the ventricles
or arteries
Atria receive blood into the heart and ventricles "discharge" it from the heart
the atria
Because they pump the blood out of the heart
The question really contradicts itself. The superior chambers are the atria, but they are receiving chambers. The left ventricle is a discharging chamber, but is inferior. I would go with the left ventricle. I'm working on the same paper in anatomy. Ask your teacher to be completely sure.
i think it is 4 chambers in the Human Heart
4 heart chambers
No. The lower chambers of the heart are called the ventricles. The atria are the top chambers of the heart.
Their are 2 heart chambers.
There are 4 chambers to the heart.
The bird's heart has 4 chambers.
The human heart has four chambers connected by valves. We have 2 smaller chambers on the upper half of our heart and two larger chambers on the bottom of our heart. The smaller chambers are called atria; the larger chambers are called ventricles. So we refer to these chambers as right and left atrium, and right and left ventricle.
Clams have the most complex heart of the mollusks, with 3 chambers.
