1. CIRCULATORY AND RESPIRATORY Ipp

2. BLOOD FUNCTION Transports nutrients, O2, CO2, & waste
Defends the body against disease

3. COMPOSITION Plasma: liquid medium
Red blood cells (erythrocytes): transport CO2 and O2
White blood cells (leukocytes): defend against disease
Platelets: form blood clots

4. PLASMA
Made of 90% water, sugar, salts, amino acids, vitamins, minerals
Yellow in color

6. PLATELETS partial cells formed in bone marrow
release chemicals to attract a protein called fibrin to make clots

7. RED BLOOD CELLS most common in the blood made in red bone marrow
made of iron-containing hemoglobin
lack of nucleus leaves space to transport materials

8. WHITE BLOOD CELLS
Form in red bone marrow but mature in the lymph nodes
Many types of white blood cells

9. LYMPHATIC SYSTEM
The human circulatory system processes an average of 20 liters of blood per day
Some fluid gets trapped between cells
The lymphatic system transfers that fluid to the circulatory system
Stores WBCs to fight infections
