Chapter 46, Problem 1TYK

Summary Introduction

Introduction:

Respiratory medium is a medium or environmental source, in which animal’s exchange gases with their surroundings. It is a source of oxygen (O₂) for living beings.

Expert Solution & Answer

Answer to Problem 1TYK

Correct answer:

Air and water, describe the respiratory medium.

Explanation of Solution

Justification for the correct answer:

Option (e) states that air and water describe the respiratory medium. This is a true statement as gas exchange involves intake of O₂ and release of CO₂ (carbon dioxide). This gas exchange occurs in the air for terrestrial animals or in water for aquatic animals, or both in air and water for amphibians and fishes. Hence, the option (e) is correct.

Justification for the incorrect answers:

Option (a) states that liver of an amphibian, in which the rate of diffusion is high describes the respiratory medium. This is a wrong statement because liver is neither a respiratory organ nor does an exchange of gases take place in it. So, it is an incorrect option.

Option (b) states that neurons in the human brain, where CO₂ moves from neurons to the blood. This is not correct because the level of CO₂ controls breathing and regulates pulmonary ventilation of a body. Therefore, it does not act as a respiratory medium but helps in maintaining the concentration gradient of O₂ and CO₂ across the respiratory system. So, it is an incorrect option.

Option (c) states that O₂ in the blood of humans serves as a medium of respiration. It is incorrect because O₂ is a gas that is exchanged in a medium and serves as an important component of respiration not as a medium. So, it is an incorrect option.

Option (d) states that epithelial cells of a fish that are in contact with air. This is a wrong statement because epithelial cells of a fish are not an environmental source of O₂ but act as a respiratory surface driving the exchange of gases across the medium. So, it is an incorrect option.

Hence, options, (a), (b), (c), and (d) are incorrect.

Conclusion

Therefore, it can be concluded that water and air are sources of O₂ and act as a sink, in which CO₂ is released, thus act as a respiratory medium.

Affected individuals show spots of abnormal skin pigmentation and non-cancerous tumors that can interfere with the nervous system and cause blindness.
