Explanation:
Answer:
decreased body temperature
Explanation:
Muscles also need oxygen to function properly. Given that blood flow must be maintained at high levels to supply oxygenation and muscle substrates, mechanisms have been found to facilitate this process. Among the processes that facilitate the transfer of oxygen to tissues, we can mention lowering blood pH, increasing carbon dioxide and increasing exercise.
Lower body temperature, in turn, makes it difficult to transfer oxygen to tissues, causing fatigue, pain and other problems.

Answer: Option D
During isovolumetric contraction blood is flowing from the ventricles into the aorta and pulmonary arteries.
Explanation:
Isovolumetric contraction is an occurrence that happen in the systole where the ventricle contracts with no change in volume. Isovolumetric contraction causes the left ventricles pressure to rise above the atrial pressure which shut the mital valve and cause the first heart sound. When the pressure rises in the left ventricle, it contracts and pump blood to the aorta and pulmonary arteries. The ventricles continue to contract and blood continue to flow to the aorta and pulmonary arteries in the systole.
