Red Blood Cells (erythrocytes) contain haemoglobin.
The protein contained within blood cells that allows them to carry oxygen is called Haemoglobin. The haemoglobin molecule can carry up to four oxygen molecules which are exchanged for carbon dioxide molecules released as a waste product from cell metabolism.
Blood is ~55% plasma and ~45% red blood cells (erythrocytes). These cells contain millions of molecules of the protein hemoglobin each of which can bind up to 4 oxygen molecules.
it transports oxygen (there are 4 atoms of iron in one haemoglobin, which means that it can transport 4 molecules of oxygen..)
IT is transported in the blood attached to the haemoglobin molecules in red blood cells.
Capillaries in your lungs provide oxygen to the haemoglobin molecules of red blood cells.
By the Haemoglobin in our red blood cells.
Red blood cells because that is what carries oxygen throughout the body
The basic structure of red blood cells is that they have a bi-concave shape to increase surface area, and lack a nucleus so that more haemoglobin can be packed in.

Haemoglobin is found the red blood cell (RBC), not in the platelet.
