Cardiovascular- NU 327
Main goal of circulatory system- - ANS--Transport O2 and nutrients
-Removal of metabolic waste products within the body

Right ventricle pumps blood - - ANS-To the lungs

O2 intake and release of CO2 occurs - ANS-In the pulmonary vasculature

Left ventricle pumps blood - ANS-Systematically

Nutrients are absorbed in the blood as it - ANS-Moves through the GI tract

Where is waste carried? - ANS-Lungs/kidneys/liver for elimination

Aorta-> Arteries -> Aterioles - ANS-Principle tissue is smooth muslce

Capillaries - ANS-Single layer of endothelial cells

Venules -> Veins -> Superior vena cava - ANS-Principle tissue is connective tissue

Characteristics of vessels - ANS-1.Begin blindly (not in a circuit)
Deep in connective tissue

2.Reabsorbs fluid that leaks out of vascular network
Returns to general circulation

Intima (3 layer structure) - ANS-Layer of endothelial cells
Direct contact with blood

Media (Three layer structure) - ANS-Smooth muscle and elastin
Thicker in arteries

Adventitia (3 layer structure) - ANS-Supportive connective tissue

Extrensic (control of BF) - ANS-Vasoconstriction
Symathetic nervous system (smooth muscle)

Norepinephrine- - ANS-One of the catecholamines

Intrinsic- - ANS-Autoregulation
Maintaining a constant flow regardless of changes in arterial pressure

, Blood clots composed of - ANS-Aggregated platelets
Clotting factors
Fibrin
(adhere to vessel wall)

Blood clots form where? - ANS-1.In chambers of the heart (dysrythmia, valve damage or
replacement)

2.Form in arterial or peripheral circulatory system

3.From dehydration or drugs

Pathogenesis of blood clots: - ANS-1.Arterial- May reduce flow (turbulence)
Distal ischemia

2.Venous-Clot alters venous return
Impairs removal of metabolic waste
Produces swelling (edema)
If inflammation occurs (phlebitis) causing a thrombusthrombophlebitits

Clinical manifestations of thrombus - ANS-1.Arterial- intermittent claudication*
Cool to touch
Cyanotic
Arterial ulcer-late

2.Venous-May be asymptomatic to life threatening (PE)
Calf or groin tenderness
Swelling
Increased skin temp
Homan sign (10%)

Treatment of thrombus: - ANS-PREVENTION!
1.Medical: oral or parental coagulants
Drugs to block platelet aggregration
Antiembolic stockings
Sequential compression devices (SCDs)
Early ambulation

2.Surgical: Removal of the thrombus

Blood vessel obstructions
Embolus-traveling blood clot etiology: - ANS-1.Dislodged thrombus from heart
From aorta in cerebral artery (stroke)
