hemat- (blood) -ology (the study of)

The study of the blood, blood forming organs, and blood diseases

Fluid that transports important substances throughout the body

Contains: Plasma Red Blood Cells White Blood Cells Platelets

A yellow liquid that is 90 % water Contains proteins and clotting factors made by

liver Water levels are controlled by kidneys Water :

1. Takes a lot of energy to heat 2. Is a universal solvent

Transports: Nutrients Hormones Waste Clotting factors (fibrinogen to fibrin)

Swelling caused by water trapped in body tissue

Fragments from a very large cell in bone marrow called megakaryocytes

Essential to clotting Stick to site of wound Release chemicals that turn fibrinogen

to fibrin Fibrin stretches across wound and traps

platelets and red blood cells

Thrombocytopenia – A condition in which there are not enough platelets in the blood.

Causes pin sized bruises all over bodyCan be caused by:

•Damage to bone marrow•Antiplatelet antibodies

Protect the body from infection Produced in bone marrow Have a large lobed nucleus Fewer WBC’s than RBC’s

1. Granulocytes – have granules 2. Macrophages – don’t have granules

Kill damaged cells and disease causing organisms by phagocytosis

-When a cell engulfs material and brings it into its cytoplasm

Leukemia – Cancer in the bone marrow that causes uncontrolled production of WBC’s

Made in bone marrow Has no nucleus Filled with a protein called HEMOGLOBIN (contains

iron) Hemoglobin picks up oxygen in the lungs Transports oxygen to all tissues in the body Picks up Carbon dioxide Transports Carbon dioxide back to lungs

ANEMIA - A condition in which there is either a low amount of RBC’s or working hemoglobin

SICKLE CELL ANEMIA – Defect in hemoglobin structure

that makes crescent shaped RBC’s

Causes painful clots
