The Role Of The Circulatory Systems And Defense Systems

Introduction: In this experiment, cardiovascular fitness is being determined by measuring how long it takes for the test subjects' to return to their resting heart rate. Cardiovascular fitness is the ability to "transport and use oxygen while exercising" (Dale 2015). Cardiovascular fitness utilizes the "heart, lungs, muscles, and blood working together" while exercising (Dale 2015). It is also how well your body can last during moderate to high intensity cardio for long periods of time (Waehner 2016). The hypothesis is that people who exercise for three or more days will return to their resting heart rate much faster than people who only exercise for less than three days.

system where the heart is the pump, which pumps the blood, and the blood vessels are

We conducted a study, 2 subjects took their blood pressure and pulse before exercise, immediately after exercise and 5 minutes after exercise, their appearance and sweating was also noted. This table shows that before exercise both subjects had relatively normal blood pressure, immediately after exercise both subject 's blood pressure had dropped. The blood pressure was retested after 5 minutes of rest both subject 's blood pressure risen back up to a normal level. Before exercise subject A 's pulse was average, after exercise it had risen to compensate for the need of oxygen to get around the body quicker. After 5 minutes this had then returned back to a normal pace when the body had relaxed. Subject B had an average pulse before exercise, immediately after exercise it had risen, 5 minutes after exercise it had dropped again to a normal pace. the differences in pulse shows that subject A is healthier than subject B because the difference between subject A 's resting and exercise

I am the Bob the heart. I am located just behind and slightly left of the breastbone. The system that works with me is the circulatory system. The circulatory system is an organ system that permits blood to circulate and transports nutrients, oxygen, carbon dioxide, hormones and blood cells. The circulatory system also helps forming cells in the body to nourish it and help fight diseases.

Our cardiovascular system is composed of the heart and blood vessels. The main purpose of this system is to transport substances throughout the body. Even though transportation is the main function of the cardiovascular system, it is not the only function. Along with transportation we have protection and regulation.

In this assignment I will be introducing a formal report that is based on an investigation into how the body responds to exercise and which analyses the results from the investigation. The investigation involves myself and other pupils in my class. I will be doing the Harvard step test. the other pupils in my class will be monitoring my heart rate, breathing rate and temperature before and after the test.

1.The fluid surrounding tissue cells is called? interstitial fluid.2.What are the functions performed by the circulatory system?-The circulatory system supplies oxygen and nutrients to our body by working with the respiratory system.- It also helps carry waste and carbon dioxide out of the body3.What is the fluid type that holds many of the human body fluids? Intracellular fluid4. Name fluids that are nearly identical in content except for proteins. Plasma and interstitial fluids.5.What function of blood is most critical to life on a second to second basis? Blood Regulation6.What fluid has the highest concentration of proteins? Intracellular fluids7.What is the most prevalent positive ion in interstitial fluids? Sodium8.What is the principal

In addition, heart rates vary according to exercise, physical needs, age, gender, air temperature, etc. In this experiment the dependent variable

Chapter twenty is the last one of the circulatory system and it discussed about the blood vessels and circulation. Blood vessels is the distribution network or the network of tubes. There are three main blood vessels in the heart there are artery, veins and lymphatic. The arteries are all the blood vessels that take blood out from the heart. It tends to be thick, strong and tough because all the blood is rushing through the arteries. The arterioles are like the mini arteries that branch off of the arteries. Capillaries are the smallest blood vessels that comes off from the arteries and physically takes blood, oxygen and nutrients inside the blood to the cells that need it. It connects the arteries and vein and the it main function is to exchange

Research Question: What is the effect of practicing aerobic sports on a daily basis, on the recovery heart rate of people?

The effects of exercise on blood pressure, heart rate, respiration rate and electrical activity of the heart were assessed. The measurements of respiration rate, pulse rate and blood pressures were noted as described in Harris-Haller (2016). Data was first taken from subjects in a relaxed position and then followed by sets of reading after exercising based on one minute intervals. The data also noted sitting ECG traces from Harris-Haller (2016). The respiratory rate, pulse, blood pressure, P wave, QRS complex and T wave were defined for each subject. The class average was calculated for males and females and graphed to illustrate the results by gender for each cardiopulmonary factor.

veins to the tissues of the body. These walls do not let out blood but

The literature on the effects of exercise of cardiac output maintains the idea that exercise should affect cardiac output- pulse rate, systolic blood pressure, diastolic blood pressure, QRS-pulse lag, P-T and T-P intervals, because of increased heart rate. For our experiment, we tested this theory by measuring our cardiac output before and after some rigorous exercise. We measured the individual cardiac output and then combined the data to compose a class-wide data average. We compared the results of the experiment to what we expected, which was that exercise does affect our heart. Our data from this experiment supported the notion that exercise does, in fact, change cardiac output.

The purpose of these lab exercises is to understand the function and importance of an electrocardiogram. This lab will demonstrate how stress levels or different elevations can affect human heart rate. Furthermore, the equipment used in the experiment will show the functions in the right and left arm; as well as, in the right and left ankles. Finally, the lab will serve a purpose as a way to know how to read an electrocardiogram and calculate the heart rate.

Carry out an experiment to measure the heart rate and ventilation rate before, during and after moderate exercise.
