To complete the statement above:
Ions are transported across membranes using channel-mediated facilitated diffusion; which requires <span>kinetic energy.
The channels can be opened by the requirements of the cell. Transmembrane proteins, called transporters, utilize the vitality of ATP to drive particles or little atoms through the layer against their focus angle.

The property is cohesion, I believe. It makes the molecules 'attract' to each other, and therefore, they move. However, adhesion makes water molecules stick to surfaces.
The mantle is a layer of hot compressed rock underneath the liquid outer core, which means that it is much hotter. It is heated by the inner core, and the magma rises upward towards the outer core. This eventually cools and sinks back down, only to be heated up again, and this goes on and on in a constant cycle.
Answer: No. You would not withdraw CSF if the needle is in the epidural space.
Explanation: There are 3 spaces that cover the spinal cord, which are epidural, subdural and subarachnoid spaces. The epidural space is the outer most space while the subarachnoid space is the inner most space. CSF flows from the brain where it is produced to the spinal cord. In the spinal cord it flows only in the subarachnoid space. Thus you would not be able to withdraw CSF if the needle is in the epidural space.
