during periods of fasting

A plasma protein essential in blood coagulation is

fibrinogen

In adults, red bone marrow is located in the

iliac crest sternum and ribs body of vertebrae proximal epiphyses of long bones.

Which of the following combinations may result in the hemolytic disease of the newborn

mother Rh negative, and baby Rh positive

What do B lymphocytes do?

produce antibodies in response to antigens

People with type AB blood are considered the "universal recipient" for transfusions because

their blood lacks A or B agglutinins.

Each hemoglobin molecule contains

4 iron atoms

Eileen is a strict vegan and therefore eats no animal products. She develops an anemia that her doctor thinks is caused by a nutritional deficiency. Which of the following is the likeliest candidate?

Vitamin B12 deficiency

The disease sickle cell anemia is an example of what can happen if

a gene for adult hemoglobin is abnormal.

Which of these is not one of the formed elements of blood

antibodies

What do T lymphocytes do?

are involved in cell mediated immunity

The function of hemoglobin is to

carry dissolved blood gases

________ involves a cascade of reactions leading to the conversion of fibrinogen to fibrin.

coagulation

A moving blood clot is called a(n)

embolus

White blood cells that are increased in allergic individuals are

eosinophils

red blood cell production is regulated by the hormone

erythropoietin

The yellow color that is visible in the eyes and skin in jaundice results from

excessive amounts of bilirubin in the plasma extensive breakdown of RBCs the recycling of hemoglobin destruction of hemoglobin.

Some rat poisons contain a toxin that blocks the liver's ability to utilize vitamin K. Animals that consume this poison would die of

hemorrhage

Thyroid-binding globulin is an example of which kind of plasma protein?

hormone-binding

plasma protein essential in body defense are the

immunoglobulins

Each heme ring in hemoglobin encloses an atom of

iron

Which organ secretes most of the plasma proteins

liver

If bile ducts are blocked...

more bilirubin appears in the plasma

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

neutrophils

Areas in a vessel wall where large quantities of lipid accumulate are called

plaques

All of the circulating red blood cells in an adult originate in the

red bone marrow

In adults, erythropoiesis exclusively takes place in

red bone marrow

What are common sources of vitamin K?

whole grains organ meats intestinal bacteria green vegetables

What are the functions of blood

transport of gases transport of nutrients and wastes transport of body heat defense against toxins and pathogens

The most abundant form of plasma is

water

The combination of plasma and formed elements is called

whole blood

The percent fraction of formed elements relative to whole blood is the

Hematocrit

Plasma is closest in composition to

Interstitial fluid

Aged and damaged erythrocytes are broken down by macrophages in the

Spleen, liver and bone marrow

A hematocrit provides information on

sedimentation rate

When a person who lives at sea level vacations in the Rocky Mountains, you would expect

the release of erythropoietinan increase in red blood cell production a drop in oxygen levels a rise in hematocrit.
