How many types of cells in the blood?
|
6 - Erythrocytes, Neutrophils, Lymphocytes, Monocytes, Eosinophils, Basophils.
|
|
|
Erythrocytes (red blood cells) make up what percentage of all blood cells?
|
99%
|
|
|
Lycocytes (white blood cells) are found where in the body?
|
within organs and tissues, not circulating in the blood.
|
|
|
Name the five types of Lymphosytes.
|
Neutrophils, Lymphocytes, Monocytes, Eosinophils and Basophils.
|
|
|
What is blood?
|
It is a connective tissue, composed of plasma and formed elements.
|
|
|
What is plasma?
|
It is a yellowish, clear, nonliving fluid matrix composed primarily of water.
|
|
|
Describe Neutrophils -
|
Most abundant, the leukocyte to the site of a break in the first line of the body's defense.
the nucleus can have 3 - 7 lobes. |
|
|
Describe Lymphocytes -
|
the smallest, synthisizes antibodies, and transformed cancerous cells, also involved in graft-rejections.
|
|
|
Describe Monocytes -
|
Largest, kidney-shaped, their numbers increase during chronic infections and provoke a fever within the body.
|
|
|
Describe Eosinophils -
|
Shaped like ear-muffs, primary function is to ingest and destroy foreign material.
|
|
|
Describe Basophils -
|
Shaped similar to a butterfly, very granular, contains histamine which is involved in the inflammatory response and heparin which prevents blood clotting.
|
|
|
What a Platelets?
|
They are not cells, but are small pieces from a very large cell called a megakaryocyte. Contain actin and myosin and are capable of contraction. Required for the process of blood clotting.
|
|
|
What is Hematocrit (Hct)?
|
Blood doping, When the blood is centrifuged, plasma and formed elements separate. This represents the volume of RBC and a measure of the oxygen carrying capacity of blood.
|
|
|
What is Hemoglobin?
|
The molecule that carries oxygen from the lungs to the tissues and carbon dioxide from the tissues back to the lungs.
|
|
|
What is Serum?
|
Plasma wit hcells and clotting proteins removed.
|
|
|
What is Agglutinate?
|
when antibodies cause RBCs to clump together.
|
|
|
What is the Circulatory system composed of?
|
pulmonary and systemic
|
|
|
What is the pulmonary system?
|
it's the low pressure, low resistance system carrying blood from the heart to the lungs, where it picks up oxygen and gets rid of carbon dioxide.
|
|
|
What is the systemic system?
|
it carries oxygenated blood from the heart to the body and deoxygenated blood back to the heart.
|
|
|
What is the hole sometimes found in an infant's heart?
|
Foramen Ovale (opening)
|
|
|
What is plasma?
|
It is a yellowish, clear, nonliving fluid matrix composed primarily of water.

|
|
|

|
Shaped like ear-muffs, primary function is to ingest and destroy foreign material.
|
|
|
Which veins carry blood into the heart?
|
Pulmonary veins
|
|
|
What is the "lubb" sound?
|
it's the first heart sound made as the atrioventricular valve close at the beginning of ventricular systole.
|
|
|
What is the "dubb" sound?
|
it's the second sound made as the semilunar valves close at the beginning of ventricular diastole.
|
|
|
What is auscultation?
|
the process of listening to heart sounds
|
|
|
What is the instrument used for taking blood pressure?
|
sphygmomanometer
|
