|
Platelets
|
|
Consist of 5 cell types(neutrophils, eosinophils, basophils, lymphocytes,monocytes) which are the bodies defense mechanism.
|
WBC (white Blood Cell)
|
|
Transports oxygen from lungs to tissue, carbon dioxide from tissue to lungs.
|
RBC (Red Blood Cell)
|
|
What is a fluid connective tissue with a matrix called plasma and several formed elements?
|
Composition and volume of whole blood.
|
|
what blood circuit is located on the right side of the body and function?
|
pulmonary circuit, starts at right side of heart and goes to lungs.
|
|
what blood circuit is located on the left side of the body and function?
|
systemic circuit, starts at left side of heart and oxygenates the body.
|
|
what vessels supply blood to the heart muscle cells?
|
coronary arteries
|
|
Function of arteries are?
|
carry blood away from heart
|
|
Function of Veins are?
|
Return blood to the heart
|
|
Function of capillaries are?
|
Exchange of gases(oxygen, carbon dioxide) remove nutrients and waste products of the blood.
|
|
What causes heart attacks?
|
Blocked coronary arteries
|
|
During contraction of the heart, (the chamber squeezes blood into the adjacent chamber or artery trunk).
|
Systole
|
|
During relaxation of the heart,(chamber of heart fills with blood for next cycle).
|
Diastole
|
|
The amount of blood ejected by a ventricle during a single heart beat?
|
Stroke volume
|
|
One complete heart beat, including arterial & ventricle Systole and diastole.
|
Cardiac cycle
|
|
Heart beat referred to as lubb what valves do what?
|
AV closes& semilunar valve opens(start of ventricular systole)
|
|
Heart beat referred to as dubb what valves do what?
|
semilunar valve closes(start of ventricular distole)
|
|
a unusal sound or extra heart beat is called?
|
A murmur
|
|
a force exerted against the vascular walls by the blood?
|
Blood pressure(BP) systole/distole or contract/relax of heart
|
|
The difference between systolic and diastolic pressures is called?
|
Pulse
|
|
Abnormally high blood pressure?
|
hypertension
|
|
Formation of fatty plaque in the walls of arteries, leads to circulatory impairment.
|
Atherosclerosis
|
|
air that moves in and out of the lungs is called?
|
pulmonary ventilation
|
|
exchange of oxygen & carbon dioxide between interstitial fluids & external environment.
|
External respiration
|
|
Absorption of oxygen and release of carbon dioxide from bodies interstitial fluids & external environment.
|
internal respiration
|
|
Mitochondrial activity responsible for ATP production
|
cellular respiration
|
|
single breath in (oxygen intake)
|
inhalation
|
|
single breath out (carbon dioxide release)
|
Exhalation
|
|
the amount of air moved in or out of lungs in a respiratory cycle
|
Tidal Volume
|
|
The amount of air that can be voluntarily expelled in a respiratory cycle
|
Expiratory reserve volume
|
|
the amount of air that can be taken in over and above resting tidal volume
|
inspiration reserve volume
|
|
the maximum amount of air that can be moved in or out respiratory system in a single respiratory cycle
|
Vital capacity
|
|
The amount of air that remains in lungs after maximal exhalation
|
Residual air
|
|
what part of brain are involved with respiratory control
|
Brain stem(pons, medulla)
|
|
the cessation of breathing
|
apnea
|
|
a increase of heart rate and depth of breathing
|
hyperventilation
|
|
a decrease in respiratory rate
|
hypoventilation
|
|
(inspiration /expiration)
diaphragm contracts & flattens, ribs lift, external intercostals contract, volume of thoracic cavity increases,pressure in thoracic cavity decreases,, air moves into lungs |
Inspiration
|
|
(inspiration /expiration)
diaphragm relaxes moves up(dome)ribs flex back(recoils) intercoastal muscles contract Thoracic volume decreases Thoracic pressure increases air moves out of lungs |
expiration
|
|
glucose+O2-->36ATP+CO2+H2O
