Heart Structure Quiz Flashcards
Practice labeling heart image
- Tricuspid valve
- Superior and Inferior Vena Cava
- Right atrium and ventricle
- Left atrium and ventricle
- Pulmonary valve
- Trunk of pulmonary artery
- Left pulmonary artery and right pulmonary artery
- Left and right pulmonary veins
- Bicuspid/ mitral valve
-Aorta/ Aortic arch
- Chordae tendinae
- Interventricular septum
- Papillary Muscles
- Coronary vessels
- Circumflex artery
- ductus arteriorisus
- Apex
Largest artery in the body that delivers blood to the body
Aorta
How many valves does the heart have?
4
Ventricle vs Atrium
Ventricle is the bottom half of the heart and atrium is the top half
What to remember about right and left sides of body?
Remember it is patient’s left and right
Layers of the heart
(outermost to innermost)
Epicardium
myocardium
Endocardium
What is the thickest part of the heart?
Left ventricle
Fluid filled sac that covers the heart
Pericardium
Interventricular Septum
Prevents oxygenated and deoxygenated blood from mixing
Vein vs Artery
Include color and the one exception
Vein- blood goes towards heart(blue)
Artery- blood goes Away from heart(red)
ONLY EXCEPTION IS PULMONARY ARTERY AND VEIN ARE SWITCHED IN COLOR)
Why is the human heart called a double loop?
blood passes through the heart twice in a complete circuit of the body: once on its way to the lungs (pulmonary circulation) and once on its way to the rest of the body (systemic circulation), effectively creating two distinct loops within the circulatory system
Practice drawing heart blood flow
Striations
Lighter and so many more than intercalated discs
Intercalated discs
Thicker and darker stripes. They connect the individual cells.
What does a nuclei look like in cardiac muscle?
It will be roundish, ovalish
Which side of the heart is bigger?
Left side is much larger
Which side of the heart is red?
The left side plus the pulmonary veins
Which side of the heart is blue?
The right side plus the pulmonary arteries
Arteriole
Small artery
Venule
Small vein
Capillary
Smallest vessel where we are actively exchanging gases
Papillary muscles
Pull on heart strings(chordae tendineae) to open and close valves
How does blood flow when it comes to arterioles, venules, and capillaries and what type of blood is it?
It goes arteries, arterioles, capillaries, venules, veins
Arteries and arterioles(for pulmonary only) are blue. Venules and veins(for pulmonary only) are red. Capillaries are purple(red and blue).
Systemic Arteries and arterioles are red. Venules and veins are blue. Capillaries are purple(red and blue). Systemic comes after aorta
