The human circulatory system is composed of three things they are the heart blood
vessels, a sound a heart beats in a minute is called heart rate, and the heartbeat
is the indication for the health status of an individual. In 1816, French physician
René Laennec invented the stethoscope. He used a paper paper only status to see
that in the picture, Rene Lenek was listening to the heartbeat using a pepper roll.
One cardiac cycle is equal to one contraction and one relaxation of atria and
ventricles. The whole process is completed in approximately 0. 8 seconds.
The lymphatic system in our body doesn't need a specific transport system but
multicellular organisms do need a special transport system to get around the body.
Platelets are converted into thrombin by the action of thrombokinesis material
insoluble fibrin. The thrombin then fuses with the plasma membrane to create a
blood clot.
