Clinical Correlations
100
The biggest artery in the body begins the systemic circulation
What is aorta
100
These are the major veins bringing blood to the heart
What are superior and inferior vena cava
100
This vein drains the upper thigh
What is femoral vein
100
This is where most of our blood is at any given time
What are veins
100
This is the clinical term for gnarled, enlarged veins
What are varicose veins
200
This refers to an increase in the diameter of arterioles
What is vasodilation
200
These are the smallest vessels, only one cell wide
What are capillaries
200
This large artery continues downward through the thorax and abdomen
What is the aorta
200
These are the two quantities that go into the equation for blood flow
What are pressure and resistance
200
This is a condition in the arteries that can lead to high blood pressure
What is atherosclerosis
300
This is the only artery that carries deoxygenated blood
What is the pulmonary artery
300
These are found in veins and help prevent back-flow of blood
What are valves
300
This artery supplies the top of the foot
What is the dorsalis pedis artery
300
Blood volume is a determinant of this blood flow-related quantity
What is blood pressure
300
The parts of the veins that are damaged in "spider veins":
What are valves
400
This helps maintain blood pressure and push blood through arteries
What is smooth muscle
400
Two things exchanged through capillary walls
What are gases and nutrients
400
This artery splits into two branches that supply the head
What is the common carotid artery
400
This quantity is inversely related to vascular resistance
What is vessel radius
400
These are the largest contributor to plaques in atherosclerosis
What are white blood cells
500
Smooth muscle is arranged in this way in arterioles
What are circular rings
500
This helps bring blood back by compressing veins
What is skeletal muscle
500
The veins runs with an artery that comes from the axillary artery
What is the brachial vein
500
These vessels, as a whole, have the highest resistance
What are arterioles
500
This is defined as a systolic BP between 120-139 or a diastolic BP between 80-89
What is pre-hypertension
