Blood Worksheet Flashcards
B. Know the constituents of plasma and they function they serve
Water-Provides a liquid medium in which cells can travel
Proteins-Their role is to maintain balance. There are also proteins that are antibodies.
Gases-regulates blood pH
Nutrients-used for producing energy.
Hormones –various uses
Waste-for removal from the body
Electrolytes-for regulating osmotic balance and maintaining pH.
A. Know the composition of blood and the function of each piece
- red blood cells, which carry oxygen throughout the blood
- white blood cells, which fight infections
- platelets, which are cells that help you stop bleeding if you get a cut
- plasma, a yellowish liquid that carries nutrients, hormones, and proteins throughout the body
Erythrocytes=
Erythrocytes=O2 transport to tissue and removal of CO2 from tissues
Leukocyte=
Leukocyte=immune defensive functions (antibody production)
Platelets=
Platelets= hemostasis (coagulation)
Understand how RBC carry oxygen, and what determines the observed color of a RBC under a microscope. What is hemoglobin?
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.
what does the color of blood mean
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
Hemoglobin =
Hemoglobin =(Hb or Hgb) is the protein in your red blood cells that carries oxygen.
Neutrophil
Neutrophil: Neutrophil is one of the body’s main defenses against bacteria of fungel infection. They kill bacteria by phagocytosis(ingesting)
Eosinophil:
Eosinophil: Eosinophil deal with parasitic infections
Basophiles:
Basophiles: functions in alergic reactions. Basophil releases histamine
Lymphocyte:
Lymphocyte: Lymphocte is responsible for immune responses. There are 3 types of lymphocyte cells: B cells, T cells and Natural killer cells.
Monocyte:
Monocyte: These cells destroy old,damaged and dead cells.
what are the noram hematocrit levels for men and women
- Adult males: 42% to 54%
* Adult women: 38% to 46%
what is anemia
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
