When your lab report is complete, submit this document to your instructor in your assignment box.

2. Use this Lab Report template for all of your labs. Do not turn in separate documents for each lab or create your own document! Each lab is easily identified within this document. Note: It is a good idea to read over this template before performing your labs, so that you know what to expect.

Your Lab Summary: What were the most significant 2 or 3 concepts you learned while doing this Lab?

Complete Table 2 and answer Post Lab Questions 1 through 4 in complete sentences on the Week Three Lab Reporting Form.

4. Describe the hormonal control of the secretion of bile and pancreatic juice during the digestive process.

The cat dissection is the culminating component of this course because it solidifies our knowledge of anatomy and physiology by applying it to a tangible specimen. Mammalian dissection provides an experience that two dimensional diagrams are incapable of and serves as an indicator of whether entering a profession that involves the application of anatomy and physiology is suitable for students in this course. The cat dissection builds on the previous dissections of the fetal pigs and other individual structures throughout the year by applying them to a cat that shares similar well-developed organs and muscles found in human anatomy. I found value in recognizing the similarities and differences not only between human and cat anatomies, but also

Describe the development and function of the endosperm. Distinguish between liquid endosperm and solid endosperm.

This system enables specific signals to be sent and received by cells and tissues that are distant from one another. The endocrine system controls activities that take place in the body by releasing mediators, which are known as hormones. A mediator molecule can also be known as a hormone and it is released into one specific part of the body and normalizes the activity of cells in other parts of the body. Once a hormone is released it is transported to the target cells through the circulating blood in our bodies. Hormones in the body are significant in the processes of regulating growth, development, metabolism and

Introduction The goal of this lab was to dissect and isolate the muscles and organs of a cat. Dissection is the act of cutting into a specimen to learn the anatomy of it upon other things. Isolation is the act of separating one body part from another. The groups were to explore different areas of the cat as a class.

1. Lab reports are to be computer-generated and double-spaced. All sections of the report must

At first on hearing we are doing a pig dissection I was pretty excited. I remember in seventh grade we did a frog dissection. I was okay with it, but I thought the frog was to small. Moving around in the frog was hard and was confusing. I was pretty excited about the pig dissection knowing that it will be bigger than the frog. I was not scared or nerovus about this dissection at all as it is a nice way to learn about other animals and species that live on Earth.

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.

Homeostasis is a biological process that maintains a constant internal environment, regardless of what is going on in the external environment. This process ensures the bodily functions and chemicals are kept in a state of balance which in return allows the body to function optimally. Homeostasis requires coordination of the hormonal (endocrine system) and nervous systems, which together regulate the activity of the body’s organ systems. The regulatory activities are constantly adjusted in response to stimuli (change) from both the internal and external environment. A change influenced by the external environment can cause a state in the body that will take it away from the normal, the body will act to counteract this change and return the internal environment back to a steady state. This is negative feedback. Negative feedback has a stabilising effect reducing changes from a set point and returning internal conditions to a steady state. Most body systems e.g. controlling blood glucose levels, obtains homeostasis through negative feedback which makes the negative feedback system critically important in obtaining homeostasis. However there is also positive feedback which is a system that results in the escalation of a response to a stimulus. It causes instability in the system and is used when there is a specific outcome required. Positive feedback ceases once the natural resolution is reached e.g. baby is born, pathogen is destroyed, blood clot forms. This system is not used

The bile moves into the gallbladder via tiny tubes. The bile is stored in the gallbladder and waits, becoming concentrated, for the signal to be released into the duodenum aiding in digestion. Without bile, the body could not digest fats, as fats do not absorb into water. The bile acts as a detergent and allows the two to mix.
