The total volume of blood in the body of an adult male is approximately ________ liters.

5-6

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

Coagulation

The superior vena cava collect blood from the

Head, chest, and upper limbs

________ transport(s) oxygen and CO2 in the RBCs.

Hemoglobin molecules

Overall, the most common blood type is

O

A person with Type A blood has

antigen A on the RBCs and anti-B antibodies in the plasma

White blood cells that release histamine at the site of an injury are

basophils

The function of hemoglobin is to

carry oxygen

The function of red blood cells is to

carry oxygen from the lungs to the body's cells.

The ________ is a procedure that is used to determine the number of each of the various types of white blood cells.

differential count

White blood cells that are increased in individuals with allergic reactions are the

eosinophils

The process of red blood cell production is called

erythropoiesis

Red blood cell production is regulated by the hormone ________ which is mostly produced in the ________.

erythropoietin; kidneys

Capillaries with a perforated lining are called

fenestrated capillaries

A hematocrit provides information on

formed elements abundance

Each hemoglobin molecule contains

four iron ions

What are discontinuous capillaries

have a wide diameter

The waste product bilirubin is produced from

heme molecules lacking iron

More than 95 percent of the protein in a red blood cell is

hemoglobin

A typical adult hematocrit is

higher in males than females.

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

lack of nucleus

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

neutrophils

Type O+ blood cannot be given to a type __________ recipient.

o-

A person's blood type is determined largely by the

presence of specific glycoproteins on the cell membrane

As blood travels from arteries to veins,

pressure drops

Most of the iron that is removed from degraded hemoglobin is

recycled to red bone barrow

All the circulating red blood cells originate in the

red bone barrow

In adults, erythropoiesis exclusively takes place in

red bone barrow

Sensitization during hemolytic disease of the newborn refers to

the mother's immune system producing antibodies against the fetus' RBCs

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

their blood lacks A or B antibodies.

If the blood types of a donor and recipient are compatible, then

there is no reaction between antibodies and antigens

The conversion of fibrinogen to fibrin is catalyzed by

thrombin

Which of the following is the innermost layer of a blood vessel?

tunica intima

Which blood type contains RBCs with surface antigen B only and plasma that contains only anti-A antibodies?

type b

The large vessels that return blood to the heart are called

veins

The combination of plasma and formed elements is called

whole blood.

how many blood types are there

8

A person with type AB blood has _______.

A and B antigens and neither anti-A nor anti-B antibodies

Which of the following proteins functions to store or transport oxygen?

hemoglobin

What is sickle cell anemia?

a deficiency in red blood cell hemoglobin.

The most abundant proteins in blood plasma are

albumins.

Hemolytic disease of the newborn may result if

an Rh-negative mother carries an Rh-positive fetus.

After donating 0.5 liter of blood, one would expect

an increased reticulocyte count
