Breathing and E...

Inner surface of bronchi, bronchioles and fallopian tubes is lined by.

Each $$100$$ml of human arterial blood carries 'P' ml of $$O_2$$ and 'Q' ml of $$CO_2$$ whereas each $$100$$ml of venous blood carries 'R' ml of $$O_2$$ and 'S' ml of $$CO_2$$. Choose the correct values of P, Q, R and S.

Choose the right sequential phenomena during passage of $$O_2$$ from blood to tissues.
P. Absorption of $$CO_2$$ by blood
Q. Reaction of $$CO_2$$ with water forming $$H_2CO_3$$ inside RBCs and then $$H^+$$ and $$HCO_3$$ ions.
R. Reaction of $$CO_2$$ with water forming $$H_2CO_3$$ inside plasma followed by conversion into $$H^+$$ and $$HCO_3$$ ions.
S. Combination of $$H^+$$ with haeme part of $$HbO_2$$ to release $$O_2$$.
T. Combination of $$HCO_3$$ with haeme part of $$HbO_2$$ to form reduced haemoglobin and release of $$O_2$$.

What is the total oxygen carrying capacity of blood?

$$CO_2$$ is carried in blood by haemoglobin in the form of _______.

Carbon dioxide is carried in blood.

Match the columns and find the correct combination.

Which structure of lungs is directly involved in $$O_2/ CO_2$$ exchange between air and blood capillaries?

What percentage of $$CO_2$$ is transported as bicarbonate $$(HCO_3)$$?

What would happen if human blood becomes acidic?
