The aorta is classified as an?
Arteries
The vena cava is classified as an?
Veins
The "jugulars" are classified as ?
Veins
The "carotids" are classified as?
arterys
Blood vessels referred to as "Internal"are?
deeper blood vessels
Blood vessels that are referred to as "External" are?
more superficial
Theses clump together and stick to blood vessel walls.
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
Aerobic cellular respiration
how and where is oxygen transported in the blood?
RBC. lungs and body
how and where is CO2 carried in the blood
heme unit(RBC), plasma, H2OCO3(carbonic acid)
what keeps alveoli from collapsing
surfactant (surface tension)
what maintains O2,CO2,HP concentrations
chemoreceptors
