2. Nephron
2.1. "The nephron is the tiny filtering structure in your kidneys" (David Mangusan Jr. 2008)
2.1.1. Your nephrons help remove water, wastes and other substances.
2.2. Nephrons are composed of two structures: the glomerulus and the renal tubule.
2.2.1. The glomerulus is a tiny blood vessel or capillary.
2.2.1.1. Filtering of your blood occurs in the glomerulus. The glomerulus preform like a selectively permeable membrane, keeping proteins and cells in your bloodstream while allowing wastes to pass through.
2.2.1.1.1. After the wastes pass the Glomerulus they're sent through the renal tube..
2.3. What does a nephron look like?
2.4. Parts of a nephron..
3. Homeostasis and kidneys...
3.1. Your kidneys hold molecules (sodium, phosphorus, potassium). The kidneys release them to the body when the it needs them.
3.1.1. Your kidneys balance and regulate chemicals for the body. Kidneys are used in the process of homeostasis.
4. Tissues that make up the kidney..
4.1. The renal tubules and the nephron are made up of epithelial tissues.
4.1.1. Epithelial tissue is used in the kidneys to allow excretion. The kidneys are busy structures and their jobs involve moving plenty of molecules around. The epithelial tissue helps get certain molecules in/out of the body.
4.1.1.1. The epithelial tissue is used to reabsorb materials from the urine.
4.2. A thin layer of fibrous connective tissue holds the kidney together.
5. What is coming and going through the kidneys?
5.1. The renal tubes use protein channels to get materials in/out. These protein channels are a form of facilitated transport. These channels only allow some molecules through, in the kidneys case, sodium, phosphate, or potassium may be trying to get through.
5.1.1. "Opening and closing of these channels changes the relative concentrations on opposing sides of the membrane" (Boundless. 14 Nov. 2014.)
5.1.1.1. Osmosis causes the smaller molecules/wastes to be separated from the blood and proteins. It pushes the waste/needed molecules through the carriers, and then either to the blood stream or to be filtered through the glomerulus. The concentrations on either side will determine which substances will be able to go through the channels.
5.1.1.1.1. For example: if the blood stream wanted salt from the kidney it would have a lower concentration of salt. Because a balance is needed the salt would be transported out through the channel to the blood stream.
5.1.1.1.2. The kidneys are used to filter out molecules, and wastes. So osmosis is very important. It allows the kidneys to filter out the wastes from the needed molecules. The wastes will be excreted and the needed molecules will not.

7. THE URINARY SYSTEM'S OVERALL FUNCTION
7.1. The urinary system removes wastes from the body.
7.2. The kidneys (an organ of the urinary system)balance and regulate chemicals (salts, phosphorus) that go into or come out of the rest of the body. Also, they regulate the amount of water in your body.
7.2.1. Fun fact: If your body has no functioning kidneys you will die within a few days.
7.3. How kidneys regulate blood pH..
7.3.1. If blood is acidic, H+ is excreted
7.3.2. If blood is basic, H+ is not released.
