RED BLOOD CELLS

white blood cellswhite blood cells•fight disease

•larger than red

blood cells

•live for months or years

In this electron micrograph, a In this electron micrograph, a human white blood cell is human white blood cell is trapping bacterial cellstrapping bacterial cells.

plateletsplatelets• cell fragment

• blood clotting

• release fibrin= chemical that weaves net of tiny fibers across wound

blood transfusion• transfer of blood from

person person

blood types• 4 types:• determined by marker molecules

1. A = have A marker

2. B = have B marker

3. AB = both A & B

4. O = neither A nor BBlood Types

Rh factor• Rh positive- have marker

• Rh negative- do not

system thru. capillaries

lymphatic system

• network of veinlike vessels that connects to veins in chest empties lymph bloodstream

(plasma)

lymph node• small knob of tissue that filters lymph

• trap disease causing organisms
