it plays a vital role in regulating blood flow, through a process called cerebral auto regulation,This is needed to maintain efficient cerebral blood flow of oxygen and other metabolites, and withdraw of metabolic wastes from the brain.

Explanation:
Red blood cells or erythrocytes are specialized cell that produce in bone marrow and have specific role such as carrying oxygen from lungs to deliver it to the various organs and carry out carbon dioxide.
In mammals these cells lack cell organelles such as nucleus and mitochondria, a major factor that determined its smaller size. The size of RBC are move through narrow vessels throughout a organism because of its specific size and shape that provide it space for hemoglobin and allow to be flexible and bend to move through narrow vessels.

Agriculture is an activity that requires a lot of fresh water.
- This is because agricultural crops need large amounts of water to grow and remain productive.
- In a situation of large-scale agricultural production, this need for water is even greater, causing producers to use large quantities of water that is necessary for the consumption of the population.
<h3>Give the detailed explanation?</h3>
In order to conserve fresh water and keep it at high quality levels to be used both in agriculture and for human consumption, it is necessary that agricultural producers allow the maintenance of riparian forests, use more biodegradable pesticides or with low impact on nature and pay attention to irrigation equipment to avoid waste.
In addition, many producers waste water and pollute it with an excess of pesticides and deforestation.
