Answer:
D. Decreasing vessel diameter
Explanation:
Cardiac output is the amount of blood pumped per unit time by heart. Increased cardiac output corresponds to increased blood pressure which will result in increased blood flow. In vasodilation the smooth muscles within the blood vessels relax making them wide hence decreasing vascular resistance leading to more blood flow. Decreased blood viscosity will also decrease the resistance to blood flow.
Decreasing vessel diameter will not increase the blood flow, it will rather restrict it because there will be more resistance to passage of blood due to small space.

Chromium may play a role in decreasing the risk of developing diabetes and insulin resistance. It can lower the level of glucose and improve insulin sensitivity .
Chromium deficiency may increase blood sugar , cholesterol level, increase the risk for a number of conditions and triglycerides.Fatty acids and cholesterol synthesis stimulates chromium which important for brain function and other body processes.
Chromium helps in keep blood sugar levels normal by improving the way the body uses insulin. If the level of chromium is high in the body then stomach problem and low blood sugar and can damage the liver, kidney and nerves.
