Question

outline how oxygen is transported in the blood

Answer 1

oxygen is transported in blood through respiratory pigment called haemoglobin

Answer 2

$\huge{\textbf{\underline{Oxygen\;Transport\;In\;The\;Blood:-}}}$

There are two types of respiratory gases transported by blood:-

• Oxygen transport.
• Carbon dioxide transport.

★Oxygen transport by blood:-

Oxygen is a gas which is transported from alveoli to tissue through blood in 2 forms.

• Physical solution form:- Once the oxygen enters into blood, it combined with plasma to form dissolved oxygen and transported towards tissues. It accounts 3%.
• Oxyhaemoglobin form:-Haemoglobin is a respiratory pigment and capable of transport of four oxygen molecules. Haemoglobin contains four iron atoms and each one can accommodate one molecule of oxygen. Hence, one haemoglobin can accommodate 4 molecules of oxygen.
• When all the iron atoms of haemoglobin are accomodated by oxygen molecules. Then it is called Oxyhaemoglobin (saturated). This type of transport accounts 97%.
