Activity 4.3: The Heart As A Pump

4. Remelt the contents of the tube and add the counterpart component based on the given schedule. Ask the demonstrator to adjust the cooling water between mixtures. During the experiment, record and plot the data obtained for all mixtures listed. The experiments are stopped as follows:

The project that I chose to research was the effect of Ibuprofen on the heart

   •Hypothesis: If different sized beakers (100 ml, 50 ml, 250 ml, 400 ml) are placed over

The process that we will use for the water in the cylinder is we will fill a 100 ml mark and pour the contents in a dry 100ml flask about twice and we will find the percent difference. And to find the percent difference we will have to use the equation right here. For the Cube we will weigh six stoppers but once at a time and compare the results so that we could find the average of all six cubes.

If they didn’t recover before this experiment, their previous experiment would have affected their heart rate.

The heart plays a vital role in the human body and works tirelessly for humans. There are many people who have misconceptions on the heart, don’t know why the heart is one of the important organs, or how it works. The Greek philosopher Aristotle recognized the heart as one of the most important organs of the body, the first to form according to his observations of chick embryos in the fourth century B. C. During the Renaissance revival of anatomy, it assembled the possibility of physicians to know the basic structure of the heart. By the end of the seventeenth century, the anatomy of the heart was accurate and due to an English physician called Harvey who examined meticulously the function of all of the heart’s different parts and came to a

The cardiovascular is a very imperative system within the body. The cardiovascular system is made up of and contains organs such as the heart which plays an important role within the human body. It also contains blood vessel; veins, capillaries and arteries. All of these have their own functions within the body so they differ. The heart organ is in control of getting blood around the body, it does this by pumping it which then goes through the different blood vessels linked to the heart to the rest of the body. The veins have the job of transporting blood back to the muscular organ (heart) whereas arteries do the opposite as they move blood away to the heart and transport it to the whole of the body.

An improvement to the experiment could be doing the trials for a longer amount of time until it reached the resting heart rate, using a heart rate monitor or manual pulse reading for the whole experiment instead of alternating between

The heart is a very complex and complicated structure. It has many different functions and is vital to human life. The heart also supplies the body with oxygen and other nutrients and other numerous things. There are many different parts in the heart contributing to the endless cycle.

- Pericardium: The outer protective covering is a sac of fibrous tissue. It is continuous with the

All materials were obtained to start the experiment. To measure the heart rate after one minute of exposure, 44

The purpose of the experiment is to see how different variables affect pulse rate and blood pressure.

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

In the osmosis and diffusion portion of the lab a 6 inch dialysis tubing was tied off on one end, filled with 20mL of potato starch, and then tied off at the other end. Then a 500mL beaker was filled with 300mL of water and 50

Epicardial Adipose Tissue is a layer of fat surrounding the heart. In this project, I will conduct an experiment how obesity affects the transportation of blood and nutrients to the heart in patients. I will construct two type of hearts, one that is a normal healthy heart where fluids are pumped regularly and the transition between blood and oxygen is exchanged easily, then I will construct a fatty heart where the arteries are clogged and transportation of material is complexed.
