Classification of Blood Cell Flashcards
Blood Function
Transports materials to and from body tissue
Blood Transports to Tissues
Oxygen, Nutrients, Hormones, Water and Heat
Blood Transports From Tissues
Waste Matter and Carbon Dioxide
Erythrocyte Primary Function
Transports Oxygen (>1 billion) to blood tissues
Main Oxygen Carrying Molecule in Erythrocytes
‘Haem’ contains iron
Erythrocyte Shape
Biconcave with no nucleus. More flexible
Haemoglobin Composition
Globin protein (4 folded (alpha and beta) peptide chains , 4 Haem groups (non-protein complexes containing iron)
Oxyhaemoglobin
Haemoglobin with oxygen bound to it
Role of leukocytes in Immune System
Defends against pathogens, identifies cancer cells, removes dead/cancerous cells from body
5 Types of Leukocyte
Neutrophil, Eosinophil, Basophil, Monocye, lymphocyte
Polymorphonuclear (many shapes of nucleus) granulocytes (65% of white blood cells)
Neutrophil, Eosinophil, Basophil
Mononuclear Agranulocytes (35% WBC)
Monocyte and Lymphocyte
Neutrophil Function
Phagocyte. High levels in blood indicates bacterial infection
Eosinophil Function
Combats parasitic and viral infections aswell as allergy response. High levels indicate an allergic reaction/parasitic infection
Basophil Function
Synthesises and stores histamine (vasodilation) and heparin (anti-coagulant)
Monocyte Function
Phagocytosis of bacteria and removal pf aged erythrocytes
