The Parts of the Cardiovascular system (Lab Report Sample)
Module 3: Lab Exercise
An Examination of the Heart: From the Micro to the Macro Level - Using a Sheep's Heart
This is a Hands-On Labs exercise that explores the heart. Here you will view the cells in the heart, veins, and arteries at low, medium, and high magnification. You will trace the flow of blood through the heart. You will also complete a full dissection of a sheep heart (I will do this part at home and send it to you!).
Complete all three exercises in the Hands-On Labs experiment about the cardiovascular system by labeling images and filling in tables. ***You do not need to submit the Lab Report Assistant.***
Create a Report:
Use the following outline to describe the data from your lab in a report or presentation. Label each portion of the lab as described below.
Start with a broad discussion of the heart. Why is this topic of interest to you? What will you learn? Conclude the introduction with a statement about specific items the lab is exploring. What are you comparing and what are some differences you expect to see?
Identify all items that you used and the exact quantities, as applicable.
Describe how you conducted the experiment, including any safety precautions you took while performing the lab. Be sure to include any changes that you made to the original instructions. This should be a short, paraphrased version of the methods from the lab. Do not copy from the lab; Turnitin will highlight it as plagiarism.
Insert all images and tables from the lab here, including a brief statement about each one.
Review what you observed. What differences did you notice as you explored the magnified tissues? How are veins and arteries different? What are some things you noticed about the sheep heart? Are there differences between the right and left sides? Why might this be? What other differences or interesting characteristics did you notice while performing this lab?
End with a section describing what was particularly interesting to you; identify errors that may have impacted your results or note errors in the lab itself; and provide recommendations for future labs.
1) If you are doing the report, it should be 4-5 pages long, not including the title page.
2) Reference at least two journal articles.
3) Include a title page and a reference page at the end.
4) Follow the CSU-Global Guide to Writing and APA.
Lab Exercise – Parts of the Cardiovascular system
Your Institution of Affiliation
The Circulatory system or the Cardiovascular system consists of three essential parts, which are (1) the heart, (2) the blood vessels, and (3) the blood. While this system is relatively simpler in structure than what was previously discussed (i.e. endocrine system) it has one of the most significant function as it delivers oxygen, food, water, wasted, hormones and other essential nutrients throughout the whole body. In other words, without this system, the functions of any organs (and systems as a whole) would cease to exist. In terms of its structure, the heart (“double pump”) serves as the central component that continuously keeps the flow of the blood and all other particles suspended on it within the body. This organ is mainly located in the body's medial region, with a slight inclination to the left making two-thirds of its structure leaning slightly to the left side of the body. Connected to the heart are major arteries (e.g. aorta and pulmonary artery) and veins (e.g. superior and inferior vena cava) that move the blood away and towards the heart, respectively. There are also tiny vessels (called capillaries) that serve as points of exchange between oxygenated and deoxygenated blood that is usually found within the interstitial space and the lungs. Lastly, the blood that is being circulated throughout the whole body is composed of three types of cells and one non-cellular fluid, these are (1) White Blood cells (leukocytes), Red Blood cells (erythrocytes), (3) platelets, and (4) plasma. In line with this, it could be seen the interesting dynamics between these structures together with its utmost importance for life, purports the need for a closer inspection of the heart. Thus, in this lab experiment, the researchers conducted a dissection of the heart as well as major veins and arteries which are adjacent to it. Specifically, the structures, functions and the other operating mechanisms (e.g. blood flow and blood pressure) were examined in further detail and compared to one another. In order to further this understanding, the latter sections of this study would also focus on the microscopic structures of the cardiac muscle. All in all, the researcher believes that by examining the structures of the cardiovascular system with both macro and micro perspectives, a better understanding, and appreciation of its functions as well as provide an overview of possible risks (i.e. heart diseases).
This experiment would require materials to be brought by the researchers as well as those which are readily provided by the instructors. Both of the following lists of materials are enumerated below.
