Chapter 6
BREATHING AND EXCHANGE OF GASES
1. Distinguish between the following
a. IRV and ERV
Ans:-
IRV- inspiratory reserve volume
Additional volume of air that can be inspired forcibly after a normal inspiration
This averages 2500 - 3000 ml
ERV- Expiratory reserve volume
Additional volume of air that can be expaired forcibly after a normal expiration This average 1100- 1200ml
2. Carbon dioxide transport in the form of bicarbonate ion is picturizd below .Observe the diagram and identify the enzyme noted as A
Ans:- carbonic unhydrase
3. Carefully observe the given sigmoid curve
On the graph and answer the following questions
a. What does the graph indicates
b. What are the three factor affecting the sigmoid pattern of the graph
Ans:-
a. Oxygen dissociation curve
b. PO2 ,PCO2, Temperature and pH
4. Asthma and emphysema are the two disorder of the human respiratory system. Mention their causes and symptoms
Ans:-
Asthma:- Difficulty in breathing due to inflammation of bronchi and bronchiols
Emphysema:- Disease due to damage of alveolar walls . It is mainly by sigurt smoking
5. Pick out the wrong one and justify your answer
a. VC= ERV+IRV+TV
b. TLC= VC+RV
c. TV= 500 ml
d. ERV= 30000 ml
Ans:- ERV= 1000- 1
6. Identify the true statement from the statement given below and rewrite the False statements correctly
a. pneumonial sachronic disorder due to cigarette smoking
b. Carbon dioxide combine with haemoglobin to form carba-mino haemoglobin
c.Respiratory rhythm is maintained by the respiratory centre in the heart
d. Alveoli are the primary sets of exchange of gases
a. False
b . True
c. False
d. True
7. Observe the graph and answer the following questions
a. Identify the partial pressure of oxygen when 50 % of saturation Hb with oxygen
b. Mention the factors favorable for the formation of oxyheamoglobin in alveoli
Ans:-
a. 30 mm Hg
b.High partial pressure of oxygen low partial pressure of CO2 low H + concentrations low temperature
8. The graph given below is oxygen haemoglobin dissociation curve . Observe the curve and answer to the questions
a. Identify the PO2 where 90% of haemoglobin saturation occurs
b. Write any three factors favorable for the formation of oxyheamoglobin in alveoli
Ans:-
a. 60 mm Hg
b. High partial pressure of oxygen low partial pressure of CO2 ,low H+ concentration, low temperature
9. What do you meant by vital capacity
Ans:-
a. vital capacity is the maximum volume air a person can breathe in after a forced expiration
b. Regular exercise, avoid smoking, practice yoga
