New!!: Excretion and Defecation · See more »
Excretory system
The excretory system is a passive biological system that removes excess, unnecessary materials from the body fluids of an organism, so as to help maintain internal chemical homeostasis and prevent damage to the body.

Feces
Feces (or faeces) are the solid or semisolid remains of the food that could not be digested in the small intestine.
New!!: Excretion and Feces · See more »
Guanine
Guanine (or G, Gua) is one of the four main nucleobases found in the nucleic acids DNA and RNA, the others being adenine, cytosine, and thymine (uracil in RNA).

Guttation
Guttation is the exudation of drops of xylem sap on the tips or edges of leaves of some vascular plants, such as grasses.

Homeostasis is the tendency of organisms to auto-regulate and maintain their internal environment in a stable state.

Human waste
Human waste (or human excreta) is a waste type usually used to refer to byproducts of digestion, such as feces and urine.

Insect
Insects or Insecta (from Latin insectum) are hexapod invertebrates and the largest group within the arthropod phylum.

Malpighian tubule system
The Malpighian tubule system is a type of excretory and osmoregulatory system found in some insects, myriapods, arachnids, and tardigrades.
New!!: Excretion and Malpighian tubule system · See more »
Metabolic waste
Metabolic wastes or excretes are substances left over from metabolic processes (such as cellular respiration) which cannot be used by the organism (they are surplus or toxic), and must therefore be excreted.
New!!: Excretion and Metabolic waste · See more »
Organism
In biology, an organism (from Greek: ὀργανισμός, organismos) is any individual entity that exhibits the properties of life.
New!!: Excretion and Organism · See more »
Osmoregulation
Osmoregulation is the active regulation of the osmotic pressure of an organism's body fluids, detected by osmoreceptors, to maintain the homeostasis of the organism's water content; that is, it maintains the fluid balance and the concentration of electrolytes (salts in solution) to keep the fluids from becoming too diluted or concentrated.
