Chapter 25.4, Problem 25.11P

Interpretation Introduction

(a)

Interpretation:

The role of the process of diffusion in the transport of gases through the body needs to be explained.

Concept Introduction:

The gasses are transported from the lungs to the whole body and this transfer of gases in the lungs takes place by the process of diffusion. The gases in the lungs diffuse from their region of high pressure to their region of low pressure and are either taken throughout the body or exhale out depending upon the gas.

Interpretation Introduction

(b)

Interpretation:

The role of carbaminohemoglobin in the transport of gases throughout the body needs to be explained.

Concept Introduction:

Other than diffusion, there are other methods for the transport of gases. The carbaminohemoglobin is one of the methods of transport for the carbon dioxide gas where the carbon dioxide binds with hemoglobin to form carbaminohemoglobin as per the following equation:

  

Interpretation Introduction

(c)

Interpretation:

The role of alveoli in the transfer of gases throughout the body needs to be explained.

Concept Introduction:

Alveoli are the air sacs in the lungs which basically increases the surface area capacity of the lungs and these alveoli are the sites of the gases transfer from the atmosphere to the blood in the body.

Interpretation Introduction

(d)

Interpretation:

The role of carbonic anhydrase in the transfer of gases throughout the body needs to be explained.

Concept Introduction:

The transfer of carbon dioxide also takes place by means of carbonic anhydrase. The carbonic anhydrase converts to carbonic acid
