Which of the following is the formula for power?
\(P = {w \over t}\) |
|
\(P = w t\) |
|
\(P = {\vec{w} \over t}\) |
|
\(P = \vec{w}t\) |
Power is the rate at which work is performed or work per unit time: \(P = {w \over t}\) and is measured in watts (W).
Which of these does not contain oxygenated blood?
left ventricle |
|
right atrium |
|
aorta |
|
pulmonary vein |
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.
