The digestive system absorbs the minerals and nutrients from the foods that have been eaten. The break down of food beings in the mouth, where the

The digestive system is made up of all different organs which starts at the mouth and finishes at the anus but on the way involves all other organs; these organs help to break down and absorb the food.

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.

The digestive and excretory systems help the body with the wonderful task of food. The digestive system is composed of the stomach, mouth, liver, pancreas, and the large and small intestine. It digests food and provides the

Food is digested by being broken down, by a variety of enzymes, into useful nutrients, which are transported around the body to places where they can be of use, and into waste products, which are excreted from the body. The digestive system is made up of a number of organs, oesophagus, stomach, liver, pancreas, gallbladder, and small and large intestines, these are then separated into the digestive tract and the digestive organs. The digestive tract is, essentially, a single continuous tube that begins at the mouth and ends at the anus, in a fully grown adult it is approximately seven metres long. Food travels through the digestive tract and the digestive organs produce the enzymes and chemicals that are responsible for

Your brain is a very powerful thing. It controls everything about you. Your thoughts, your actions, your emotions. Everything we see, feel and do are actions of our brain. Our brains are the most complex things in this world. They start to develop at just 4 weeks in the womb. They form more connections then stars in the sky. In the Pbs series “The Secret life of the Brain” they divide your brains life into 5 parts, the babies brain, the child’s brain, the teenage brain, the adult brain and the aging brain.

The brain contains millions of nerve cells and about a hundred structures that control different parts of our bodies. The brain controls our movement, language comprehension, sight, hearing, it determines our personality, as well as behavior. The complexities of the brain often bring about problems that lead to cognitive and physical decline. As we

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.

The brain is the part of the central nervous system located in the skull. It controls the thoughts and physical actions of a human being. The brain is a soft, shiny, mushroom shaped structure. The brain of an average adult weighs about 3 lb. The brain's surface is covered with many bright red arteries and bluish veins.

Your digestive system is amazing—it is comprised of a complex network of organs that work together to provide you with the nutrients from the food you eat, while eliminating harmful substances from your body. Unfortunately, the importance of digestive health is greatly underappreciated.

The brain is the most important part of the body, it controls everything we do. It is one of the most complex organs of the body. It has many parts, including these main bits: The cortex is the outer layer of the brain and it controls thinking and movement. The brain stem/spinal cord is between the spine and the rest of the brain and the controls our sleep and breathing. The cerebellum is in the middle and back of the brain and controls balance and coordination. There are also several lobes which are important to the brain as well. The frontal lobe is responsible for problem solving and judgement and the temporal lobe is responsible for memory and hearing. The parietal lobe is responsible for processing sensory information from

Did you know that the brain is broken up into different sections? It is composed of three different parts: the cerebrum, cerebellum, and the brainstem. The cerebrum is the largest part of the brain and it composed of a right and left hemisphere. It controls higher functions such as interpreting touch, vision and hearing. However, did you know that the cerebrum also controls speech, reasoning, emotions, learning, and fine control of movement. The funny thing is that every person is different, and that we are learn new stuff everyday.

It has organs that have different roles to help the digestive system do its job. One of the organs, names is the esophagus. It is a muscular tube around the throat area, it is connected to the stomach, its job is to carry food down it.The stomach is located on the left side of the abdominal cavity. Its job is to break down the food it uses acid to help it when doing its job. Next to the stomach is the small intestine. The small intestine is a long, thin tube that is located in just inferior in the stomach and takes up most of the space in the abdominal cavity. Its job is to absorb nutrients and materials next is the gall bladder it is located under the liver and its job is to store and recycle excess bile from the small intestine so that it can be reused for the digestion of subsequent meals. After the gallbladder is the large intestine. It is a long thick tube that is located under the stomach and wraps around the borders of the small intestine it job is to absorbed water. Finally, there is the pancreas it a large gland located just inferior and posterior to the stomach. And its job is to further break down food after it has left the

All animals and humans have a digestive system. The purpose of a digestive system is to digest and absorb. Digestion is the process by which food is broken down into small molecules, these small molecules are then absorbed into the body. The digestive system has two main parts, the digestive tract and accessory organs. According to Cliffs notes (https://www.cliffsnotes.com/study-guides/anatomy-and-physiology/the-digestive-system/function-of-the-digestive-system) the digestive system has seven main processes. Ingestion; Propulsion; Secretion; Mechanical digestion; Chemical digestion; Absorption; Defection. All seven of processes are important in order for the digestive system to work.

The digestive system is when the body does to break down food. Firstly, it enters the mouth and is broken down by the teeth of the animal and saliva. Then it travels along the oesophagus to the stomach. Then in the stomach for further breaking down, it is broken down by hydrochloric acid and enzymes. The acid breaks down bacteria and the food material into smaller molecules. Once this is complete it then moves onto the small intestine. Enzymes are secreted from the pancreas into here and bile from the liver which emulsifies fats. Nutrients from the food are absorbed into the bloodstream. Then it moves onto the large intestines where water is absorbed to produce faeces waste. Then it is moved to the rectum to be released from the anus. This is the basic digestive process of a monogastric animal, other animals are more complex and different processes happen.
