Cardiovascular Physiology: How Fit is Your Heart?

Cardiac Output is the volume of blood in mL pumped per minute by each ventricle of the heart. You can find cardiac output by taking the amount of blood pumped from a ventricle in a single heartbeat (also known as stoke volume) times how many times the heart beats per minute (heart rate). With that being said, cardiac output is affected by exercise by making the heartbeat faster and pumping more blood out with every beat. Cardiac output is generally pretty consistent when the body is at rest though. These factors can then affect the blood pressure, just as any other activity or event that would speed up the heart. My group hypothesized that in general; cardiac output will increase while exercising. People who exercise 3 or more times a week will have a larger increase in cardiac output during exercise and also a quicker recovery rate than those who don’t work out at all. However, after performing the experiment and graphing the data we concluded that our original hypothesis was incorrect. We somehow confused ourselves and ended up predicting the opposite of what should/does actually happen. The correct hypothesis would’ve been, In general cardiac output will increase during exercise. People who don’t work out at all will have a higher cardiac output than those who workout on a regular basis (3-5x’s/wk). After seeing the results the second hypothesis makes so much more sense. People who workout on a regular basis will generally have a lower cardiac output because their cardiovascular health should be much better than those who don’t work out at all.

Radhika gandhi Atherosclerosis Paper

for Julie Stubrud’s PHA 1500 Anatomy and Physiology course Atherosclerosis is the hardening of the arteries. It occurs when fat, cholesterol, and other substances build up in the walls of arteries and form hard structures called plaques. Overtime, these plaques can block the arteries and cause problems throughout the body. This paper talks about the organ system that this disease affects is the cardiovascular system, What the function of the cardiovascular system is, how disease is contracted and…

Physiology Assigment Essay

Introduction Within this assignment the topics that will be covered include the cardiovascular system, the respiratory system, muscoskeletal system and also different energy systems. The ways in which exercise affects the body will also be studied and also the different ways to test exercise on the body. The study of physiology is defined as the study of the functions of living organisms and their parts. When relating physiology to sport and exercise this is basically looking at the different functions…

Essay On Stem Cell Therapy

advanced online edition of the journal Nature in a paper titled, "Human embryonic-stem cell derived cardiomyocytes regenerate non-human primate hearts." The findings suggest that the approach should be feasible in humans, the researchers said. "Before this study, it was not known if it is possible to produce sufficient numbers of these cells and successfully use them to remuscularize damaged hearts in a large animal whose heart size and physiology is similar to that of the human heart," said Dr…

Cardiovascular System

The components, of the cardiovascular system consist of the heart, blood vessels, and circulatory systems. Its main function is to pump blood around the body via blood vessels exchanging nutrients and waste by products between cells. In addition, they are also chief regulators in acidity, temperature, and extracellular fluid. It’s worth saying; cardiovascular system is a collection of systematic processes, meeting the body’s constant demands. Tissue requires oxygen on a continuous level, so when…

Arsenault, Email: upei.research@gmail.com, Tel: 902-218-3841 Description of the study We are interested in evaluating the effects of capsaicinoid ingestion (the active ingredient in hot peppers) on human metabolism and measures of cardiovascular physiology. There is evidence to suggest that capsaicinoid ingestion may alter fat metabolism and lead to changes in body composition and physical performance during exercise, through a shift in the use of fat as an energy supply. This study is…

Essay about Actions of Drugs

Actions of drugs on cardiovascular preparations Introducion The experiment outlined in this report was carried out with the intention to observe and explore the effects of certain named drugs on a vascular preparation, in the cardiac region specifically. The cardiovascular preparation used in this experiment was an isolation of the descending aorta of a rat. This isolate is particularly useful as it mirrors the responses that would be observed in a human sample, thus this experiment will give…

Baroreceptors

Trigger: You and your two friends work out a system to cheat on your physiology test. (DO NOT DO THIS. This is strictly a make believe story.) The genius friend says she will put one finger on your back for A and two for B. You feel one finger and mark down A and get the question wrong, however your friend feels two and answers correctly. You both were touched in the same location with the same intensity and duration. Why did you misinterpret the touch and your friend didn’t? Explain using a mechanistic…
