What's the difference between osmoconformers and osmoregulators? |
Osmoconformers: Animals that maintain internal conditions that are equal to the osmolarity (internal temperature) of their environment. Osmoregulators: Animals that maintain their osmolarity content (internal temperature), regardless of environmental conditions |

What is the excretory system in insects? How does it relate to the kidneys? |
The excretory system in insects (the Malpighian tubules) connects to the digestive system of the animals. The Malpighian tubule system in insects and the kidney carry out osmoregulation and the removal of nitrogenous wastes. |

What is the process of the bloods filtration? |
Blood enters the kidneys via the renal artery. The blood is filtered by specialised structures called nephrons which produce urine. The filtered blood exists the kidney via the renal vein. The urine is transported from the kidneys via the ureter, where it is stored by the bladder prior to excretion |

What is the difference between blood moving through the renal artery and blood moving through the renal vein? |
The blood in the renal vein (i.e. after the kidney) will have: - less urea (large amounts of urea is removed from via the nephrons to form urine) - less water and solutes/ions (amount removed will depend on the hydration status of the individual) - less glucose and oxegyn (not eliminated, but used by the kidney to generate energy and fuel metabolic reactions) - more carbon dioxide (produced by the kidneys as a by-product of metabolic reactions) |

What is ultrafiltration and how do the glomerulus and Bowman's capsule facilitate it? |
Ultrafiltration is the first of three processes by which metabolic wastes are separated from the blood and urine is formed. It is the nob |
