The digestive system is a group of organs that work together to convert food into energy that the cells in the body can use. The digestion starts off in the mouth when you chew your food and the teeth breaks it down into smaller pieces. This food would end up in the small intestine and as it passes through the gastrointestinal tract, the food mixes with many digestive juices which breaks down the larger food that wasn’t broken from the mouth. Once all these food has been broken down to the appropriate size, the body can absorb the food through the small intestine to the blood stream which then delivers the nutrients collected into the rest of the body. The wasted products would then pass through the large intestine and out the body.

All the organs that work with the digestive system is the salivary gland, esophagus, liver, stomach, gallbladder, pancreas, small intestine and the large intestine. The salivary gland is known to secrete saliva which contains an enzyme amylase which breaks down carbohydrates into starch. The esophagus which is known as a food pipe, transfers all the food from the mouth to the stomach. The liver would secrete bile to emulsify fat and in the stomach chemical breakdown happens with acid and enzymes. Both chemical and mechanical digestion. The cells in the pancreas secrete digestive enzymes. Lastly in the small intestine, all the nutrients and energy would be absorbed and transferred into the blood stream and all the indigestible waste would go to the large intestine and would be made into stool.

The respiratory system is made up of the airway, lungs and the muscles of respiration. As you breathe in, your body collects oxygen from the mouth or nose depending where you’re breathing from. Once your body takes in the oxygen, it passes the windpipe which is known as the trachea. This filters the air so no harmful bacteria within the air can enter the body deeper. The oxygen then goes to the bronchi where the oxygen will be separated into 2 tubes which will go into each lungs. The bronchi tubes are known to have tiny hairs lined along which tramps the germs and dust that has come in with the oxygen. Once these unwanted substances has been trapped, your body will trap it with the mucus so you can get rid of it by sneezing or spitting. Carbon dioxide will be breathed out from the lungs once the oxygen enters the blood. Aerobic respiration is when glucose reacts with the oxygen in order to release energy. Red blood cells carries oxygen around the body and every cell needs oxygen in order to stay alive. Oxygen is needed to burn fatty acids and sugar in cells to produce energy.

The cardiovascular system is made up of the heart, lungs, veins, arteries and vessels. This system is responsible for the flow of blood, oxygen, hormones and nutrients around the body. The heart has 4 chambers which pumps blood through the arteries and veins. Blood vessels, veins and arteries transport blood from the heart and delivers oxygen to cells and returns the deoxygenated blood back to the heart. The oxygen is divided by quality, arteries are known to carry good quality oxygen-rich blood from the heart to the body whereas the veins are known to carry oxygen-poor blood back to the heart.
