- Two bean-shaped kidneys, two ureters, one urine bladder, and one urethra are the parts of the human excretory system.
- The human excretory system's primary organ is the kidney.
- The kidneys are a pair of organs that are found at the level of the liver on either side of the spine.
- The renal cortex, which is the outside layer, the renal medulla, which is the inner layer, and the renal pelvis, which transports urine from the kidney to the ureter, are the three sections.
- The nephron is the functional component of a kidney.
- As a continuation of the renal pelvis, one ureter emerges from each kidney. The ureter is a muscular tube that connects the kidneys to the bladder and transports urine.
- The ureters, one for each kidney, deliver urine to the bladder.
- It's a sac-like structure lined with smooth muscle that stores pee until micturition expels it (urination).
- The urethra is a tube that emerges from the bladder and excretes urine by micturition.
- Females have a shorter urethra than males do.
- The urethra is a passageway for sperm and urine in males.
- A urethral sphincter protects the entrance.
