● Excretory unit of Earthworm : Nephridia
● Excretory unit of Amoeba : Amoeba has a contractile vacuole as an excretory organ that gathers the excretory wastes delivered inside the cell.
● Nephron functioning : It actually gives a structure to the kidney and regulates all types of activities inside kidneys. Each nephron starts from Bowman's capsule which continues behind a narrow tubule.
● Function of Glomerulus : It helps in the filtration of Excretory Wastes from the blood.
● Function of Bowman's capsule : It continues behind a narrow tubule which ultimately opens into a duct leading to the ureter.

Hey there !

☺☺☺☺☺☺☺☺☺☺

functions of nephrons :

Each kidney is made up of excritry units called nephrons. The Nephron has a cup shape upper end called Bowman's capsule. Bowman's capsule a bundle of blood capaliries called glomerulus. The lower end of the Bowman's capsule is tube shape and it is called Tubule. One end of the tubule is connected to the Bowman's capsule and the other end is connected to the urine collecting duct of the kidney.
One end of the glomerulus is attached to the rennal artery which brings the dirty blood containing the uria waste into it. The other end of the glomerulus comes out as a blood caplliries, surrounds the tubule of the nephron and finally joins a rennal vein .
