Who is credited with study of external respiration for the first time?
Cellular respiration is
The rate at which oxygen moves from the alveoli of our lungs into our blood
During respiration, exchange of gases takes place in
Utilization of $O _2$ by the cells to derive energy from nutrients for performing various activities and resultant release of $CO _2$ as by-produced is called
Descending aorta and pulmonary trunks are
The respiratory centers, which control inspiration and expiration, are located in?
Air is breathed through
In fever breathing rate
Which energy is consumed in breathing?
Breathing by ribs is more pronounced in
Amount of $O _2$ normally carried by 100 ml of pure blood, is
Cutaneous respiration takes place through
Which of the following features do all gas exchange have in common?
Full name of NADP is
In respiration, temperature
Pyruvic acid is converted into a compound before formation of oxaloacetic acid in the citric acid cycle, this compound is
Ribs move out in during
Brown coloured respiratory pigment is?
Respiratory membrane consists of.
When we breathe in air, nitrogen also goes inside along with oxygen. What is the fate of this nitrogen?
Which of the following statement(s) is (are) true about respiration?
(i) During inhalation, ribs move inward and diaphragm is raised.
(ii) In the alveoli, exchange of gases takes place i.e., oxygen from alveolar air diffuses into blood and carbon dioxide from blood into alveolar air.
(iii) Haemoglobin has greater affinity for carbon dioxide than oxygen.
(iv) Alveoli increase surface area for exchange of gases.
Breathing:
The inspiratory reserve volume + tidal volume + expiratory reserve volume is the same as
Abdominal breathing refers to
Pulmonary surfactant is
Rate of breathing in rabbit is
Which one of the following statements is not correct?
If a respiratory surface dries out, gas exchange will
Diffusion is insufficient to meet $...............$ requirements of multicellular organisms.

(G) 100mm Hg | (vii) Ethanol |
(H) Vocal cords | (viii) Branchial respiration |
State whether the following statements are true or false.
Because $NAD^+$ and FAD are critical coenzymes in cellular respiration, huge quantities must be synthesized in the cell to ensure there is no shortage.
