The three forms of energy associated with blood are kinetic energy, potential energy, and thermal energy. Here is a description and example of each:

  1. Kinetic Energy: This is the energy associated with the motion of blood as it flows through the circulatory system. The faster the blood moves, the more kinetic energy it possesses.

    • _Example_: When the heart pumps blood through the arteries, the blood gains kinetic energy as it moves rapidly from the heart to various parts of the body.

  2. Potential Energy: This is the energy stored in the blood due to its position in the gravitational field, particularly in relation to the height of the blood in the body. Blood in the upper parts of the body, such as the head, has more potential energy compared to blood in the lower parts.

    • _Example_: Blood in the aorta at the level of the heart has potential energy due to its elevation above the feet. This potential energy helps drive the blood flow downwards through the body.

  3. Thermal Energy: This is the energy related to the temperature of the blood. Blood carries heat throughout the body, helping to regulate body temperature.

    • _Example_: When exercising, the muscles generate heat, which is absorbed by the blood. The increased thermal energy in the blood is then distributed throughout the body, helping to maintain a stable internal temperature.

In summary, blood exhibits kinetic energy through its movement, potential energy due to its position in the body, and thermal energy as it helps regulate body temperature.

Question 17 (1 point) Professor Cook is lecturing on the importance of the myelin sheath. He told the class that - a) myelin is the only structure that can prevent action potentials from traveling the wrong direction. b) the fatty nature of the myelin speeds up the action potential down the length of the axon c) the fatty nature of myelin provides storage for key nutrients for the neuron d) myelin increases the strength of the action potential
