What are the 2 types of ciruclation in the heart?
1. Pulmonary Circulation 2. Systemic Circulation
What does Pulmonary Circulation do?
Pulmonary Circulation carries DEOXYGENATED blood from the Right Ventricle to the lungs.
What does Systemic Circulation do?
Systemic Circulation carries OXYGENATED blood from the Left Ventricle throughout the body.
What are the 2 RIGHT valves of the heart?
1. Tricuspid Valve: atrioventricular valve 2. Pulmonic Valve: semi-lunar valve
What are the 2 LEFT valves of the heart?
1. Mitral Valve: atrioventricular valve 2. Aortic Valve: semi-lunar valve

What does the formed elements (celluar portion of blood) consist of?
erythrocytes, leukocytes, thrombocytes
What is the lifespan for Erythrocytes?
What are the 5 leukocytes (white blood cells)?
1. Neutrophils 2. Lymphocytes 3. Monocytes 4. Eosinophils 5. Basophils
What is another name for Leukocytes?
White Blood Cells
The process by which the blood vessels are repiared after injury.
What are the 4 stages of Hemostasis?
1. Vascular Stage 2. Platelet Phase 3. Coagulation Phase 4. Fibrinolysis
Explain the Vascular Phase of Hemostasis.
1st step in Hemostasis. Injury to blood vessels, causing it to constrict and slowing the blood flow.
Explain the Platelet Phase of Hemostasis.
2nd step in Hemostasis. Platelets adhere to injured endothelial lining. This forms aggregation (temporary platelet plug).
A temporary platelet plug formed during the platelet phase of hemostasis.
Explain the Coagulation Phase of Hemostasis.
3rd Step in Hemostasis. Converts temporary platelet plug into a stabin fibrin clot.
Explain Fibrinolysis in Hemostasis.
4th Step in Hemostasis. Breakdown and removal of the stabin fibrin clot.
What does APTT stand for?
Activated Partial Thromboplastin Time
What is APTT used to monitor?
APTT montiors Heparin Therapy and intrinsic pathways.
What does PT stand for?
What is PT used to monitor?
PT monitors Coumadin Therapy, as well as extrinsic pathways.
What are the 3 major beins located in the antecubital fossa that are acceptable to use for a VP?
1. Median Cubital Vein 2. Cephalic Vein 3. Basilic Vein
Vein of choice for a VP. A large vein that tends not to move.
Median Cubital Vein.
2nd vein of choice for a VP. This vein has tendency to move. It is often the only vein that can be palpated in an obese patient.
3rd vein of choice for a VP. Tends to move.
