Blood passes through the bicuspid valve and enters the left ventricle.
When blood leaves the lungs through the pulmonary veins, it returns to the heart and enters the left ventricle.
The blood enters throught the heart throught the right and left atria. As the heart contracts, blood flows into the ventricles and then out from the ventricles.
alve
Through the vena cava. Blood enters the heart at the right atrium when from the systemic circulation. It Gets here through the superior and inferior vena cava and the coronary sinus. From the pulmonary circulation it enters the left atrium from the pulmonary vein.
Through the inferior and superior vena cavaThe left atria of the heart is where oxygenated blood enters, it is then pumped to the left ventricle and then to the rest of the body thru the systematic circuit. The heart is separated by the septum, which separates oxygenated and deoxygenated blood.
Blood returning from systemic circulation enters the heart at the right atrium. Blood from the pulmonary circulation enters the left atrium.
When blood leaves the lungs through the pulmonary veins, it returns to the heart and enters the left ventricle.
Oxygen-poor blood enters the heart through the right atrium
Oxygenated blood enters the left side of the heart (atria) via the pulmonary veins
De-oxygenated blood is dark red. Oxygenated blood is bright red. Both enter the heart- the former enters the right heart; the latter enters the left heart.
Right atrium
Blood returning from the body systemic circulation first enters which chamber of the heart?
The blood enters throught the heart throught the right and left atria. As the heart contracts, blood flows into the ventricles and then out from the ventricles.
The pure blood after circulation leaves the heart and enters into the aorta or the aortic arch. Then from here it circulates in the whole body for the exchange of materials. The impure blood, coming from the superior and inferior vena cava, circulates in the heart and enters into the lungs through the pulmonary artery for its purification.
Blood first leaves the heart of a fish and enters the gills for oxygenation. From the gills, oxygenated blood is transported to the rest of the fish's body through arteries.
Blood enters the heart through the Inferior Vena Cava from all the regions of the body below the heart
Deoxygenated blood enters the heart via the superior and inferior vena cava.
