TRANSPORTATION is a life process In which a substance synthesized observed in one part of the organism is carried to other parts of the body. TRANSPORTATION IN ANIMALS Before learning the mechanism involved in transportation, let us look at some basic terms to be used in transportation… Circulatory System : The circulatory system is responsible for transport of various substances  in human beings.

WORKING OF HEART ❤ The muscular organ which is located near the chest slightly towards the left in the thoracic region.The heart is the main pumping organ of the body. It makes the sound of LUB-DUB due to the closing and opening of valves present in the heart. It is made up of cardiac tissue. The human heart is divided into four chambers which are involved in the transportation of oxygenated and deoxygenated blood. The upper two chambers are called atria whereas the lower two chambers are called ventricles. It is surrounded by a tough two layered sac called pericardium .  The pericardial fluid is secreted in pericardial cavity between pericardium and heart which reduces the friction between heart wall and surrounding tissues when heart is beating. Height is divided by Septa into two halves:  right and left.   Each have consists of two communicating chamber. The upper auricle or Atrium and the lower larger ventricle. VALVES There are walls between left Atrium and left...

  The basic definitions and working of heart are covered in other page  BLOOD   CLOTTING When a tissue is wounded or a blood vessel is ruptured due to some injury the blood flows through it.  If not checked it may cause an excessive loss of blood. Sometimes this immense loss of blood even leads to death.  However the body has its own natural device of preventing the loss of blood by forming a blood clot which heals blood cell injury and stops flow of blood and also checks the entry of pathogenic microorganisms.  This complex process is initiated by PLATELETS which circulates within blood around the body.   Mechanism of blood clotting  In the region of injury, the platelets get ruptured and release a substance called thromboplastin .  It converts protein prothrombin into thrombin.   Vitamin K is essential for formation of thrombin in liver. THROMBIN then changes soluble fibrinogen protein into fibrin(insoluble). This latter goes Rap...
