The arteries are thicker and more elastic than the veins because of which of the following ?
A: Arteries are under greater pressure
B: veins return blood to the heart against gravity
C: arteries have more blood flowing through them than veins

A: it is called systole, and is the phase when the heart is relaxing
B: it is called systole , and is the phase when the heart is contracting
C: it is called diastole, and is the phase when the atria are relaxing while the ventricles are contracting
D: it is called diastole, and is the phase when the heart is contracting
It is called systole, and is the phase when the heart is contracting

B: veins carry oxygenated blood
C: veins carry blood back to the heart
D: veins carry blood away from the heart
Veins carry blood back to the heart
Closed double loop system
What are the two parts and describe?
Pulmonary : Carries deoxygenated blood from the right ventricle to the lungs where it is oxygenated to the left atrium
Systemic: Carries oxygenated blood from the left ventricle to the body and returning deoxygenated blood to the right atrium
Oxygenated blood passes through which of the following?
A:Pulmonary and aortic valves
B: Right and left atrioventricular valves
C: Tricuspid and bicuspid valves
D: Mitral and aortic valves
D: Mitral and aortic valves
Which of the following is the consequence of increased hemoglobin in the blood?
A: Increased ability of the blood to carry oxygen to the tissues
B: Increase in leukocyte count
C: Decrease in immune response
D: Increase in blood volume
A: Increased ability of the blood to carry oxygen to the tissues
Which of the following is the order of vessels a red blood cell would follow after leaving the left ventricle?
A:Artery, vein, capillary, arteriole, venule
B: Artery, arteriole, capillary, venule, vein
