Abdomen
The abdomen (less formally called the belly, stomach, tummy or midriff) constitutes the part of the body between the thorax (chest) and pelvis, in humans and in other vertebrates.

Arachnid
Arachnids are a class (Arachnida) of joint-legged invertebrate animals (arthropods), in the subphylum Chelicerata.

Carbon dioxide
Carbon dioxide (chemical formula) is a colorless gas with a density about 60% higher than that of dry air.

Carboniferous
The Carboniferous is a geologic period and system that spans 60 million years from the end of the Devonian Period million years ago (Mya), to the beginning of the Permian Period, Mya.

Cellular respiration
Cellular respiration is a set of metabolic reactions and processes that take place in the cells of organisms to convert biochemical energy from nutrients into adenosine triphosphate (ATP), and then release waste products.

Central nervous system
The central nervous system (CNS) is the part of the nervous system consisting of the brain and spinal cord.

Dioxygen in biological reactions
Dioxygen plays an important role in the energy metabolism of living organisms.

Discontinuous gas exchange
Discontinuous gas-exchange cycles (DGC), also called discontinuous ventilation or discontinuous ventilatory cycles, follow one of several patterns of arthropod gas exchange that have been documented primarily in insects; they occur when the insect is at rest.

Ectoderm
Ectoderm is one of the three primary germ layers in the very early embryo.

Exoskeleton
An exoskeleton (from Greek έξω, éxō "outer" and σκελετός, skeletós "skeleton") is the external skeleton that supports and protects an animal's body, in contrast to the internal skeleton (endoskeleton) of, for example, a human.

Gas
Gas is one of the four fundamental states of matter (the others being solid, liquid, and plasma).
New!!: Respiratory system of insects and Gas · See more »
Gas exchange
Gas exchange is the physical process by which gases move passively by diffusion across a surface.
New!!: Respiratory system of insects and Gas exchange · See more »
Hemolymph
Hemolymph, or haemolymph, is a fluid, analogous to the blood in vertebrates, that circulates in the interior of the arthropod body remaining in direct contact with the animal's tissues.

Insect
Insects or Insecta (from Latin insectum) are hexapod invertebrates and the largest group within the arthropod phylum.
New!!: Respiratory system of insects and Insect · See more »
Invagination
In developmental biology, invagination is a mechanism that takes place during gastrulation.
New!!: Respiratory system of insects and Invagination · See more »
Meganeura
Meganeura is a genus of extinct insects from the Carboniferous period (approximately 300 million years ago), which resembled and are related to the present-day dragonflies.

Molecular diffusion
Molecular diffusion, often simply called diffusion, is the thermal motion of all (liquid or gas) particles at temperatures above absolute zero.
New!!: Respiratory system of insects and Molecular diffusion · See more »
Muscle contraction
Muscle contraction is the activation of tension-generating sites within muscle fibers.
New!!: Respiratory system of insects and Muscle contraction · See more »
Oxygen
Oxygen is a chemical element with symbol O and atomic number 8.
New!!: Respiratory system of insects and Oxygen · See more »
Spiracle
Spiracles are openings on the surface of some animals, which usually lead to respiratory systems.
New!!: Respiratory system of insects and Spiracle · See more »
Taenidia
Taenidia (singular: taenidium) are circumferential thickenings of the cuticle inside a trachea or tracheole in an insect's respiratory system.

Tissue (biology)
In biology, tissue is a cellular organizational level between cells and a complete organ.
New!!: Respiratory system of insects and Tissue (biology) · See more »
Trachea
The trachea, colloquially called the windpipe, is a cartilaginous tube that connects the pharynx and larynx to the lungs, allowing the passage of air, and so is present in almost all air-breathing animals with lungs.
