Heart Flashcards
What is the heart located (cavity)
Thoracic cavity or in mediastinum
If the heart was divided into 4 cubes, then what are cubes 1 and 3 for? What are cubes 2 and 4 for? What do they do?
1 and 3 are called atria
2 and 4 are called ventricles
Atria are receivers and ventricles are pumps
If the sac or fluid around the heart is enfected, what is it called?
Pericarditis
If there is inclination of infection of heart muscle, what is it called?
Myocarditis
What are the three layers to the heart?
Outside layer; apicardium
Middle layer: myocardial
Inner layer: endocardium
What is the outermost layer of the sac that goes around the heart?
Fibrous
Which part of heart goes into the lungs?
Right ventricle
What are pulmonary veins?
Blood retuning back to heart from the lungs
I’m the heart, what are valves? Which are present?
Something that opens up before putting in blood
Atrio ventricular valves (located in the middle of receiver and pumps. And semilunar which lead out of heart
Which valve (blood transporter) sits between left atria and left ventricle?
Mitral
What are the 3 major vessels to return blood?
Superior venacara
Inferior venacara
Coronary vein
What is for storage of blood (reservoir)
Auricle
What prevents prolapse?
Cordae tendonae
How does a valve work?
The cordae tendonae connect capillary muscle to valve. Blood goes from receiver to pump through ventricle. Creates “lub” sound
What anchors the chordate tendonae to the heart?
Papillary muscle
What is the aorta? What are the three parts of aorta?
The aorta is largest artery which carry’s blood to the circulatory system.
Ascending aorta
Aortic arch
Descending aorta
What is the first branch of artery coming off of aorta?
Coronary
Which is the first branch of artery coming off aorta?
Coronary
Which artery leads to right side of body?
Brachiocephalic
Which is true about arteries?
Always lead away from the heart
What holds aortic arch in place
Ligamentum arteriosum
