The diagram shows two cells from the lining of the trachea. Name the cells P and R.

Trachea is the part of respiratory system that is present between the larynx and bronchi. It is also called windpipe. The wall of trachea contains three types of cells, the goblet cells, the cilia cells and the basal cells. In the given figure, the cells showing the cup shaped depression are the goblet cells (labelled as R cells) The cells labelled as P cell are the cilia cells that beat the cilia and remove the mucus from respiratory tract.

The diagram shows two cells from the lining of the trachea. Name the structures S, T, U and W.

The diagram shows two cells from the lining of the trachea. Why cell P contains many of the structures labelled as T.

In the given figure of the cells in the lining of the trachea, the cells labelled as R cells are called the goblet cells and the cells labelled as P cells are the cilia cells that beat the cilia and remove the mucus from the respiratory tract. The structures labelled as S, T, U and W are: S -Cilia T- Mitochondria U- Golgi body W- Nucleus Mitochondria are abundant in the cilia cell of the trachea because it produces the energy in form of ATP, which is required for the ciliary beating. These cells push back the mucus towards the throat and prevent its entry into the lungs.

The diagram shows two cells from the lining of the trachea. Explain the role of structure U in cell R.

In the given figure of the cells in the lining of the trachea, the cells labelled as R cells are called the goblet cells and the cells labelled as P cells are the cilia cells that beat the cilia and remove the mucus from the respiratory tract. The structures labelled as S, T, U and W are: S -Cilia T- Mitochondria U- Golgi body W- Nucleus In the goblet cells, there are abundant Golgi bodies. The main function of the Golgi body is to sort, modify and do the packaging of macromolecules that are secreted by the cells. The goblet cells secrete mucus that traps the dust particles, bacteria, pathogen etc.,

The diagram shows two cells from the lining of the trachea. The magnification is diagram is × 750. Write the formula that you will use to calculate the actual length of cell P.

In the given Image the cell P is the ciliated cell and Cell R is th e goblet c ell of the lining of the trachea. The length of cell P on page is 80mm. The magnification is 750 times. Thus, the length of the cell will be = T h e l e n g t h o f c e l l o n p a g e M a g n i f i c a t i o n o f t h e c e l l

The diagram shows two cells from the lining of the trachea. The magnification is a diagram is × 750. Use a formula to calculate the actual length of cell P.

In the given Image the cell P is the ciliated cell and Cell R is the goblet cell of the lining of the trachea. The length of cell P on page is 80mm. The magnification is 750 times. Thus, the length of cell will be = 80 ÷ 750 = 0.107 mm

The diagram shows two cells from the lining of the trachea. The magnification is a diagram is × 750. Use a formula to calculate the actual length of cell P. Give your answer to the nearest micrometre.

In the given Image the cell P is the ciliated cell and Cell R is the goblet cell of the lining of the trachea. The length of cell P on page is 80mm. The magnification is 750 times. Thus, the length of cell will be = 80 ÷ 750 = 0.107 mm= 107μm

The diagram shows two cells from the lining of the trachea. Describe the role of cell P and Cell R in the gas exchange system.

In the given figure, the cells showing the cup-shaped depression are the goblet cells (labelled as R cells). The role of these cells in the respiratory tract is to secrete mucus that traps the foreign particles like dust, bacteria, viruses, pollen, etc., and prevent their entry into the alveoli or the gas exchange surface The cells labelled as P cells are the ciliated cells that beat back and forth to move the mucus towards the throat. These cells thus remove the mucus from the respiratory tract.
