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

Report The Effects of Exercise on the Cardiovascular System Introduction Exercise has a major impact on the cardiovascular system and its efficiency in the human body. There are many concepts which need to be examined to understand exercise and the cardiovascular system‚ such as systolic and diastolic blood pressure‚ cardiac output‚ total peripheral resistance‚ and physiological pathways. According to the European Journal of Cardiovascular Prevention and Rehabilitation‚ exercise provides a change
