Cardiovascular

Front 1

Diapedesis

Back 1

the passage of blood cells through intact blood vessel walls into the tissues.

Front 2

Hematocytoblast

Back 2

stem cell that gives rise to all formed elements of blood, are highly mitotic.

Front 3

Hematopoiesis

Back 3

formation of blood cells

Front 4

Prothrombin

Back 4

a blood clotting protein produced by the liver. inactive form.

Front 5

Granulocytes

Back 5

leukocytes that have cytoplasmic granules of chemicals that are responsible for their function. three types: neutrophils, basophils & eosinophils.

Front 6

Chemotaxis

Back 6

chemical is gonna attract cell to move in a particular direction

Front 7

Antibodies

Back 7

specialized proteins that provide immunity against specific antigens and are produced by B-Cells

Front 8

Fibrinogen

Back 8

a protein in the blood that is converted to fibrin during clotting. inactive form. produced by liver.

Front 9

Albumin

Back 9

the most abundant protein found in the plasma; helps with osmotic pressure and is a buffer. produced by the liver.

Front 10

Solutes

Back 10

dissolved substances in a solution

Front 11

Formed Element

Back 11

the cellular portion of the blood

Front 12

Anemia

Back 12

reduced oxygen carrying capacity of blood that is caused by a decrease number of RBCs or a decreased % of hemoglobin in the blood. iron deficiency

Front 13

Agranulocytes

Back 13

leukocytes that LACK stainable granules. two types: monocytes & lymphocytes

Front 14

Neutrophils

Back 14

Structure:
granulocyte
most numerous

Function:
first to site of infection
kills oxidizing substances

Front 15

Eosinophils

Back 15

Structure:
granulocyte

Function:
to kill parasitic worms by releasing an enzyme that digests worms surface

Front 16

Basophils

Back 16

Structure:
granulocyte

Function:
-inflammation
-has compound histamine
-histamine causes BV walls to become leaky and acts as an attractant
-histamine is attracted to other WBCs

Front 17

Thrombocytes

Back 17

Structure:
cellular fragments (cell membrane and cytoplasm pieces)

Function:
blood clotting

Front 18

Monocytes

Back 18

Structure:
agranulocyte
phagocyte

Function:
migrate to body tissues as needed

Front 19

Erythrocytes

Back 19

Structure:
biconcave discs
filled with hemoglobin
no nucleus

Function:
carry oxygen and carbon dioxide

Front 20

Lymphocytes

Back 20

Structure:
most abundant agranulocyte
reside in lymphatic tissues

Function:
IMMUNITY!
B-Cells: produce antibodies
T-Cells: fight viral infections and cancer cells. responsible for tissue rejection.

Front 21

Leukocytes

Back 21

Structure:
granulocytes
agranulocytes

Function:
DEFENSE!!
Diapedesis
Chemotaxis

Front 22

Where does blood formation occur in adults?

Back 22

Occurs in the red bone marrow of the spongy bone.

Example: flat bones and the ends of long bones.

Front 23

Thrombocyte Formation

Back 23

Results from the megakaryocytes pinching off a bit of cell membrane and cytoplasm. The process is stimulated by the hormone thrombopoieten.

Front 24

Erythrocyte Formation

Back 24

Erythrocytes are continuously being produced. As they age or become worn out, they are eliminated by phagocytes. When oxygen becomes low in the blood, the kidney releases a hormone called erythropoieten which stimulates the formation of more RBCs.

Front 25

Leukocyte Formation

Back 25

Controlled by the hormones CSF and IL. CSF is colony stimulating factor and IL is interleukins. Chemical signals like inflammation, bacteria and toxins release the CSF and IL so leukocytes can from.

Front 26

Function of a stem cell

Back 26

to give rise to all formed elements of blood; highly mitotic

Front 27

Interstitial Fluid

Back 27

the fluid between the cells of body tissues

Front 28

Fibrous Pericardium

Back 28

the outer layer of the pericardial sac

Front 29

Agglutination

Back 29

clumping of foreign cells, induced by cross-linking of antigen-antibody complexes

Front 30

Antibody

Back 30

specialized substance produced by the body that can provide immunity against a specific antigen

Front 31

Antigen

Back 31

any substance including toxins, foreign proteins, or bacteria that when introduced to the body is recognized as foreign and activates the immune system

Front 32

Blood flow in arteries are maintained by ???

Back 32

heart contractions

Front 33

vascular spasms cause the ___________ to constrict

Back 33

smooth muscle OR tunica media

Front 34

Cardiac Cycle

Back 34

one complete heart beat

Sinoatrial Node

Back 35

pacemaker
