Welcome to another boring lesson. Today lesson is excretory system.
The first process is to have the urea,extra water and salts you don't need into organs called kidneys. Inside the kidneys there are something called nephrons. Nephrons takes your urea and stores it inside the nephron. The next step is in progress.
The urine travels to the tubes called ureters and flows to the bladder. The urine is emptied to the bladder and grows more to take in more urine. Sphincter is used to keep the bladder from leaking out the urine. The next step is in progress.
The brain would send signals to your bladder to release the urine. The bladder would squeeze and the sphincter would relax. The urine leaves the bladder to the tube called the urethra
