List the functions of blood. (3)
1.) Transport 2.) Regulation 3.) Protection Transport: oxygen, carbon dioxide, wastes and molecules. Regulation: PH of fluids, maintaines body temp and fluid levels in the body. Protection: antibodies in the blood defend against disease.
What is the normal volume of blood?
5 to 6 liters
What is the normal pH range of blood?
7.35 to 7.45
Which type of leukocytes is in the lowest percentage in blood?
Basophils
What is anemia?
Condition that results in less than normal hemoglobin in the blood or a lower than normal number of red blood cells.
What is a hematocrit?
Percentage of total blood volume composed of red blood cells.
What is the normal percentage of plasma and RBC in a hematocrit?
Plasma-55% RBCs-4.2 - 6.2 million Plasma-fluid portion of blood composed of 90% water and 10% solutes ***plasma is 55% and red blood cells are 45% and white blood cells, etc. make up less than 1%.
What is hemostasis?
to stop bleeding.
What is agglutination and the problem that occurs with mismatched blood transfusions?
where the foreign red blood cells are clumped together and lodge in the kidney, causing multiple problems.
Name the three "formed elements" found in blood and their functions.
1.) Erythrocytes (Red Blood Cells) 2.) Leukocytes (White Blood Cells) 3.) Thrombocytes (Platelets) Erythrocytes:red bood cells: They contain hemoglobin and their main function is to carry oxygen to all the body cells. Leukocytes:white blood cells:protect the body against microorganisms causing disease thrombocytes:platelets:The function of platelets is the maintenance of hemostasis, help blood clot.
Name the different types of leukocytes.
1.) Neutrophils 2.) Lymphocytes 3.) Monocytes 4.) Eosinophils 5.) Basophils
What is plasma?
Fluid portion of blood; blood minus the formed elements.
Which type of leukocytes is in the highest percentage in blood?
Neutrophils
When is Rh factor dangerous to a pregnant woman and her unborn child?
Problems occurs when a woman who is Rh negative has a baby who is Rh positive and during delivery their blood may mix.
What is leukemia?
Tumor of the red bone marrow that results in the production of large numbers of abnormal white blood cells; often accompanied by decreased production of red blood cells and platelets.
What is the ABO system of blood typing?
a system is used to categorize human blood.
Name the elements critical for normal clotting to occur.
clotting factors, vitamin K, and calcium
What is the Rh factor?
is another type of protein that can be on the outside of red blood cells.
How does leukemia compare to leukocytosis?
they are both an increase in the number if white blood cells (WBCs)
