Chapter 19

Question 0

45% of blood. Made up of platelets, WBCs, and RBCs

Answer 0

Formed elements

Question 1

Made of water and proteins such as albumins, globulins, and fibrinogen. 55% of blood

Answer 1

Blood plasma

Question 2

Platelets have a _______ life span of ___ to ____ days.

Answer 2

Short, 8 to 10

Question 3

Hormone produced by the liver that stimulates the formation of platelets from megakaryocytes.

Answer 3

Thrombopoietin

Question 4

Process by which the formed elements of blood develop.

Before birth, this occurs in sac of embryo. But red bone marrow becomes the primary site.

Answer 4

Hematopoiesis

Question 5

Increases the number of red blood cell precursors. Produced primarily by cells in kidneys. If kidneys fail, RBC production is inadequate. Bad hematocrit-> no O2 to body tissues.

Answer 5

Erythropoietin

Question 6

Store, accumulate, and pass along o2 very well. Floppiness allows them to flow through capillaries.

Don’t have nucleus, can’t produce proteins, not really living cells, die in abt 120 days. 4-6 mil per microliter

Answer 6

Red blood cells

Question 7

Immature RBCs. Low count indicates low erythropoietin rate. Elevated rate vise versa. As the cell matures, the nucleus disappears, and amt of hemoglobin increases.

Answer 7

Reticulocytes

Question 8

This is packed inside RBC. Carries o2 and co2. Each RBC contains 280 mil molecules of hgb

Answer 8

Hemoglobin

Question 9

Excess RBCs

Answer 9

Polycythemia

Question 10

Weird shaped cells by beta globins

Super bad…

Answer 10

Sickle cell anemia

Question 11

Loss of lots of blood can lead to this

Answer 11

Hemorrhagic anemia

Question 12

Insufficient RBCs, or hemoglobin

Answer 12

Anemia

Question 13

WBC that fights bacterial infection. Is active in phagocytosis.

Answer 13

Neutrophil

Question 14

WBCs that increase during parasitic infection.

Answer 14

Eosinophils

Question 15

WBCs present in histamine reactions. Big role in inflammatory response.

Answer 15

Basophils

Question 16

Not granulocytes. They are phagocytes.

Answer 16

Monocytes

Question 17

WBCs that aren’t granulocytes. Increase in acute viral infections. Responders to specific foreign antigens. Nucleus takes up whole cell.

Answer 17

Lymphocytes

Question 18

Process that stops bleeding

Answer 18

Hemostasis

Question 19

Occurs as damaged blood vessels constrict.first stage of hemostasis

Answer 19

Vascular spasm

Question 20

Platelets adhere to endotherm that’s damaged. Second stage of hemostasis.

Answer 20

Form platelet plug

Question 21

Blood clot. 3rd stage of hemostasis

Answer 21

Coagulation

Question 22

2 pathways to coagulation cascade

Answer 22

Intrinsic and extrinsic

Question 23

Clotting in an unbroken blood vessel

Answer 23

Thrombosis

Question 24

The clot itself

Answer 24

Thrombus

Question 25

Drugs that stop/ reverse thrombosis

Answer 25

Anticoagulants (rat poison) | platelet inhibiting drugs. Aspirin like

Question 26

Thrombus breaking loose ( embolus), can lead to....

Answer 26

Stroke

Question 27

Baby can't clot. Hereditary genetic disorder.

Answer 27

Hemophilia

Question 28

Blood coagulates almost instantly. Found in shrimp shells. Parasitic infection.

Answer 28

Chitosan patches (hemostatic bandage)

Question 29

Used for diagnostic testing bc it won't coagulate in machine

Answer 29

Serum
