vena cava
It enters the heart from the head and upper body via the Superior Vena Cave. The blood from the lower body travels through the Inferior Vena Cave.
The heart has upper and lower chambers.
The heart is divided into four compartments. The two upper portions where blood enters the heart from the body and lungs are the atria. Deoxygenated blood enters the right atrium, and oxygenated blood from the lungs enter the left atrium.
The upper heart valves are called atriums, and the lower heart valves are called ventricles.
lower part upper part is called Ariom i think
blood used by the body enters the right atrium
The ventricles are the lower chambers of the heart. The atria are the upper chambers.
The heart is divided into four chambers. The two bottom heart chambers are called the ventricles. The upper chambers are the atrials.
The lower chambers of the heart are the ventricles. In contrast, the upper chambers are the atria.
The ventricles are the lower chambers of the heart. The atria are the upper changes.
The AV valves separate the upper and lower chambers of the heart. The bicuspid valve is on the left, and the tricuspid on the right.
The lower quartile is the second smallest and the upper quartile is the fourth smallest (second largest).
