Student Name: Name of Group Members: Date: Introduction: In this lab‚ you will be examining many characteristics of a rat’s anatomy. Dissections help researchers get a 3-dimensional picture of how the systems of a body work together. Now you’ll have the opportunity to see how the respiratory‚ digestive and circulatory system are arranged spatially. The Classification of the Rat (Rattus norvegicus): Kingdom: Animalia Phylum: Chordata Subphylum: Vertebrata Class: Mammalia

Dissection is a common practice among high schools in the biology class. With new technology arising‚ there has been many debates that have been presented looking at the pros and cons of such behaviour. Millions of animals are killed annually‚ there are little to no control measures in place‚ and animals suffer for the use of dissection among students. In the United States‚ six million frogs are dissected annually in high schools. An additional amount is used in elementary and universities across

Chicken Wing Dissection The chicken wing dissection was very helpful in understanding not only the muscular system but also the skeletal system. We looked at both the bone and the muscles of the chicken wing. We noticed many different things that we had been studying in class. In this dissection we studied structure and function of a chicken wing‚ which is comparable to that of the human arm. First‚ we removed the skin of the wing with the tools provided for us. We examined yellowish tissue clumped

Dissection is the process of studying and disassembling a deceased animal or plant to enrich the understanding of the anatomical structure. As a student I do enjoy dissecting animals because it does give me a good understanding of what our organs and body parts look like and how they are all related. In contrast to that I do not believe it is ethical to do dissections on dead animals and plants. Obviously when you think about what you are doing you soon realize that cutting an animal open is an

FETAL PIG ESSAY Through the dissection of the fetal pig‚ we were able to compare and contrast the structure and functions of the organs to those of a human. We dissected the pig and observed all the exterior and interior structures. The fetal pig’s structure was almost identical to the human body. Since humans and pigs are both mammals‚ it can be very useful to study the fetal pig. We dissected the pig so that we should see the skeletal and organ structures that we learned about in class. Because

Such experiments were the main contributors to our current knowledge in some fields of science‚ especially medicine. Dissections performed on rabbits‚ mice‚ chimpanzees‚ and other animals‚ along with some imagination may have helped shape what we knew about the human anatomy back in a day‚ but only up to a certain extent. In the end‚ in order to learn more about the human body‚ dissection accompanied by experimentation had to be done on humans themselves.

Study Of Cocoons. A pupa is the life stage of some insects undergoing transformation. The pupal stage is found only in holometabolous insects‚ those that undergo a complete metamorphosis‚ going through four life stages; embryo‚ larva‚ pupa and imago. Pupa of the rose chafer beetle Characteristics:- In the life of an insect the pupal stage follows the larval stage and precedes adulthood (imago). It is during the time of pupation that the adult structures of the insect are formed while the larval

PRE-LAB: 1. The value to students of dissecting a mammal‚ especially a pig because most students like to learn hands on giving them an opportunity to dissect a pig gives us a chance to give us a visual and help us understand the systems in a mammal. 2. My feeling about dissecting a pig is nervous because it is a real pig even though it is fetal. I feel like I will end up cutting the pig in the wrong spot. I am also excited to dissect the pig because I have never experienced this before and think
