Heart Actions
Blood Vessels
Arterial System
Venous System
100
The cavity in which the heart is located
What is thoracic
100
Causes heart sounds in heart tissues
What is vibrations
100
Blood vessels are a closed tube that performs these actions
What is carries blood away from the heart, to cells, and then back to the heart
100
The body's largest artery
What is the aorta
100
Veins return blood to the heart after the exchange of this
What is substances in the tissues.
200
This structure encloses the heart
What is the pericardium
200
During the cardiac cycle, pressure within the heart chambers rises and falls with the contraction and relaxation of these
What is the atria and ventricles
200
The names of the five different blood vessels
What is arteries, arterioles, capillaries, venules, and veins
200
The branches of the ascending aorta
What is the right and left coronary arteries
200
Where veins from the upper head and torso drain
What is the superior vena cava
300
The number of internal chambers of the heart
What is four
300
Valve that opens when the atria pressure exceeds that of the ventricles
What is the A-V valve
300
The three branches of arteries
What is elastic, muscular, and arterioles
300
These branches supply the abdominal wall with blood
What is the abdominal aorta
300
Veins from the lower body drain here
What is the inferior vena cava.
400
The first branches of the aorta that carry freshly oxygenated blood to the heart muscle itself
What is the right and left coronary arteries
400
This node is innervated by branches of the sympathetic and parasympathetic divisions
What is S-A node
400
These are the smallest of the blood vessels
What is capillaries
400
The arteries that lead to the head, neck, and brain
What is subclavian and common carotid arteries.
400
What the upper limb is drained by
What is superficial and deep veins
500
These are the approximate measurements of the average adult human heart
What is 14 cm long and 9 cm wide
500
How the cardiac system functions
What is atria beating in unison followed by the contraction of both ventricles, then the entire heart relaxes for a brief moment.
500
This is another way that veins function apart from bringing blood back to the heart
What is blood reservoirs
500
The posterior cerebral arteries help form this the circle
What is Willis
500
These are major superficial veins
What is the basilic and cephalic veins
