Q

How much blood in adults

A
5 liters (70ml/kg) in males
65ml/kg in females
1
Q

Blood consists of…

A

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

2
Q

Plasma

A

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

3
Q

Erythrocytes

A

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

4
Q

Hemoglobin

A

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

5
Q

Erythropoiesis

A

The process that makes red blood cells.

6
Q

Microphages

A

Cells that protect the body against infection.

7
Q

Bilirubin

A

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
Q

Antigens

A

Proteins recognized by the immune system.

9
Q

Antibodies

A

Proteins that react with antigens .

10
Q

Blood typing

A

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

11
Q

Anemia

A

Decrease in the he number of red blood cells.

12
Q

Erythroblastosis fetalis

A

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
Q

Leukocytes

A

White blood cells
Fight infections.
Larger than red blood cells

14
Q

Diapedesis

A

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

15
Q

Two types of leukocytes…?

A

Granulocytes

Agranulocytes

16
Q

Neutrophils

A
Most common type of granulocytes.
Polymorphonuclear cells (polys). 
DESTROY BACTERIA
17
Q

Eosinophils

A

Function in allergic responses.

18
Q

Basophils

A

Play a role in allergic and inflammatory reactions.

Contain large amounts of histamine .

19
Q

Histamine

A

Substance that increases tissue inflammation.

20
Q

Heparin

A

Substance that inhibits blood clotting

21
Q

Lymphocytes

A

Smallest of the Agranulocytes.

Most originate in the lymph nodes.

22
Q

Monocytes

A

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

23
Q

Platelets

A

Cells within the blood.

Essential for clot formation.

24
Q

Hemostasis

A

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

25
Q

Fibrin

A

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

26
Q

Tissue plasminogen activator

A

“T-Pa”

Counterbalances they clotting system.
