The purpose of the experiment was to understand how strong a bessbug by using weights and observing the time the best bug takes to travel to a certain distance.
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
The food then travels into the oesophagus. Your oesophagus is located near your trachea (windpipe). The epiglottis separates the nasal cavity and the lower airway from the passage of food whilst swallowing. The contractions of the muscles in your oesophagus push the food down your oesophagus and into your stomach. Your stomach is a hollow organ that holds food whilst it is being broken down by the enzymes. There is also strong acid released by the glands in the lining of the stomach which helps break down food into a more useable form and also aids in the destruction of most ingested bacteria. After the contents have successfully been broken down they are released into the small intestine. The small intestine is a 22 foot long tube that helps to break down the food with enzymes released from the pancreas and bile released form the liver. In this organ the process of Peristalsis is at work, pushing the food further and further through the small intestine towards the colon. These movements are stimulated by the presence of chyme. The small intestine begins with the duodenum which has the large responsibility of continuing to break down the food. The jejunum and ileum are
Gastric bypass surgery makes your stomach smaller. This causes you to feel full with less food so you consume fewer calories. The procedure also bypasses part of your small intestine, so fewer calories are actually absorbed into your system. Fewer calories will ultimately lead to weight loss.
In every part of the surrounding, in which humans dwell in, no matter in water, land, air, or elsewhere, there reign tiny yet complex lives. The in depths study of these living organisms bring human a face to face consequence with an astounding miracle of the creation of God. The astounding part of the living organisms have led us some understanding of the awe-inspiring structure of every life from as small as 0.0000001 to over 0.1. These photomicrographs unveiled the miracle and astounding lives as illustrated below.
The pleura (lining of the lungs) is actually comprised of two parts. It has an inner (visceral) layer which is next to the lung and an outer (parietal) layer that covers the chest wall. The two layers slide over each other as we breath and membranes in the lungs
A pneumothorax is a life threatening disease that results in a restrictive lung disorder. This condition is associated with atelectasis, chest wall expansion, and a decrease in cardiac venous return. Often caused by smoking, a pneumothorax can be detected from pulmonary function testings, arterial blood gas interpretations, and chest radiological findings. While some mild cases can resolve on their own, there is a current treatment process and protocols for managing symptoms brought with the disease. When a pneumothorax is detected, immediate action must be taken as death can occur. In addition, reoccurrence of the disease is highly common.
Entering the through the Lower esophageal Sphincter (LES) wasn’t entertaining but once you get in it’s like rippled effect of the water except that is a combination of red and pink. We’re finally in the stomach we will just hang in here an hour or two. Once we travel through the Rugae it will produce the enzyme Pepsin. So I can be prepared for the small intestine.
The most common version of this surgery is known as the Roux-en-Y or stomach stapling. As the alternative name states, the stomach is stapled or sewn to be smaller reducing the amount of food that is able to be taken in. This allows the individual to feel fuller faster and eat less. This is but one part of the procedure. The secondary step is to reduce the length of the small intestine. The stomach pocket is attached to father down the digestive
Incidence of complication due to the procedure of CT guided transthoracic fine-needle aspiration cytology of lung lesions.
Relations with the diaphragm and heart liver supplement neighboring organs. The base of the liver opens into the hepatic hilum, which is but the entrance area of the omentum (omentum) lower with the portal vein, hepatic artery and hepatic duct outlet. The omentum (omentum) lower (fixed at a protrusion of the lower side omental called tuber) lining the bottom of the grooves of the base of the liver (venous ligament sulcus, groove round ligament) and reaches the rear edge of the bottom face where the peritoneum overlying coating passes the diaphragm and the back wall forming hepatorenal ligament. Ahead of the peritoneum lining the diaphragmatic surface to its upper limit, where jumps take the abdominal surface of the diaphragm. Between the two folds of peritoneum onto the surface of the liver to the diaphragm is comprised bare surface of the liver, an area in which the peritoneum covering the liver capsule. In this area the inferior vena relates receives liver and the hepatic veins.
The first phase of digestion is the cephalic phase. Neurogenic signals from the cerebral cortex are transmitted through the vagus nerve to the stomach and stimulate gastric secretion. The cephalic phase occurs from smelling, seeing, thinking about and tasting food, prior to further digestion of food in the stomach.
In this case, one sphincter opens and makes the oesophagus able to propel food to the stomach by coordinated contractions and relaxations of its muscular lining (peristalsis). After swallowing, the sphincters relax involuntarily to allow drink or food to through from the oral cavity into the stomach. When there is no swallowing action, the muscles would close rapidly to prevent the swallowed food or liquid from leaking out of the stomach back into the oesophagus or into the mouth.
Their primary distribution is noted within the mesonephric area, but later they also supply the reproductive glands, suprarenal bodies, metanephros and diaphragm. The number of mesonephric arteries is variable, and it follows the degeneration of the mesonephros with the progressive
Peristalsis is spontaneous or reflexive movements of the longitudinal and circular muscles, that happens in progressive wavelike contractions, fundamentally in the digestive tract but some times it also occurs in other hollow tubes of the body.In the human body esophagus, stomach, and intestines are the main parts in which peristaltic waves arise. These waves can be momentary, local reflexes or prolonged, consecutive contractions that are transmitted to the whole length of the organ, relying upon their location and what beginstheir action.Peristalsis has its importance in movement of food in digestive system, passing of urine from kidneys to bladder, bile passing from gallbladder to duodenum etc. The phenomenon of peristalsis is also feasible
