The digestive system, in organisms like the mink and human, is supposed to break down the food being eaten to transfer into energy. This energy helps other functions of the body that would in turn keep it alive. The digestive system includes organs such as the stomach, intestines, liver, etc. Digestion starts at the mouth, though.
With the observation of the digestive organs of the mink, an individual can see that the entire liver is the darkest looking color of the organs in the gastrointestinal tract and the second largest to the intestines. It has five lobes that branch out towards the middle, right, and left which make up the are the median lobe, right lateral lobe, quadrate lobe, left median lobe, and the left lateral lobe. The stomach is what would come after by looking at the mink from top to bottom. It is smaller in size and compressed, due to the fact that there is no food inside, therefore it looks about the size of half the liver. It looks like the letter J but it is placed laterally on the body. Also, it has a soft light pink color.
The pancreas can be seen under the stomach and it has a yellow color, much like the color of fat, and it’s about the size and shape of the stomach, although most of it is seen behind it.The spleen, located on the left side of an organism, like the mink or human, is next to the pancreas and it looks like the same dark color more or less of the liver. It is shaped like a circle and is smaller than the stomach. The rectum looks like a long skinny noodle and it is a very light peach color. In length it is larger than some other organs. The small intestine looks like a really long noodle and it is mostly pink while being the largest in length of all the organs in the digestive system. The ...

.... Whereas, in humans it is much easier to visualize the difference inside or cut out. In addition, the small intestine was about six times the body length of the mink, although, in humans the small intestine is three to four times the body length.
One of the few differences in mink and human digestive organs is that the large intestine is much smaller in the mink and doesn’t coil around the abdominal cavity like the large intestine in a human organism. Furthermore, the size of the stomach in minks is required in order for them to eat much larger prey and be able to store more energy. The pyloric sphincter, which is useful in preventing the bringing back the food from the small intestine back into the stomach, plays a more significant role in the digestive process of the mink compared to a human. The mink and human are similarly related on an evolutionary chain.
Once the external anatomy was observed the pig was then laid down on the dissection pan and held down by rubber bands exposing the ventral side of the pig. Then the cardiovascular and digestive systems were analyzed. The fetal pig did in fact have small teeth which were fairly sharp. Before the lab I wasn’t aware of the intricate details of the mouth cavity or that the kidneys were underneath the intestines. The hardest part was locating the trachea and the gall bladder. Additionally actually feeling the heart and various parts of the fetal pigs internal anatomy made learning the parts of the body
In the muscular system the main differences between minks and humans are mostly the size and shape of each muscle. However, for example the temporalis differs in that it has different locations within the mink and human. In minks the temporalis is located on the dorsal side of the skull while, in humans it is located on the later side. Also the romboideus complex muscles differ in location as well. In humans these muscles are located in the upper section of the dorsal side while, in minks they are found closer to the neck. Another example of differing locations if that of the levator scapulae. Though the functions are the same which is to elevate the scapulae and shoulders, in humans it is located in the upper section of the dorsal side of the body behind the neck. In minks the levator scapulae is located lower down the back. The main similarities of the muscular system between minks and humans are both the name and functions of the muscles. For instance, the masseter elevates the mandible which helps in raising the lower jaw to close. Also there are the obliques and transversus abdominis that encloses the abdomen while the diaphragm separates the thoracic and pelvic cavities. The gastrocnemius muscles also have similar functions between the mink and humans which are the plantar flexion of the foot at the ankle and the flexion of the leg at the knee joint.
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.
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.
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.
...sheath encloses the penis of a mink and is held along the ventral wall of the abdomen. Male humans do not have this, and have much smaller penises relative to their body size. The percent of body length of the average mink and human penises are approximately 15 percent and 8 percent.
A Mink is a Carnivore found in many parts of the world. Two animals are branched out of the name “Mink”, there is the American Mink and the European Mink. The differences between these two animals include that the American Mink is larger in addition the difference can be seen in their skulls as the American Mink has a mandible that attaches to the rest of the skull differently than the European Mink allowing for greater range of motion ones it will bite. The American Mink is a semiaquatic mammal in the Mustelidae family. The mink has a long slender body and had long thick shaggy tail.
As you have read this essay you have become almost an expert. Now, you know the similarities, differences, and how the circulatory and digestive systems work together. They are very important considering you couldn't live without the digestive to digest food and the circulatory to circulate blood for your
The digestive system is a group of organs that works together to convert food into energy and basic nutrients that will feed the entire body. The digestive system breaks down food so nutrients can be absorbed by the body. The digestive system has three main functions. First, it ingests food then breaks it down so nutrients can be absorbed and it also eliminates what cannot be digested.
Digestion is defined as the process of transforming foods into unites for absorption. The Digestive System is a complex network of organisms that have six major processes: The digestion of food, the secretion of fluids and digestive enzymes, the mixing and movement of food and waste throughout the body, the digestion of food into smaller pieces, the absorption of nutrients, and the excretion of wastes (Inner Body (1).)

Length and complexity of digestive system- the giraffes digestive system consists of 4 stomachs as one has adapted to its twigs and leaves diet. The intestine measures up to 80m in length and has a relatively small large intestine and liver. Surprisingly the gallbladder is where the giraffe’s calf grows during pregnancy but might disappear before birth.
There were a few observations proven to be different between the rat’s anatomy in comparison to the human anatomy. First of all, the rat has no gallbladder present in it’s anatomy which a human does. Secondly, the rat’s lungs appeared dark red in color where as a human’s lungs are pink in color. Also the rat’s liver has more lobes as does their lungs compared to a human’s liver and lungs. Besides these said differences, the rat’s anatomy is basically very similar to that of the human body.
The digestive system is very responsible for taking the whole food that people eat and turns them into energy and nutrients to allow the body to function, grow, and fix itself. The six primary processes of this system are ingestion of food, secretion of fluids and digestive enzymes, mixing and movement of food and waste throughout the body, digestion of food into small pieces, absorbing the nutrients, and the elimination of wastes. Ingestion is the first function of the digestive system, which is also known as the intake of food. The mouth is the reasoning for this process because through the mouth is the way food enters the body. The stomach and the mouth store food until your stomach is ready to digest the food that was just eaten. The reason why people can only eat a few times a day is because your body can only allow a certain amount of food depending on your body weight and type, and it cannot ingest more food than it can process at one time. The next step in Secretion, this happens in the course of the day. The digestive system secretes about 7 liters of fluid daily, but these fluids include saliva, mucus, hydrochloric acid, enzymes, and bile...
The excretory system, which includes the rectum and anus helps the digestive system by getting rid of waste and the digestive system helps the excretory system by breaking down food to be eliminated from the body. Wow! The human body wouldn’t be able to work without one or the other. Anyways, I hope you enjoyed reading my journey throughout the human digestive system. I hope to write again from where my next journey from here will begin- perhaps it will be in the ocean or along Sydney Water pipes. Until next
