The Digestive Systems Of Animals

Digestion begins when food is eaten by your dog. Once swallowed, it begins its journey down the oesophagus into the stomach. This is where it will be broken down by hydrochloric acid into a liquid. The liquid will then pass into the small intestine. This is where the main part of the digestion takes place. Assisted by the liver and pancreas the nutrients

The cardiovascular system consists of the heart, blood and blood vessels. The cardiovascular system is the major transport of materials to and from the cells. Blood is carried from the heart around the body via the arteries and the blood is then carried back to the heart via the veins. The

The digestive system of a pig is classified as monogastric or non-ruminant, which is having a stomach with only a single compartment, like humans. In addition, the digestive tract of the pig has five main parts, including the mouth, esophagus, stomach, and small and large intestines. Furthermore, the mechanical breakdown of the food begins upon the entrance of the mouth in the digestive tract. Basically, the food is grinded into smaller pieces by its teeth. Next, saliva is produced in the mouth, acting to moisten the small food particles, along with an enzyme that starts the digestion of the starch. Then, the food is pushed towards the esophagus with the help of the tongue. Primarily, the esophagus carries the food from the mouth to the stomach, being a tube, which is carried out with the help of a series of muscle contractions that push the food towards the stomach. Subsequently, after the first of the contractions, swallowing, has taken place, the cardiac valve, located at the end of the esophagus, prevents food from passing from the stomach back to the esophagus. Likewise, the stomach comes next in the digestive tract; it serves as a reaction chamber, adding chemicals to the food. Also, hydrochloric acid and enzymes help break down food into small particles of carbohydrates, protein, and fats. Additionally, some particles are absorbed into the bloodstream, from the stomach, while others cannot be absorbed by the stomach, being passed to the small intestine through the pyloric valve. Moreover, the small intestine aids

Our mouth, esophagus, stomach, pancreas, liver, gallbladder, large intestine, small intestine, rectum, and anus come together to form the digestive system which breaks down our food into simpler molecules. The food enters through the mouth, travels down the esophagus, breaks down in the stomach, pancreas, liver, and gallbladder and then moves through the intestines down to the rectum and anus. A pig’s digestive system is no different than a human’s. A foregut, midgut, hindgut, and a digestive gland form the digestive system of a crayfish. The foregut contains the stomach (partially breaks the food down), the

“Explain the physiology of two named body systems in relation to energy metabolism in your body”

The digestive system is a group of organs working together to convert food into energy and basic nutrients to feed the whole body. To achieve the goal of providing energy and nutrients to the body, six processes take place in the digestive system.

Trace and discuss the complete movement of a bolus of food entering and exiting the human via the digestive system.

The digestive system of the horse consists of a simple stomach, small intestines, cecum, large and small colons, rectum and anus. The horse 's stomach is comparatively small for its size. The stomach of an average horse has a holding capacity of about two gallons. This may be the reason horses eat small but frequent meals. From the stomach food moves to the small intestine, which is the main site of digestion. The small intestine empties into the cecum. The cecum; along with the large colon; make up the large intestine. Digestion in the large intestine occurs by action of bacteria and protozoa. (arg.gov.sk.ca)

All 5 species have a working-normal digestive system. Although the frog, earthworm, fetal pig, and human all have an intestine. The starfish is not much alike. It has a stomach that pushes through the mouth of the starfish and uses the digestive juices to breakdown and eat food.

Their medium digestive tracts are very capable for digesting meat with proteins and fats, and still long enough to cater for vegetable substance.

The digestive system is the process that involves the mouth, esophagus, stomach, small intestine, large intestine and rectum. For the body to function, the body`s cells needs energy and that energy will come from the food we eat. All the food we eat contains nutrients, carbohydrates, glucose, lipids, protein and many more other substances. The only way the body can absorb and convert these nutrients into energy to our cells is through breaking down the large molecules into smaller pieces and moist by the action of enzymes.

Main components of the circulatory system are the heart, blood vessels, and blood. The heart helps pump blood throughout the body, the functions are to transport oxygen as well as blood from the lungs and to other tissues in the body.

(P4) Explain the physiology of two named body systems in relation to energy metabolism in the body

The digestive system is very important in digesting food and breaking it down so it can be digested easily. The digestive system turns food into energy. Throughout the process there are nutrients which are absorbed. There are many things that contributed to the digestive system such as the mouth which produces saliva which helps to break down food and nutrients such as carbohydrates with the help of an enzyme called amylase. The major food groups which are called macro nutrients include carbohydrates, proteins and fats. All of these nutrients play an important role in the body. There are also many micro-nutrients which include vitamins and minerals which provide the body with health and well-being. The digestive system is made up of the mouth, which includes the teeth (the teeth are used to cut and grind food into smaller pieces, they contain blood vessels and nerves), tongue (the tongue is a muscle that has a rough surface including the taste buds), salvia glands (they produce salvia which moistens the food to make is easier to digest), the pharynx (this helps the food travel to the stomach, the pharynx also plays an important role in the respiratory system. It also contains 2 different flaps to separate the 2 functions), esophagus (this connects the pharynx to the stomach and transports chewed food to the stomach), stomach (this is a muscle that is

Despite the species or facet of the industry an operation is built to cater too, one of the easiest ways to improve the efficiency of livestock is through feed and nutrient management. Feed efficiency for livestock only becomes more important as farmers are responsible for feeding a growing population. However, in order to do that is important that a manager or owner understands the digestive system of that species and factors that can aid in this system ability to absorb the maximum amount of nutrients. This paper will be focused around different aspects of the ruminant digestive tract, and more specifically two of the smaller ruminant species being sheep and goats. I will explain in detail the 6 essential nutrients and why they are crucial to have in a feed ration, what occurs in each compartment of the stomach, including breakdown of feed, nutrient absorption, and also parasites that can become an issue in
