Circulatory System Presentation Transcript

  • 1.  
  • 2.
    • To identify and describe the organs of the circulatory system
  • 3.
    • Responsible for transporting materials throughout the entire body, these materials include:
    • Blood
    • Oxygen
    • Carbon dioxide
    • Nutrients
    • Water
  • 4.
    • It is a hallow muscular organ, somewhat conical in shaped wherein the base is located superiorly and the apex is pointing inferiorly
    • It is about the same size of closed fist.
    • It is made-up of cardiac muscle which is involuntary type and striated
    • The weight in male varies from 280-340 gm and in female it is from 230-280 gm
  • 5.
    • It is located at middle mediastinum between the 2 nd rib and the 5 th intercostal space.
    • It is just beneath the body of the sternum and the joining parts of the rib cartilages
  • 6.
    • 1. Each contraction result to transport of oxygen into the system and pouring the lungs with blood containing carbon dioxide.
  • 7.
    • 2 atria and 2 ventricles, The smallest atria is the left atrium and the largest ventricle is the left ventricle.
  • 8.
    • The 1 st heart chamber
    • It is obliquely formed quadrangular in shape;
    • It receives blood coming from the superior and inferior vena cava and the coronary sinus
    • It houses the pacemaker of the heart or the SA node as well as the AV node
    • It pumps the blood into the right ventricle via tricuspid valve
  • 9.
    • The 2 nd heart chamber
    • Triangular in shaped that extends form the right atria to the apex
    • The undersurface is flattened, rests upon the diaphragm
  • 10.
    • The 3 rd chamber and the smallest chamber in the heart.
    • It communicates with pulmunary veins and left ventricle via bicuspid valve
  • 11.
    • The 4 th chamber and the biggest of the 4 chambers of the heart
    • It has a thick myocardium and it communicate with aorta by means of its valve
  • 12. Viceral Pericardium Myocardium Endocardium
  • 13.
    • Is a fibroserous sac that encloses the heart and the roots of the great vessels.
    • Its function is to restrict excessive movements of the heart as a whole and to serve as a lubricated container in which the different parts of the heart can contract
  • 14. Pulmonary valve Tricuspid valve
  • 15. Mitral Valve
  • 16.
    • Sinuatrial node
    • AKA- Pacemaker
    • It initiates the heart beat and it is located at the walls of the right atrium in the upper part of sulcus terminalis close to SVC
    • Atrioventricular node
    • It is located on the lower part of the atrial septum just above the attachment of the sepyal cusp of tricuspid valve
  • 17.
    • Atrioventricular bundles – R and L side
    • Is a continuous with the AV node above and purkinje fibers below
    • It descends behind the septal cusp of the tricuspid valve on the membranous part of ventricular septum
    • Purkinje fibers
    • A specialized cardiac muscle fibers that form the conducting system of the heart
    • It is the terminal/ end of the system
  • 18. There are 3 types Of Circulations in body pulmonary coronary systemic
  • 19.
    • Pulmonary circulation is the movement of blood from the heart, to the lungs, and back to the heart.
  • 20.
    • Low O2 blood enters the right atrium via Vena cava.
    • To the right ventricle (via a one way valve)
    • Right ventricle contracts and sends the low O2 blood to lungs through the Pulmonary artery.
  • 21.
    • In the lungs capillaries, blood exchanges CO2 with O2
    • O2 rich blood enters into the left atrium via the pulmonary vein
    • Follows by entry to the left ventricle( via a one way valve)
  • 22.
    • Left ventricle contraction forces the blood in to the Aorta
    • From this point blood begins its journey throughout the body
  • 23.
    • While the circulatory system is busy providing oxygen and nourishment to every cell of the body, let's not forget that the heart, which needs nourishment as well as other parts of the body. Coronary circulation refers to the movement of blood through the tissues of the heart.
    • The heart tissue receives nourishment through the capillaries located in the heart.
  • 24.
    • Systemic circulation supplies nourishment to all of the tissue located throughout your body, with the exception of the heart and lungs.
    • In this circulation, the oxygen-rich blood enters the capillaries where the oxygen and nutrients are released. The waste products are collected and the waste-rich blood flows into the veins in order to circulate back to the heart.
  • 25.  
  • 26.  
  • 27. Systemic circulation has two smaller sub circulation within it Renal circulation Portal circulation
  • 28.
    • During systemic circulation, blood passes through the kidneys. This phase of systemic circulation is known as renal circulation. During this phase, the kidneys filter much of the waste from the blood.
    • Blood also passes through the small intestine during systemic circulation. This phase is known as portal circulation. During this phase, the blood from the small intestine collects in the portal vein which passes through the liver. The liver filters sugars from the blood, storing them for later.
