The ocean is maintaining a constant salinity because:
11Alexandr11 [23.1K]
In mid-ocean ridge areas, ocean water is cycled through the crust because of the high heat flow in the area. Water in the rock is heated over the magmas, rising up and drawing in cold water from the sides. This process is occurring all over the world, and is the primary means for maintaining ocean salinity in a relatively constant range over the long term, as elements in the sea water when it is heated react with the rocks. There is so much water flow, cumulatively over the entire world, that this process basically buffers ocean chemistry.

Obviously large increases or decreases in salinity can and do occur in isolated basins that do not have free exchange with the open oceans.

Svetach [21]

Regulation of heart rate, blood pressure, and digestive functions are carried out by the <u>autonomic nervous system</u>

<u></u>

What is autonomic nervous system?

The peripheral nervous system's autonomic nervous system (ANS), originally known as the vegetative nervous system (VNS), provides smooth muscle and glands, which in turn affects how internal organs work. The autonomic nervous system is a control system that regulates body processes like the heart rate, digestion, respiratory rate, pupillary response, and urination mainly subconsciously. The fundamental mechanism in charge of the fight-or-flight response is this system.

Through the brainstem, the spinal cord, and the organs, integrated reflexes control the autonomic nervous system. Control of respiration, cardiac regulation (the cardiac control center), vasomotor activity (the vasomotor center), and other reflex acts including coughing, sneezing, swallowing, and vomiting are all examples of autonomic functions.
