heart anatomy

Cornary arteries and veins are the blood vessels that supply blood and carry away away.  

STRUCTURE
FUNCTION
DEOXY/OXY BLOOD
LEFT ATRIUM
-collects oxygen-rich blood from the lungs then forces through the mitral valve into the left ventricle
OXY
LEFT VENTRICLE
-largest and strongest chamber, wall is only half an inch thick and it pushes blood through aorta valve into the body
OXY
RIGHT ATRIUM
-collects oxygen-poor blood returning coming back from the body and then it forces it through the tricuspid valve then into the right ventricle.
DEOXY
RIGHT VENTRICLE
- collects oxygen-poor blood from the right atrium and then forces it through the pulmonary valve then into the lungs
DEOXY
PULMONARY ARTERY
-carry blood from the heart to the lungs to pick up oxygen
DEOXY
AORTA
- the largest artery carries oxygen-rich blood from the heart to the rest of the body
OXY
PULMONARY VEINS
-carry oxygen-rich blood from the lungs back to the heart
OXY
SUPERIOR VENA CAVA
-oxygen-poor blood from the upper body returns to the heart through the superior vena cava
DEOXY
INFERIOR VENA CAVA
-oxygen-poor blood from the upper body returns to the heart through the inferior vena cava
DEOXY
ATRIOVENTRICULAR VALVES (Mitral & Tricuspid)
tricuspid controls blood flow from the right atrium to the right ventricle and mitral controls flow from the left atrium to the left ventricle
Deoxy/oxy
CHORDAE TENDINAE
 - bring right ventricular walls closer together during contraction.  -pull the AV Valves open during atriole systole
Left oxy
Right deoxy
SEMI LUNAR VALVES (Pulmonary & Aortic)
-pulmonary valve control blood flow from right ventricle to the pulmonary arteries and aortic valve controls blood from left ventricle to aorta
 deoxy/oxy
SEPTUM: separates left from right- /
