Haemoglobin is the oxygen carrying pigment found inside red blood cells haemoglobin binds with oxygen at high levels (in the lungs) and forms oxyhaemoglobin haemoglobin combines with oxygen.
Red blood cells are derived from stem cells in red bone marrow new red blood cell production, also called erythropoiesis , is triggered by low levels of oxygen in the blood low oxygen levels can occur for various reasons including blood loss, presence in high altitude, exercise, bone marrow damage, and low hemoglobin levels.
The life of a red blood cell in my latest interview i am following up the journey and life of a red blood cell a red blood cell is a round red cell which can only be seen microscopically, it delivers the body vital nutrients such as oxygen. Erythrocytes, commonly known as red blood cells, neutrophils are a type of white blood cell that ingests and destroys invading microorganisms they have large amounts of lysosomes, which contain enzymes that kill ingested cells biology cells cell division, diversity and organisation. About 85% of the co 2 produced by respiration diffuses into the red blood cells and forms carbonic acid under the control of carbonic anhydrase the hco 3 − diffuses out of the red blood cell into the plasma this leaves a shortage of negatively charged ions inside the red blood cells to compensate for this, chloride ions move from the plasma into the red blood cells.
Myeloid stem cells give rise to red blood cells, platelets, and some types of white blood cells, while lymphoid stem cells give rise to the types of white blood cells classified as lymphocytes image modified from hematopoietic system of bone marrow , by openstax college, anatomy & physiology ( cc by 30 .

Red blood cells: are small and very numerous - they are 55 million per mm3 of blood are shaped like a biconcave disc contain cytoplasm rich in haemoglobin - this is the protein that gives red. Red blood cells (erythrocytes): these cells determine blood type and are the most abundant cell type in the blood red blood cells have what is known as a biconcave shape red blood cells have what is known as a biconcave shape.
Blood cells all blood cells begin as unspecialised stem cells in the bone marrow , which then differentiate through various paths to become specialised cells, such as erythrocytes and neutrophils. Red blood cell: red blood cell, cellular component of blood that carries oxygen from the lungs to the tissues and gives vertebrates’ blood its characteristic color.
