Red bone marrow.
Bone marrow (red)
Bone marrow
Blood cells are produced from bone marrow. This is gel like substance that is located inside the bone.
Spongy Bone- open specs that provide supportCompact Bone- rigid/dense bone made of connective tissue
It is a major contributor of white blood cells, red blood cells and platelets. It also has cells in the bone itself that make and break down bone called osteoblasts and osteoclasts.
Red blood cells, which make up the bulk of blood, are produced from stem cells in the bone marrow. Stem cells reproduce in bone marrow and provide the raw material from which red blood calls can be produced. A pluripotent (undifferentialted) stem cell becomes a multipotent stem cell, which in turn becomes a unipotential stem cell, which is to say it is now a specialized cell destined to become a specific type of blood cell. . After going through a few more stages it is released from the bone marrow, and ultimately becomes an erythrocyte, or mature red blood cell. White blood cells, which are actually immune cells, are also produced in bone marrow from pluripotential hematopoietic stem cells, but go thorugh different stages to eventually become one of the six types of immune cells classified as white blood cells.
Blood cells, both red and white, are produced in the bone marrow. Nutrients and water are added from the digestive system. And together they make blood.
No the heart does not make blood- the blood is made by the bone marrow.
Bone marrow is the part of the bone responsible for making blood cells. It is a soft, spongy tissue found within the center of bones and is essential for the production of red blood cells, white blood cells, and platelets.
your bone marrow
No, the heart does not work hard to make blood cells. In fact, it does no work at all. Blood cells are produced in bone marrow, in cancellous bone tissue (or 'spongy tissue') within the hard casings of bone. A hormone (protein with a very specific role in the body) called 'erethropoeitin' (erethro = red blood cell, poeitin = producing) stimulates red blood cell (erethrocyte - erethro = red, cyte = cell) production within the bone marrow. Ooh I nearly forgot - the main bones with spongy bone tissue (ie. the bones that produce red blood cells) are some of your rib bones, and femur bones. The heart's got it's work cut out for it just by pumping your blood (a mixture of red blood cells AND plasma, as well as 1% 'buffer substance') around your body. If you are reading this, it means you're old enough that your heart would have pumped millions of litres of blood through your body. And by this I mean your blood volume, circulating many times. Don't forget that red blood cells only hang around for about 120 days before they break down. :)
bone marrow produces blood cells. There are three types of blood cells; red blood cells, white blood cells, and platelets.
