Pulse, Blood Vessels and Disorders of Cardiovascular System
Class Summary - Today we started talking about pulse. We defined pulse and talked about the 7 major pulse points. We used stethoscopes to try to hear our heart beat at those seven points. Today we finished off talking about pulse. We talked about resting heart rate. We took our resting heart rate and compared it to the norm. We talked about maximum heart rate and that the universally accepted formula for maximum heart rate is 220-age. Then we talked about target heart rate which is the range in which we want to work out to get benefits. This is 60-80% of the maximum heart rate. We talked about blood vessels. Arteries take blood away from the heart and to the body. Veins return used blood to the heart. Arterioles connect arteries to the capillaries. Capillaries are where blood exchange waste and nutrients into the body. Venuoles connect capillaries to veins. Then we discussed some common diseases / problems with the cardiovascular system.
Homework - Test on Tuesday
Objectives - Students will define pulse and tell where the pulse may be taken. Students will name the three types of blood vessels and describe their structure and function. Students will describe the anatomical and physiological changes that occur in the cardiovascular system as we age.
