Oxygen Circulation Immunity Lab

This lab was not difficult. It was not boring, either. It was however incredibly frustrating. I have no journal to show. I am glad I did take down all of the information, because it never emailed it to me. Needless to say, the professional element is lacking.

Here is the average blood pressures for each group:

Table

117	75	117	76
128	79	116	76
131	81	117	77
132	83	127	81
134	85	133	83

The x-axis shows the average systolic and diastolic pressure of first male then female for each age group. The y-axis shows the age groups starting from the youngest on top to the oldest on the bottom.


This is a graph displaying the information above.

Here is the journal (so to speak) with the questions and answers from the blood pressure investigations.




1.State a problem about the relationship of age and gender to blood pressure.

It seems the older one gets the more likely he/she is to have high blood pressure. This is slightly more likely in males than females.



2.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.

3.As the age of an individual in the study increases, so does their blood pressure. this is more likely in males than in females.


4.How will you use the investigation screen to test your hypothesis? What steps will you follow? What data will you record?

Take the average blood pressure of each age group in each gender. compare the average in each age group. record the number of people with hypertension in each age group. compare.


5.Analyze the result of your experiment. Explain any patterns you observed.

males have a steady increase of blood pressure as they get older. Females have a more drastic increase between the ages of 35 and 44. Male blood pressure is usually higher than female blood pressure. It is significantly higher than females in the 25-34 years of age range. perhaps this has more to do with the difference between female and male diet and alcohol consumption.



6.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?

The conclusion supported my hypothesis. The older a person gets the higher their blood pressure gets. The older a person gets the more likely they are to have hypertension.


7.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?

There were a few that were out of the normal range and higher than the average normal range. Those with higher blood pressure often either had high salt intake, were overweight, did not exercise and/or consumed alcohol.


8.List risk factors associated with the hypertension. Based on your observation, which risk factor do you think is most closely associated with hypertension?

I listed the risk factors previously. They include: lack of exercise, obesity, high-sodium diet, history of familiar hypertension and alcohol consumption. The highest risk factor is most likely a history of hypertension.



9.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 does affect blood pressure. It usually causes higher blood pressure. Obesity alone rarely causes hypertension. Lack of exercise, history of hypertension and high sodium diet are factors that would increase the risk of hypertension in obese individuals.
