Where do supporters of the outside-in model say earth’s water originated from? inside of volcanoes inside the atmosphere bonded to meteorites that hit the earth bonded to minerals in earth's mantle

Bonded to meteorites that hit the Earth

Explanation:

Some hypothesis refering to origin of water on Earth sugges, that a very long time ago as asolar system was young, some asteroids may have landed also carrying frozen water. The meteorites would then turn to provide liquid water, these meteorites were protoplanets from the outer asteroid belt that is in the solar system.

However this still is not the mainstream theory.

these muscles maintain the blood pressure in the vessels. the smooth muscles are innervated by nerves of the autonomic nervous system. when the muscles contract, they cause vasoconstriction of the vessels and increase blood pressure. when the muscles relax, they enable vasodilation of the   blood vessels hence reduce blood pressure.
