the Cardiovascular Sytem Crossword Puzzle

QUESTIONS LIST:

• increases: left ventricular pressure _ during systole
• vein: this type of blood vessels carries blood back to the heart
• baro receptors: these monitor blood volume and pressure inside the blood vessels
• hypertension: when blood pressure is above 140/90 mm hg
• right: the _ atrium receives oxygen-poor blood via the inferior and superior vena cava veins
• left: the _ atrium receives oxygen-rich blood via the left and right pulmonary veins
• atrioventricular: the right and left atria pump blood to their respective ventricles through the right and left _ valves
• pulmonary: the right ventricle pumps blood through the _ valve into the _ artery
• aortic: the left ventricle pumps blood through the _ valve into the aorta
• contractile: _ cells are responsible for the mechanical work of pumping
• auto rhythmic: _ cells initiate and conduct action potentials that lead to muscle contraction
• sinoa trial: the _ node is responsible for setting the pace of the heart
• node: the atrioventricular _ delays electrical impulses, allowing the atria to contract before the ventricles
• systole: the contraction phase of the heart cycle
• diastole: the relaxation phase of the heart cycle
• resistance: blood flow is determined by the pressure gradient divided by _
• histamine: this is released when tissues are damaged, leading to vasodilation and an inflammatory response
• capillary: this type of blood vessel connects arteries and veins
• bulk: _ flow is the mechanism that maintains fluid balance between blood and the extracellular space
• artery: this type of blood vessel carries blood away from the heart to the body
• intera trial: the _ pathway conducts pacemaker activity from the right atrium to the left atrium
• inter nodal: the _ pathway conducts pacemaker activity from the sa node to the av node
• closing: the first heart sound “lub” is caused by the _ of the atrioventricular valves, while the second heart sound “dub” is caused by the _ of the aortic and pulmonary valves
• heart rate: this is regulated by the parasympathetic and sympathetic nervous systems
• hypotension: orthostatic _ can occur when standing up from a sitting or lying position
