The 22 pages that link to Tracheal system, each with the reason it gives.

• GillsCompared with: Unlike gills, tracheal systems move air through branching tubes rather than exchanging gases across a water-facing surface.

• ArachnidRelated: Several arachnid lineages breathe through tracheae rather than book lungs.

• ChelicerataRelated: Some arachnids use tracheae instead of, or alongside, book lungs.

• Cutaneous respirationCompared with: It bypasses blood transport, unlike skin uptake followed by circulation.

• LungCompared with: Unlike lungs, it can transport air to tissues without first oxygenating blood.

• Gas exchangeBroader topic: Insects deliver oxygen to tissues without relying on blood as the main carrier.

• Respiratory systemCompared with: It transports air through branching tubes rather than relying on blood to carry most oxygen.

• Book lungRelated: Its distribution among arachnids provides a comparison for tracing respiratory evolution.

• Fish gillCompared with: Unlike gills, it can deliver air to tissues without transporting oxygen in blood.

• OpisthosomaRelated: Tracheae open through respiratory structures located on the opisthosoma in many arachnids.

• ArthropodaRelated: Insects and many other terrestrial arthropods use tracheae for gas exchange.

• MyriapodaRelated: Myriapods breathe through tracheae opening at the body surface.

• Insect respirationBroader topic: Its branches carry oxygen inward and carbon dioxide outward.

• Organ systemCompared with: It supplies tissues without relying on a lung-and-blood transport arrangement.

• Spider anatomyRelated: In species with tracheae, branching airways provide another route for gas exchange.

• CentipedeRelated: Centipedes breathe through spiracles connected to tracheae rather than lungs.

• MillipedeRelated: Millipedes breathe through spiracles connected to tracheae.

• Plastron respirationNarrower topic: Plastron oxygen enters the insect's tracheal system and reaches its tissues.

• External gillsCompared with: It carries gases through internal tubes instead of relying on exposed aquatic surfaces.

• OnychophoraRelated: Velvet worms breathe through tracheae that open through numerous small spiracles.

• RicinuleiRelated: Ricinuleans breathe through tracheae, a feature relevant to their arachnid anatomy.

• PauropodaRelated: Respiratory openings and tracheae are reduced or absent in many pauropods.
