What tube connects the kidney to the bladder and moves urine through peristalsis? A) The ureters B) The urethra C) The nephrons D) The renal arteries
Answer (1)
The correct answer to the question is A) The ureters .
In the human urinary system, the kidney is responsible for filtering blood and producing urine. Once urine is produced in the kidneys, it needs to be transported to the bladder, where it is stored until it is excreted from the body.
Ureters: These are two muscular tubes that connect each kidney to the urinary bladder. The primary function of the ureters is to carry urine from the kidneys to the bladder. This movement of urine is facilitated through a process called peristalsis. Peristalsis involves rhythmic contractions of the muscles in the walls of the ureters, which pushes the urine downward towards the bladder.
Urethra: This is a different part of the urinary system; it is a tube that carries urine from the bladder out of the body during urination.
Nephrons: These are the tiny filtering units located inside the kidneys. They are not tubes, but rather structures that filter blood to produce urine.
Renal arteries: These are blood vessels that supply blood to the kidneys and are not involved in transporting urine.
Understanding the roles of these different structures helps clarify how the urinary system functions as a whole to expel waste from the body effectively.
