1. Circulatory System in Human
By:-
Prof. Umesh Khaire

2. •HUMAN CIRCULATORY SYSTEM CONSIST OF
HEART (PUMPING ORGAN)
BLOOD VESSELS(ARTERIES AND VEINS)
BLOOD(CIRCULATORY MEDIUM )

3. BLOOD(CIRCULATORY MEDIUM )
• BLOOD IS FLUID CONNECTIVE TISSUE WHICH IS FLUID IN NATURE CONSIST OF
FOLLOWING COMPONENTS
I. PLASMA :-YELLOW COLORED FLUID PRESENT IN BLOOD WHICH TRANSPORT
FOOD AND NITROGENOUS WASTE
II. RED BLOOD CELL (RBC):-
• IT TRANSPORT GASSES FROM LUNG TO ALL PARTS OF HUMAN BODY
• DUE TO HEMOGLOBIN ITS COLOR IS RED
III. WHITE BLOOD CELL(WBC):-
• WBCs protect us by attacking to disease causing agent enter in the
body
IV. Platelets:- it helps to stop blooding after injury by clotting the blood

5. BLOOD VESSELS(ARTERIES AND VEINS)
• There are three types of blood vessels in human body as following
1. Arteries :-
• It have thick wall and narrow passage with no valves
• It carry blood away from heart to different part of body
• It carry oxygenated blood
(Expectational Pulmonary arteries that carry deoxygenated blood from heart to lung )
2. Veins :-
• It have thin wall with wide passage and valves
• It carries blood from different part of body towards heart
• It carries deoxygenated blood
(Expectational Pulmonary veins that carry oxygenated blood from lung to
heart )

6. 3. Capillaries :-
 It have very thin valves with no valves
 Capillary connect veins and arteries and help to exchange substance
between blood and cell

9. HEART (PUMPING ORGAN)
• The heart is a muscular organ that roughly the size of a fist and weight 350-350
gram
• It pumps the blood and maintain blood circulation in human body
• It divided into four chamber
I. Left atrium
II. Right atrium
III. Left vertical (pumping part)
IV. Right vertical(Pumping Part)
• This chamber are separated by partition called septum
• Valves ensure the blood in one direction

12. THE FLOW O BLOOD THROUGH HEART
• The pulmonary veins carry oxygenated blood from lungs to the left
atrium
• Left atrium relaxed and receive blood get contract and pumps blood in
to left ventricle
• Left ventricle relaxed receive blood and contract and pumps the blood
through aorta and arteries though out body
• The oxygenated blood enter in tissue and release oxygen and and gain
carbon di oxide

13. • These carbon di oxide reach blood is being carried by Vena cava
(Veins ) towards right atrium
• Right atrium receive the carbon di oxide reach blood from the body and
contract and pump it into right verticals contracted and pump carbon di
oxide rich blood in to pulmonary arteries
• pulmonary arteries carries carbon di oxide rich blood from right
verticals to the lungs
• This cycle is continue
• The oxygen rich blood flows from lungs to heart and heart pumps thses
blood to the other part of the body

14. • The oxygen rich blood flows from lungs to heart and heart pumps
theses blood to the other part of the body the carbon di oxide rich
blood flows from body to heart the heart pumps it back into the
lungs .this cycle in which blood passes twice through heart so is
called double circulation

19. BLOOD PRESSURE
• When blood is flow through blood vessels is exert pressure on walls
of vessels this is called blood pressure
• It is higher in arteries than veins therefore it is measured in arteries
• The device used to measure blood pressure is a sphygmomanometer

20. TYPES OF BLOOD PRESSURE
Systolic
•The pressure of blood in side
of arteries during the
ventricular contraction is
called Systolic blood pressure
Diastolic
•The pressure of blood in side
of arteries during the
ventricular relaxation is
called diastolic blood
pressure

22. •The normal range of blood pressure is
(Systolic ) 120/80 (Diastolic)

23. NUMBER OF CHAMBER IN HEART OF DIFFERENT ANIMALS
• TWO CHAMBERS: ONE ATRIUM AND ONE VENTRICLE (FISH)
• THREE CHAMBERS: TWO ATRIAAND ONE VENTRICLE
(AMPHIBIAN AND REPTILE)
• FOUR CHAMBERS: TWO ATRIAAND TWO VENTRICLES
(BIRD AND MAMMAL)

26. Lymphatic System

27. The lymphatic system is a network of lymph nodes connected by lymphatic
vessels.
This system transports lymph throughout the body.
