Spiracles that connect tubes in the body belong to the respiratory system of insects. These structures allow air to enter into the insect's body and reach the tissues for gas exchange.
The bronchial tubes connect the trachea and the lungs. Air moves through these tubes into and out of the lungs.
Yes angiospermic plants have sieve tubes in their conducting tissues.
I believe they are called spiracles.
A persom can connect the two different types of Rotastak tubes by clicking the tubes together at the hinge. Rotastak tubes are common amongst hampster owners.
Capillaries are the smallest blood vessels in the body that connect arteries and veins. They are very narrow tubes that allow for the exchange of gases, nutrients, and waste products between blood and body tissues.
Fallopian tubes - the tubes that connect the uterus to the ovaries.
Bronchioles
The air openings on abdominal segments of terrestrial arthropods would be spiracles, which connect to the trachea and tracheoles to directly oxygenate tissues and remove waste gasses. The spiracles are regulated by muscles to open or close to reduce water loss.
Habitrail creates tubes that connect wire cages and tubes together
Capillaries are the tiny tubes that carry blood. These tubes connect arteries and veins.
Crickets have a system of tracheal tubes that allow for gas exchange. These tubes connect to openings on the cricket's body, called spiracles, allowing oxygen to diffuse directly into their tissues and carbon dioxide to be released. This adaptation helps crickets efficiently obtain oxygen from their environment.
