Taenidia is the vital component of which system in human body?

  • Respiratory system

  • Digestive system

  • Excretory system

  • Reproductive system


A.

Respiratory system

Taenidia is the vital component respiratory system in human body. It is also known as intima. It is the inner spiral cuticular thickening of the tracheae. It prevents the tracheae from collapsing.

According to Boyle's law, the product of pressure and volume is a constant. Hence,

  • if volume of lungs is increased, the pressure decreases disproportionately

  • if volume of lungs is increased, the pressure remains the same

  • if volume of lungs is increased, the pressure decreases proportionately

  • if volume of lungs is increased, the pressure also increases proportionately


80.

  • zero

  • one

  • less than one

  • more than one
