Cardiovascular system 2

Question 1

The groove between the atria and the ventricles dividing the top, half and the bottom half

Answer 1

Atrioventricular groove

Question 2

The blood supply to the heart

Answer 2

Coronary circulation

Question 3

— provides blood supply to the heart while — drains Venous blood from the heart

Answer 3

• coronary artery
• coronary vein

Question 4

The groove that divides the right, and left ventricles looping from the anterior to the posterior

Answer 4

Interventricular grooves

Question 5

The 2 main blood vessels of the right coronary artery?

Answer 5

• The right marginal artery
• The posterior interventricular artery

Question 6

The 2 main blood vessels of the left coronary artery?

Answer 6

• The left interior interventricular artery
• The circumflex artery

Question 7

What is coronary dominance

Answer 7

Coronary dominance is where the posterior interventricular artery comes from. This can be from the left or from the right.
Majority of the population are right coronary dominant.

Question 8

A large vein on the posterior aspect of the heart in the atrioventricular groove

Answer 8

Coronary sinus

Question 9

The joining of two blood vessels to create a connection

Answer 9

Anastomosis
( serves as a backup mechanism)

Question 10

— cardiac vein travels along the right margin of the right ventricle in the atrial ventricular groove.

Answer 10

Small cardiac vein

Question 11

— cardiac vein travels along the left side of the anterior interventricular groove.

Answer 11

Great cardiac vein

Question 12

Small veins that are on the surface of the heart. They drain directly into the right atrium because of their location.

Answer 12

Anterior cardiac vein
(they are the only vein of the heart that do not drain into the coronary sinus first)

Question 13

The first branch of the arc of aorta coming up is the ? and it splits into two arteries named ?

Answer 13

• Right brachiocephallic trunk
• right subclavian artery (goes up to the neck)
  Right common carotid artery (provides the upper limbs with blood supply)

Question 14

The second branch of the arch of Aorta is the? and the third branch is the?

Answer 14

• left common carotid
• Left subclavian artery (which goes to the upper extremities)

Question 15

In vasculature of the heart,
- The right marginal artery travels with the?
- The left marginal artery travels with the?
- The circumflex artery travels with the
- The posterior interventricular artery travels with the?
- the anterior Interventricular artery travels with the?

Answer 15

• Small cardiac vein
• Left marginal vein
• Coronary sinus
• middle cardiac vein
• Great, cardiac vein

Question 16

The superior gene cava branches into the?

Answer 16

-Left and right brachiocephalic vein (which branches into the left and right subclavian vein and internal jugular vein)

Question 17

Component of the nervous system that provides innovation to the heart

Answer 17

• Intrinsic
• Extrinsic

Question 18

The bundle of nerve cell that is located in the right atrium, considered to be the pacemaker of the heart and provide branches to the atria to contract

Answer 18

Sinoatrial node

Question 19

– Node informs the atria to contract while – node send impulses to the ventricles to contract

Answer 19

• sinoatrial node
• Atrioventricular node (via the Interventricular branches?

Question 20

What are nerves within the actual muscular walls of the heart?

Answer 20

Purkinje fibers

Question 21

A muscular bond of tissue, extending between the interventricular septum and the anterior papillary muscles containing purkinje fibers

Answer 21

SeptoMarginal band

Question 22

– Innervation of the heart comes from the sympathetic and parasympathetic nervous system

Answer 22

• extrinsic

Question 23

The sympathetic information coming down to the heart comes from?

Answer 23

The spinal code between T2 to T4

Question 24

The cranial nerve that comes from the brain stem

Answer 24

Vagus nerve

Question 25

The network of nerves from the sympathetic and parasympathetic system merge together on top of the heart to create the?

Answer 25

Cardiac plexus
