What's the difference between channel and river?

Channel


Definition:

  • (n.) The hollow bed where a stream of water runs or may run.
  • (n.) The deeper part of a river, harbor, strait, etc., where the main current flows, or which affords the best and safest passage for vessels.
  • (n.) A strait, or narrow sea, between two portions of lands; as, the British Channel.
  • (n.) That through which anything passes; means of passing, conveying, or transmitting; as, the news was conveyed to us by different channels.
  • (n.) A gutter; a groove, as in a fluted column.
  • (n.) Flat ledges of heavy plank bolted edgewise to the outside of a vessel, to increase the spread of the shrouds and carry them clear of the bulwarks.
  • (v. t.) To form a channel in; to cut or wear a channel or channels in; to groove.
  • (v. t.) To course through or over, as in a channel.

  • (15) The following model is suggested: exogenous ATP interacts with a membrane receptor in the presence of Ca2+, a cascade of events occurs which mobilizes intracellular calcium, thereby increasing the cytosolic free Ca2+ concentration which consequently opens the calcium-activated K+ channels, which then leads to a change in membrane potential.
