The hidden event on the ECG.

The repolarization of the atria. It occurs at the same time as the QRS complex so it doesn't show on the ECG.

Red electrode

Negative - goes on right wrist

Black electrode

Positive - goes on left wrist

Green electrode

Ground - on the right wrist 2 inches above the red electrode

Any vessel that carries blood away from the heart.

Artery

Blood moves slowest in which vessels? Why?

Capillaries. They are small, single-cell capacity and have lower pressure

Agglutinogens

Genetically determined antigens found on the surface of every individual's erythrocytes (RBC)

Agglutinins

Antibodies that will bind with antigens (clumping) in the presence of agglutinogens.

Blood moves fastest in which vessels? Why?

Arteries. They are smaller in diameter but have higher pressure

Any vessel that returns blood from a capillary network back to the heart.

Vein

Tunica Interna

What is B?

Considering a corresponding artery and vein which has a smaller diameter? Why?

Arteries, because they need higher pressure

Agglutination

The clumping of red blood cells, due to an antigen-antibody interaction.

Tunica Media

What is C?

Plethysmograph

An instrument used to measure changes in the size of an organ or the amount of blood flowing through it

What materials were used for blood typing?

■Alcohol prep pad

■Sterile lancets

■Plastic blood typing slide

Vein Tunica Media

What is G?

Volume Pulse

The change in blood volume with each cardiac cycle. It reflects the blood flow in peripheral circulation

Hematocrit

The percentage of packed red blood cells in the total blood volume, that also determines the oxygen carrying capacity of your blood is called the :_____________?

Name the 2 things volume pulse measures

Heart rate: which is done with frequency (frequency = the number of waves)

Amplitude: the height demonstrated in the graph
