Answer:
<u>Cardiac output = ejection volume X heart rate
</u>
Explanation:
CARDIAC EXPENSE, is the amount of blood that the ventricles propel every minute.
<u>
Cardiac output = ejection volume X heart rate
</u>
<u />
Cardiac output is modified by changing the volume that is expelled in each beat (<em>ejection volume or systolic volume</em>), or by changing the heart rate.
<em>The heart covers a wide range of blood flow demands. Cardiac output can range from 5 to 30 L / min, depending on the activity of the organism.</em>

Answer: B) Contusions are damaged skin and blood vessels that form red or blue discolorations of the skin. Hematomas are ruptured blood vessels beneath the skin that bleed enough to form bumps and swelling under the skin.
Explanation:
Contusion or bruising results when the blood vessels are broken and the blood is leaked out and blood can be observed at the place where the injury actually occurred. The hematomas are the proof of injuries which are caused by the same reason as that of contusion but are larger than contusions. The contusions are dark red to brown in starting then turns blue to pale yellow on recovery. The hematomas are formed when large number of blood vessels are affected associated with swelling and bumps. Thus the skin appears raised.
