Blood vessel identification (NOVAK) Flashcards
Why is the heart considered a dual pump?
It pumps blood to the pulomonary system and then back to the heart where the heart will then pump the blood through systemic circuit.
- Pulmonary circuit
- Systemic circuit
The base of the heart is located at the _____.
A. top
B. bottom
A. top
Base of heart = top
Apex of heart = bottom
Which of the following is the Anterior and inferior part of the heart that points to the left hip?
A. base of heart
B. apex of heart
B. apex of heart
Base of heart = posterior superior
Apex of heart = anterior and inferior
Which of the following is at the level of the fifth left intercostal space?
A. base of heart
B. apex of heart
B. apex of heart
Describe where the heart is located in the body:
The heart lies on the diaphragm, posterior to the sternum, in the mediastinum
Discuss blood flow through the heart: (16 steps)
Blood travels
- through systemic veins —> superior and inferior venae cavae and coronary sinus
- Right atrium
- Tricuspid valve (right AV valve)
- Right Ventricle
- Pulmonary semilunar valve
- Pulmonary trunk and arteries
- Gas exchange in lungs
- Pulmonary veins
- Left atrium
- Bicuspid valve / Mitral valve (left AV valve)
- Left ventricle
- Aortic semilunar valve
- Aorta Systemic arteries
What is another name for bicuspid valve?
Mitral Valve (left AV valve)
What is another name for Right AV valve?
Tricuspid valve
