Answer:

As blood travels through the body, oxygen is used up, and the blood becomes oxygen poor. Oxygen-poor blood returns from the body to the heart through the superior vena cava (SVC) and inferior vena cava (IVC), the two main veins that bring blood back to the heart.

The outside temperature is 35C, what is the temperature in K? K=274.15+ c.

krek1111 [17]

The answer is 308 K.

The formula is C + 273.15 = K

this meaning the formula for this problem would be 35 + 273.15 = 308.15.

Out of all the option choices that would be rounded to 308K.
