Q

A. Know the composition of blood and the function of each piece

A
  1. red blood cells, which carry oxygen throughout the blood
  2. white blood cells, which fight infections
  3. platelets, which are cells that help you stop bleeding if you get a cut

Q

Understand how RBC carry oxygen, and what determines the observed color of a RBC under a microscope. What is hemoglobin?

A

Red blood cells carry a high concentration of a protein called hemoglobin. Hemoglobin contains iron, which attracts Oxygen molecules. So oxygen attaches to hemoglobin from the lungs, where there is a relative abundance of oxygen, and is carried to the tissues.

Q

what does the color of blood mean

A

CIRCULATING BLOOD IS A RATHER VISCOUS SUBSTANCE THAT VARIES IN COLOR DEPENDING ON THE AMOUNT OF OXYGEN IT IS CARRYING. THE HIGHER THE OXYGEN LEVELS THE BRIGHTER THE COLO

Neutrophil

A

Neutrophil: Neutrophil is one of the body’s main defenses against bacteria of fungel infection. They kill bacteria by phagocytosis(ingesting)

Q

what is anemia

A

A person who has a low hematocrit is referred to as being anemic. Anemia is a condition that develops when your blood lacks enough healthy red blood cells or hemoglobin. Hemoglobin is a main part of red blood cells and binds oxygen. If you have too few or abnormal red blood cells, or your hemoglobin is abnormal or low, the cells in your body will not get enough oxygen

Q

what is polycythemia

A

Polycythemia is considered when the hematocrit is greater than 48% in women and 52% in men.
Higher than normal hematocrit levels represent abnormally elevated red blood cell counts. High hematocrits can be seen in people living at high altitudes and in chronic smokers.

16
Q

what is leukocytosis

A

Leikocytosis: It is an increase in the white blood cell count. This indicates infection, hemmorage, metabolic disease and poison by chemicals.

17
Q

what is leukopenia

A

Leucopenia : Low white blood cell count, causes include virus and chemotherapy.

18
Q

what is polycyythemia

A

Polycythemia: This is when there are to many red blood cells, this is caused by a mutation in bone marrow, high altitudes, rigorous training

19
Q

if you have a antigens , what kind of antibodies do you have

A

If you have type A antigens on the surface of your red blood cells, you also have anti-B antibodies in your plasma

20
Q

what are antibodies

A

Antibodies are specialized proteins that travel thorough the blood stream and are found in bodily fluids. They are utilized by the immune system to identify and defend against foreign intruders to the body.

21
Q

if you have a antigens what kind of blood type do you have

A

a

22
Q

F. Know where blood cells are created in the body and know what hormone controls the production of RBC’s and where this hormone is produced.

A

All of the cells in the blood, red blood cells, all types of white blood cells, and platelets are made in the bone marrow. This happens primarily in the flat bones in your body such as the skull, the sternum, and the pelvis.

The role of erythropoietin is to control red blood cell production by regulating the differentiation and proliferation of erythroid progenitor cells in the bone marrow. Produced primarily in the kidney, erythropoietin circulates in the plasma and acts on target cells in the bone marrow.
