Excretory System Development
The excretory system refers to the continuous production of wastes that cannot be
reused or even toxic in the metabolic process of animals. At the same time, excessive
intake of water, salt and some toxic substances are taken into the body when the
animals ingest food, and these substances must be continuously excreted.
The endogenous substances, excess substances and substances not required by the
body are transported to the excretory organs through the blood circulation and are
excreted from the physiological process in vitro, which is called excretion. This
process is mainly done by the way the kidneys form urine. The excretory system also
has a relatively stable function of regulating water, salt metabolism, acid-base
balance, and maintaining the body environment while discharging urine. Therefore,
the development of the excretory system is very important for the body's steady
state. If the excretory system is not developed properly, it will cause some serious
diseases.
