Digestive system – *The digestive system is composed of the mouth cavity, oesophagus, stomach, small intestine, colon, and glands. *The mouth cavity is bounded by the upper and lower jaws. *The tongue islong, slender and deeply forked. It has a muscular sheath into which it may retract. The tongue is sensitive and is used as tactile organ. *The oesophagus is thin walled and runs adjacent to the air sac from …show more content…
*The oesophagus opens into a dilated muscular and elongated part called stomach. *The junction between the oesophagus and the stomach is not well marked, and the stomach itself is not very …show more content…
* The wall of the trachea is supported by many tracheal rings.Trachea ends near the heart, where it branches into two bronchi. * The left bronchus leads to the left lung, which is very small or completely vestigial. *In most snakes, the left lung is completely vestigial. *In Boas respiratory system and pythons it is a third of the size of the right lung while in sea snakes the right lung stretches the entire length of the body to aid in buoyancy *The right bronchus leads to the right lung, which is elongated. *The anterior part of the lungs is vascular and functions in gas exchange, but the second half of the lung is nonvascular. *The air sac acts as a hydrostatic function in most snakes. It
Northern Pintail: Skeletal System
1436 Words | 6 PagesThe Pintail has a rather complex system in which the blood is distributed. There are many arteries that allow the bird to live and operate under the extreme conditions it can be exposed to. The Carotid artery takes the blood to the head and brain region of the body. Another artery in the body is the Brachial which supplies blood to the wings.
Asthmatic Episode Analysis

Photosynthesis: The Biological Process Of Respiration
1229 Words | 5 PagesContraction of muscles in the abdomen compresses the internal organs and forces air out of the tracheae. As the muscles relax, the abdomen springs back to its normal volume and air is drawn in. Large air sacs attached to portions of the main tracheal tubes increase the effectiveness of this bellows like
Summary: Skeletal Muscles
1789 Words | 8 PagesThe trading of gasses in the middle of air and blood happens cross the dividers of respiratory alveoli. Alveoli are microscopic flimsy walled air sacs that give a colossal surface zone to gas dispersion. The locale of the lungs where gas trade with the blood happens is known as the respiratory zone. The trachea, bronchi, and bronchioles that convey air to the respiratory zone include the leading zone. The thoracic cavity is constrained by the mid-section divider and diaphragm.

Ventilation Lab Report
1099 Words | 5 PagesThe walls of the alveoli actually share a membrane with the capillaries in which oxygen and carbon dioxide move freely between the respiratory system and the bloodstream. Oxygen molecules attach to red blood cells, which travel back to the heart. At the same time, the carbon dioxide molecules in the alveoli are blown out of the body with the next exhalation." (Dugdale, 2012) Ventilation is another fact because if this not happen our body will be full of carbon dioxide and the oxygen will be down. Many times when the people here ventilation they get confused and think that they are talking about respiration that is not correct, is correct say that ventilation is similar to breathing but no to respiration, they are different "Movements of the ribs, rib muscles and diaphragm allow air into and out of the lungs.
Dynein Motor Protein Literature Review
1203 Words | 5 PagesIn particular there are many cilia and flagella present in the lung. Axonemes make up the cilia and flagellum. They are present in 9 sets of doublets. As shown in Figure 1.1 (a). Axonemal dynein proteins are attached to doublets on the inner and outer arms.
Pyloromyotomy Essay
754 Words | 4 PagesPATIENTS AND METHODS This an interventional comparative randomized prospective study conducted on 40 patients with infantile hypertrophic pyloric stenosis indicated for pyloromyotomy. 20 patients underwent laparoscopic pyloromyotomy (LP) and the other 20 patients underwent umbilical pyloromyotomy (UP). Patients characteristics including,age,gender ,gestational age (full term, preterm), associated comorbidities were documented. Intraoperative details e.g. operative time and complications and postoperative outcomes e.g.; time to full feedings, incidence of postoperative vomiting, hospital stay and wound dehiscence were recorded.
Digestive System Research Paper
917 Words | 4 PagesThe 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.
Earthworm Observation
518 Words | 3 PagesThe mouth is the first part of the digestive system that takes in the food leading it to the pharynx. The pharynx is a tube-like structure that pumps the food and soil into the esophagus. There, the calciferous glands which is found in the esophagus, releases calcium carbonate. This helps get rid of any excess calcium in the earthworm’s body. Similar to the pharynx, the esophagus is a tube like structure that leads the food to the crop.
Mesozoic Era Essay
2439 Words | 10 PagesWhile swimming up or down through the water, the nautilus uses its siphuncle to suck in fluid or draw it out, allowing it to adjust its overall buoyancy. Comparison of Anatomy of Ammonites and Nautilus Despite the fact that the Ammonites and Nautilus may appear the same, they are easily distinguished by notable location and function of their anatomical features. Siphuncle
Total Lung Capacity Essay
785 Words | 4 PagesThe heart may have the sinoatrial node (SA node) to trigger contraction, but in order for us to breath our nervous system has to signal for us to begin the process of ventilation (breathing). Our brain stem has three parts to it, but only the pons and medulla oblongata play a key role in breathing. The medulla helps set the respiratory rhythm by receiving and sending impulses to a bundle of neurons called the ventral respiratory group to the phrenic nerve to bring about contraction in the diaphragm and external intercostal muscles. All this only happens though due to the sensors of the chemoreceptors. The chemoreceptors located in the medulla and carotid and aortic bodies detect a rise in carbon dioxide (CO2).
Gyrodactylus Research Paper
730 Words | 3 PagesMy topic is about gyrodactylus species. Today I will go over the classification, the morphology, the gyrodactylus life cycle and finally, the infections and diseases. First, about the classification, Gyrodactylus sp. belongs to phylum Platyhelminthes with suphylum Neodermata, class Monogenoida, order Gyrodactylidae and genus Gyrodactylus. There has little controversy about the naming of class of these species. The class Monogenea was attributed by van Beneden (1858) and it was used to be an appropriate name in common use; but Bychowsky introduced the name Monogenoidea which is considered as an emendation of Monogennea van Beneden (1858).
Essay On Human Body
924 Words | 4 PagesThe digestive system is located around the stomach area. Along with the digestive system, many other organ systems all work together to create an organism. An example of this would be if a person eats a sandwich and then goes for a run. During the run, the circulatory system helps the body breathe, the muscle system helps the bones move, and all the while the digestive system digests the food. Later on, the excretory system gets rid of the waste, or food that the body can’t use for nourishment.
Liver Anatomy And Physiology Essay
974 Words | 4 PagesRelations 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.
