The next system I dissected was the respiratory system. My first task was to find the trachea as well as the esophagus. My goal was to compare the structure of each. I found the trachea to be wider, stronger, and it had a bumpy surface. The structure of the esophagus is small, but versatile which allows it to move easily. It is also flat and full of muscle. This allows for food to digest before it enters the stomach. While dissecting the respiratory system, I continued to study the trachea, as well as the lungs and bronchi to see how their structure related to their function. . As mentioned above, the trachea is a wide and strong part of the respiratory system. The structure of the trachea is related to the function because it allows for the fetal pig to receive proper air passage through the lungs. Next, the structure of the lungs consist of four lobes in the right lung, and two or three lobes in the left. “The lungs in the fetal pig are small and fairly solid because they’ve never been …show more content…
Both the kidney of the pig, and the kidney of the sheep shared similar structures and shapes. The shape of these kidneys are both bean like. The pig’s kidney was much less significant in size compared to the kidney of the sheep. They are both extremely dark red, with a tint of brown. Their odd shape allows for them to function correctly and filtrate urine production and blood. The kidneys of the fetal pig can be located on both sides of the spine behind the abdominal organs. The kidneys’ are a vital part in the process of removing urine from the body. The path that urine takes to exit the body is very specific. First, the urine is in the kidney. Next, the urine goes into the ureters, followed by the bladder and urethra before exiting. I have learned through this experiment that the kidney is a very unique and vital organ that performs many
Over these 15 consecutive days our criminal justice class has watched the decomposition of 9 still born piglets, which were laid out in a specific way, with specific wounds. Piglet 10 was put into a box at the beginning of the experiment, and was not revealed until the end of it. Each piglet was in its own condition. Piglet 0 was naked in a box, Piglet 1 was naked on the grass, piglet 2 had 1st, 2nd, and 3rd degree burn all over its body, it too was laying on the grass, piglet 3 was stabbed behind right shoulder, also lying on the grass, piglet 4 had a .380 bullet would on its side, it was laying on the grass, piglet 5 was clothed on the grass, piglet 6 was naked piglet on the black top, piglet 7 was clothed on the black top, piglet 8 was suspended in the air with clothes on, and piglet 9 was suspended in the air naked. At the beginning of the experiment we hypothesized on theories we now know the answer too.
There is a pattern for all animals like all the other things we talked about such as
After observing many of the outside traits of our fetal pig, we were now ready to really look beneath the skin. The skinning lab is very important because it is the layer that covers much of the muscular system that we wanted to observe. By removing the skin by pulling and cutting, we would then increase our knowledge by getting our hands dirty and internally observing the pig. Under the skin, we would be able to view some of the many muscles that we learned in the past chapters.
“Fetal Tissue Fallout, R. Alta Charo, J.D., September 3, 2015” In this article R. Alta Charo states that we have a right to use fetal tissue for research and therapy (Fetal Tissue, 1) The article goes into how a lot of people find this to be a moral issue and a matter of the conscience and explains how the antiabortion activist that don’t agree with the research are actually benefitting from the fetal tissue. They argue that the research supports abortions but have taken part in receiving vaccines and therapy that comes from the research. R. Alta Charo begins by talking about the argument over the antiabortionist activist who pretended to be a research company representative and gave out false, edited information from a Planned Parenthood video that goes over the services they provide.
Chapter 5: 1: Both the trigeminal and facial cranial nerves are the most complicated because the start from the brain and split into different parts of the body. 2: The structures are the ears, larynx, throat and jaws. 3: The Hox genes are like blue prints for development for embryos. They are important because without them the embryo wouldn’t know how to develop. 4: Amphioxus is a small invertebrate, yet shares many characteristics with vertebrates.
40 developmental assets reflect what you learned in your childhood life. In the novel The Pigman, these assets are shown by all characters. In this novel John allows you to explore the 40 developmental assets, caring, other adult relationships, and honesty. In the beginning of the novel John does not really fit either of those, but as he grows up, he starts to fit into those assets. He was a very bad kid until he met Mr. Pignati, Mr. Pignati was a very kind man who cared for John very well.
Then the travel time from the location of the deceased to the person in need, also gets added. Now if the person is living they can bring them to the hospital, match blood samples, and donor criteria. Once finalized, with both people in the same hospital, they begin the procedure; in this case the kidney stays max 1-2 hours outside the body. This result in the low chances of a viable organ from the dead to reach and save the life of the living.
I should have listened to my parents when they scolded me to “Finish your plate, I can still see three pieces of broccoli.” What can I say? I was a stubborn child who, to this day will not touch anything with a hint of potato. I never realized how vital vegetables were to a diet until that’s all I could, or would, eat. My epiphany began in my sophomore biology class, as my favorite teacher excitedly stood in front of the classroom labs to declare “We are starting dissections!”
Digestive system function Your digestive system is uniquely constructed to perform its specialized function of turning food into the energy you need to survive and packaging the residue for waste disposal.(1) Digestive system organs Mouth The mouth is where the digestive system begins. Start the process of digestion by enzymes released into the mouth Epiglottis
Within the organs of the fetal pig, its colon is different in structure than that of human since the fetal pig colon is spiral. The fetal pig uterus has two big horns in addition to the body while the human uterus has small uterine horns. The large uterine horns on the fetal pig allow for a litter of 8 to 10 pigs. In fetal pigs, “the brachiocephalic artery splits into the right subclavian artery and the bicarotid trunk which then splits into the right and left common carotid arteries” (“Human/ Pig Comparisons”). Nonetheless, humans do not have a “bicarotid trunk and instead the left common carotid artery branches directly from the aorta” (“Human/ Pig Comparisons”).
The study of the comparison of structures of different organisms is called comparative anatomy. Comparative anatomy shows evidence for evolution, and it indicates that many organisms have a common ancestor. In addition, it is used by scientists to classify organisms based on related characteristics of their anatomical structures. Similar bone structures in the forelimbs of cats, whales, bats, and humans are an example of comparative anatomy. Despite the fact, these appendages are made of the same basic parts; they all have completely diverse functions.
Based on the data given, it could be concluded that when unfiltered blood enters the kidney, it is being rid of its waste, essentially filtering it. The blood travels through the nephron, which then sends the filters blood out of the kidney,
Some examples are the circulatory, the excretory, the muscle, and the digestive systems. For example, the digestion system is an organ system that digests the food a person eats. Some organs in the digestive system are the esophagus, rectum, stomach, liver, gall bladder, pancreas, large intestine, small intestine, and appendix. The digestive system is very important because without it, organisms would not be able to digest food. Food would just sit inside the body or go through it without the body taking any energy for fuel.
The transverse (or axial) plane divides the body into superior (upper) and inferior (lower)
The nerve supply also comes from her celiac plexus innervating the liver mixture of sympathetic and parasympathetic fibers. These ribs reach the liver by the hepatic artery. Liver Physiology The liver performs many functions in the body such as: • Production of bile: The liver excretes bile to the bile duct and thence to the duodenum. Bile is necessary for digestion of food.
