Explanation:
We can possibly stop carbon flow into the atmospehere by
- Carbonisation process
- Storing carbons in the organic tisues (Green carbon)
- Blue carbon
- Artificial carbon sinks
Explanation:
Growing carbon in the atmosphere has wreaked havoc on the natural functioning of the ecosystem. This has altered the way of the natural flow of matter in the geo-biographic cycle. Following methods can be improvised to remove carbon from the atmosphere.
- Carbonisation process- Through this process atmospheric carbon dioxide can be stored in the natural rocks through the process of carbonisation, where elements react with atmospheric carbon under-stimulated condition to form carbonate rocks. Later these rocks are stored.
- Storing carbons in the organic tissues (Green carbon)- Plants and trees utilise atmospheric carbon to synthesise foods and make tissues. The proliferation of plants can remove carbon from the atmosphere and store it in their organic tissues. This carbon stored in the plant tissues is often called Green Carbon.
- Blue carbon- Marine plants and some organism utilise carbon to proliferate like phytoplankton’s and other. The atmospheric carbon us trapped in their body tissues. Later when they die, the body is decomposed and is recycled in the depths of the ocean. Hence atmospheric carbon is sequestered in the depth of the Ocean indirectly. These are often called Blue carbon.
- Artificial carbon sinks- Artificial sinks such as natural caves, underground caverns can be used to store carbon dioxide after separating it from the air. This carbon can be later utilised into the productive use for plants growth or any other purpose.
Can someone please help me with just this one question?
Answer:
Venous return (VR) is the flow of blood back to the heart.
Venous return to the right atrium is the most important factor determining cardiac output, provided both ventricles and the pulmonary circulation are normal.
Explanation:
Venous return refers to the flow of blood from the periphery back to the right atrium, and except for periods of a few seconds, it is equal to cardiac output.
Venous return is facilitated by a number of factors, including inspiration, increased total blood volume, increased venomotor tone, the cardiac suction effect, the presence of venous valves and the skeletal muscle pump.
Contraction of the skeletal muscles surrounding veins increases the pressure within the veins, pushing open the proximal valve and forcing blood toward the heart. For example, when calf muscles contract during exercise, blood is forced toward the heart, thus increasing venous return.
