What Happens In The Alimentary Canal Apex – Click prefixes, plural forms, and suffixes to display a list of word parts to remember for the digestive system.

The digestive system works constantly, but people rarely appreciate the complex tasks it performs in this choreographed biological symphony. Consider what happens when you eat an apple. Of course, you enjoy chewing on an apple, but within a few hours, you won’t know how your digestive system is working, unless you feel a bit sick and have a stomach ache. You may have forgotten all about the apple, walking or reading or sleeping, but your stomach and intestines are busy digesting it and absorbing its vitamins and other nutrients. When any waste material is removed, the body absorbs all that can be used from the apple. In short, whether you notice it or not, the members of the digestive system perform their own specific functions, which you can use to continue eating.

This chapter examines the structure and function of these organs, and examines the mechanics and chemistry of digestion. The job of the digestive system is to break down the food you eat, release nutrients, and absorb those nutrients into the body. Although the small intestine is the workhorse of the system, where most digestion takes place, and where most nutrients are absorbed into the blood or lymph, each member of the digestive system plays an important role in this process (Figure 15.1) (see ).

Now that you’ve memorized the parts of the word, see if you can break down the digestion terms below and explain them.

You can eat above. Food does not need gravity to reach your stomach. Peristalsis, a wave-like movement of muscles, pushes food along.

It is also called the oral cavity (or oral cavity). The structure of the mouth is shown in Figure 15.2.

(unit = labium). Their outer covering is the skin, which is properly transferred to the mucous membrane of the mouth. Lips are highly vascularized with a thin layer of keratin. Therefore, they are red.

The pocket-like part of the mouth formed by the gums and teeth on the inside and the nostrils and lips on the outside is called the oral vestibule. In the mouth, the opening between the oral cavity and the pharynx (oropharynx) is called the duct (like a kitchen “spout”). The primary opening of the mouth, or oral cavity properly, leads from the gums and teeth to the fossae.

While you are crying, you have no problem breathing at the same time. The next time you have food in your mouth, notice how the arched shape of the roof of your mouth allows you to manage both digestion and breathing at the same time. This arch is called the palate. The front of the palate acts as a wall (or septum) between the oral and nasal cavities, as well as a hard shelf against which the tongue can push food. It is formed by the maxillary and palatine bones of the skull and is known as the hard palate due to the structure of the bone. If you roll your tongue along the roof of your mouth, you will see that the hard palate ends at the back of the mouth, and the tissue becomes fleshy. This part of the palate, called the soft palate, is made up mainly of skeletal muscle. So you can inadvertently break the soft palate—for example, by crying, swallowing, or singing (see Figure 15.2).

A fleshy ball of tissue called the uvula runs down the center of the back of the soft palate. Although some have suggested that the uvula is a nervous organ, it has an important purpose. When you swallow, the soft palate and uvula move up, preventing food and liquids from entering.

. Unfortunately, it can also contribute to the sound produced by rabbits. Two muscular folds extend downward from the soft palate, on either side of the uvula. Anteriorly, the palatoglossal arch is with the base of the tongue; Behind it, the palatopharyngeal arch forms the superior and lateral margin of the ducts. Between these two arches.

You may have heard that the tongue is the strongest muscle in the body. Those who claim it are citing its strength in proportion to its size. Although it is difficult to assess the relative strength of various muscles, it is undeniable that the tongue is the workhorse, facilitating digestion, mechanical digestion, chemical digestion (oral lipase), sensation (taste, texture, and temperature of food). ), pass by. , and playing.

The tongue is attached to the mandible, the styloid process of the temporal bone, and the mandible. The hyoid is unique because it only indirectly articulates with other bones. The tongue is placed on the floor of the oral cavity. The median septum extends the entire length of the tongue and divides it into symmetrical parts.

The top and sides of the tongue are covered with papillae, extensions of the lamina propria of the mucosa, which are covered in it.

The glands continuously secrete saliva, either directly into the oral cavity or through indirect ducts, even when you sleep. In fact, an average of 1 to 1.5 liters of saliva is produced each day. There is usually enough saliva to moisten the mouth and teeth. When you eat, you salivate more, because saliva is needed to moisten and start the chemical breakdown of food.

. A small amount of saliva is also secreted from labial glands in the lips. In addition, the buccal glands in the cheeks, the palatine glands in the palate, and the lingual glands in the tongue help to ensure that all parts of the mouth have an adequate supply of saliva.

The pharynx (larynx) is involved in both digestion and respiration. It receives food and air from the mouth and air from the nasal cavity. When food enters the throat, involuntary muscle contractions close the airways. A short tube of skeletal muscle enclosed by a mucous membrane, the neck runs from the mouth and nasal cavity to the opening of the esophagus and larynx. It has three sub-sections. The upper part, the nasopharynx, is only involved in breathing and speech. The other two subsections, the oropharynx and the laryngopharynx, are used for breathing and digestion. The oropharynx begins below the nasopharynx and continues with the laryngopharynx. The lower border of the laryngopharynx connects to the esophagus, while the anterior border connects to the larynx, allowing air to enter the bronchial tree.

The esophagus is a muscular tube that connects the throat to the stomach. It is about 25.4 cm (10 in) long, located behind the trachea, and collapses when not involved in swallowing. As you can see in Figure 15.4, the esophagus runs directly through the middle of the chest. To enter the stomach, the esophagus enters the diaphragm through an opening called the esophageal hiatus.

The upper esophageal sphincter, which is continuous with the inferior pharyngeal constrictor, controls the movement of food from the throat to the esophagus. The upper two-thirds of the esophagus consists of smooth and skeletal muscle fibers, which terminate in the lower third of the esophagus. Rhythmic waves of peristalsis, which begin in the upper esophagus, move the food bolus toward the stomach. Meanwhile, secretions from the esophageal mucosa lubricate the esophagus and food. Food passes from the esophagus into the lower esophageal sphincter (also called the gastroesophageal or cardiac sphincter). Remember that sphincters are muscles that surround the tube and act as valves, closing the tube when the sphincter contracts and opening it when it relaxes.

The stomach consists of four main parts: the cardia, fundus, body, and pylorus (see Figure 15.5). The cardia (or heart region) is the point where it joins the stomach and through which food passes into the stomach. Below the diaphragm, above and to the left of the cardia, is the dome-shaped fundus. Below the fundus is the body, the main part of the stomach. The funnel-shaped pylorus connects the stomach to the duodenum. The wide end of the funnel, the pyloric antrum, connects to the body of the stomach. gave
