Question

blood constituents and transport of respiratory
gases is most accurate ?

transport CO₂
(b) RBCs transport oxygen whereas plasma
transports only CO₂
(c) RBCs as well as WBCs transport both oxygen and CO₂
(d) RBCs as well as plasma transport both oxygen and CO₂

Answer 1

Answer:

b can be the Wright answer

Answer 2

The correct statement about the blood constituents and the transport of respiratory  gases is (d) RBCs as well as plasma transport both oxygen and CO₂

• Once the oxygen is diffused across alveoli, it then enters the bloodstream and is transported to the tissues where it's unloaded.
• During this process, CO2 is diffused out of the blood and into the alveoli, that is to be expelled from the body.
• Carbon dioxide can be transported through the blood through three methods. it is dissolved within the blood, it is bound to the plasma proteins or the hemoglobin, or it is converted into bicarbonate.
• The bulk of CO2 is transported as a part of the bicarbonate system and CO2 diffuses into the red blood cells.
