- There are two kidneys in the urinary system with separate blood supplies.
- Which uses process of excretion and filtration.
- Each kidney there is a tube which lead to the bladder called the urethra.
- The ureter carries urine from the kidney to the bladder.
- The urine is conducted to the outside of the body to be excreted which travels down the vagina or penis.
- The fluid which surround cells are isotonic with the cytoplasm of the cells.
- The amount of water going into these cells are equal and remain the same size and shape.
- The kidney controls the composition of our blood.
- Blood circulating in to the tissues it will be concentrated causing hyper tonic tisse fluid or hypo tonic tissue fluid.
- Blood that circulates through our kidney excess water, excess salt can be removed and excreted at the urethra.
Urea contains nitrogen which is toxic to the body and cannot be stored.
Amino acids are normally use for growth but the extra amino acids is excess must be remove there toxic.
The blood circulated to the liver and the amino acids are converted around which is called urea.
The kidney will filter the urea from the blood.
The urea is drained and collected in the bladder.
- Salt and water is from sweat.
- Lungs excrete carbon dioxide which is a waste from respiration.
- The kidneys are responsible for the excretion of excess water (Amino Acids)
- The 3 organs of excretions are the lungs, kidneys and skin.
- The skin would give out water, salt and urea.
- The process of photosynthesis happens when Carbon dioxide and water which give off oxygen.
- Respiration is C6H12O6 +O2 which which gives off gas as a waste molecule.
- Photosynthesis is CO2 + H2O ----> C6H12O6 This happens due to the release of metabolic waste.
- Glucose molecule is broken down and energy is used to form ATP and get the waste of carbon dioxide and water given off.
- The waste process is called Excretion.
