Blood consists of...

Plasma, red blood cells, white blood cells, and platelets

1

How much blood in adults

5 liters (70ml/kg) in males
65ml/kg in females

2

Plasma

Watery fluid that accounts for more than half of the total blood volume. 92% water, 8% dissolved substances

3

Erythrocytes

Red blood cells. Carries oxygen to the cells. Propelled by plasma. Contain hemoglobin.

4

Hemoglobin

In red blood cells. Binds oxygen absorbed in the lungs.

5

Erythropoiesis

The process that makes red blood cells.

6

Microphages

Cells that protect the body against infection.

7

Bilirubin

RECYCLING PARTS OF HEMOGLOBIN. Leftover parts of the hemoglobin that are not destroyed, is converted into bilirubin... Which undergoes further metabolism in the liver.

8

Antigens

Proteins recognized by the immune system.

9

Antibodies

Proteins that react with antigens .

10

Blood typing

Classified based on the presence or absence of specific antigens. Four blood types.

11

Anemia

Decrease in the he number of red blood cells.

12

Erythroblastosis fetalis

During late pregnancy and delivery... The mother and fetus may have different Rh positives/negatives. Mothers body's will produce antibodies to the antigens, which may enter the fetal circulation and destroy the fetus red blood cells.

13

Leukocytes

White blood cells
Fight infections.
Larger than red blood cells

14

Diapedesis

Allows white blood cells (leukocytes) to leave the blood vessels and go to the tissues where they may be needed.

15

Two types of leukocytes...?

Granulocytes
Agranulocytes

16

Neutrophils

Most common type of granulocytes.
Polymorphonuclear cells (polys).
DESTROY BACTERIA

17

Eosinophils

Function in allergic responses.

18

Basophils

Play a role in allergic and inflammatory reactions.
Contain large amounts of histamine .

19

Histamine

Substance that increases tissue inflammation.

20

Heparin

Substance that inhibits blood clotting

21

Lymphocytes

Smallest of the Agranulocytes.
Most originate in the lymph nodes.

22

Monocytes

Respond to infections and are thence first line of defense in the inflammatory process

23

Platelets

Cells within the blood.
Essential for clot formation.

24

Hemostasis

Cessation of bleeding... The process in he hitch bleeding stops and a final clot is formed.

25

Fibrin

Binds to the platelet plug ( aggregated platelets cause an initial plug to stop bleeding) to create the final mature clot.

26

Tissue plasminogen activator

"T-Pa"
Counterbalances they clotting system.
