Trachea consists of C-shaped cartilaginous rings that support the walls of the trachea and prevent it from collapsing during inspiration.

Respiratory centre is located in medulla region.

Yeast undergoes anaerobic respiration to produce ethanol and $C{O}_2$ .

The type of respiration in insects and fish is tracheal respiration and branchial respiration respectively.

ATP is a biologically useful energy produced during respiration.

The partial pressure of $O_2$ in alveolar air is approximately 104 mm Hg.

Vocal cords are present inside the larynx.
