Blood Pressure

QuestionAnswer
What is the importance of blood pressure to the cardiovascular system? Blood pressure facilitates the constant flow of blood to all the tissues of the body
Define peripheral resistance The friction of blood against the vessel walls
What happens to blood flow when the pressure increases? When pressure increases, flow increases
What happens to blood flow when resistance increases? When resistance increases, blood flow decreases. To overcome this resistance the heart must generate enough pressure.
Describe the function of valves in medium-sized veins BP is so low in venules and medium-sized veins that the blood cannot overcome the force of gravity. Valves prevent the back flow of blood and any body movement that compresses a vein will push blood back towards the heart, improving venous return.
List the three mechanisms that allow blood to get back to the heart Valves, Muscular Compression and Respiratory Pump
Describe Cardiac Output The CO can be calculated by multiplying the average stroke value by the HeartRate and is controlled by the nervous and endocrine systems. CO=HR
Complete the equation BP= Blood Pressure = Cardiac Output x Peripheral Resistance
Describe Muscular Compression contractions of skeletal muscle near a vein compress it and help blood to return to the heart
What are the three variable factors that influence tissue blood flow? Cardiac Output, Peripheral Resistance and Blood Pressure
