- Consider the diameter of a spherical object being measured with the help of a Vernier Callipers. Suppose its 10 Vernier Scale Divisions (V.S.D.) are equal to its 9 Main Scale Divisions (M.S.D.). The least count in the M.S. is 0.1 cm and the zero of V.S. is at -0.1 cm when the jaws of Vernier callipers are closed. If the main scale reading for the diameter is \(M = 5\) cm and the number of coinciding vernier division is 8, the measured diameter after zero error correction, is:

The Respiratory System
Human Respiratory System is a compound biological system of organs and tissues that helps in gaseous exchange. The system includes airways, lungs, and blood vessels. Its core function is to introduce oxygen and expel carbon dioxide from the body. The atmospheric air is continuously pumped in and out through a system of pipes which are called the conducting airways. There are a great number of muscles and blood vessels involved in the whole process of respiration.
Features of Human Respiratory System:
- The respiratory system is essential for inhalation of oxygen and transportation of the same to the different parts of the body where it is used for cellular respiration.
- The design of the lungs is created in a manner that helps in gaseous exchange in an efficient manner. The other parts of the respiratory system such as the nose, pharynx, larynx, trachea, and bronchi help in the process of bringing in oxygen to the lungs and taking carbon dioxide out of it.
- There is an arrangement of muscles such as the diaphragm and intercostal muscles that aid in the process of human respiration.
