White blood cells form in response to an infection. As soon as the body detects a viral or bacterial infection, the immune system starts producing an army of white blood cells. They are produced in the bone marrow.
By a process called hematopoesis in the bone marrow
Blood is formed in the red bone marrow at the epiphysis (ends) of long bones, such as the femur.
Blood cells are made in the bone marrow

There are roughly 5 liters or 1.3 gallons of blood in the average adult human being. Blood accounts for 8% of body weight. Whole blood is composed of approximately 45% red blood cells, 54.3% plasma and 0.7% white blood cells.
Yes and No. The only big difference is the procedures used in harvesting adult stem cells is considered legal and safe. There's no need to kill a human embryo. Adult stem cells can be harvested from cord blood or human bone marrow. But embryonic stem cells are able to make more kinds of cells than adult stem cells.
Yes, blood is composed of formed elements and the liquid matrix called plasma. The formed elements of blood are red blood cells (erythrocytes), white blood cells (leukocytes), and platelets (thrombocytes).
Red blood cells are the most numerous in the blood. They are much smaller than any of the other cells. An adult has about 25 trillion red blood cells, which is about a quarter of the total number of cells in the human body.The red blood cells carry oxygen throughout the body and help carry away carbon dioxide.Red blood cells are also called erythrocytes.White blood cells are not the most numerous cells in the blood.Red blood cells are the most numerous cells in the blood and in the body. They are very small but numerically they comprise roughly one quarter of the cells in the human body.Read more: Are_white_blood_cell_the_most_numerous_cells_in_the_blood
Frog red blood cells contain a nucleus, whereas human red blood cells do not.
Blood cells are formed in red bone marrow of long and other bones . some Blood cell mature in lymph nodes , thymus gland (and Bursa of Fabricious in birds)
Red bone marrow
They aren't. Neurons are brain matter, and those cells don't regrow.

You can find red blood cells, white blood cells, and platelets in human blood.

Epithelial cells, such as those lining the intestines or skin, divide frequently in adult humans to help maintain and repair tissues.

The adult is bigger so it needs more cells than a baby.
Frog red blood cells contain a nucleus, whereas human red blood cells do not.
The shape of the human red blood cells is that it is biconcave in shape.
