Detailed explanation-1: -Which of the following factors would most directly affect blood flow through the circulatory system? The factors that most directly affect blood flow are blood pressure, blood volume, resistance and activity level.

Detailed explanation-2: -You need to know the factors that affect blood flow through the cardiovascular system: blood pressure, blood volume, resistance, disease and exercise. You need to know how these factors affect blood flow.

Detailed explanation-3: -Smoking, obesity, diabetes, and older age are some of the risk factors for poor circulation, but genetic conditions, infections, and lifestyle habits can contribute. If you notice tingling, pain, or other signs that could indicate circulatory problems, seek medical advice.

Detailed explanation-4: -The three factors that govern local blood flow are pressure, the resistance to flow, and blood viscosity. Pressure: The pressure in a vessel is caused by the force of blood pushing against its walls. This force can be increased or decreased depending on the vessel’s diameter, length, and wall thickness.
