Study Notes
- Main function of the circulatory system: transporting oxygen and nutrients.
- Pressure exerted by blood against vessel walls is called blood pressure.
- Laminar blood flow is smooth and follows parallel layers.
- Blood pressure is measured in millimeters of mercury (mmHg).
- A key characteristic of laminar blood flow in large arteries is a parabolic velocity profile.
- Normal resting heart rate for an adult: 60-100 beats per minute.
- Wall elasticity primarily influences the propagation speed of the blood pressure wave.
- Turbulent blood flow increases energy loss in circulation.
- The second law of thermodynamics states that in a thermodynamically isolated system there exists a state function that does not decrease over time.
- Zero on the Kelvin scale (-273.15 °C = 0 K) is the lowest theoretically possible temperature where all molecular vibrations cease (absolute zero).
- Entropy (S): The false statement is: The cause of spontaneous reactions (processes) is the tendency of energy and matter to decrease the state of disorder.
- Evaporation is a change from liquid to gas.
- The first law of thermodynamics states that the total energy in a closed system remains constant.
- According to the second law of thermodynamics, entropy in an isolated system increases over time.
- Heat transfer through direct contact between molecules occurs through conduction.
- Turbulent blood flow increases energy loss in circulation.
