Blood Flashcards
The reflexes by which BP is maintained are known as:
Baroreflex
What is the bainbridge reflex:
An increase in venous return
Valsava maneuver:
Forced expiration against a closed glottis produces increased intrathoracic pressure
Chemoreceptor reflex:
Chemosensitive cells located in the carotid bodies and the aortic body respond to changes in pH status and blood oxygen tension
Baroreceptor reflex:
Baroreceptors are mechanoreceptors that detect changes in pressure
RBC’s aka:
Erythrocytes
Blood platelets aka:
Thrombocytes
White blood cells’ aka:
Leukocytes
5 main types of white blood cells:
Neutrophils, lymphocytes, monocytes, eosinophils, and basophils
What is the liquid component of blood?
Plasma
Low number of white blood cells?
Leukopenia
Abnormally high number of white blood cells?
Leukocytosis
Neutrophils:
Help protect the body against infections by ingesting bacteria and debris
Lymphocytes:
Consist of 3 main types:
T lymphocytes and natural killers–help protect against viral infections and can detect and destroy some cancer cells.
B lymphocytes–develop into cells that produce antibodies
Monocytes:
Ingest dead or damaged cells and help defend against infectious organisms
Eosinophils:
Kill parasites, destroy cancer cells, and involved in allergic reactions
Basophils:
Participate in allergic reactions
Important in regulating BP and temperature, accounts for more than half of total blood volume, and consists of water, electrolytes, and proteins :
Plasma
