The first one is C. heart and the other would be the Heart chambers cause the heart is the one that pumps blood to the body it also has four, Two Atriums and two ventricles 

the Atrium is the upper, the right Atrium receives deoxygenated blood from the veins of the body. as the left Atrium receives oxygenated blood

now the Ventricles each two main chambers of the heart, left and right 
they are what pump the blood one pumps blood in and the other pumps it out.
hope that helps :)

Sarah went to measure the output of urine for Mr. Jones. In the urinal, it read 630mL. Sarah charted 16oz. Is Sarah’s calculatio
Taya2010 [7]

Answer:

Sarah's calculation isn't correct.

Explanation:

Both milliliters (ml) and ounces (oz) are units used to measure the volume of fluid. One ounce is about 29.6 milliliters. If we multiply this by 16, we'll get about 473ml, which doesn't fit Sarah's original measurements. 473ml is obviously way less than 630ml. Her calculation would be correct if she wrote down 21.3oz (630ml ÷ 29.6 = 21.3oz).
