Cardiovascular System: Blood Flashcards
I based the flashcards from my notes. You can read more on Seeley's Essentials of Anatomy and Physiology (20 cards)
RBC
Erythrocytes
WBC
Leukocytes
Platelets
Thrombocytes
Normal Range of Blood pH
7.35 pH - 7.45 pH
Plasma to Formed Elements Blood Composition Ratio
55% : 45%
Volume of Blood allowable for donation
500 mL
Volume of Blood of which symptoms of shock appear
750 mL
It is biconcave, enucleated, and does not contain organelles. It is dedicated to respiratory gas transport.
Red Blood Cells/ Erythrocytes
In the context of blood, it is spherical and contains a nucleus, and associated with immune response.
White Blood Cells/ Leukocytes
These are cell fragments surrounded by a cell membrane and contains granules. They form plugs and release chemicals necessary for blood clotting.
Platelets/ Thrombocytes
WBC’s that are usually the first of the white blood cells to respond to infection.
They normally remain in the blood for about 10–12 hours and then move into other tissues. Once neutrophils leave the blood, they seek out and phagocytize bacteria, antigen-antibody complexes, and other foreign matter.
Neutrophils
WBC’s that are important in the defense against certain worm parasites. They release substances that kill the parasites.
Eosinophils
The least common WBC’s. They contain large amounts of histamine, which they release within tissues to increase inflammation.
They also release heparin, which inhibits blood clotting.
Basophils
These are the smallest WBC’s. Their activities include the production of antibodies and other chemicals. They are directly related to the Immune system.
Lymphocytes
These are the biggest WBC’s. After they leave the blood and enter tissues, they enlarge and become Macrophages that phagocytize bacteria, dead cells, cell fragments, and other debris.
Monocytes
It is an accumulation of platelets that can seal SMALL breaks in blood vessels.
Platelet Plug
This occurs when vascular spasms and platelet plugs alone are not sufficient to close large tears or cuts and the blood vessel is severely damaged.
Coagulation/ Blood Clotting
Blood groups are determined by ________ on the surface of red blood Cells.
Antigens
It is a blood group based on the presence of Rh Antigens. They are the additional positive or negative when referring to blood type.
Rh Blood Group
A type of anemia that results from mutations of the red blood cell in which the substitution of one amino acid (valine for glutamic acid).
sickle- cell anemia
