Section through human abdomen

Illustration of a section through the human abdomen describing the process of continous ambulatory peritoneal dialysis, the infusion of dialysis fluid from a plastic bag directly into the peritoneal cavity via a plastic catheter. The purpose of both peritoneal dialysis and haemodialysis (performed on a kidney machine) are to remove waste products from body fluids of a person whose kidneys function insufficiently. In both cases the principles of dialysis are identical (see detail at top right): waste solutes in blood diffuse across a semipermeable membrane (in this case the peritoneal membrane) towards the lower solute concentrations of the dialysis fluid

Stars in the Tarantula Nebula

Tarantula nebula. Hubble Space Telescope (HST) image of filaments of gas in the Tarantula Nebula (NGC 2070). The bright star cluster Hodge 301 is seen at lower right. The gaseous filaments were formed when massive stars in Hodge 301 exploded as supernovae. The material the stars eject in these explosions is causing shock waves which compress the gas into these filaments. The compressed gas may eventually form into stars itself, continuing the cycle of stellar life and death. The Tarantula Nebula lies in a satellite galaxy of our Milky Way, the Large Magellanic Cloud, around 160, 000 light years away
