Lab Report Assistant
This document is not meant to be a substitute for a formal laboratory report. The Lab Report Assistant is simply a summary of the experiment’s questions, diagrams if needed, and data tables that should be addressed in a formal lab report. The intent is to facilitate students’ writing of lab reports by providing this information in an editable file which can be sent to an instructor.
Explain why you did this…show more content… B. Explain what you learned from the online human heart dissection.
I learned on the online human heart dissection how the heart blood flows works, the anatomy, the four valves, four chambers both left and right (two atriums and two ventricles) structures operate, muscle structures, ridges of the ventricles and septum, and the lungs work together for blood flow.
Exercise 3: Sheep Heart Dissection/Cat Heart
Dissection and Comparison Questions
A. Compare the structure of the fetal pig heart and sheep heart. How are they similar? How are they different?
They both share the same anatomic structures, seeing as it is a characteristic of mammals to have four chambered hearts. The main difference is that the sheep heart is bigger than the fetal pig's.
B. Why is the heart referred to as a double pump?
The heart is referred to being a double pump because of the division. The heart is divided into two pump portions, with the left side contains oxygenated blood and the right side contains the deoxygenated blood. One right pump carries the deoxygenated blood to the lungs while the left pump will carry the oxygenated blood to the other parts of the brain and body system organs.
C. There are four valves in the heart. Name each valve, list its location and give its function.
The heart is divided into four valves. The four valves are two on the right side that carry the
