CHAPTER 31: Respiratory and Circulatory Systems

31.1 RESPIRATORY SYSTEMS


Avian Respiratory Dynamics
How do birds breathe more efficiently than mammals? This Shockwave animation shows how birds keep a constant stream of air flowing through their "lungs."

31.2 EVERY BREATH YOU TAKE


How the Body Works: The Respiratory System
This is a Shockwave animation of respiratory anatomy and how it looks when you cough, sneeze, and hiccup.

Respiratory System
To get to this part of the BodyQuest human anatomy site, click on Respiratory System under Find. Here you can learn about gas exchange and view graphics of the lungs.

31.3 HEALTH OF THE RESPIRATORY SYSTEM


Asthma
Resources and information about asthma can be found at The Rural Health Village.

Breathing Trouble
Asthma made the headlines in 1997 after it was found that a large percentage of asthmatic children in inner-city neighborhoods were allergic to cockroach allergens. Here, The Why Files explore this troubling respiratory disorder, reporting on statistics, triggers, and treatments.

The Air That We Breathe
Science magazine The Why Files takes a look at air pollution, its effects on respiratory health, and where it comes from.

31.4 CIRCULATORY SYSTEMS


Cut to the Heart
Learn about the history of heart surgery, take a look at diseased hearts, and see an animation of how blood flows through a beating heart at this excellent NOVA website.

The Heart and the Circulatory System
While the function of the heart may seem obvious today, it wasn't 500 years ago. Read this Access Excellence article to learn about the notions that preceded William Harvey's 1628 book On the Movement of the Heart and Blood in Animals. This article also discusses the circulatory systems of invertebrates and non-human vertebrates.

The Circulatory System
This chapter from Maricopa Community College instructor Michael Farabee describes the types and components of circulatory systems, as well as the lymphatic system.

31.5 BLOOD


All About Blood
What's the most common blood type in America? When was the first blood transfusion attempted? This fact sheet from the American Association of Blood Banks describes blood donation and the uses of donated blood.

Artificial Blood
What if you worked in an emergency room and ran out of a rare blood type? U.S. companies are working to get artificial blood substitutes to the market, products that could change emergency medicine dramatically.

31.6 HEALTH OF THE CIRCULATORY SYSTEM


The American Heart Association
What's your risk for heart disease? What does the latest research tell us about our cardiovascular health? Learn about heart diseases and strokes from the organization committed to public awareness and research of these two health problems.

Cardiovascular Information
This page from the National Heart, Lung, and Blood Institute discusses high blood pressure, cholesterol, obesity, heart attacks, and other circulatory system facts. The NHLBI also has a page full of Blood Information.

Bypass Ahead
Explore bypass surgery with science magazine The Why Files, as they follow surgeons through this grueling procedure.
