The Siphonaptera has most complex excretory system, don't be fooled by it's size, it's a very complex organism!
Organ systems are most complex and fragile starting with the atoms. The most complex organ systems is the organism. In between are the molecules, cell, tissue, organ, and organ system.
organ system
the excretory organ of cockroach is the malpighain tubules. it is found at the junction of the midgut and hind gut and are about 150 in numbers, they are fine yellow in color and branched in thread present in bundles. they lie freely in the hacmolymph.
Liver is the most important part of excretory organ as it secrete some enzymes helps the system to breakdown the macromolecules into smaller components easily absorb-able to blood Answered by PASHA
Cells form tissues which form organs which form body systems
The group of organ systems organized from most complex to least complex typically starts with the nervous system, then the circulatory system, followed by the respiratory, digestive, excretory, endocrine, and finally the integumentary system.

Organ systems are most complex and fragile starting with the atoms. The most complex organ systems is the organism. In between are the molecules, cell, tissue, organ, and organ system.
cells < tissue < organs <organ systems
organ system

the brain
atoms and molecules --> cell --> tissue --> organ --> organ system --> organism
The structures of the human body in order from least to most complex are cell, tissue, organ, and organ system.

The levels of organization from most complex to least complex are: organism, organ system, organ, tissue, and cell. Organisms are made up of organ systems, which are made up of organs, which are made up of tissues, and tissues consist of cells.
