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.

See Excretion and Improved sanitation
Insect
Insects (from Latin insectum) are hexapod invertebrates of the class Insecta.
Kidney (vertebrates)
The kidneys are a pair of organs of the excretory system in vertebrates, which maintain the balance of water and electrolytes in the body (osmoregulation), filter the blood, remove metabolic waste products, and, in many vertebrates, also produce hormones (in particular, renin) and maintain blood pressure.
See Excretion and Kidney (vertebrates)
Latex
Latex is an emulsion (stable dispersion) of polymer microparticles in water.
Lung
The lungs are the central organs of the respiratory system in humans and some other animals, including tetrapods, some snails and a small number of fish.
Malpighian tubule system
The Malpighian tubule system is a type of excretory and osmoregulatory system found in some insects, myriapods, arachnids and tardigrades.
See Excretion and Malpighian tubule system
Metabolic waste
Metabolic wastes or excrements 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. Excretion and metabolic waste are metabolism.
See Excretion and Metabolic waste
Metabolism
Metabolism (from μεταβολή metabolē, "change") is the set of life-sustaining chemical reactions in organisms.
Organism
An organism is defined in a medical dictionary as any living thing that functions as an individual.
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 which in this case is represented by body fluid) to keep the body fluids from becoming too diluted or concentrated.
See Excretion and Osmoregulation
Oxford University Press
Oxford University Press (OUP) is the publishing house of the University of Oxford.

Oxygen
Oxygen is a chemical element; it has symbol O and atomic number 8.
Pathology
Pathology is the study of disease and injury.
Photosynthesis
Photosynthesis is a system of biological processes by which photosynthetic organisms, such as most plants, algae, and cyanobacteria, convert light energy, typically from sunlight, into the chemical energy necessary to fuel their metabolism. Excretion and Photosynthesis are metabolism.

Resin
In polymer chemistry and materials science, a resin is a solid or highly viscous substance of plant or synthetic origin that is typically convertible into polymers.
Respiration (physiology)
In physiology, respiration is the movement of oxygen from the outside environment to the cells within tissues, and the removal of carbon dioxide in the opposite direction to the surrounding environment.
