Name the exit(s) from the Right Atrium and where does the blood go.
1- Tricuspid valve- opens to the right ventricle
Name the entrance(s) to the Right Atrium, and where does the blood come from.
3- inferior vena cava (below the heart), superior vena cava(above the heart), coronary sinus(from the heart)
Name the exit(s) from the Right Ventricle and where does the blood go.
Pulmonic Valve is the door, 2 pulmonary arteries (right and left) are the passage ways to the lungs- the RV outflow.
Name entrance(s) to the Right Ventricle and where does the blood come from.
1- tricuspid valve, blood comes from the right Atrium, or RV -inflow
Name exit(s) from the Left Atrium and where does the blood go.
1- mitral valve, blood flows into the left ventricle.
Name entrance(s) to the Left Atrium and where does the blood come from.
4 pulmonary veins- 2 superior right and left 2 inferior right and left, blood comes from the lungs
Name exit(s) from the Left Ventricle.
3- Blood leaves the LV through the Aortic valve, then to the Brachiocephalic artery, left common carotid artery, left subclavian artery -LV outflow
Name entrance(s) to the Left Ventricle where does the blood come from.
1- mitral valve - blood comes from the left atrium LV inflow
What is the most common defect in infants?
Heart defects, because the heart develops at 21 days Mother may not know she is pregnant and maybe drinking and smoking.
Why do we see damage occur in the Brachiocephalic artery.
More congestion because of the amount and pressure of the blood flow, more plaque build up here.
If plaque build up occurs in the Brachiocephalic artery what happens.
Less blood flow to the right side of the brain (stroke)
Describe the location of the heart in the body.
Central 1/3 (third) of the chest cave
1/3 (30 percent) of the heart is behind the sternum 2/3 (70 percent) is in the left chest
What is significant about the Left Atrium appendage?
It is a potential site for thrombosis formation.
When a heart transplant is preformed do they only transplant a new heart, explain.
No -they transplant the whole unit (heart and lungs) Veins and arteries cannot be attached to a new heart.
What is the most common birth defect of the heart?
V.S.D. Ventral Septum Defect, Symptoms are detected right away and treated.
What is V.S.D. Ventral Septum Defect? Explain the symptoms.
The inter ventricular septum has a hole in it, i.e. a hole between the two ventricles. Symptoms are detected right away because of the pressure difference, LV (120 mm HG) and the RV (25 mm HG)
What is A.S.D. Ventral Septum Defect?
The inter aterial septum has a hole in it, i.e. a hole between the two atriums.
Do infants with A.S.D. (Ventral Septum Defect) show symptoms? explain.
No, Symptoms are not exhibited because of the low pressure difference the LA (10 mm HG) and the RA (5 mm HG) So A.S.D. is most commonly found in adults.
Describe the left border of the heart, what you can see with ultra sound.
LV & LA left atrium, left ventricle
Describe the inferior border of the heart, what you can see with ultra sound.
RA, RV, LV right atrium, right ventricle, left ventricle
Describe the superior border of the heart, what you can see with ultra sound.
Aortic vessels and pulmonary vessels
Name the leaflets of the tricuspid valve.
3 leaflets: longest -Septal, medium -anterior, smallest -posterior
Name the leaflets of the pulmonary valve.
3 semi circles leaflets all the same size, Right, Left and Posterior
