Additional Resources:

 

Fact Sheet from the American Association of Blood Banks.

Details of the ABO Blood Groups.

Both of the above resources are helpful in "predicting the success of Blood Transfusions," an Analyzing Data feature on page 954 of the Dragonfly Book.

Teaching Resource:

A Do-It-Yourself Lung Model (from the University of Arizona). This activity comes with detailed plans using easy-to-find materials. A perfect way for students to understand how contractions of the diaphragm muscle help to fill the lungs.

Section 37-1: The Circulatory System
The human circulatory system consists of the heart, a series of blood vessels, and the blood that flows through them.
As the blood flows through the circulatory system, it moves through three types of blood vessels—arteries, capillaries, and veins.

Section 37-2: Blood and the Lymphatic System
Red blood cells transport oxygen.
White blood cells attack foreign substances or organisms.
Blood clotting is made possible by plasma proteins and cell fragments called platelets.
A network of vessels called the lymphatic system collects the fluid that is lost by the blood and returns it to the circulatory system.

Section 37-3: The Respiratory System
The respiratory system consists of the nose, pharynx, larynx, trachea, bronchi, and lungs.
Smoking can cause such respiratory diseases as chronic bronchitis, emphysema, and lung cancer.

Quick Lab Hint: The Quick Lab on Page 960 depends upon the student being able to inhale enough carbon dioxide to activate the breathing response. As the textbook explains, this response is much more sensitive to carbon dioxide than it is to oxygen. However, in many cases much of the carbon dioxide generated by the quick lab procedure diffuses away before it can be properly inhaled. Stephen Nellman, a graduate student at UCLA sent me this hint, which seems to make the lab work more effectively:

"I found a better way of performing the lab which gives the desired results. If you fill a flask with water, then drop in the seltzer tabs and quickly cover with a balloon, the CO2 gas fills the balloon. Once the reaction slows, remove the balloon and inhale directly from it. The stimulation to take a breath is immediate."

Use caution, of course, to make sure that students do not inhale so much carbon dioxde that they begin to feel faint (watch them carefully!). However, if the procedure works correctly, even a single breath from the balloon should activate the breathing response.
