Define blood pressure
Pressure exerted on the walls of blood vessels, specifically arteries

Factor XII is part of this pathway.
Intrinsic
The order of the path of electrical conduction pathway in the heart

Factors that can affect Cardiac Output
Stroke Volume and Heart Rate
Extrinsic pathway of coagulation is initiated by
Tissue Damage outside of the blood vessels; TF (Factor III)
Blood vessel that carry deoxygenated blood to lungs.
Blood vessel that carry oxygenated blood to heart.
pulmonary arteries; pulmonary veins
Calcium is released from _____ in this myocardial contractile cells

This protein is converted into fibrin in the common pathway to stabilize the clot.
Fibrinogen
3 Factors that affect stroke volume
1. Preload (venous return)
2. Contraction (Ca+2 availability)
3. Afterload (resistance)
4 steps to hemostasis
1) injury 2) vascular spasm 3) platelet plug 4) coagulation

papillary, chordae tendineae, AV valves, S1
What is the role of the Na+/K+ pump in the cardiac action potential?
It helps it get back to resting membrane potential (RMP).
Vasodilation of arteries results in ______
decreased blood pressure; faster blood flow
Test tubes may be lined with this to stop clotting after blood collection.
heparin
