Answer:
Q1. The chief function of the lymph nodes is to
1. They filter lymph and assist the immune system
2. Lymph is a clear fluid that comes from blood plasma that exits blood vessels at capillary beds.
3. This fluid becomes the interstitial fluid that surrounds cells.
Q2.
Heart sounds are created from blood flowing through the heart chambers as the cardiac valves open and close during the cardiac cycle. Vibrations of these structures from the blood flow create audible sounds — the more turbulent the blood flow, the more vibrations that get created. The same variables determine the turbulence of blood flow as all fluids. These are fluid viscosity, density, velocity, and the diameter of the column through which the fluid is traveling.
Q3.
