Chapter 5: Blood Flashcards
The blood is composed of what living cells?
Erythrocytes (red blood cells), Leukocytes (white blood cells), Thrombocytes (platelets).
What is the function of Erythrocytes (red blood cells)?
Erythrocytes are filled with hemoglobin and carry oxygen from the lungs to the rest of the body.
What is the function of Leukocytes (white red blood cells)?
Defend against infection.
What is the function of Thrombocytes (platelets)?
Help blood to clot when injuries occur.
What is blood responsible for?
For transporting oxygen to the cells and removing carbon dioxide for excretion by the lungs.
What does blood carries?
Nutrient, ions, water, hormones and enzymes to all body cells and carries away wasted products, blood regulates the PH and temperature of the body.
Blood is composed by the liquid portion of?
Plasma and solids call formed elements.
What is the total percentage of the total blood volume that makes up plasma?
55% and 91% which is H2O
What are the Plasma Proteins?
Albumin, Globulin and Fibrinogen
What is the fiction of Albumin?
Albumin maintain osmotic pressure and water balance.
What is the faction of Globulin?
Globulin antibodies to help the immune system and fibrinogen.
What is the function of FIbinogen?
An essential component for blood clotting.
Red blood cells have no nucleus and that causes?
That they don’t divide and. only live 120 days.
Why red blood cells have hemoglobin?
Because hemoglobin carries oxygen to all cells of the body and carries away carbon dioxide
What are the 5 types of white blood cells?
Three Granular and two nongranular
What does the granular types appear under the microscope?
They appear to have grains.
What are the three types of granular white blood cells?
Neutrophils, Eosinophils and Basophils.
What is the function of Neutrophils?
They phagocyte or eat up, foreign substance, and secrete lysosomes that destroy bacteria.
What is the function of Eosinophils?
They produce antihistamines that combat irritants.
What is the function of Basophils?
They are involved in allergic reactions, secrete heparin, histamines and serotonin.
What is the function of Monocytes?
They phagocytize bacteria and dead cells, and when they enter the tissue the are called macrophages.
What is the function of Lymphocytes?
They produce antibodies and are crucial to the body’s Immune system.
Bacteria are being destroyed by what?
By Neutrophils, Lymphocytes and Macrophages.
What initiates the chain reaction in clot formation?
Platelets.
