Answer:
the four zones found in the ocean:
<em>the intertidal zone,</em> which is the area of the seashore that's underwater at high tide and above water level at low tide. this zone also has various kinds of organisms, like seastars, sea urchins and a lot of different species of coral !
<em>the pelagic zone,</em> which could be described as all of the sea other than the sea along the shoreline or the bottom of the ocean. it's funny because the word is actually derived from ancient greek, and the word pelagic literally means
"<em>open sea</em>" !
<em>the abyssal zone,</em> which can also be called the abyssopelagic zone (i don't even know how to say that-) describes the "depths" or the very bottom of the ocean, especially between about 10,000 and 20,000 feet (3,000 and 6,000 m) down !
and <em>the benthic zone, </em>which is made up of the "bottom", like the bottom of a lake or ocean floor, the sediment surface, and some sub surface layers. there's actually organisms living in that zone, too, and they're called benthos ! (i think that's really cute, lil benthos uwu)

Answer:
The cardiovascular system helps maintain homeostasis by continually supplying the central nervous system--the brain and spinal cord--with oxygen and glucose. Brain cells start dying after just one minute without oxygen. The brain is the control center for all of the body's homeostatic processes.
