CIRCULATORY SYSTEM
WHAT IS CIRCULATORY SYSTEM ?
ALL THE PARTS OF THE BODY THAT HELP IN THE TRANSPORTATION OF VARIOUS BODY
MATERIALS BIN THE BODY CONSTITUTE THE CIRCULATORY SYSTEM.
1. THE FLUID TRANSPORT MEDIUM AKA BLOOD AND LYMPH
2. CONTROLLING CENTRE: HEART
3. PATH THROUGH WHICH BLOOD CIRCULATES: BLOOD AND LYMPH VESSELS
FLUIDS IN OUR BODY
40 LITRES OF FLUID IS PRESENT IN AN AVERAGE HUMAN BODY
25 LITRE CALLED INTRACELLULAR FLUID IS PRESENT IN THE CELLS
REMAINING 15 LITRE IS PRESENT BETWEEN WMPTY SPACES IN THE BODY
THE EXTRA CELLULAR FLUIDS ARE:
BLOOD: THE REMARKABLE RED COLOURED FLUID FLOWING THROUGH THE HEART AND BLOOD
VESSELS.
TISSUE FLUID: COLOURLESS FLUID OCCUPYING SPACES BETWEEN VARRIOUS SPACES IN CELLS
OF AN ORGAN. CELL ABSORB OXYGEN AND GIVE OUT CARBON DIOXIDE THROUGH THIS FLUID
LYMPH: IT IS A FAINT YELLOW COLOURED FLUID CONSIST OF LYMPH VESSELS AND LYMP
ORGANS. LYMPH VESELS ON THE WAY BEAR LYMPH NODES. IT CONSIST OF ONLY WBC.IT
SUPPLIES BLOOD AND OXYGEN TO THOSE PARTS WHERE BLOOD CAN NOT REACH.
LYMPHOCYTES AND MONOCYTES DEFEND OUR BODY BY REMOVING BACTERIA FROM TISSUES.
FATS FROM INTERSTINE ARE ABSORBED THOUGH LYMPHOCYTES
BLOOD
WHEN OXYGENATED BRIGHT RED WHEN DEOXYGENATED DARK RED IN COLOUR.
IT FORMS ABOUT 8-10% OF OUR BODY WEIGHT
IT IS SALTISH IN TASTE, SLIGHTLY ALKALINE
ALWAYS KEEP CIRCULATING IN THE BODY THROUGH BLOOD VESSELS
ARTETIES: AWAY FROM HEART (EXCEPT PULMONARY)
VEINS: TOWARDS THE HEART (EXCEPT PULMONARY)
COMPOSITION OF BLOOD
1. PLASMA
IT IS THE LIQUID PORTION OF THE BLOOD
SLIGHTLY YELLOW IN COLOUR
50%-60% OF BLOOD
90%-92% IS MADE UP OF WATER
7%-8% OF PROTIENS
1% INORGANIC SALTS OF SODIUM BICARBONATE AND SODIUM CHLORIDE
ALUBIMNS GLOBULINS FIIBRINOGEN AND PROTHROMBIN ARE THE PROTIENS
GLUCOSE, AMINO ACIDS, FATTY ACID, UREA, URIC ACID, AMMONIUM SALTS AND ACIDS
