- - - - Your digestive tract is made up of a group of organs which include the following the the exact order
      - Mouth
      - Oesophagus
      - Stomach
      - Small Intestine
      - Large Intestine
      - Anus
    - - Although the Pancreas, Liver and Gall Bladder assisst with the digestive system, food doesnt pass through them.
  - - - Performed by oesophagus in which muscles contract to move food to the stomach
  - - - They speed up a reaction and are sometimes used in the digestive system to speed up the breaking down of food.
      - Pepsin is an enzyme found in the stomach
    - - The main point of the digestive system is to absorb nutrients for the body to use
- - - - Oxygenated and Deoxygenated Blood
  - - - Largest artery of heart
    - - Large vein which carries deoxygenated blood to the heart
    - - Carries blood from right ventricle of the heart to the lungs
    - - largest blood vessels. Carry blood away from heart. Very thick
    - - Connect Arteries to veins. One cell thick to allow substances to pass through.
    - - Carry blood back to the heart to be pumped else where. Veins contain one-way valves to avoid blood from going back
- - - - The fuction of the kidney is to filter the blood of waste products and take urine to the bladder
      - Nephrons filter the blood
    - - Skin uses sweat to release sweat
    - - Take waste products and turn them into less dangerous substances before being removed from the bosy
  - - - As the filterate flows through the renal tube, most of the water and nutrients are reabsorbed into the blood.
      - The concentrated fluid that remains is called urine
    - - Most filteration occurs in the glomerulus.
      - That's where water, salt, glucose, amino acids and urea are filtered from the body
