Quiz - Cardio

Question 1

Why/how does the venous blood move in the body?

Answer 1

Venous Pump

Question 2

Who controls the local vasomotor reflexes

Answer 2

Autonomous in the that place, not controlled by the brain

Question 3

Carotid barroreflexor detects low blood pressure, is the response sympathetic

Answer 3

Sympathetic, you want to contract

Acidotic leads to?

Answer 4

Tachycardia – pump more blood through lungs to expel more CO2

Question 5

What kind of feedback received by the body when you have excited emotions?

Answer 5

Emotions is cortex, brain, not automatic

Question 6

What is the cardiac output?

Answer 6

• Def: amount of blood pushed out per unit of time

- Stroke volume – frequency (heartrate)

Question 7

Definition of Murmur

Answer 7

• Cardiac murmur is the sound produced by the rush of blood around a heart abnormality (intracardiac irregularity)
• Could be a bunch of different branches

Question 8

What happens during isovolumetric ventricular contractions?

Answer 8

Volume stays the same, but the pressure is increasing because of contractions in the ventricles (the valves haven’t opened yet)

Question 9

What is the QRS

Answer 9

Ventricles depolarization

Question 10

Ventricular repolarization is which part of the ECG wave?

Answer 10

T waves

Question 11

Duration of QRS?

Answer 11

Under O.1

Question 12

QRS’s structure is?

Answer 12

It’s a spike, ventricles depolarizing and atriums polarizing

Question 13

Hepatic portal system?

Answer 13

• Is the gastrointestinal areas (spletnik area) veins going through the liver before going to the inferior vena cava
• The liver does not ‘filter’, it detoxifies and metabolizes the stuff in the blood

Question 14

Name of the artery where we normally check for a pulse?

Answer 14

Radial

Question 15

Left common iliac artery is a branch of the?

Answer 15

Abdominal aorta

Question 16

Hypoxia triggers vasodilation into the lungs. True or False?

Answer 16

False, it vasoconstricts – therefore, pulmonary hypertension

Question 17

Endothelium covers the valves in the veins. True or False?

Answer 17

True, it covers everything in the vessels and heart

Question 18

Diastolic pressure gives necessary push for the blood to return to the right side of the heart. True or False?

Answer 18

False, there is no pressure in the venous system

Question 19

Perkinje Fibers intervate (electrify) the valves. T/F?

Answer 19

False, the valves are not electrified, they are passive, not mechanical flaps

Question 20

Who innervates the myofibers of the atria?

Answer 20

Interatrial fibers, interatrial bundle

Question 21

How do parasympathetic nerves get sent to the plexus?

Answer 21

Vagus nerve

Question 22

Where is the cardiac plexus

Answer 22

By the aortic arch, NOT IN, BY (beside)

Question 23

What is the name of final branches of the bundle of HIS?

Answer 23

Purkinje Fibers

Question 24

How many branches of the bundle of HIS before fibers?

Answer 24

2, on the right and left

Question 25

What happens to the pulmonary valve vein when the tricuspid valve is open?

Answer 25

- Nothing, it is closed. | - When the AV valves are open, the SL valves are closed

Question 26

What is the normal sequence of the heart contraction?

Answer 26

Atria contracts then the ventricles

Question 27

Chordae Tendonae is?

Answer 27

The tendons (fibers) holding down the boarders of the leaflets of the AV valves to the papillary muscles

Question 28

Trabeculae carnae

Question 29

Endothelium is what type of cell?

Answer 29

Non keratinized simple squamous cells

Question 30

How many pulmonary arteries do we have?

Answer 30

0, they’re veins – NOT ARTERIES
