Solution

failed
failed

The answer is b.) Both cardiac output and blood pressure will decrease.

Explanation:

  1. Cardiac Output: The cardioaccelerator nerve is part of the sympathetic nervous system, which helps increase heart rate and contractility, thereby increasing cardiac output. If this nerve is damaged, the heart's ability to increase its rate and strength of contraction in response to standing up rapidly is impaired. This would lead to a decrease in cardiac output because the heart cannot compensate for the sudden pooling of blood in the lower extremities.

  2. Blood Pressure: When a person stands up quickly, blood tends to pool in the lower body due to gravity, which can lead to a temporary drop in blood pressure. Normally, the body compensates for this by increasing heart rate and constricting blood vessels, actions mediated by the sympathetic nervous system. However, with the cardioaccelerator nerve damaged, the heart's response is blunted, and the compensatory mechanisms are less effective, leading to a decrease in blood pressure.

Therefore, upon standing rapidly, both cardiac output and blood pressure are likely to decrease due to the impaired sympathetic response caused by the damage to the cardioaccelerator nerve.

When the United States Steel Corporation was created in 1902, it was the largest corporation America had known up to that time. It produced twice as much steel as all of its domestic competitors put together. Today, the United States Steel Corporation produces about 20 percent of the steel that is made in this country. In 1902, the United States Steel Corporation produced not less than 66 percent of the total domestic output of steel.
