Questions to Accompany Physio-Ex: Cardiovascular Dynamics 1. Describe the relationship between blood pressure and blood flow. Blood flow is the amount of blood flowing through a vessel‚ tissue‚ or organ during a given period of time and Blood pressure is the force exerted on a vessel wall by the blood traveling through it. 2. Describe the relationship between blood viscosity and blood flow. As blood viscosity increases‚ blood flow decreases. 3. Describe the relationship between vessel

Nancy Yedanapalli physio ex Activity 6 1. Explain why the larger waves seen on the oscilloscope represent ventricular contraction. a. The ventricular contraction is of greater force than the atrial contraction‚ since the ventricular contraction functions to send blood throughout the entire body (systemic circulation)‚ where as the contraction of the atrium send blood only to the lungs and rest of the the heart (pulmonary circulation). 2. Explain why the amplitude

Cardiovascular Dynamics Vessel Resistance Key Terms: 1. Blood flow- the amount of blood moving through a body area or the entire cardiovascular system in a given amount of time. 2. Pheriphial resistance- the opposition to blood flow resulting from the friction developed as blood streams through blood vessels. 3. Viscosity- A measure of the “thickness” of the blood and is caused by the presence of proteins and formed elements in the plasma 4. Systole 5. Diastole 6. End diastolic volume
