1. Circulatory System
BLOOD

2. The Blood Body contains 4-6 L Consists of Water Red Blood Cells Plasma
White blood cells and platelets

3. Whole Blood Sample Plasma Platelets White blood cells Red blood cells

6. Your Blood: Fluid Transport
Liquid Portion (Plasma) Carries
Blood cells
Erythrocytes (RBC - red blood cells)
Leucocytes (WBC - white blood cells)
Platelets (non cellular particles)
Proteins
Enzymes
Hormones – Endocrine System
Nutrients - Digestive System
Gases - Respiratory System
Inorganic salts

7. Oxygen in the Blood Oxygenated Blood
Hemoglobin, iron containing molecule
Loosely picks up oxygen in the lungs
Loses oxygen in areas low in oxygen (diffuses)

8. What does blood contain?
50% Water
45% Erythrocytes (RBC)
4% Plasma with Substances
1% Leukocytes (WBC) + Platelets

9. Erythrocytes (RBC) Transporters of RBC
Oxygen
Carbon Dioxide
RBC
Lack a nucleus
Contain hemoglobin
Disk-shaped
RBC are produced in red bone marrow of
ribs,
humerus,
femur,
sternum, and other long bones
Lives for 120 days

10. Leukocytes (WBC) WBC fight infection/disease Less abundant Large cells
Attack foreign substances
Less abundant
Large cells
Some live for months
Most just a few days
ALL contain nuclei

11. Platelets PLATELETS are for CLOTTING blood Cell fragments
Produced in bone marrow
Short life span (1 week)
Fibrin (sticky network of protein fibers)
Form a web trapping blood cells

12. Break in Capillary Wall
Blood Clotting
Break in Capillary Wall
Clumping of Platelets
Clot Forms

13. Blood Types Massive loss of blood requires a transfusion Four TypesAB O
Rhesus factor (Rh)
Rh+ (have antigen)
Rh- (NO antigen)
Inherited from your parents

14. Blood Types
Plasma contains proteins that correspond to the shape of the different antigens
If you mix one type with the wrong one, you get CLUMPING
Type O is the universal donor
Type AB is the universal acceptor
