Sheep Heart Dissection Lab

728 Words3 Pages

The purpose of the Sheep Heart Dissection lab was to take a look at the heart's anatomy and all the parts that it consists of. This lab helped us learn how the heart is able to function, and gave us a hands on look at what a real heart looks and feels like. I worked on this lab with Jose, and Alex. We completed the procedure in one day of class, and had the questions completed by the second. Methods We participated in this lab by carefully following a procedure. The first procedure was to locate and identify different veins and arteries stemming off the heart. We labeled the pictures in the packet according to what we saw. We were then instructed to make an incision along the length of the heart. We continued to open the heart up and inspect the inside. We were able to see all the valves and chambers inside the heart. We used a probe to check out the different valves inside to see the vein or artery they belonged to. Results/Data …show more content…

I had a lot of insights when I participated in this lab. The feel of the heart was solid with only a little give. It reminded me a lot of the tennis ball we had to squeeze during the heart stations. We also used a dull probe to feel down the aorta and I was shocked at how far the probe when down. The biggest realization was when we looked inside the heart. I was amazed by the chordae tendineae, or ¨heart strings¨. They really looked like bunch of strings inside the right ventricle. The questions included the measurements of the heart and a lot of labeling on the anatomy of the heart. I noticed that the labeling was tougher than I thought it would be. Our heart was the from the same animal but they looked very different to me when we compared the picture to our heart. The questions about what hold the valves together and which artery or veins go along to which chamber helped me further my understanding of the heart’s

    The Pintails heart is like a mammals consisting of four chambers, two ventricles and two atria. The left ventricle pumps blood to all major organs in the body and throughout the rest, only excluding the lungs. This causes the left ventricle to be larger and more muscular. The lungs are fed blood from the right ventricle, which is the only the only function of that ventricle. The oxygenated blood coming from the lungs is fully separated from the oxygenated blood coming from other parts of the body.

    The data that my group collected refutes our hypothesis because the difference and inconsistency of the breaths per minute in the ventilation rate and the breath volume in liters are all around the same amount. The p-value from the t-test for ventilation (breaths/minute) was 0.27, and for the breath volume (liters) it was 0.15. Both p-values are above 0.05, the Null Hypothesis is accepted. There is an overlap of data. The answer to the previous question is yes, mild and vigorous exercise affects the ventilation rate the same way as breath volume rates with little to no difference.

    I am competent in diagnostic tests such as exercise tolerance testing and Technetium stress tests, with the ability to prep the patient for the procedure, analyse the results and produce reports for consultants. I am able to work independently on analysing ambulatory monitoring devices such as a 24 hour Holter, searching for abnormalities on the ECG recording that may explain patients’ symptoms and produce written reports to assist doctors with diagnosis. Working in the cardiac catheter laboratories to assist with invasive diagnostic tests such as coronary angiography and percutaneous coronary intervention has enabled me to develop my knowledge on structural and functional abnormalities affecting the heart and coronary arteries. I have been able to develop my team working skills as the catheter labs are composed of a multi-disciplinary team consisting of cardiology consultants, registrars, nurses, radiographers and cardiac physiologists. Effective communication plays a key role in providing competent patient care and ensuring Trust standards are met.

  • Animal Testing Benefits

    1822 Words  | 8 Pages

    Even though many life threatening diseases were being cured and the field of medicine was quickly expanding, society continued to debate the issue of animal testing. It is presumed that society does not fully understand how many human lives have been augmented by the use of animal testing. In 1968 Alain Carpentier, a French cardiologist, experimented on the hearts of pigs (Pro Con). His experimentation led him to pioneer a way of not only repairing faulty hearts, but he also mastered the art of replacing those that are not in good enough shape to simply repair (EPO).

    Abstract Animal testing the experiments performed on animals that are used to test the effectiveness and safety of a wide range of things, from medication to cosmetics. They are also used to understand how the human body works. Animal testing is one of the major controversial issues, but animal testing has dramatically contributed to science. First, some people think that animal testing should not be used for testing medical techniques and drugs. However, medical research involving animal testing improved the health of human beings.

  • Essay On Atherosclerosis

    One of the most widely used tests for atherosclerosis is a cardiac angiography. This is done by doing a catheterization procedure and utilizing x-rays to look at the blood vessels as a liquid dye is injected into the blood vessels. This can determine where the blockage is and if the treatment should be a CABG surgery or a PCI surgery. The last and most detailed test is the intravascular ultrasonography. This test also uses catheters and allows for images of the arteries to be

Every experimental group contained saline or isoproterenol and was inserted below the skin and back. Gene expression levels were also measured at 3 and 14 days after the infusion for the cardiomyocyte injury. During the echocardiography, the measurements needed were traced by the levels of the papillary muscles.

  • Tomography Scan Essay

    951 Words  | 4 Pages

    A computerized tomography scan, also known as a CT scan, is a series of x-ray images taken from different angles, specifically referencing the coronary area. It uses computer processing to detect calcium deposits found in atherosclerotic plaque in the coronary arteries of heart disease patients. It generates three-dimensional snapshots of the blood vessels that surround the heart, as well as the heart itself (Levy, 2014). When CT scans were first invented by the British engineer, Godfrey Hounsfield, in 1972, the procedure was not effective on the cardiovascular system, as the heart is always in motion. In the early stages of the CT scan, it was only able to take 1-8 slices per minute, which is much slower than the rate of the heart.

  • Physical Assessment In Advanced Practice Nursing

    During the exam, the advanced practice nurse would begin the physical assessment based on observation. The clinician would be looking for signs of growth failure, peripheral perfusion issues, or cyanosis (Etoom & Ratnapalan, 2014). The next steps of physical assessment would include vital signs, assessing the peripheral and central pulses, precordium exam, palpation, and auscultation (Etoom & Ratnapalan, 2014). The apex as noted in the case scenario is at the fourth intercostal space in the midclavicular line and is felt during the first heart sounds (Etoom & Ratnapalan, 2014). The clinician would auscultate the heart sounds in the mitral, tricuspid, pulmonary, and aortic areas of the heart by listening systemically for normal sounds (Etoom
