Structure of the Digestive Tract. The digestive system is just a tube within a surrounding tube called the body. Note the genital opening in Figure 22. Digestive System: It’s important to note that different types of diets require different systems, and a large amount of variation is present. Let’s take a look at how the poultry digestive system works. Even without teeth, chickens have one of the most efficient digestive systems in the animal kingdom. It starts with a mouth and ends with the anus.What goes on in between depends on the insect, its life stage and what it eats. Obtaining food 2. Around 4,600 cockroaches are living aside human habitats. The Drosophila intestine is a complex organ consisting of multiple cell types of heterogeneous developmental origin. The specific features we were looking for were: The spiracles, closable holes in the abdomen and thorax of the insect in which oxygen enters the insect; Trachea, ribbed tubules of chitin which are attached to the spiracles DIGESTIVE SYSTEM The digestive tract not only aids in obtaining, processing and digesting food molecules - It is the largest endocrine tissue in both humans and insects. The Alimentary canal has been divided into three main parts: Foregut Accessory organs such as the liver, pancreas, and gallbladder are also an important part of the digestive system of frogs. The digestive system is involved in: 1. 4. Food is taken in with the beak, which is the perfect tool for pecking feed in crumble or pellet form, small grains, grass or insects. The digestion of food would take place in the cavities specialized or combined together. One of the main parts of the digestive system is the alimentary canal, a tube that runs from the mouth to the anus. Locust Dissection The Aim The aim of this dissection was to observe the gas exchange system of the locust. digestive system functions to altered the chemical and physical composition of food so that it can be absorbed and used by the body; ie Functions of Digestive System: 1. physical and chemical digestion 2. absorption 3. collect & eliminate nonuseable components of food Human Anatomy & Physiology: Digestive System; Ziser Lecture Notes, 2014.4 2 insects digestive system 1. Cockroaches would fall under the category of insects of the Blattodea order. Insect Respiratory System: A complex of networked tubes known as a tracheal system Spiracles Spiracles are the valve like opening where air enters the body Spiracle Internal anatomy: Compared to us, the nervous system and circulatory system are reversed The hearts in the abdomen help pump the fluid forward into the aorta Mechanically breaking it down into smaller particles that facilitate digestive enzymes acting on them 3. Be careful to avoid cutting through the atrium. Gently separate the reproductive system from the digestive system. PRESENTATION ON DIGESTIVE SYSTEM OF INSECT • By M. Furqan.Ali 2. This incision will detach the entire reproductive system form the rest of the animal (Figure 23). The major organs involved in the process of digestion in frogs include mouth, pharynx, esophagus, stomach, small intestine, large intestine, and cloaca. DIGESTIVE SYSTEM 3.
