Red blood cells (RBCs), or erythrocytes, have a biconcave disc shape that increases their surface area for efficient gas exchange. They contain hemoglobin, a protein that binds oxygen in the lungs and releases it in tissues, and they lack a nucleus and organelles, allowing more space for hemoglobin. RBCs are flexible, enabling them to navigate through narrow capillaries. Their primary function is to transport oxygen from the lungs to the body and return carbon dioxide for exhalation.

How do you read red blood cells?
A CBC (Complete Blood Count) or FBC (Full Blood Count) are used to read red blood cells as well as the other two types, white blood cells, and platelets. Blood counts are the most commonly used blood tests in medicine practice because of the accuracy to provide a overview of a patients general health. The test is conducted by drawing blood into a test tube, using an anticoagulant to stop it from clotting and then transported to a laboratory for testing.
Where can one learn more about the blood cell?
There are quite a few types of "blood cells". Luckily sites like Wikipedia has information on all of them. You can read about the Red blood cells, White blood cells and even the Platelets. Alternatives to Wikipedia are the Franklin Institute's website and Fun Science.
Do all cells work exactly the same?
No there are white blood cells, red blood cells, (and I'm not sure if there are others) and they all have different purposes and jobs. white blood cells protect red blood cells from getting infected. if a red blood cell is infected then the white blood cells get rid of it.

What cells are in the bloodstream?
The cells in the bloodstream include red blood cells, white blood cells, and platelets. Red blood cells carry oxygen to tissues, white blood cells help fight infections, and platelets aid in blood clotting.
From where is the oxygen taken in from the blood?
Oxygen bonds to the iron in your hemoglobin. Hemoglobin is carried by your red blood cells. If I read your question correctly, You want to know where it leaves the blood; and the answer to that is in the capillaries. From there it diffuses into the cells, into the mitochondria, wherein it disappears (it's turned into water).
How do you read a microhematocrit tube?
Microhematocrit tubes are read according to PCV (Packed Cell Volume). After centrifuging the tube, you will need a PCV card reader to determine the amount of packed red blood cells within the sample of blood. The PCV is determined by aligning the top of the clay plug (just as it reaches the layer of red blood cells) on the zero line and then gently "rolling" the tube up the chart until the intersecting middle line is aligned where the packed red cells and Buffy coat meet. Read across the chart and you should have a percentage of red blood cells to record as a PCV.
