Digestive system
Small intestine
Liver
Large intestine
Rectum
Pancreas
Mouth
Anus
Oesophagus
Stomach
The major role of the large intestine is to reabsorb water into the blood it also prepares undigested food to be egested in the form of faeces
Faeces stimulate the rectum to contract and are passed out via the anus
Food does not travel through the pancreas the pancreas produces digestive enzymes these enzymes pass into the small intestine
Hydrochloric acid in the stomach chemically digests food and kills bacteria
Faeces are temporarily stored in the rectum
Food is ingested through the mouth
Food is moved through the oesophagus by the wavelike movements of muscles this continues the physical digestion of food

The stomach is an expandable muscular bag that physically churns and temporarily stores food
The stomach releases juices that continue the chemical digestion of food
Food does not pass through the liver the liver produces bile which passes into the small intestine where it helps to digest fats
Food from the stomach enters the small intestine
Plasma transports dissolved substances around the body including oxygen glucose amino acids hormones and antibodies
Plasma carries heat around the body
It also carries the blood cells
Air enters the respitarory system
The throat
Plays its role in speech
It allows air to flow from the pharynx to the bronchus
The trachea divides into two bronchi one for each lung which allows air to flow in and out of the lungs
The lungs are two large spongy elastic organs located in the chest cavity
Narrow tubes in the lung
Ribcage
Diaphragm
Large sheet of muscle involved in inhalation and exhalation
Made up of 12 ribs
