Question 15

Coronary angioplasty

Answer 15

Insertion of a small balloon catheter into the lumen of the coronary artery. Inflated to flatten the obstructing plaque against the wall, improves blood flow.

Question 24

Pulmonary trunk

Answer 24

Exits heart at superior border
distal the R ventricle past the pulmonary valve
Produces the R and L pulmonary a. which travel with a corresponding bronchus and similar branching pattern

Question 25

R and L pulmonary a.

Answer 25

Branch of pulmonary trunk from R ventricle of the heart Enters lung at hilum Thick walls convey deoxygenated blood

Question 26

Pulmonary embolism

Answer 26

Obstruction of pulmonary a. by an embolus, such as blood clot, fat globule or air bubble. Usually passes from a vein into the R side of the heart into the pulmonary a.

SVC

Answer 28

Superior vena cava Union of R and L brachiocephalic v. and azygous v. Drains from superiorly into R atrium

Question 29

IVC

Answer 29

Inferior vena cava Union of R and L common iliac v Travels through the abdomen, through the vena caval foramen of the thoracic diaphragm and then drains from inferiorly into R atrium

Question 30
