Which Part of the Body Makes Blood?
Mar 16, · Red blood cells, which are produced in bone marrow, contain and transport oxygen throughout the body, and also includes the protein hemoglobin, which makes blood look red. Red blood cells can live up to days before they die off. The other 10% of blood is . Sep 30, · Bone marrow is mainly how the body makes blood. It is forms inside the marrow of the body's longest bones, like the arms, legs and back. Cells .
Blood is a mixture of substances in the body mainly comprised of four parts. It has red and white cells, plasma and platelets. Platelets are tiny pieces of cells that enable us not to bleed to death when we are injured.
When we get cut, platelets race to the wound and stick there. Plasma is the fluid part of blood which is just a mixture of sugars, proteins, thhe and other parts like potassium and magnesium.
Red cells have hemoglobin, which is extremely important. Hemoglobin is responsible for carrying oxygen to the cells--without oxygen, the cells will die. White cells are makees portion of the blood which contains antibodies. People are constantly bombarded by bacteria and outside infectious agents, from the environment, for example. Without antibodies, we would not be able to fight off disease. Bone marrow is mainly how the body makes blood.
It is forms inside the marrow of the body's longest bones, like the arms, bloo and back. Cells fill in the tiny arteries inside the bone by a process known as hematopoiesis. Basically, there is genetic material that determines what cells will become and where in the body they will end up.
Hematopoiesis happens when the body uses its stem cells to enable a person to create new cells. You need to be able to make new cells to generate enough blood volume to keep organs like the spleen, liver and heart alive. At any given yhe, a person has about five liters of blood in their body. This equates to about a gallon or so. After the blood forms in the marrow, it has to be disbursed throughout the body by the circulatory system--to replenish the organs with oxygen and nutrients.
The electrical system of the body allows the heart to beat at a certain rhythm. Because of this, the chambers of the heart, also called the atria and ventricles, expand and contract at a regular pace sending blood back and forth through it. One group of chambers pull the blood in, while the other sends the blood out.

Blood is comprised of about 78 percent fluids and 22 percent solids. The primary components include plasma the liquid portion , red blood cells erythrocytes , white blood cells lymphocytes, monocytes, eosinophils, basophils and neutrophils and platelets.
All of the blood cells arise from your bone marrow, primarily of the long bones in the arms, legs, back and sternum.
Bone marrow has yellow marrow, which contains fat, and red marrow, which contains hematopoietic blood-forming stem cells. Plasma carries the blood cells as well as antibodies, vitamins, minerals, electrolytes such as sodium, calcium and potassium , proteins and clotting factors which help the blood to clot throughout the body.
When you eat and drink, nutrients and fluids are absorbed into the blood from the small and large intestine, replenishing the plasma and allowing it to circulate the blood cells and nourish the body systems.
Red blood cells erythrocytes comprise about 40 percent of the blood. Red blood cells produce hemoglobin, which carries oxygen from your lungs to the tissues and carbon dioxide back to your lungs. Red blood cells are formed in your bone marrow and become disk-shaped as they mature, allowing them to change shape to get through narrow vessels.
They normally live about days. When oxygen levels in the blood begin to fall, your kidneys secrete erythropoietin to signal the bone marrow to increase production of red blood cells. Sometimes, if your body is anemic, the bone marrow tries to produce more and more red blood cells to compensate, causing release of reticulocytes immature red blood cells.
White blood cells leukocytes are also produced in your bone marrow and comprise only about 1 percent of the blood volume; however, they increase in number in response to body needs, such as with infection, injury or allergies. The different types of white blood cells specialize in different defense mechanisms to protect the body.
Most white blood cells mature outside of the bone marrow in lymphoid tissue, such as in the adenoids, spleen or thymus. Many do not circulate all of the time but "rest" until activated. Platelets thrombocytes are fragments that break off a large cells called megakaryocytes. The megakaryocytes mature and remain in your bone marrow, but as the platelets break off, they enter your blood stream as small disk-shaped fragments.
When an injury or bleeding occurs, the platelets change shape, growing pseudopodia false feet , allowing them to stick together to form a clot. Wanda Lockwood has an R.
