Blood Pressure Lab
1. State a problem about the relationship of age and gender to blood pressure.
At younger ages, both males and females have about the same problems where weight and family history have a higher effect on their blood pressure. As they age, the problems with blood pressure increase drastically with being over weight, consuming alcohol, and having a lot of salt in their diets.
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.
As people age, their blood pressure would get worse due to bad diets, plaque build up on the heart, and large amounts of salt.
3. How will you use the investigation screen to test your hypothesis? What steps will you follow? What data will you record?
Each age group changes the amount of blood pressure problems, and it would be important to record what different factors show up more often then others. I would record data like different family history or personal diets.
4. Analyze the result of your experiment. Explain any patterns you observed.
As the men and women age, their blood pressure does show more problems all around. There was only one man who seemed to be health but still had dangerously high blood pressure. There were similarities between the men and women on the fact that there was fairly equal amounts of people drinking and overweight that had blood pressure issues.
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, because there was a change in blood pressure as they age and it appeared to be due to bad diets and lack of exercise.
6.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?
The people who were out of range were usually part of a group with lack of exercise and bad diets.
7. List risk factors associated with the hypertension. Based on your observation, which risk factor do you think is most closely associated with hypertension?
I think the biggest correlation with hypertension is being overweight and having a lack of exercise in their daily life.
8. 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?
As I have been saying, I do believe being obese could have a strong correlation with high blood pressure. Other factors that can effect in combination could be high salt diets and alcohol consumption.

Compendium Review
Chapter 5The cardiovascular system is the heart and blood vessels, The heart is what pumps the blood through the body and the vessels are what enclose the blood.
There are different vessels like arteries or arterioles, capillaries and veins.
Lymphatic system is an assistant to the cardiovascular system, thye collect excess tissue fluids and return it to the cardiovascular system.
The heart is a cone shaped muscular organ between the lungs.
Pulse is the heartbeat rate, normal average heart rate is 12-20 beats per minute. B
Blood pressure is the blood being moved through the heart by the beat.
The pulmonary circuit is where blood travels to and from the lungs.
The systemic circuit is where the aorta divides into blood vessels that work for the body's cells and organs.
Lymph is the tissue fluid contained within the lymphatic system.
Chapter 6
91% of blood plasma is water
Blood transports carbon dioxide from the cell and brings hormones, nutrients and oxygen to the cells.
Blood maintains blood pressure and body temperature.
Blood is the fighter against infections.
Plasma proteins help with immunity and blood clotting.
Red blood cells do not have a nucleus
Red blood cells combine with oxygen and then transports it to the tissues.
White bloods cells have a nucleas and are clear.
White blood cells are either granular leukocytes or agranular leukocytes.
Granular leukocytes are eosinophils, basophils, and neutrophils.
Agranular leukocytes include momocytes and lyphocytes.
Platelets are from fragmentation of megakaryocytes in red bone marrow.
Platelets, prothrombin, and fibrinogen function in blood clotting.
ABO blood typing determines the presence or absence of type A antigen and type B antigen on the surface of red blood cells.
Homeostasis depends upon the cardiovascular system because it serves the needs of the cells.
The digestive system offers nutrients
the nervous and endocrine systems are involved in blood pressure.
Chapter 7
The lymphatic system consists of lymphatic vessels that return lymph to cardiovascular veins.
the thymus gland is where the T lymphocytes mature
Some secondary lymphatic organs are the spleen, lymph nodes, tonsils, and appendix
Immunity involves non specific and specific defenses and nonspecific includes the inflammatory reactions and protective proteins. Specific require B cells and lymphocytes and T cells and lymphocytes.
Active immunity can in induced by vaccines.
Passive immunity is needed when there in an immediate danger of infections or disease.
Cytokines are a form of passive immunity used to treat AIDS.
Allergic reactions come when our immune system responces to foreign substances in the body.
Chapter 8The first step in digestion is in the mouth, chewing your food. Next is the stomach and small intestine.
the stomach expands to store food and mixes the food with acid to help digest.
The small intestine receives bile that emulsifies fat and redies it for final digestion.
The enzyme that is produces by the pancreas is the finish process of chemical digestion.
The large intestin absorbs water, salts, and some vitamins and carries out defecation.
Carbs are necessary in the diet
Omega 3 fatty acids are protective agains cardiovascular disease.
Lab Unit 2
The ball that I used for my sit ups
My bedroom clock to take my pulse and respiratory rate
And my cousin's sphygmomanometer, she is a nurse and took my blood pressure each time :)

Unit 2 Lab Write Up
For our Unit 2 lab we were asked to measure our body’s metabolic rates like blood pressure, heart rate and respiration rate while at rest and after different activities. Our body’s need our different rates to stay at a good average to perform normally. Our heart rates need to vary from about 60 to 80 beats per minute at rest. Respiratory rates need to be at approximately 12 to 20 breaths per minute and resting blood pressure should be around 120/80. Although there are variations for these numbers in healthy people, they are an ideal approximation.
I think that my heart rate and respiratory rates will strongly increase with jumping jacks, sit ups and running a quarter mile. For my blood pressure I am not so sure how much it will change. I do understand that blood pressure itself is the blood flow into the arteries, I am not sure if it will jump drastically either way. I will guess it will also increase will all of the activities.

I think that my graphs and data were not too different then what I was originally expecting. It seemed that my Blood Pressure did the opposite of what I was thinking it would, but my heart rates and respiratory rates did increase like I thought they might because of the change in you body’s demands after exercise. I feel that there was a difference just because I was wrong on my assumption about my blood pressure because I didn’t seem to understand exactly how it changes with activities.
My conclusion to this lab is that the new understanding of heart rates, respiratory rates and blood pressure will change differently for each person and for me it allows a better understanding of what happens to my body during different exercises. Each of our different respiratory and cardiovascular organs work together to maintain a healthy pulse and breathing pattern and our heart needs blood forced through it to produce it’s beat. This shows that each of the parameters we tested correlate to the other.

A Day of Food
How healthy a daily diet do you think this is? Why?
- I think generally I could eat better. I don't feel I eat terribly, but I usually don't eat a good amount of veggies and fruits like I should. Also, I eat a lot of sodium in my diet and I think that it should be something I work on. I wasn't able to find any tab for water on this calculator but I tend to drink a large amount of water throughout my day too.
What would you change about this day's eating, if anything?
- I think it could have been better by eating more fruits and veggies and try to cut down on the sodium.
Do you find this kind of nutritional tracking helpful? Why or why not?
- I find it to be very helpful, especially because I had no idea I had so much sodium in my diet.
