The type of respiration which does NOT involve blood is the
Correct answer: B. Tracheal respiration in cockroach
- A. Pulmonary respiration in frogs
- B. Tracheal respiration in cockroach
- C. Cutaneous respiration in earthworms
- D. Bucco-pharyngeal respiration in frogs
Explanation
Tracheal respiration in cockroaches involves a system of air-filled tubes called tracheae that deliver oxygen directly to cells, bypassing the need for blood to transport gases. This is unlike pulmonary, cutaneous, and bucco-pharyngeal respiration, which all involve the circulatory system to circulate oxygen and carbon dioxide throughout the body. In pulmonary respiration, lungs are involved; in cutaneous respiration, gases diffuse through the skin; and in bucco-pharyngeal respiration, the lining of the mouth is used for gas exchange, all of which rely on blood as a transport medium.

About Human Respiratory System
The human respiratory system conducts air to the alveoli, where oxygen and carbon dioxide exchange occurs across thin respiratory surfaces. Questions cover the nasal passage, trachea, bronchi, lungs, diaphragm and intercostal muscles, ventilation mechanics and gas transport, while distinguishing breathing and gaseous exchange from cellular respiration.
