The amount of resistance in a blood vessel is an important factor that can change the amount blood flow. One situation that can cause increased resistance is blood vessel diameter. Besides temporary vasoconstriction and vasodilation caused by the ANS, what organic molecule can increase resistance by sticking to vessel walls, resulting in narrowing the passageway for blood to flow?

low density lipoprotein

Consumption of fast food and processed foods can affect blood pressure. Excess _________ ions in foods causes the retention of water, which in turn increases the blood volume, resulting in increased blood pressure.

sodium
