How many cranial nerves are there - correct answer12

what nerve is the trigeminal nerve - correct answer5

what parts does the trigeminal nerve control - correct answersupplies sensation to the teeth and jaw

what are the 2 components of the autonomic nervous system? - correct answersympathetic nervous system

parasympathetic nervous system

what nervous system "speeds things up" - correct answersympathetic

what nervous system "slows things down" - correct answerparasympathetic

what nervous system has terminations in all level of the heart - correct answersympathetic nervous system

stimulation of the sympathetic nervous system causes what? - correct answervasoconstriction in general and increases the heart

rate

what nervous system is important in maintaining blood pressure - correct answersympathetic

vasomotor is controlled by the - correct answersympathetic nervous system

the vasomotor does what - correct answercontrols the diameter of the blood vessels

baroreceptors regulate what function - correct answerblood pressure with positional changes

the sympathetic or adrenergic effects of the autonomic nervous system involve what - correct answertwo effects A and B- these

effect several tissues and organs

Alpha effect is what (only one alpha) - correct answervasoconstriction

Beta effect is what( two beta categories) - correct answerseen in bigger organs, heart and lungs

Beta 1 activity is where - correct answerheart related functions- such as increased heart rate and strength of contraction

Beta 2 activity is where - correct answerpulmonary function of bronchiolar dilation (lungs)

Parasympathetic stimulation causes what - correct answerincreased activity of digestive tract and stimulates production of saliva

and pharyngeal secretions. (atropine or Robinul can counteract stimulations)

Automaticity - correct answerheart pumps on its own

Heart has four chamber- what are they - correct answerleft atrium, right atrium, left ventricle, right ventricle

Where does the left atrium receive blood from - correct answerfrom the lungs, via the pulmonary vein- oxygen rich blood

Where does the right atrium receive blood from - correct answerfrom the peripheral (body's) circulation and is oxygen poor

the ventricles receive blood from where - correct answerthe atria

Ventricle anatomy - correct answerthicker walls

larger chambers

left ventricle is the thickest m.

Where does the right ventricle send blood - correct answerdeoxygenated blood to the lungs

Where does the left ventricle send blood - correct answeroxygenated blood to the body/ peripheral circulation

What are the three sources the right atrium receives blood - correct answer above: superior vena cava below: inferior vena cava inside the heart m.: coronary sinus the blood in veins are considered what - correct answer oxygen poor blood vessels leading AWAY from the heart are - correct answer arteries blood vessels leading TO the heart are - correct answer veins Flow of Blood through the heart - correct answer 1. right atrium fills with blood

contracts- tricuspid valve
right ventricle fills with blood
contracts- closes tricuspid valve/opens pulmonary valve
blood goes through pulmonary artery to the lungs
pulmonary veins returns blood to left atrium
contracts-mitral valve
left ventricle fills with blood
Contracts- forces blood through aortic valve into aorta and then the peripheral circulation. closure of the four valves prevents back flow. if valve is damaged then this will be a - correct answer heart murmur or mitral valve prolapse most heart problems are because of - correct answer faulty or reduced coronary circulation- the hearts own circulatory system reduced oxygen supply weakens the heart this condition is called - correct answer ischemia what results from ischemia - correct answer angina pectoris- chest pain poor circulation can also cause - correct answer myocardium infarction arteries can either ________ or _________ - correct answer vasodilation or vasoconstriction diastolic phase is during what part of the blood flow - correct answer when the ventricles are relaxed diastolic pressure measures what - correct answer the pressure in the arteries during the relaxation of the ventricles systolic phase is what part of the blood flow - correct answer when the ventricles contract systolic pressure measures what - correct answer the pressure in the arteries during the contraction of the ventricles cardiac cycle - correct answer 60 - 100 beats/minute bradycardia - correct answer less than 60 tachycardia - correct answer greater than 100 sinoatrial node (SA) - correct answer located right atrium pacemaker of the heart rhythms caused by the SA node are called what - correct answer sinus rhythms ectopic pacemakers occur when - correct answer when the SA node fails- they will be produced and take over as the pacemaker the impulse from the SA Node travels to where - correct answer the atrioventricular node (AV) after the AV node is stimulated where does the impulse go - correct answer bundle of His where does the impulse go after the bundle of His - correct answer purkinje fiber system the Purkinje system does what with the impulse - correct answer fibers that branch into the right and left ventricles and the ventricles will contract does the AV node speeds up or slows down the impulse - correct answer slows down Stroke Volume - correct answer 60 mL of blood (30 mL = 1 oz) amount of blood pumped by the left ventricle in one beat cardiac output - correct answer total amount of blood pumped by the left ventricle in one minute

tidal volume - correct answer amount of air inhaled and exhaled

average 500 cc
350 cc of air actually reached the alveoli respiratory involuntary function due to - correct answer center located in medulla oblongata Normal adult respiration - correct answer 12 - 16 respirations/min at rest
