Study Notes

Excretory Systems

The process responsible for adding nonessential solutes and wastes from body fluids to the filtrate is reabsorption.
Filtration in excretory systems removes waste and excess substances from the blood.

Functions of Excretory Systems

Reabsorption is the process of reclaiming essential nutrients and water back into the bloodstream.
Secretion is the process of adding waste and excess substances to the filtrate.
Excretion is the removal of waste and excess substances from the body.

Types of Excretory Systems

Flatworms have a protonephridia excretory system.
Insects and other terrestrial arthropods have a Malpighian tubule excretory system.

Malpighian Tubules in Insects

The function of Malpighian tubules is to remove waste and excess substances from the hemolymph.
Insects conserve water by reabsorbing it from their excretory system.
The process of water reabsorption in insects is called antidiuresis.
Nitrogenous wastes are removed from hemolymph through the Malpighian tubules.

Protonephridia in Flatworms

The smallest branches of the protonephridia network are called flame bulbs.
Flame bulbs collect and remove waste and excess substances from the body fluids.
The function of the tubules in the excretory system of flatworms is to remove waste and excess substances from the body fluids.

Waste Matter

Insects produce uric acid as a fluid waste in excretory processes.
Insects conserve water by excreting uric acid, which reduces water loss.

Osmoregulation and Metabolic Waste Disposal

Transport epithelia rely on osmoregulation and metabolic waste disposal to maintain electrolyte and water balance.
