becoz the plasma is not supposed to.
yes they are
only about 1.5% of the oxygen transported is carried in the dissolved form
By the haemoglobin in the red blood cells and by plasma
By the haemoglobin in the red blood cells and by plasma
Gas is carried mostly by the plasma in the blood. The plasma contains dissolved gases such as oxygen and carbon dioxide, which are transported to different parts of the body. Oxygen is transported from the lungs to the tissues, while carbon dioxide is carried from the tissues back to the lungs for elimination.
Oxygen, carbon dioxide, and food
Oxygen
The plasma, or liquid part of the blood, is primary responsible for transporting nutrients, hormones, and wastes. Oxygen, in contrast, is carried by the red blood cells.
Oxygen can travel dissolved in the plasma, but mostly it binds to a specific molecule - hemoglobin - found in red blood cells.
A small portion is carried in the blood plasma and the remainder is transported by combining with hemoglobin.
When oxygen enters the bloodstream through the lungs it generally binds to red blood cells (more specifically the hemoglobin within red blood cells), which are carried along within the plasma. While some unbound oxygen may become diffused inside the plasma itself it is not the primary or intended mean of oxygen transport throughout the body. In short, plasma doesn't carry oxygen, but instead carries the cells that carry oxygen.
