What is RBC in biology?

red blood cell, also called erythrocyte, cellular component of blood, millions of which in the circulation of vertebrates give the blood its characteristic colour and carry oxygen from the lungs to the tissues. The mature human red blood cell is small, round, and biconcave; it appears dumbbell-shaped in profile.

What does RBC mean in medical?

Also called erythrocyte and red blood cell. Enlarge. Blood cells. Blood contains many types of cells: white blood cells (monocytes, lymphocytes, neutrophils, eosinophils, basophils, and macrophages), red blood cells (erythrocytes), and platelets.

How is RBC formed?

Red blood cells are formed in the red bone marrow of bones. Stem cells in the red bone marrow are called hemocytoblasts. They give rise to all of the formed elements in blood. If a stem cell commits to becoming a cell called a proerythroblast, it will develop into a new red blood cell.

What is your RBC level?

The normal RBC range for men is 4.7 to 6.1 million cells per microliter (mcL). The normal RBC range for women who aren’t pregnant is 4.2 to 5.4 million mcL. The normal RBC range for children is 4.0 to 5.5 million mcL.

What are normal RBC levels?

A normal range in adults is generally considered to be 4.35 to 5.65 million red blood cells per microliter (mcL) of blood for men and 3.92 to 5.13 million red blood cells per mcL of blood for women. In children, the threshold for high red blood cell count varies with age and sex.

What is the full form of HB?

The Full form of HB is Hemoglobin. HB is the protein molecule in red blood cells that carries oxygen from the lungs to the body’s tissues and returns carbon dioxide from the tissues back to the lungs. Hemoglobin is made up of four protein molecules called globulin chains that are connected together.
