Does plasma transport oxygen?
Is Plasma Responsible for Transporting Oxygen in the Blood?
Click For Summary
Discussion Overview
The discussion revolves around the role of plasma in transporting oxygen in the blood, exploring the contributions of plasma versus hemoglobin in this process. It touches on biological and physiological concepts related to blood composition and gas transport.
Discussion Character
- Conceptual clarification, Technical explanation
Main Points Raised
- Some participants note that a small amount of oxygen is dissolved in plasma, but the majority is carried by hemoglobin.
- One participant specifies that approximately 98% of oxygen is bound to hemoglobin while about 2% is dissolved in plasma.
- Another participant describes the composition of blood, stating that plasma is the major component and includes various substances, including dissolved respiratory gases like oxygen and carbon dioxide, suggesting that plasma does indeed transport oxygen.
Areas of Agreement / Disagreement
Participants generally agree that plasma contains some dissolved oxygen, but there is no consensus on the significance of this transport compared to hemoglobin. Multiple viewpoints regarding the extent of plasma's role remain present.
Contextual Notes
The discussion does not resolve the implications of the percentages mentioned or the physiological significance of oxygen transport by plasma versus hemoglobin.

A small bit of dissolved oxygen is present in the plasma, but it's dwarfed by the amount in hemoglobin.

% 98 amount in hemoglobin , % 2 in the plasma (dissolved)

Blood constitutes of plasma,leucocytes,platelets,and erythrocytes.Plasma covers the major component of the blood(roughly 55%).It consists of water ,ions,plasma proteins,hormones and dissolved substances(glucose and vitamins,waste products,and respiratory gases such as oxygen and carbon dioxide).So it is clear that plasma transports oxygen.
