Artery

any vessel that carries blood away from the heart

Arteries. They are smaller in diameter and have higher pressure

Blood moves fastest in which vessels? Why?

Agglutinogens

Genetically determined antigens are known as?

Vein

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

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

Blood moves slowest in which vessels? Why?

Agglutinins

The presence of these agglutinogens is determined by testing the erythrocytes with antibodies, known as __________________________, that will bind to the antigens.

Agglutination

If the agglutinogen is present on the erythrocytes there will be an antigen-antibody reaction which causes the red blood cells to clump together, called ___________________________.

Arteries, because they need higher pressure; thicker walls

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

Tunica Interna (artery)

What is B?

Tunica Media (artery)

What is C?

Plethysmograph

An instrument used to measure the amount of blood flowing through an organ.

Hematocrit

The _____________________ is the percentage of the total blood volume that is comprised of the packed red cells.

Tunica Externa (artery)

What is D?

Volume Pulse

The change in blood volume with each cardiac cycle.

40-50%

For men the normal range for hematocrit is?

36-45%

For women the normal range for hematocrit is?

Tunica Externa (vein)

What is F?

Elastic recoil of an artery after the closure of the aortic valve.

Define Dicrotic Notch

Tunica Media (vein)

What is G?

Elastic recoil of the artery after the aortic semilunar valve closes

What occurrence in the body is responsible for the dicrotic notch?

Leukocytes

The _______________________ are responsible for protecting the body against disease.

Tunica Interna (vein)

What is H?

Rising edge corresponds to active contraction and falling edge to relaxation.

Notice that the slope of the rising edge of the volume pulse is much steeper than the slope of the falling edge. Why?

Granulocytes

The _______________________, white blood cells containing cytoplasmic granules, consist of neutrophils, basophils and eosinophils.

Agranulocytes

The _______________________, cells without cytoplasmic granules, consist of monocytes and lymphocytes.
