Question

How are the alveoli designed to maximise the exchange of gases?
10) What would be the consequences of a deficiency of haemoglobin in our bodies?
who is it necessary?​

Answer 1

Explanation:

so alveoli are ballon like structures wich are rich in blood vessels abd capillaries so easy gas exchange takes place .

haemoglobin is a pigment which gives the red colour to the blood cells. it is the pigment which carries oxygen in rbc throughout the body

if we had deficiency of haemoglobin then we would have very less energy since there is not enough transfer of oxygen throughout the body

Answer 2

Answer:

Alveoli is the place where there is exchange of gases (carbon dioxide is given out and oxygen is taken in). Alveoli increase the surface area for the exchange of gases and are richly supplied with blood vessels.
