Questions: 1 point Oxygen is distributed directly to neurons by other neurons astrocytes ependymal cells red blood cells

The answer is the last one: red blood cells.

Explanation for each option:

• Other neurons: Neurons are responsible for transmitting signals in the nervous system, but they do not directly distribute oxygen. They rely on the blood supply for oxygen.

• Astrocytes: These are a type of glial cell in the brain that support neurons and help maintain the blood-brain barrier, but they do not directly distribute oxygen to neurons.

• Ependymal cells: These cells line the ventricles of the brain and the central canal of the spinal cord, playing a role in the production and circulation of cerebrospinal fluid, but they do not distribute oxygen.

• Red blood cells: These cells are responsible for carrying oxygen from the lungs to the rest of the body, including neurons, via the bloodstream. They are the primary means by which oxygen is distributed to neurons.

In summary, red blood cells are the cells that directly distribute oxygen to neurons.
