Anatomical Comparison

The digestive system of a pig is classified as monogastric or non-ruminant, which is having a stomach with only a single compartment, like humans. In addition, the digestive tract of the pig has five main parts, including the mouth, esophagus, stomach, and small and large intestines. Furthermore, the mechanical breakdown of the food begins upon the entrance of the mouth in the digestive tract. Basically, the food is grinded into smaller pieces by its teeth. Next, saliva is produced in the mouth, acting to moisten the small food particles, along with an enzyme that starts the digestion of the starch. Then, the food is pushed towards the esophagus with the help of the tongue. Primarily, the esophagus carries the food from the mouth to the stomach, being a tube, which is carried out with the help of a series of muscle contractions that push the food towards the stomach. Subsequently, after the first of the contractions, swallowing, has taken place, the cardiac valve, located at the end of the esophagus, prevents food from passing from the stomach back to the esophagus. Likewise, the stomach comes next in the digestive tract; it serves as a reaction chamber, adding chemicals to the food. Also, hydrochloric acid and enzymes help break down food into small particles of carbohydrates, protein, and fats. Additionally, some particles are absorbed into the bloodstream, from the stomach, while others cannot be absorbed by the stomach, being passed to the small intestine through the pyloric valve. Moreover, the small intestine aids

For protein digestion to occur in the stomach there are various components that are needed for this process. Those components include gastric/stomach acid (HCL) and

Omnivores are very interesting creatures. We are able to digest most plants and animals and therefore have

In this lab we studied selection and adaptation and we did this by looking at skulls of a variety of species and we categorized them based on their feeding groups. We looked at omnivores, carnivores, and herbivores; however, for our experiments we only examined carnivores and herbivores. The paper we used in this unit was studying the way the shape of a skull can determine and help explain their feeding groups; they used the dog family when doing this study (Slater et al.). For our experiment we used the skulls of carnivores and herbivores provided to us by our lab instructor. In her 1990 book Christine Janis states how there have been several studies that were focused on meat-eaters, or on primates but little were on mammalian herbivores.

According to a “A talk for the Vegetarian Research Group”, by John McArdle says that characteristics of our digestive system indicates that we our omnivorous. Humans have both canine and molar teeth. Canines aren’t used for chopping up leaves. So, the canines can be used for tearing apart, and the molars are used for crushing. This shows that humans have the capabilities to eat both meats and

Carbohydrates are one of the main types of macronutrients that move throughout the digestive system. Starting inside of the mouth, the carbohydrate travels through the body until it gets broken down. The mouth has two forms of digestion, mechanical or chemical. Mechanical digestion includes chewing food, while chemical digestion uses saliva. The salivary glands belong to the accessory organs of the digestive tract, but play a very important role in digestion. They produce amylase, which breaks down the starch amylose and amylopectin into smaller portions. Breaking down starch, is an example of where chemical digestion occurs in the mouth.

Langston Hughes connects with his audience throughout his poetry by focusing on life's matters. He brings out the significance of life by talking about obstacles that many people encounter in their lives. As Ellen Bailey states, "His work as a poet, novelist, dramatist, short-story writer, essayist, editor, and lyricist focused on the lives of lower class black Americans," which is recalled in "The Negro Speaks of Rivers", "and he often spoke out against racial injustice." But this poem is about all of humanity. "Life is Fine" by Langston Hughes is about staying optimistic when being challenged in life because it talks about many scenarios where the narrator wants to give up on life but never follows through because life is too good.

The plant material is broken down by enzymes making the pieces smaller. Mucus is secreted to protect the stomach lining from the acid. The acid kills the bacteria in the food. The enzyme pepsin breaks down any protein that is in the food they eat. The cow has 4 chambers which make up the stomach, this includes the rumen, reticulum, omasum and abomasum.

Two experiments were conducted to demonstrate the processes involved in digestion of carbohydrates and proteins & lipids. Results showed that the digestion of starch is only possible at room temperature (37oC) (highlighting the significance of using 37oC as the incubation temperature since this temperature simulates an environment of normal body temperature) while the digestion of protein assessed using pepsin yielded a positive outcome and correlation in PH to gastric juice, which is secreted by gastric glands.

Humans really do not tear the meat. On the contrary, we soften and pre-cooked the meat before crushing it with our teeth. If humans tear and chew meat, there would not need to cook it at high temperatures and people would eat it raw. Likewise, some of the largest canines in the world belong to herbivorous animals. For example, the hippopotamus diet consists of grass and roots, while the gorilla diet consists of leaves, stems, shoots, and

The chemistry of digestion is dependent on the type of animal as well as the type of food it eats. People think that the bigger the animal is the bigger and parts of the digestive tract there is but it has nothing

Pigs have a digestive system classified as monogastric or nonruminant. Pigs are unique in that they are the only farm animals with saliva containing amylase which is used to decompose starches. The pancreatic fluid helps pigs to digest proteins, fats, and carbohydrates. Pigs gain a lot of nutrients from its small intestines while its large intestines are used to absorb water and hold waste. Pigs are omnivores meaning they can eat both animal and vegetable

Schools Should Give Students ‘Body’ Report Cards According to Michael Gonchar in New York Times “ A growing number of schools are monitoring their students weight and sending updates home much like report cards”. This is because childhood obesity has been a problem and an important issue in a child’s life now more than ever in the United States. The percentage for obesity has tripled since 1970’s. As a result 1 in 5 schools children and young people in the United states has obesity. Schools should give students body report report cards because as a way of monitoring their health, build self esteem, and it a epidemic.

So we don’t need huge sharp teeth like other mammals do to chew their food. Eating meat is just part of us and our nature. With us humans being carnivores it is our nature to eat meat. With the exact definition of carnivore being an animal that eats meat or a meat eater it is literally part of us to eat. We shouldn’t have what is part of us taken away because a few people want all of us to vegetarian. We shouldn’t mess with nature and change what our bodies are made for. Why would we eliminate what has benefited us for over 2.3 million years? There is no point in messing with nature and taken away what is important to your body.

As humanity becomes more civilized, many of us perceive that eating livestock is morally incorrect, but aren’t we are designed to be an omnivore? Our teeth and digestive system serve the purpose of breaking down animal and plant foods and to bring these important nutrients to every part of the body. Despite the fact that, in 2011, U.S. meat and poultry production reached more than 92.3 billion pounds, the ethic of killing and eating animals as well as the concern of the environmental burden caused by the production of meats is debatable. However, animal based diet is necessary for the human body to function properly and we can choose the meat produced from environmentally sustainable farms to avoid the moral ambiguity.
