Bone - surprising to many people - is vascular, which means it has a plentiful access to blood. So, since it has blood vessels running though it, especially the spongy bone at the ends of long bones, it is quite easy for the blood cells that form in red bone marrow to find their way into the blood stream.

∙ 11y agoRed blood cells are formed in the red bone marrow of bones. Stem cells in the red bone marrow called hemocytoblasts give rise to all of the formed elements in blood. If a hemocytoblast commits to becoming a cell called a proerythroblast, it will develop into a new red blood cell.
The formation of a red blood cell from hemocytoblast takes about 2 days. The body makes about two million red blood cells every second.
Blood is made up of both cellular and liquid components. If a sample of blood is spun in a centrifuge, the formed elements and fluid matrix of blood can be separated from each other. Blood consists of 45% red blood cells, less than 1% white blood cells and platelets, and 55% plasma.
I have MDS w/CML, Hematologists and Oncologists have explained this thoroughly and have read medical journals to learn as much as possible.
Addition: To answer your question more specifically; Bone marrow has a vascular compartment (The medial compartment located beneath the inguinal ligament for the passage to the femoral vessels and separated from the muscular lacuna-a cavity between muscle by the iliopectineal arch or artery) and an extravascular compartment (situated or occurring outside a vessel or the vessels) , hematopoiesis (the forming of new blood cells) takes place in the extravascular compartment (where cells are developing) blood cells, plasma cell, macrophages and fat cells. The vascular compartment is supplied by a nutrient artery which branches into central longitudinal arteries which send out radial branches that eventually open into sinuses (non nasal). These sinuses converge into a central vein that carries the blood out of the bone marrow into the general circulation.

How do white and red blood cell differ in structure?
white and red blood cells have 2 different shapes because they have 2 different functions in the body.
What type of tissue would a white blood cells be found?
White blood cells are also known as leukocytes. Blood is considered connective tissue. Some white blood cells leave the blood and migrate to areas of infection.
Do white blood cells have the ability to migrate from blood stream and lymphatic system into other tissues?
Yes they do.
Can somebody leave white blood cells in the hospital?
yes,it will be mixed in blood
What makes red and white blood cells?
Red blood cells contain iron which makes them reddish. White blood cells contain lysosomes which are used to breakdown foreign invaders, such as pathogens in the blood stream.
Why do white blood cells need to be able to change shape in order to accomplish their function?
White blood cells need to be able to change shape so that they can move into and out of the blood stream. This process is known as diapedesis.
Who are the cops of your blood stream?
White blood cells defend the body against infection from bacteria, viruses, fungi, and parasites.
What kind of organisms do red blood cells attack?
Red blood cells do not attack other organisms, it is the white blood cells that do this. All the red blood cells do is contain hemoglobin to transport oxygen round the body. They are themselves attacked by malaria parasite.
What is the importance of going for a WBC count?
A white blood cell count test will tell you how many white blood cells you have in your blood stream. If you have an infection or are suffering an allergic reaction your body will produce more white blood cells, so this will be picked up by the test.
How does your blood helps to protect us against germs?
Your blood travels all over your body. The white blood cells, which are the disease fighting cells, travel with it. Some of these white cells will leave the blood and migrate to an inflamed area.
Why do you not get symptoms when reinfected?
white cells (phagocytes, lympochites and platelets) are left in your blood stream after original infection, and still have the imprint of how to fight, or at least reduce the symptoms of the infection. an additional bit of information, if a large amount of white cells are left in the blood stream, or your body randomly produces excess amounts of white cells, meiopathy occurs in which the cells attack healthy muscular tissue.
What cell type is d first to leave the blood and enter infected tissues?
White blood cells
