What are the respiratory structures of a tarantula?
Tarantulas possess specialized respiratory structures known as book lungs and tracheae. Book lungs are stacked, leaf-like structures located in the abdomen that facilitate gas exchange, allowing oxygen to diffuse directly into the hemolymph. Additionally, tracheae are a network of tubes that deliver oxygen directly to the spider's tissues, enhancing respiratory efficiency. Together, these structures enable tarantulas to thrive in various environments by effectively managing their respiratory needs.
Which organ system in humans is most directly involved in transport of oxygen?
The respiratory system is most directly involved in the transport of oxygen in humans. Oxygen enters the body through the lungs during inhalation and is then transported by the circulatory system via red blood cells to tissues and organs where it is needed for cellular respiration.
What does the human respiratory system?
The respiratory system purifies and oxygenates the blood, so that there is constant supply of oxygen to the tissues.
Where does the breathing begin?
The respiratory tract consists of organs and tissues such as the nose, pharynx, bronchi, trachea and alveoli. The respiratory tract starts at the nose.
How do insects respire?
Insect respiratory system uses a system of internal tubes and sacs through which gases either diffuse or are actively pumped, delivering oxygen directly to tissues that need it via their trachea.
Why is the respiratory system needed to keep all the tissues in your body alive?

Do wasps have lungs?
No, insects do not have lungs, they have a system of small holes in their exoskeleton which allows air entry into a system of narrow tubes from which it can diffuse directly into their living tissues.
What is lymphatic tissues?
The nasopharyngeal lymphatic tissue is the mucosal lymphoid tissue of the respiratory tract.
