COMPREHENSIVE DISSECTION OF THE MINK:
Comprehensive Dissection of the Mink: The Digestive System
The American Mink (Mustela Vison) is a small, short haired animal belonging to the Mustelidae family. Much similar to a ferret in appearance the mink has short legs, short hair, a long tail, and a long sleek body with a long neck. It also has a small face, with small features, such as ears, a mouth, a nose and a pair of eyes. This report is consisted of a comprehensive commentary about the differences in the respiratory system between the mink and a human.
In my last report on the mink’s external features in comparison to any human body, although there were clear differences, I was able to find many similarities between the two organisms who seemed very different at first sight. Clearly in this research and lab report about the respiratory system, similarities between humans and minks are not surprising.
Indeed, amongst the many disparities between humans and minks, their respiratory systems are very similar for they are both mammals. The metabolic rate is much greater in mammals than any other class of animals, which means the demand for oxygen is greater. Humans and Minks are both endothermic, so they require a more potent respiratory system. Similar to humans the lungs of minks contain millions of alveoli. Alveoli are tiny sacs that are packed together in clusters as if they were grapes. The tiny sacs or alveoli, allows for a greater surface area for the exchange of gases. Another similarity between humans and minks is the air passage. The first stage in air passage is inhalation which is done through the mouth and/or nose. The air then goes past the pharynx to the larynx, through the glottis (opening for the vocal chords), in...

Students and researchers can learn a lot from observing the mink; unexpectedly I was able to find many similarities between the mink and a human. Humans and Minks are very close in class, which explains their similarities in anatomy. Indeed although these two organisms have a lot in common there are major differences amongst these similarities. The similarities are due to the fact that both humans and the mink are mammals. The differences are due to the differences in environment, habits, size etc... One example is the fact that minks and humans both have lugs of similar shape but different lobes. Each of these similarities and/or differences benefit both the human and the mink, in their own unique way, with each structure having its own function. Overall the mink is a very complex animal and so is an individual.

Purpose: To analyze and discuss the anatomy of the mink in order to compare to that of a human. Even though the mink’s anatomy will be a bit different some similarities could always be found.
Minks and humans share various common characteristics because of their common roots in the animal kingdom. Both Human and Mink species are classified as Animalia Chordata Mammalia until they are separated by order, Humans being primates and Minks being in the order carnivora. It is because of their common roots that they have similar muscles types with similar functions, which help them survive and function throughout their individual habitats. Arm and Shoulder Muscles One of the most important muscles in both a mink and a human are those of the arms and shoulders because of their involvement with movement. One of the primal movers of arm abduction along the frontal plane is the deltoid muscle found in both minks and humans.
The urinary system of a mink is very similar to a human’s urinary system. The purpose of the urinary system is to rid the blood of wastes. The kidneys filter the wastes and water from the blood to make urine. The urine moves from the kidneys through the ureters to the bladder. After the bladder, if filled to maximum capacity, the urine leaves the bladder and goes through the urethra and out of the penis. Making the urinary system for the mink very similar to that of the humans.
The respiratory system has the function of getting rid of carbon dioxide and acquiring oxygen. It works closely with the circulatory system to feed the body the proper amounts of oxygen it needs to function efficiently. The respiratory system of an American Mink is very similar to that of a human in spite of the fact that there are some minor modifications. Both Humans and Minks have two lungs, the right lung is larger and has three lobes and the left lung has two lobes. The reason why the left lun...

The research Horta based his conclusion on is flawed in my opinion, in the experiment conducted by a canine specialist, ten dogs from different breeds were used to determine if the scent of male minks would make them sporadically chase them, during the test eight out the ten dogs blindly ran after the scent. According to me the sample size of ten dogs used in the experiment is too small to validate its claims. According to Jane Fryer from thedailymail.co.uk, the dogs have always jumped from the same side of the bridge, dogs shouldn’t care about which side to jump from considering that minks could potentially live on both sides around the bridge. The dialymail.co.uk is one of first newspapers to catch onto the story of the Overtoun bridge and over the years have published sevral articles about it. Furthermore, there are twenty-six thousand minks in Scotland and quite a few other bridges as well if the director’s conclusion was accurate we would be seeing similar occurrences throughout Scotland and the world. Another oddity about the mink theory is that the dogs who survive the jump climb back up the bridge and jump down again, the scent of the minks should be strongest at ground level why would the dogs need to climb back up just to be back in the same area they were in. Although the director offers a reasonable explanation behind the occurrences happening at the Overtoun bridge he does not provide enough evidence for me to accept his conclusions as there have to be other factors at
The airway includes the nose, mouth, pharynx, larynx, trachea, bronchi, and bronchioles. It carries air between the lungs and the outside elements that surround the body. The lungs are the functional units of the respiratory system and they act as such. They pass oxygen into the body and remove carbon dioxide from the body. Then there are the muscles of respiration. These muscles include the diaphragm and intercostal muscles. They work simultaneously as a pump, pushing air into and out of the lungs during breathing.
The larynx provides a passageway for air between the pharynx and the trachea. The trachea is made up of mainly cartilage which helps to keep the trachea permanently open. The trachea passes down into the thorax and connects the larynx with the bronchi, which passes to the lungs. 3. Describe the mechanisms of external respiration including the interchange of gases within the lungs.

... drawn. What makes us human? Through the examination of human evolution, both biological adaptations and cultural adaptations which are distinct to humans can be recognized. Biologically speaking, humans are unique in that they are bipedal, they have larger brain sizes, and longer leg length. When examining the cultural evolution of humans we have a complex language system, we live in communities, engage in symbolic behavior, and act through emotional impulses. While we are often considered to be superior to all other animals, it is important to recognize that while we are animals, we have very distinct characteristics and adaptations that separate us both biologically and culturally from all other animals.
