The superior vena cava returns most of the venous blood from the heart to the right atrium.
The whole return of systemic venous blood goes to the right atrium. Either the inferior vena cava or the superior vena cava receives the majority of the blood. The superior vena cava receives systemic venous circulation, which includes blood from the head, neck, chest, shoulders, and upper limbs, from above an imaginary line drawn at the level of the diaphragm.
Most of the body above the diaphragm is drained via the superior vena cava. The axillary vein, which originates in the axillary area, goes through the body wall to produce the subclavian vein on both the left and right sides. The brachiocephalic vein is created when it unites with the external and internal jugular veins of the head and neck.

Yes, everything has matter
Which coefficients balance this equation? _CH4 + _O2 -> _CO2 + _H2O A. 1, 1, 1, 1 B. 1, 1, 2, 1 C. 1, 2, 1, 2 D. 2, 1, 2, 1
ICE Princess25 [194]
C. 1,2,1,2
1 CH4+ 2 O2= 1 CO2+ 2 H20.
when balancing, you need to make sure that each side has the same number of each atom. The reason for this is to abide by the law of conservation of mass; essentially you can't have more or less than you put in the equation.
When you put the coefficients of C. into the equation you have a total of 2 carbon atoms on each side, 4 hydrogen atoms, and 4 oxygen atoms.
