Lab 4: Blood Pressure

Name: Stephen Fletcher

Journal Questions

Directions: Answer the following questions about your lab. Submit via Assignments in the Course Tools menu.

1. State a problem about the relationship of age and gender to blood pressure.
Blood pressure tends to increase with age and males are generally more susceptible to having high blood pressure.

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.
The average blood pressure of the group would increase, as the age group increases in years. Also, the male subjects will have earlier onset high blood pressure.

3. How will you use the investigation screen to test your hypothesis? What steps will you follow? What data will you record?
I will look at the subjects with hypertension and see what patterns I can find among the patients. I will record the similarities of risk factors.

4. Analyze the result of your experiment. Explain any patterns you observed.
The experiment showed that age and body weight contribute greatly to the blood pressure of an individual. Persons that were obese and in an older age demographic had greater instances of hypertension. Hypertension occurred earlier in males than in females. Hypertension seemed to be greater influenced by behavior/lifestyle choices than family history.

5. 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. Blood pressure tends to increase with age and males are generally more susceptible to having high blood pressure.

6. During the course of your experiment, did you obtain any blood pressure readings that were outside of the normal range for the group being tested? What did you notice on the medical charts for these

From the diagram, you could see the difference between normal heart and a hypertensive heart.…

    Hypertension is the medical term for high blood pressure. A normal blood pressure is 120/80. A blood pressure reading higher or equal to 140/90 is considered abnormally high. Elevated blood pressure means your heart is working harder than normal, putting both your heart and arteries under great strain. High blood pressure is serious business. On average, people with uncontrolled hypertension are:<br><li>Seven times more likely to have a stroke. <br><li>Six times more likely to develop congestive heart failure. <br><li>Three times more likely to have a heart attack.<br><li>Different types of hypertension<br><br>From my research, I didn't find any other types of hypertension.<br><br><b>What are some causes?</b><br>In 90% of cases, the cause of hypertension is unknown. This is called "essential hypertension". The other 10% of cases is called "secondary hypertension". Secondary hypertension is caused by kidney disease, severe narrowing of the aorta, tumors in the adrenal gland, or hardening of the arteries. There are many factors associated with high blood pressure, including smoking, age, race, a high-salt diet, excessive alcohol consumption, stress, use of birth control pills, obesity, and a sedentary lifestyle.<br><br><b>what age is at risk?</b><br>If you are a man from 35 to 50, you are in a high-risk zone for hypertension, this is especially true if hypertension also runs in your family. It is less likely for women to have high-blood pressure, but the risk increases after menopause.<br><br><b>Symptoms</b><br>There are usually no symptoms for hypertension. This is why it is often called the "silent killer". Actually, you could have hypertension for years and not know about because you feel fine. But symptoms do show up if the case is severe. Some of these symptoms are:<br><li>Headache <br><li>Nosebleeds <br><li>Drowsiness <br><li>Confusion <br><li>Dizziness <br><li>Irregular heartbeat <br><li>Numbness and tingling in hands and feet <br><li>Coughing up blood…

    Chronic disease The prevalence of hypertension increases with age and is higher in African American than in Whites. In comparison to whites, African Americans developed high BP at an earlier age, and it is more severe at any decade. As a result, African Americans have a higher prevalence of stroke, heart disease, and end-stage renal disease when compared with whites. In addition, African American has a higher mortality rate at every level of BP elevation compared with whites. In both rises, the prevalence is higher in less educated than in more educated people. Hypertension is more prevalent in men than in women until age, 55 after age 55 it is more prevalent in women than men. The status of hypertension control has improved considerably over the past years. Large-scale education programs provided by various organizations have increased awareness of hypertension. The percentage of patients with hypertension on medication who have their BP controlled has also improved substantially. The diagnosis of hypertension requires that elevated readings be present on at least three occasions during several weeks.…
