Answer:
ureters
Explanation:
The ureters are two tubes that drain urine from the kidneys to the bladder. Each ureter is a muscular tube that drains into the bladder. Smooth muscle contractions in the walls of the ureters, over time, send the urine in small spurts into the bladder, the organ where urine is stored before it can be eliminated.

If you are referring to inflation of the universe caused by the Big Bang, and the subsequent "ripples", then those ripples are the leftover, background radiation from the event. If you are referring to ripples in space-time, then it still could have multiple meanings.

Answer: Haemocoels
Explanation:
In the open circulatory system found in arthropods and mollusks, the heart pumps blood into a blood vessel which branches and opens in an internal structure called Haemocoels.
The haemocoel is a highly functional part because it allows
- organs and tissues to be bathed in blood,
- for exchange of materials to occur between the body cells and the blood.
- blood to eventually flows back to the heart.
