The heart receives its own blood supply from the coronary artery. This artery can sometimes be blocked by a buildup of plaque. The cross sectional stages of a progressively blocked coronary artery are illustrated below.
Which of these is a disadvantage resulting from the progression of plaque in the coronary artery?
Blood pressure is stable only during periods of exercise.
The amount of water retained in the vascular system is increased,causing a dilution of blood volume.
Blood pressure is increased, resulting in the inability to move blood to locations that need nutrients and oxygen.
Plaque buildup makes the heart rate decrease, causing nutrients to be absorbed by organs that are closer to the heart.
- 7. Multiple Choice
The phrase "don't go swimming after you eat a full meal" is based on which of the following biological principals?
Swallowing water can dillute the oxygen concentration in your blood stream.
Swimming with a full stomach increases blood pressure which could lead to a heart attack.
Blood flow during exercise is diverted away from organs making it hard to digest the meal.
When swimming, the increased water pressure on the body narrows blood vessels making it difficult to digest food.
