Pulmonary surfactant is made by our lungs and decreases the surface tension so we can breathe. If you've ever experienced shortness of breath on top of a mountain, this lesson is for you. Oxygen and carbon dioxide move into and out of our blood by diffusion. The rate of diffusion is determined by partial pressure gradients across the respiratory membrane in our lungs.
Partial pressure is a function of both concentration and atmospheric pressure. This lesson explores the process by which oxygen and carbon dioxide get into and out of the blood located in the lungs and in our metabolizing tissues. The partial pressure gradient for each gas determines both the direction and rate of diffusion across the respiratory membrane. Did you know that almost all of the oxygen transported in our blood is bound to hemoglobin? Hemoglobin is loaded with oxygen in the lungs and unloaded of oxygen in the metabolizing tissues.
This lesson will describe how oxygen is transported in our blood. Our cells need oxygen. Most of the oxygen is delivered to our cells bound to hemoglobin. This lesson describes how cooperative binding of hemoglobin maximizes oxygen delivery to our metabolizing tissues.
Hemoglobin carries almost all the oxygen to our metabolizing tissues. This lesson discusses physiological factors that stimulate hemoglobin to unload oxygen in our tissues. For example, temperature, carbon dioxide, pH and metabolism all influence the affinity of hemoglobin for oxygen. While carbon dioxide is a metabolic waste product, it plays some important physiological roles as well. This lesson describes how carbon dioxide is transported in our blood, how carbon dioxide is converted into a pH buffer, and how carbon dioxide helps with oxygen transport.
Did you know that our nervous system controls our breathing? This lesson describes the basic elements of the homeostatic system responsible for balancing oxygen supply with metabolic demand.
Pulmonary function tests are used to measure air movement into and out of the lungs. Spirometry is the most common way to measure airflow. This lesson will describe the use of spirometry to measure lung volumes and flow rates as well as how breathing disorders are diagnosed.
