Detailed explanation-1: -Unlike most other eukaryotic cells, mature red blood cells don’t have nuclei. When they enter the bloodstream for the first time, they eject their nuclei and organelles, so they can carry more hemoglobin, and thus, more oxygen. Each red blood cell has a life span of around 100–120 days.
Detailed explanation-2: -RBC have no nucleus. The only function of RBCs is to carry oxygen, so they want to maximise the space for haemoglobin (which binds to oxygen) inside the cell.
Detailed explanation-3: -The red blood cells without nuclei, called reticulocytes, subsequently lose all other cellular organelles such as their mitochondria, Golgi apparatus and endoplasmic reticulum.
Detailed explanation-4: -A type of blood cell that is made in the bone marrow and found in the blood. Red blood cells contain a protein called hemoglobin, which carries oxygen from the lungs to all parts of the body.
