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

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

of water in the fluid that line the walls of the alveoli. Activity 5: Effect of Thoracic Cavity Puncture 1. What happened to the left lung when you clicked on the valve button? It deflated. 2. Why? Because the pressure in the left lung was 0 and the right lung changed rapidly‚ the air moved into the intrapleural space through the opening‚ causing intrapleural pressure. 3. What has happened to the “Total Flow” rate? It was reduced by ½. 4.

During ‘Infancy’‚ which lasts from birth to eighteen months‚ babies change from a helpless newborn‚ to a child who can lift up their own head at three months‚ sit up unsupported at six months‚ walk at sixteen months and kick and throw a ball at two years old. Newborn babies actually lose some of their birth weight to begin with
