probably bcuz they would be filtered by kidney & lost.
You have hemoglobin in red blood cells. They are 'inside' the capillaries.
Oxygen
False. Oxygen is primarily transported by red blood cells, specifically by hemoglobin molecules inside the red blood cells. Oxygen binds to hemoglobin in the lungs and is then transported to tissues throughout the body.
Red blood cell is an erythrocyte; it lacks nucleus and all the cell organelle to create a big surface area to carry hemoglobin molecule. Each erythrocyte contains approximately 200 million hemoglobin molecules and each molecule can carry up to four iron atom. Each iron atom can have a molecule of oxygen. Blood plasma is the fluid of the blood that contains plasma protein, nutrients, nitrogenous substances and electrolytes to name some. If the plasma was inside the erythrocyte, the cell will not have enough surface area to carry 1 billion molecules of oxygen. The erythrocyte will also not be able to withstand the nitrogenous waste because it is a by product of the metabolism of cells and can cause damage to the RBCs. For example uric acid can cause damage to the lining of the erythrocyte. There are many other reasons these are a couple of important reasons of why an erythrocyte doesn't have plasma in it.
Hemoglobin is the protein inside red blood cells that binds with oxygen. It consists of four protein subunits, each containing a heme group that can bind to oxygen molecules.
Blood is made of plasma and hemoglobin. Plasma is what hemoglobin and other nutrients, blood cells, etc are suspended in.
Inside the red blood cells
No, hemoglobin is not a plasma protein. Hemoglobin is a protein found in red blood cells that carries oxygen throughout the body. Plasma proteins are different types of proteins found in the liquid component of blood called plasma.
An Iron containing protein and is located on oxygencontaining molecule.
Yes, oxygen can travel bound to hemoglobin inside red blood cells and also as a gas dissolved in the plasma of blood. When oxygen is bound to hemoglobin, it forms oxyhemoglobin, which is the primary way oxygen is transported in the blood.
About 55% of our entire blood is blood plasma, it is a fluid and is the blood's liquid medium, it is straw-yellow in color.
When an oxygen molecule moves from inside an alveolus to the hemoglobin of a red blood cell, it crosses two plasma membranes. The first is the alveolar epithelium's plasma membrane, separating the alveolus from the capillary, and the second is the red blood cell's plasma membrane, where the oxygen binds to hemoglobin for transport. Plasma membranes are the outer boundary of cells that regulate the passage of substances in and out of the cell.

By lowering the blood plasma level, the red blood cells are concentrated.
It's when the red blood cells disintegrate, with the release of hemoglobin in the plasma.
Oxygen
No, Unlike oxygen, Carbon Dioxide is mostly disolved in the blood plasma only about 23% is disolved in hemoglobin
