| Question | Answer |
|---|---|
| What are the two systems of the circulatory system? | blood-vascular & lymphatic system |
| - major part that transport blood | blood-vascular system |
| - minor system that collects fluid, or lymph, from the tissue spaces | lymphatic |
| What are the functions of the circulatory system? | carry oxygen and nutritive material to the tissues; collect and transport carbon dioxide and other metabolic wastes to the organs of excretion |
| - central organ of blood vascular system | heart |
| What are the four chambers of the heart? | two atria and two ventricle |
| What divides the atria from ventricles? | septum |
| - muscular wall of the heart | myocardium |
| - inner lining of the heart | endocardium |
| - thin membrane that covers the heart | epicardium |
| - double-walled outermost covering of the heart | pericardial sac |
| What does the right side of the heart handle? | venous or deoxygenated blood |
| What does the left side of the heart handle? | arterial or oxygenated blood |
| - supply blood to the myocardium of heart | coronary arteries |
| - the general term referring to radiologic examination of vascular structures after the introduction of a contrast medium | angiogrpahy |
| - refers to the radiologic examination of arteries via contrast injection | arteriography |
| - refers to the radiologic examination of veins via contrast injection | venography |
| What type of contrast media is most common? | water-soluble iodinated medium |
| What are two reason nonionic contrast mediums are used? | fewer physiologic side effects, less nephrotoxic |
| - still used in cardiac catheteriazation procedures to prvide images in a movie IR format | cinefluorography |
| - most widely used method of catheterization | seldinger technique |
| What is the most common site for injection? | femoral artery |
| There are fewer possibilities of thrombosis formation with ____________ versus a catheterization technique. | direct puncture |
| - captures 3D images by simultaneous exposures from two planes | bi-plane |
| What are the four major arteries that supply the brain? | R and L common carotids and R & L vertebral arteries |
| Injection site for the upper limb venography is usually in? | into a superficial vein in the hand or wrist and images are obtained up to the area of the superior vena cava |
| Why are upper and lower limb venography preformed? | used to visualize thrombophlebitis, varicose veins, or vessel damage secondary to trauma |
| For a lower limb venogram, how is the pt positioned? | semi-erect position ( 45 deg if possible) |
| For a lower limb venogram, where is the contrast injected? | superficial vein in the foot |
| For a lower limb venogram,where do you begin imaging? | at the ankles and proceed superiorly to include the inferior vena cava |
| What artery does the right common carotid artery branch off of? | brachlocephalic artery |
| What artery does the right subclavian artery branch off of? | brachlocephalic artery |
| Right coronary artery branches off of what? | aorta |
| Left coronary artery branches off of what? | aorta |
| Lt common carotid artery and lt subclavian artery both branch off of? | aorta |
