Cardiovascular system 2 Flashcards
The groove between the atria and the ventricles dividing the top, half and the bottom half
Atrioventricular groove
The blood supply to the heart
Coronary circulation
— provides blood supply to the heart while — drains Venous blood from the heart
- coronary artery
- coronary vein
The groove that divides the right, and left ventricles looping from the anterior to the posterior
Interventricular grooves
The 2 main blood vessels of the right coronary artery?
- The right marginal artery
- The posterior interventricular artery
The 2 main blood vessels of the left coronary artery?
- The left interior interventricular artery
- The circumflex artery
What is coronary dominance
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.
A large vein on the posterior aspect of the heart in the atrioventricular groove
Coronary sinus
The joining of two blood vessels to create a connection
Anastomosis
( serves as a backup mechanism)
— cardiac vein travels along the right margin of the right ventricle in the atrial ventricular groove.
Small cardiac vein
— cardiac vein travels along the left side of the anterior interventricular groove.
Great cardiac vein
Small veins that are on the surface of the heart. They drain directly into the right atrium because of their location.
Anterior cardiac vein
(they are the only vein of the heart that do not drain into the coronary sinus first)
The first branch of the arc of aorta coming up is the ? and it splits into two arteries named ?
- Right brachiocephallic trunk
- right subclavian artery (goes up to the neck)
Right common carotid artery (provides the upper limbs with blood supply)
The second branch of the arch of Aorta is the? and the third branch is the?
- left common carotid
- Left subclavian artery (which goes to the upper extremities)
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?
- Small cardiac vein
- Left marginal vein
- Coronary sinus
- middle cardiac vein
- Great, cardiac vein
The superior gene cava branches into the?
-Left and right brachiocephalic vein (which branches into the left and right subclavian vein and internal jugular vein)
Component of the nervous system that provides innovation to the heart
- Intrinsic
- Extrinsic
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
Sinoatrial node
– Node informs the atria to contract while – node send impulses to the ventricles to contract
- sinoatrial node
- Atrioventricular node (via the Interventricular branches?
What are nerves within the actual muscular walls of the heart?
Purkinje fibers
A muscular bond of tissue, extending between the interventricular septum and the anterior papillary muscles containing purkinje fibers
SeptoMarginal band
– Innervation of the heart comes from the sympathetic and parasympathetic nervous system
- extrinsic
The sympathetic information coming down to the heart comes from?
The spinal code between T2 to T4
The cranial nerve that comes from the brain stem
Vagus nerve
