    Study Notes

    The Nephron

    • The nephron is the functional unit of filtration and collection in the kidney.
    • The first part of the nephron is called the glomerulus, which receives branches from the renal artery.

    Glomerulus

    • The glomerulus is a loopy structure where blood from the renal artery is filtered to produce filtrate.
    • The glomerulus is the main site for filtration, where blood is pushed out as fluid, and waste or excess ions are removed.
    • The glomerulus leaks out fluid, which is caught in a capsule called Bowman's Capsule.

    Bowman's Capsule

    • Bowman's Capsule is a ball-like structure that collects the filtrate or fluid that comes out of the glomerulus.
    • The inside of Bowman's Capsule is an open space called Bowman's Space, where the filtrate is collected.

    Filtration Process

    • The filtration process occurs because of high pressure in the glomerulus, which causes fluid to leak out.
    • The fluid leaks out through the fenestrated endothelial cells, which have holes that allow small molecules like sodium, amino acids, and glucose to pass through.
    • A basement membrane sits between the endothelial cells and the tubule, which is semi-permeable and allows small molecules to pass through while preventing larger proteins from leaking into Bowman's Space.

    Endothelial Cells

    • Endothelial cells line the vessels and are eukaryotic cells with a nucleus and organelles.
    • The endothelial cells are fenestrated, meaning they have holes that allow small molecules to pass through.

    Basement Membrane

    • The basement membrane is a semi-permeable membrane that sits between the endothelial cells and the tubule.
    • It allows small molecules to pass through while preventing larger proteins from leaking into Bowman's Space.

    Podocytes

    • Podocytes are a type of epithelial cell that hugs the vessel and helps maintain the connection between the endothelial cells and the tubule.
    • Podocytes are a class of epithelial cells that have leg-like projections and play a crucial role in the filtration process.
