When blood pressure is high, the Vagus nerve stimulates the SA Node to speed up the heart beat - True or False
TRUE
FALSE
Which valves are classified correctly?
The heart can beat outside the body because...
The sinoatrical node is found outside of the heart
Contraction and relaxation signals exist within the heart itself
The heart is able to fully relax
The 4 chambers send chemical messengers to each other
Venous return in veins that pass through the thoracic cavity is increased by the:
skeletal muscle pump
pumping of the right ventricle
pumping of the left ventricle
respiratory pump
If a large amount of blood was lost because of a large wound, blood pressure would?
Increase
Decrease
Remain the same
Increase, then decrease
Smooth muscle contraction in the blood vessels increases blood pressure because it:
increases blood volume
decreases blood volume
causes vasoconstriction
causes vasodilation
When oxygen levels decreases, the kidneys secrete:
renin
more water
erythropoietin
all of these

vein
artery
capillary
both veins and capillaries
The chamber that receives oxygenated blood from the lungs
Right Ventricle
Left Ventricle
Right Atrium
Left Atrium
What is colloid osmotic pressure?
Fluid leaves the capillaries into the tissue because of pressure gradients
The return of fluid into the capillaries via osmosis due to the concentration of blood proteins
The movement of water into the tissue following oxygen diffusion
Pressure in the capillary beds to the heart beating
The first heart sound ('Lub') of the heart is caused by...
Atrioventricular valves closing
Semilunar valves closing
Blood flowing through the Pulmonary artery and aorta

An IMMATURE red blood cell is called
leukocyte
erythrocyte
thrombocyte
reticulocyte
Where do the pulmonary arteries transport the blood to?
lungs
heart
head
hands
The opening of semilunar valves is due to
increased ventricular pressure
decreased ventricular pressure
increase in artrial volume

The ventricle is the
Upper chambers
Lower chambers
Right side
left side
What is the function of the veins?
to gather oxygen poor blood throughout the body in order to take it back to the heart
to gather oxygen rich blood throughout the body in order to take it back to the heart
to pump blood throughout the body
they don't have a function
