Why can't a person with type A safely receive blood from a person with type B blood

Hemophilia

A typical adult hematocrit is

Higher in males than females

Plasma is the closest in ionic composition to

Interstitial fluid

How does a treatment with anti-Rh antibodies (RhoGAM) prevent hemolytic disease of the newborn

It prevents maternal anti-Rh antibodies from crossing the placenta

Aged in damaged erythrocytes are broken down by macrophages in all of the following places except the

Kidney

Which type of white blood cells would you find in the greatest numbers in an infected cut

Neutrophil

The most common form of hemolytic disease of the newborn happens after a _______ woman has carried a _______ fetus

Rh-, Rh +

Why is RhoGAM administered to pregnant Rh women

RhoGAM contains anti-Rh antibodies, which circulate in the mothers' bloodstream to destroy any fetal RBCs there, thereby preventing the mother from making antibodies against the developing fetus's red blood cells.

hemoglobin

Which of the following is not true of basophils

increased production during parasitic infections

pernicious anemia caused by lack of intrinsic factor is specifically treated by

injections of vitamin B12

RBCs typically live about 120 days. The main reason for this short lifespan in RBCs is their

lack a nucleus

Platelets are pinched off from giant multinucleated cells in the bone marrow called

megakaryocytes

During a bacterial infection you would expect to see increased numbers of

neutrophils

The most numerous white blood cells in the peripheral circulation are the

neutrophils

Identify the five types of white blood cells.

neutrophils, eosinophils, basophils, monocytes, lymphocytes
