a muscular sac; storage of liquid waste
a thin tube; filtration of waste from the blood
a network of blood vessels; waste elimination

Answer 1

Answer: A muscular sac; storage of liquid waste

Explanation:

The urinary bladder is a muscular sac in the pelvis, just above and behind the pubic bone. When empty, the bladder is about the size and shape of a pear. Urine is made in the kidneys and travels down two tubes called ureters to the bladder. The bladder stores urine, allowing urination to be infrequent and controlled.
