BIOD 152- Module 4 Exam With Satisfied Solutions
Infarction - -blood vessel is entirely blocked
-causes tissue death in that area
myocardial infarction (MI) - -portion of heart that dies due to lack of oxygen
-if partially blocked: causes angina & radiating pain in left arm
-other symptoms: shortness of breath, lightheadedness, pain in arm, jaw, neck, btwn
shoulder blades, chest pressure
Drugs for Thromboembolism - -streptokinase: produced by bacteria
-t-PA: genetically engineered
These convert plasminogen into plasmin which dissolves clots
-Aspirin will reduce coagulation aka it is preventative
Angioplasty - -surgical intervention for thromboembolism
-surgeon threads a plastic tube into te artery arm or leg, tube is then guided through the
blood vessel toward the heart, When the tube reaches the segment clogged by plaque in a
coronary artery, the balloon attached to the end of the tube is inflated, forcing the vessel
open
Coronary Artery Bypass Graft (CABG) - -surgical intervention for thromboembolism

Coronary Artery Bypass Graft (CABG) - -surgical intervention for thromboembolism
-a segment of another blood vessel from the patient's body is stitched to one end of the
aorta and the other end to a coronary artery past the point of obstruction. Once the heart is
exposed, some physicians may also use lasers to open clogged coronary vessels
Arterioles - -controlled by autonomic nervous system
-responsible for peripheral resistance (varying blood pressure changed by external &
internal conditions)
What is the difference between arteries and veins - -Arteries: carry blood away from the
heart, thick elastic walls, has a pulse,
-veins: carry blood to the heart, thin compliant walls, has valves since it doesn't recoil
Anatomy of arteries and veins - -lumen: opening
-tunica externa: helps anchor the vessel to surrounding structures
-tunica media: external elastic membrane, smooth muscle, & internal elastic membrane
-tunica intima: sub-endothelial tissue & endothelium
Why is the cardiovascular system a closed circulatory system? - the fluid contents are
pumped from the heart throughout the body and back to the heart
What are some functions of the cardiovascular system? - -Transportation of gases,
nutrients waste
-prevents loss of blood from ruptured vessels
-helps fight off pathogens
What does the study of the cardiovascular system cover? - -muscular heart
-blood vessels
-blood
Where is the heart located? - Pericardial cavity within anterior portion of the mediastinum
What separates the thoracic cavity into 2 pleural cavities? - mediastinum
