Unit 2, Lab 1





State a problem about the relationship of age and gender to blood pressure.
The problem that relates to age and gender has several variables to account for. Those would be weight issues for ped's. Younger people have weight factors that account for an elevated B/P. The older one gets, the weight, hx of hypertension, and lack of exercise play a larger role. With females, weight and high salt intake play a large roll.
Use your knowledge about the heart and the circulatory system to make a hypothesis about how the average blood pressure for a group of people would be affected by manipulating the age and gender of the group members.
The younger you are the heart doesn't have to work as hard due to a smaller container. When you get older, hx, poor diet, lack of exercise cause your body to work harder to circulate blood, which in turn raises your B/P.
How will you use the investigation screen to test your hypothesis? What steps will you follow? What data will you record?
Collect a baseline, look at risk factors, and height to weight ratio will give me the evidence I need to understand what factors cause a change in B/P.
Analyze the result of your experiment. Explain any patterns you observed.
I saw that weight, lack of exercise, and hx of hypertension play a huge role in b/b.
Did the result of your experiment support your hypothesis? Why or why not? Based on your experiment what conclusion can you draw about the relationship of age and gender to group blood pressure averages?
Yes, Females have weight and hx of hypertension affect the pump greatly. Males have hypertension issues related to lack of exercise and hx of hypertension.
During the course of your experiment, did you obtain any blood pressure reading that were outside of the normal range for the group being tested? What did you notice on the medical charts for these individuals that might explain their high reading?
Yes, I saw a weight and hx of hypertension as the common factor
List risk factors associated with the hypertension. Based on your observation, which risk factor do you think is most closely associated with hypertension?
Hx of hypertension
What effect might obesity have on blood pressure? Does obesity alone cause a person to be at risk for high blood pressure? What other factors, in combination with obesity, might increase a person's risk for high blood pressure?
Obesity and high salt diet with lack of exercise.
