Breakdown of the Problem

1. The question is asking about the effect of aldosterone on blood pressure.
2. We need to recall the function of aldosterone in the body and its role in the regulation of blood pressure.

Relevant Concepts

1. Aldosterone is a hormone produced by the adrenal glands.
2. It plays a crucial role in regulating blood pressure by controlling sodium and potassium levels in the body.
3. When aldosterone is secreted, it promotes sodium reabsorption in the kidneys. This reabsorption leads to water retention, which increases blood volume and, consequently, blood pressure.

Analysis and Detail

1. Sodium Reabsorption: Aldosterone acts on the distal convoluted tubules and collecting ducts in the kidneys, increasing sodium reabsorption into the bloodstream.
2. Water Retention: As sodium is reabsorbed, water follows via osmosis. This increase in blood volume from water retention raises blood pressure.
3. Impact on Blood Pressure: The overall effect of increased sodium and water retention due to aldosterone directly correlates to an increase in blood pressure.

Verify and Summarize

After analyzing the function and effects of aldosterone, we confirm that its secretion leads to an increase in blood pressure due to enhanced reabsorption of sodium and corresponding water retention.

Final Answer

The correct answer is increase. When aldosterone is secreted into the blood, blood pressure will increase.
