a & P chapter 19 blood

________ are large phagocytic white cells that spend most of their time outside the blood as fixed and free phagocytic cells.

Monocytes

Which of these descriptions best matches the term T lymphocytes?

They are responsible for cell-mediated immunity

The process of fibrinolysis

dissolves clots.

White blood cells that are increased in allergic individuals are the

eosinophils.

The process of red blood cell production is called

erythropoiesis.

The waste product bilirubin is produced from

heme molecules plus iron.

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

hemoglobin.

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

megakaryocytes.

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

neutrophils.

A person's blood type is determined largely by the

presence of specific glycoproteins on the cell membrane.

Which of these descriptions best matches the term B lymphocytes?

produce antibodies in response to antigens

In adults, erythropoiesis exclusively takes place in

red bone marrow.

Aged and damaged erythrocytes are broken down by the

spleen, liver, and bone marrow.

In adults, red bone marrow is located in the

sternum and ribs and iliac crest, body of vertebrae only

________ are immature erythrocytes that are present in the circulation.

. Reticulocytes

Erythropoiesis is stimulated when

. both oxygen levels in the blood decrease and blood flow to the kidney declines.

The chief differences between plasma and interstitial fluid involves the

. concentration of proteins.

Red blood cell production is regulated by the hormone

. erythropoietin.

Most of the iron that is removed from degraded hemoglobin is

. recycled to the red bone marrow.

All the circulating red blood cells originate in the

. red bone marrow.

Granulocytes form in

. red bone marrow.

The conversion of fibrinogen to fibrin is catalyzed by the enzyme

. thrombin.

The most abundant component of plasma is

. water.

The average lifespan of a red blood cell is

4 months.

Which of the following is a function of the blood?

a. transport of nutrients and wastes b. transport of body heat c. transport of gases d. defense against toxins and pathogens e. all of these

The most abundant proteins in blood plasma are

albumins.

Platelets are

cytoplasmic fragments of large cells.

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

basophils.

The function of red blood cells is to

both carry carbon dioxide from the cells to the lungs and carry oxygen from the lungs to the body's cells

The function of hemoglobin is to

carry oxygen and carry carbon dioxide only

Most of the protein factors that are required for clotting are synthesized by

the liver.

Which of the following vitamins is needed for the formation of clotting factors?

vitamin K

The combination of plasma and formed elements is called

whole blood.
