Because erythrocytes carry oxygen (and carbon dioxide too, but C02 attaches to the protein portion of hemoglobin, not the iron portion). Our cells need to get rid of carbon dioxide and use oxygen to survive. Leukocytes are more focused on protecting the body from foreign invaders, like bacteria and parasites. They also clean up debris from wounds. But although this is important, it isn't as necessary to our immediate survival as getting rid of C02 and getting oxygen into our cells. Look at it this way -- we can survive about 3 minutes without oxygen. Without any of our white blood cells, we can probably survive a couple of hours before dying from infection.
Yes, there are typically many more erythrocytes (red blood cells) than leukocytes (white blood cells) in the blood. The ratio of red blood cells to white blood cells is about 600:1. This difference in numbers reflects the different functions and roles of these two types of blood cells in the body.
Erythrocytes are larger than leukocytes. Erythrocytes have no nucleus while leukocytes have nucleus. Leukocytes remove and/ or destroys things that are considered "abnormal" in the body while erythrocytes carry oxygen to all body cells. Leukocytes are large round cells that do not contain hemoglobin while erythrocytes contain hemoglobin, are shaped as biconcave disks that bend, flex travel through narrow blood vessels and have a large surface to volume ratio. Erythrocytes and leukocytes are both classified as formed elements (lower layer). They both are main components of the body are necessary for the body to function properly.
Erythrocytes make up about 45% of the blood Plasma makes up the other 55% and a Buffy coat consisting of leukocytes and platelets makes up less than 1%
There are 5 leukocytes in the human body. They include: Eisinophil, basophil, neutrophil, lymphocyte and monocyte. The leukocytes that end in "phil" are more granular than the cytes.
In relation to the human body, it is a common misconception that blood is blue; all blood is red. The blue appearance is due to the connective tissues of the blood vessels. Blood cells can be either erythrocytes, which are red, or leukocytes, which are white. When blood is oxygenated it is a much brighter red than de-oxygenated blood.

White blood cells are larger than red blood cells. White blood cells, also known as leukocytes, are larger and have a nucleus, while red blood cells, also known as erythrocytes, are smaller and lack a nucleus.
Numerous differences can be seen between frog blood and human blood. Perhaps the most obvious is the oval shape of the frog erythrocytes rather than the biconcave discs of human blood. Moreover, the frog erythrocytes have a nucleus (here stained blue) whilst human erythrocytes do not. There is less difference in size between the erythrocytes and leucocytes than in human blood. There are no platelets in frog blood.
Red blood cells (erythrocytes) outnumber white blood cells (leukocytes) and platelets (thrombocytes) because they comprise the majority of the cells in the blood and play a crucial role in transporting oxygen throughout the body. White blood cells are less numerous but are important for the immune system's defense mechanisms, while platelets are involved in blood clotting to prevent excessive bleeding.
When the total number of leukocytes in the circulating blood is less than normal, it is known as leukopenia. Leukopenia can be caused by certain medications, infections, autoimmune disorders, or bone marrow disorders. Having a low white blood cell count can increase the risk of infections and may require further evaluation and treatment by a healthcare provider.
