Red blood cells are found in the animal kingdom, even though they do not contain a nucleus or organelles.
Red blood cells and white blood cells belong to the circulatory system. White cells are also found in the lymphatic system and are important in the immune response. Red blood cells are also found in the spleen. The spleen breaks down old red blood cells and recycles them and acts as a reservoir for red blood cells when excess bleeding occurs.
According to the AB0 blood group system there are four different kinds of blood groups: A, B, AB or 0 (null). Blood group A If you belong to the blood group A, you have A antigens on the surface of your red blood cells and B antibodies in your blood plasma. Blood group B If you belong to the blood group B, you have B antigens on the surface of your red blood cells and A antibodies in your blood plasma. Blood group AB If you belong to the blood group AB, you have both A and B antigens on the surface of your red blood cells and no A or B antibodies at all in your blood plasma. Blood group 0 If you belong to the blood group 0 (null), you have neither A or B antigens on the surface of your red blood cells but you have both A and B antibodies in your blood plasma.
They are both different cells
poikilocytosis
The circulation system in the body contains hemoglobin, more specifically the blood.
Red blood cells, despite their lack of a nucleus, is considered to be a eukaryote. This is mainly because the stem cell it originated from had a nucleus, but it disappeared in order to make room to carry oxygen and carbon dioxide. Also, a red blood cell is still part of the kingdom animalia, not monera which is what prokaryotes belong to.
Red blood cells contain hemoglobin. These cells are also known as erythrocytes.
Red blood cells because that is what carries oxygen throughout the body

Red blood cells contain hemoglobin, but white blood cells do not
As the name says, red blood cells are found in the blood. If there is blood there, there is red blood cells.
