Respiratory System BIOLOGY - Respiratory System

Draw neat labelled outline sketch to show the respiratory system of humans.

What happens in lungs of people suffering from emphysema?

What effect does altitude have on breathing?

Explain the role of blood in respiration.

Describe the path of air from nostrils to lungs.

The exchange of air takes place between capillaries and ............. . (alveoli/bronchi/trachea)

The trachea has cartilaginous rings to prevent their collapsing. These rings are ............. . (complete /half/ incomplete)

Adam's Apple is ............. . (pharynx / larynx/ glottis)

The trachea is guarded by a cartilaginous flap which closes windpipe at the time of swallowing food. It is called ............. . (epiglottis / glottis / larynx)

Oxygen loosely joins with ............. . (RBCs / WBCs/plasma)

Look at the given diagram and answer the following questions.

(i) Label the parts (1) to (4).
(ii) Give the aim of the experiment for which this set-up is used.
(iii) Name the human respiratory organs symbolized by (1), (2) and (3) in the given set-up.

The diagram given below represents an experimental setup for demonstrating certain aspects of the air breathed in/out. The two valves C and D help to regulate the direction of the flow of air.

Answer the following questions:
(i) There are mistakes at two places in the diagram. Redraw the diagram correctly to eliminate these mistakes.
(ii) What is the aim of the experiment?
(iii) Name the liquid contained in the test tube A and the liquid in test tube B.
(iv) what would be the observations after performing the experiment?

Given below are sets of five terms each. Rewrite the terms in correct order in a logical sequence beginning with the term that is underlined.
Larynx, Lungs, Diaphragm, Nasal cavity, Pharynx.

Given below are sets of five terms each. Rewrite the terms in correct order in a logical sequence beginning with the term that is underlined.
Bronchus, Alveoli, Trachea, Larynx, Bronchioles

Given below are sets of five terms each. Rewrite the terms in correct order in a logical sequence beginning with the term that is underlined.
Nasal cavity, Pharynx, Nose, Lungs, Trachea.

Give the technical terms for the following:
A disease which occurs in smokers.

Give the technical terms for the following:
The volume of air normally inspired or expired in one breath.

Tidal volume: Vital capacity+ IRV+ ERV.

ERV is the maximum capacity of lungs for inhaling air.

Tidal volume is equal to vital capacity of the lungs.

Expiration is an active process.

Pharynx is the common passage for food and air.
