Levels of Organisation
Name the 10 organ systems
Components of the Circulatory System1. Blood Plasma : Aqueous solution containing minerals, vitamins, glucose and proteins eg clotting agents.2. Blood Cells : Erythrocytes, Leucocytes, Platelets.3. Heart : A “pump”4. Blood Vessels : Arteries, Veins, Capillaries
Capillary “Bed” / Complex
Roles of the Cardiovascular System1. Transport : a) Oxygen and Carbon Dioxide b) Waste materials eg Urea c) Hormones “Chemical Messengers” d) Nutrients
2. Thermoregulation : a) Vasoconstriction b) Vasodilation
3. Body Defence a) Blood Clotting b) Leucocytes (Phagocytes) c) Immune Response
Double Circulation Single Circulation
Circulatory System
Differential Diagnosis : Haematology Test
HCT : % RBC in a blood sample HGB : Hamoglobin in a sample of blood
MCV : RBC Volume (volume of the individual RBC) eg Low = iron deficiency MCHC : Concentration of haemoglobin in a blood cell
Blood Biochemistry
BUN : Blood Urea Nitrogen - High = Kidney damage
ALKP, GGT : Liver enzymes - High – Liver damage.
Albumen (ALB) : Blood protein made by the liver – Low – Liver damage.
