Cardiovascular system Flashcards
(126 cards)
Test to determine % of each kind of wbc
Differential wbc count
Sagging, swollen superficial veins distorted by gravity and failure Of valves
Varicose veins
when artia relax, ventricles contract, av valves close, and semilunar valves open is what part of the heartbeat
ventricular systole
what is the term for the cardiac pacemaker of the heart that initiates electrical impulse and spreads to the cardiac cells of the atria and to the other half of the pacemaker about 100 msec slower than to that of the atria
the Sinoatrial node or the SA node
Disease/ disorder with a bulge in a weakened wall of blood vessel (usually an artery)
Aneurysm
Type of shock due to pathogens releasing toxins into blood stream and dilates blood vessels
Septic shock
plasma proteins that transports hemoglobin, copper, lipids, vitamins, hormones, and iron, which also aid blood clotting, destruction of toxins, and antibodies
globulins
Abnormal patterns of cardiac electrical activity is called
Cardiac arrhythmia
what is the function of an av valve
prevents backflow into atriums of heart
the measurement of an artery expanding and then recoiling
pulse
list some specific functions of transportation in the blood
- carries o2 and co2 between lungs and tissues of body
- carries nutrients from digestive system and storage areas to rest of body
- carries wastes to the liver and kidneys for detoxification
- carries hormones from endocrine glands to target tissues
List some functions of blood related to homeostasis
- regulates temp by moving heat from skeletal muscles to superficial blood vessels
- transfers water and electrolytes to and from tissue to stabilize balance
- stabilizes ph with buffers
what are the two names for the serous membranes that attach to the myocardium
the visceral pericardium and the epicardium
what is the name for the part of the heart wall that lines the inner surface of heart chambers and valves?
endocardium
Technique to reduce coronary plaque by inserting a catheter and inflating a balloon
Balloon angioplasty
wbc type that is the most and least common
most: neutrophils
least: basophils
type of blood vessel that carries deoxygenated blood from capillary beds towards larger vessels
venules
chemical reaction chain in blood clotting process
prostaglandins»_space;> prothrombin+calcium»> thrombin»> fibrinogen»> fibrin
Process of producing formed elements is called..
Hemopoiesis
talk me through the blood clotting process
- platelets in circulation break over injury cite, and cause a prostaglandin (platelet factors) reaction which triggers the start of blood clotting.
- platelets attach at injury site to act as a temporary plug and prostaglandins constrict blood vessel
- initiate reaction between plasma protein called prothrombin, calcium (+other substances) to form thrombin
- thrombin reacts with fibrinogen (in plasma) to create fibrin (jelly substance) to make a web over platelets and traps rbc to make a more permanent plug
- prostaglandins after clot is formed will stimulate blood clot shrinkage and vessel cell growth or healing
Test in which radioactive dye is injected via catheter into coronary arteries and using a x ray to see abnormalities
Coronary angiogram
Cancer of red bone marrow to have an abnormal wbc production
Leukemia
what is the fetal bypass that shunt blood from right atrium directly into the left atrium to skip a visit to the lungs called?
foramen ovale
what is the term for the movement of blood from left ventricle to right atria
systemic circuit
