Learning Objectives
- Define and contrast blood flow and blood velocity, and explain how blood flow and velocity are controlled
- Define blood pressure, and explain how blood pressure is controlled on both local and whole body levels
- Differentiate between systolic blood pressure, diastolic blood pressure, mean arterial pressure, and pulse pressure, and their control
- Describe and explain the relationship between blood flow, pressure and resistance
- Explain Poiseuille’s Law of blood flow
- what is blood flow (F)?
- what is blood velocity?
- what are the 2 main determinants of blood flow?
- blood flow vs velocity throughout the circulatory system?
- does Doppler ultrasonography measure flow or velocity?
Blood Pressure

- what are the determinants of BP?
- what is systolic (SBP) vs diastolic (DBP) pressure? values?
- what is pulse pressure (PP)? value?
- what is mean arterial pressure (MAP)?
- what factors regulate MAP?
