Peripheral resistance affect
the length of myocardial fibers.
Blood pressure and blood flow
cardiac out put
elasticity of the heart.
A decrease in total plasma volume results from the _____ effect
atrial natriuretic hormone
antidiuretic hormone
renin-angiotensin
aldosterone
Vasomotor control mechanisms regulates
diameter of capillaries.
cardiac output.
stroke volume.
diameter of arterioles.
_______ increase the total blood volume.
ADH
Aldosterone
ANP
noradrenaline
The stimulus that causes the release of ADH hormone into the blood to maintain water balance is
increased osmolality of the blood
dilution of solutes in the blood
high blood pressure
low concentration of salt in blood
Renin, a protein that is important in blood pressure regulation is released by the
kidney
heart
liver
lungs
Which of the following best illustrates the sequence of what will happen when the body experiences increased blood pressure?
Sensors detect increased pressure--> signal sent to brain--> blood vessels dilate--> pressure decreases
brain detects increased pressure--> signal from brain to sensors--> signal blood vessels dilate--> pressure decreases
Baroreceptors sense increased pressure-->signal sent to brain--> signal to circulatory system--> blood vessels dilate--> pressure decreases
brain detects increased pressure--> signal from brain to senseors--> signal from sensors to circulatory system--> pressure decreases
Arteries contain valves that prevent backward flow of blood.
true
false
Type of circulation that brings blood from the aorta to the myocardium and back to the right atrium through the coronary sinus
Cardiopulmonary Circulation
Coronary Circulation
Fetal Circulation
Portal Circulation
Blood pressure measured when the ventricles are relaxed
Diastolic
Pulse
Venous return
Systolic
Elastic arteries are present where pressure is the highest
closest to the heart where
away from the heart
in peripheral tissues
in brain
Fatima has blood pressure 183/81, what is Fatima's systolic pressure?
81
183
183/81
81/183
Blood pressure is used to determine
electrical current though the heart
function of coronary artery
if adequate blood is getting to tissues.
Speed of blood through veins
Type of circulation that brings blood from the aorta to the myocardium and back to the right atrium through the coronary sinus
Cardiopulmonary Circulation
Coronary Circulation
Fetal Circulation
Portal Circulation
Principal artery located in the upper arm and elbow
Renal
Axillary
Brachial
Radial
Narrowing of the arteries caused by deposits of fat forming along the walls of the arteries
Arteriosclerosis
Atherosclerosis
Aneurysm
Vasodilatation
Arteries have thicker walls in proportion to their lumen.
True
False
Interstitial fluid can be absorbed by the blood capillaries because of blood's high osmotic pressure
True
False
During inspiration, the pressure in the plural cavity is decreased this cause the increase venous return
true
False
The compression of Skeletal muscles of the legs do not help venous return
True
False
ACE inhibitors, or angiotensin converting enzyme inhibitors, are used to: Control high blood pressure (hypertension)
True
False
Angiotensin stimulates the release of aldosterone from the adrenal cortex to promote sodium retention by the kidneys
True
false
Increased output from the baroreceptors stimulates which center cardioacceleratory center
true
False
