What does blood do to the brain?

Blood supplies oxygen and glucose to the brain, which are essential for brain function.

- Oxygen is needed for the brain to produce energy. Without oxygen, the brain would quickly die.

- Glucose is a type of sugar that the brain uses for energy. Without glucose, the brain would not be able to function properly.

Blood also removes waste products from the brain. These waste products include carbon dioxide and other metabolic byproducts. If these waste products were allowed to accumulate, they would eventually damage the brain.

The blood-brain barrier is a specialized network of blood vessels that helps to protect the brain from harmful substances.

* The blood-brain barrier prevents potentially toxic substances from entering the brain.

* The blood-brain barrier also helps to maintain a stable environment for the brain. This is important for brain function.

Blood is essential for the health and function of the brain. Without blood, the brain would quickly die.
