Blood

Red Blood Cells

Erythrocytes

  • Makes up 40%-50% of the total blood volume.
  • Appearance: Large microscopic cell without a nuclei. A red disk with indent in the middle.
  • Function: Transport oxygen from the lungs to all of the living tissues of the body and carry away carbon dioxide.
  • Maintain Homeostasis: carries out nutrients and getting rid of waste.
  • Hemocratic: A proportion, by volume of the blood that consist of red blood cell. Expressed as a percentage.
  • Hemoglobin: A gas transporting protein molecule that makes up 95% of a red cell. Each red cell has about 270,000,000 iron-rich hemoglobin molecules.

Anemia

  • Have a deficiency in red cells, causes one to feel fatigued due to a shortage of oxygen.
  • Iron Deficiency
-Cause is loss of blood, the source should be located and stopped.

-Treatment: Change in diet, and take iron supplements.

  • Hemolytic Anemia
-A blood transfusion may be necessary. In some cases removal of spleen may be helpful.

-Treatment: Avoid suspect medications, and drugs that suppress your immune system, which may attack your blood cells.

  • Hemorrhagic Anemia
-Sufficient decrease in red blood cells due to hemorrhages.

-Treatment: Try to stop the bleeding, restore blood volume with IV; saline, dextran, albumin, or plasma.

  • Sickle Cell Anemia
- May need bone marrow transplant. Also recommend blood transfusions. When red blood cells become misshapen and break down.

-Treatment: Take pain-relievers.

  • Pernicious Anemia
-A decrease in red blood cells when the body can't absorb enough vitamin.

-Treatment: Hydroxocobalamin by injection, and blood transfusion.

Polycythemia

  • Increased concentration of hemoglobin in the blood, by reduction of plasma volume or increase in red cell numbers.
  • Treatment: control the symptoms.
  • Phlebotomy is a procedure that removes some blood from your body.

Donating Blood Process

  • Take a mini-physical and check up on health history
  • They clean a small portion of your arm.
  • Then insert a sterile needle to draw the blood.
  • Takes 8 to 10 minutes, platelets and plasma take up to 2 hours.
  • When a pint of blood is collected the donation is complete

Time between donations

  • You must wait 8 weeks or 56 days
  • For plasma you must wait 16 weeks or 112 days.


Life of Blood

  • Blood is good for 42 days
  • One year for frozen Plasma
  • 5 Days for Platelets to be stored


Use for Blood

  • Used for treatment of all kinds of anemia which can't be medically corrected.
  • For loss of blood from accidents, surgery, and after child birth.

White Blood Cells

Leukocytes

  • Exist in variable numbers and types but make up a very small part of the bloods volume, normally only 1%
  • Apperance: White ball/sphere like shape with a rough looking surface.
  • Function: First responders for our immune system. They seek out bacteria, viruses, and fungi so they can be removed.
  • Maintain Homeostasis: Protect bodies immune system by fighting off viruses.
  • 5 types of white blood cells
  1. Neutrophils
  2. Basophils
  3. Eosinophils
  4. Lymphocytes
  5. Monocytes

Platelets

Thrombocytes

  • Crucial to normal blood cloting.
  • Fragments of a large cells called a megakaryocte.
  • Maintain Homeostasis: They adhere to the walls of blood vessels.
  • Thirteen different blood clotting factors, need to interact for clotting to occur.
  • They do that in a cascading manner one triggering another.

Plasma

  • Yellow tinted water, sugar, fat, protein, and salt solution which carries the red cells, white cells, and platelets.
  • Normally, 55% of our blood's volume is made up of plasma.
  • Plasma brings nourishment, and removes the waste produced by metabolism.
  • People get paid for donating plasma because it treats rare chronic disease.
