The process of diffusion allows __________ to exchange oxygen, carbon dioxide, nutrients, and waste between blood and the body's cells.
red blood cells |
|
veins |
|
capillaries |

The formula to convert from F° to C° is:
\(C° = {5 \over 9} (F° - 32)\)
plugging in our values gives:
\(C° = {5 \over 9} (50 - 32)\)
\(C° = {5 \over 9} (18)\)
\(C° = {90 \over 9}\)
\(C° = 10\)
Which of these represents the path of blood flow through the heart?
right atrium → left ventricle → lungs → left atrium → right ventricle |
|
right atrium → right ventricle → lungs → left atrium → left ventricle |
|
left atrium → left ventricle → lungs → right atrium → right ventricle |
|
left atrium → right ventricle → lungs → left atrium → right ventricle |
To provide oxygen to the body, blood flows through the heart in a path formed by the right atrium → right ventricle → lungs → left atrium → left ventricle → body. When blood enters the right side of the heart it is deoxygenated. It enters the left side of the heart oxygenated after traveling to the lungs.
