Cardiovascular system
•What makes up blood•How blood is grouped and typed•A simple look at how blood clots
•The heart chambers and how the blood flows through the heart•The pulmonary circulation and the systemic circulation•Blood pressure, pulse rates.•Some pathologies related to blood, heart and circulation.

Blood: 45% Formed Elements
Formed elements: White blood cells - clear ‘Buffy layer’
4-11,000wbc per mm volume of blood Platelets
250,000 – 500,000 platelets per mm vol of blood
Red blood cells – 99% 4-6 million rbc per mm vol of blood
1000rbc : one wbc

Blood Typing - ABO
Type O is universal donor

Hemostasis(clotting)
Stage summary
Stage 1Vasoconstriction
Vascular spasms cause vessel to shrink – closing edges Chemicals released from damaged vessel wall activate next stage. Clotting factors released.
Stage 2Platelet Plug(mechanical )
Collagen exposed in damaged vessel wall stimulates platelet stickiness – plug formed by layers of platelets sticking together and to collagen. (Thrombus).
Stage 3Coagulation stage(chemical)
Thrombin converts fibrinogen to fibrin – the mesh of the clot. Factor 13 stops the clotting cascade from continuing.
