Systemic arteries are the arteries (including the peripheral arteries), of the systemic circulation, which is the part of the cardiovascular system that carries oxygenated blood away from the heart, to the body, and returns deoxygenated blood back to the heart.

The Earth is a "closed system" which means that the amount of rocks, carbon, metals, nitrogen, water and oxygen on earth remains constant.
So it is essential that "biogeochemical cycles renew these materials" as they move through the Earth's subsystems.
<u>Explanation</u>:
The Earth's only source of extra-planetary energy is the Solar radiations received by Earth.
The biogeochemical cycles on the planet are responsible for processing the same old rocks, metals, carbon, nitrogen, oxygen, water, and other abiotic substances on Earth in order to naturally renew them and make them available for reuse.
No naturally occurring element on Earth is newly produced. It is only renewed through biogeochemical processes.
Environment plays an important role in living and the existence of life on earth. Earth is a home for many living species and we all are dependent on the environment for food, air, water, etc.
For the water currents flow from the equator to the poles the presence of the unequal solar heating and the coriolis force exerted by the rotation of the earth is due to action to take place as the place in the surface of the earth is heated by the sun similar the water are driven by the winds to the east i.e the anticlockwise and to the south in the clockwise direction and this creates pattern of the cold and warm waters being drifted from the top to poles to the equatorial areas.
<u>This up-down movement created by the rotation is a significant life in the balance of the temperatures on the earth. </u>
<u>And hence creates a pattern of the movement of the warm and the cold current in the ocean that heats and respectively warm and cools the temperature of the coastal and with there respective periods.</u>
