The digestive system consists of the oral cavity, oesophagus, stomach, liver, gall bladder, spleen, pancreas,intestines, appendix and the rectum. All these organs interlink in order to carry out an environment of homeostasis. Homeostasis is a state of equilibrium inside the body as stated in the Journal of Nursing Standards (Hendry C 2012 page (46-50)).A further consideration is that of legal and ethical concerns within practice.

The first part of the digestive system is the oral cavity and salivary glands. The function of the oral cavity is the ingestion of liquids, solids and the chewing of solids to break them down ready for the stomach. Salivary glands in the oral cavity secrets saliva in order to aid smoother digestion down the oesophagus

The stomach is mostly muscular organ and lies in the upper quadrant of the abdominal trunk. In relation to the Cardiovascular system , the abdominal aorta provides oxygenated blood to tissue and organs of the abdominal region. Mahadevan.V (2014) describes how the stomach releases mixtures of proteases and hydrochloric acids in order to begin digestion. Muscle contractions also known as Peristalsis help to the churn up the solid foods within the stomach.

The liver contains Bilirubin and Bile, bilirubin is the end element of breakdown of old red blood cells and bile helps to breakdown fatty acids in digestion. Wiley (2008) explains that the liver cleanses any Xenobiotics, which the liver has recognised are excreted in the form of urine or faeces along with bilirubin. Within the Liver is the hepatic portal system, there is a connection of veins which supply blood to the liver and this is how drugs metabolised in the

The Oxford Concise Medical Dictionary(2015) states that bile helps to emulsify fats and bind them together to make compounds for the continuation of peristalsis. The gallbladder isn 't a vital organ and can be removed. Causes for removal are gallstones which are detected via ultrasound and in surgery. Gallstones reduce bile and make it harder for the body to digest food increasing levels of toxicity causing a common symptom, jaundice.

The Spleen and Pancreas are located in the upper abdominal cavity. The Pancreas function is the release of glucagon, insulin, somatostatin and some digestive enzymes. Peate and Nair (2011) explains that the pancreas helps to regulate blood sugars and maintain metabolism. In digestion the function the pancreas plays is the of release enzymes which help the breakdown of harder molecule chains like lipids, starch and
