Red Blood Cells
- 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.
- Have a deficiency in red cells, causes one to feel fatigued due to a shortage of oxygen.
- Iron Deficiency
-Treatment: Change in diet, and take iron supplements.
- Hemolytic Anemia
-Treatment: Avoid suspect medications, and drugs that suppress your immune system, which may attack your blood cells.
- Hemorrhagic Anemia
-Treatment: Try to stop the bleeding, restore blood volume with IV; saline, dextran, albumin, or plasma.
- Sickle Cell Anemia
-Treatment: Take pain-relievers.
- Pernicious Anemia
-Treatment: Hydroxocobalamin by injection, and blood transfusion.
- 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
- 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
- A shortage of white blood cells in the system, which can be caused by anemia.
- Treatment: Stimulating the bone marrow, by cytokine, or chemotherapy.
- A cancer of blood forming tissues hindering the body's ability to fight infection.
- Treatment: Chemotherapy, radiation, and stem-cell transplant.
- 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.
- 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.
