Hematopoiesis or hemopoiesis is the process by which all blood cells are formed.
Hematopoiesis
Blood cells are made in the bone marrow or stem cells of your body. The stem cells become red blood cells, white blood cells and platelets. Red blood cells are replaced every 120 days, platelets every 6-7 days and white blood cells everyday.
When blood passes through the lungs, oxygen from the alveoli diffuse into the capillaries and is taken up by red blood cells. There it binds to hemoglobin. The red blood cells will travel through the arteries to the tissues where the oxygen will disassociate itself from the hemoglobin and diffuse into the tissues (cells).
No. The two big examples of non-reproduction in humans is red blood cells and neurons.
A process known as diffusion. The plasma in your blood.

in the bone-marrow
Erythrocytes or red blood cells are formed in the bone marrow from precursor cells called erythroblasts which themselves are formed from pleuripotential stem cells - the mother of all blood cells. Along the way, erythroblasts take various forms/ stages until they differentiate into mature erythrocytes.
The formed elements of blood are related in that they are all the cells or cell fragments that comprise the solid portion of blood, and they arise from the same type of stem cell. The formed elements of blood are red blood cells (erythrocytes), white blood cells (leukocytes), and platelets (thrombocytes).
All gametes, including sperm cells, are formed through a process called meiosis.

formed elements
New red blood cells are formed by the red bone marrow located in the spongy bone in a process called hemopoesis. I hope that helps :-)
All blood cells (red and white) are formed in the bone marrow.
the process to make red blood cells is called erythropoiesis. they are produced in bone marrow and originate from hemotopoietic stem cells. this differentiation is stimulated by hormone erythropoietin. the process takes about 7 days and red blood cells last between 100 and 120 days when they are then recycled by the body. the process of making white blood cells also utilizes hemotopoietic stem cells. there are many different white blood cells such as neutrophils, basophils, monocytes, lymphocytes and eosinophils. they all perform different functions in immunity.
Technically yes they are because hemocytoblast stem cells create Myeloid stem cells and Lymphoid stem cells which produce all of the formed elements (white and red blood cells).
