Cardiovascular Dynamics

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 ...

Effects Of Exercise On Cardiovascular Function

Effects of Exercise on Cardiovascular Function Fierra Harris Saginaw Valley State University Cardiovascular disease (CVD) is the leading cause of death worldwide that affects the heart and the surrounding vasculature (Mathers et al. 2009). CVD can be brought on by behavioral or inherited characteristics such as obesity, diabetes mellitus, hypertension, family history, and a sedentary lifestyle (World Health Organization, 2013). These conditions and thus cardiovascular disease are prevalent...
