Question

Ureters:

a) Connect the kidneys to the liver
b) Act as tubal ducts leading from the hilus of the kidneys and drain into the urinary bladder
c) Are part of the respiratory system
d) Transport blood to the heart

Answer 1

Ureters connect the kidneys with the urinary bladder. They have smooth muscle walls that can contract to push urine through the ureter by peristalsis. The function of the urinary bladder is to collect and store urine from the kidneys before it is eliminated through urination.

Step-by-step explanation:

Ureters are tube-like structures that connect the kidneys with the urinary bladder. Each ureter arises at the renal pelvis of a kidney and travels down through the abdomen to the urinary bladder. The walls of the ureter contain smooth muscle that can contract to push urine through the ureter by peristalsis. The walls are lined with transitional epithelium that can expand and stretch.

The urinary bladder is a hollow, muscular organ that rests on the pelvic floor. It is also lined with transitional epithelium. The function of the bladder is to collect and store urine from the kidneys before the urine is eliminated through urination. Filling of the bladder triggers the autonomic nervous system to stimulate the detrusor muscle in the bladder wall to contract. This forces urine out of the bladder and into the urethra.
