Title: CIRCULATORY SYSTEM A


1
CIRCULATORY SYSTEMAP 4
  • By Angie Lawson RN, BSN

2
HEARTS LAYERS COVERINGS
  • Endocardium- innermost layer
  • Myocardium middle layer, muscle tissue
  • Epicardium outermost layer, cont. with
    pericardium
  • Pericardium sac the heart lies in

3
HEARTS CHAMBERS
  • Right Atrium thin walled receives
    unoxygenated blood
  • Right Ventricle- sends unoxygenated
    blood to the lungs
  • Left Atrium- receives oxygenated blood from
    lungs
  • Left Ventricle- thickest chamber sends oxygenated
    blood to the body

4
HEART VALVES(Purpose Keep blood flowing forward)
  • Atrioventricular Valves between the atrium
    ventricles
  • Tricuspid valve right AV valve
  • Bicuspid valve mitral valve
  • Semilunar Valves between the ventricles and
    main arteries
  • Pulmonic valve (pulmonary)
  • Aortic valve

6
CORONARY BLOOD SUPPLY
  • Right Coronary Artery
  • Left Coronary Artery
  • Left Anterior
  • Descending
  • Circumflex Artery
  • Coronary Veins
  • Coronary Sinus

7
CARDIAC CONDUCTION
  • Sinoatrial Node (SA)
  • Atrial Conducting Fibers
  • Atrioventricular Node (AV)
  • His-Purkinje System

8
ELECTROCARDIOGRAM
  • P Wave
  • QRS Complex
  • T Wave
  • P-R Interval

9
CARDIAC CYCLE
  • Atrial Systole atrium contract
  • Ventricular Systole ventricles contact, atrium
    relax
  • Diastole both the ventricles and atrium relax

10
CARDIAC OUTPUTCO HR X SV
  • HR Heart Rate
  • SV Stroke Volume

11
TYPES OF CIRCULATION
  • Pulmonary
  • Systemic

12
BLOOD VESSELS
  • Arteries
  • Capillaries
  • Veins

13
BLOOD VESSEL WALLS
  • Tunica Intima
  • Tunica Media
  • Tunica
  • Adventitia

14
VESSELS IN ORDER
  • Arteries conductance vessels
  • Arterioles resistance vessels
  • Capillaries- exchange vessels
  • Venules- capacitance vessels
  • Veins larger venules

15
SYSTEMIC CIRCULATION ARTERIES
  • Aorta
  • Branches of the
  • Aorta
  • Ascending aorta
  • Aortic arch
  • Descending aorta
  • Thoracic aorta
  • Abdominal aorta

16
SYSTEMIC CIRCULATIONVEINS
  • Venae Cavae
  • Superior
  • Inferior

17
SUPERIOR VENAE CAVAE
  • Cephalic vein
  • Basilic vein
  • Median cubital vein
  • Subclavian vein
  • Internal juglar vein
  • Brachiocephalic vein
  • Azygos vein

18
INFERIOR VENAE CAVAE
  • Tibial vein
  • Peroneal vein
  • Posterior tibial vein
  • Femoral vein
  • External iliac vein
  • Common iliac vein
  • Great saphenous vein
  • Renal Hepatic vein

19
SPECIAL CIRCULATIONS
  • Head Neck
  • Head Brain
  • Liver Hepatic Portal
  • Fetal

20
HEAD NECK ARTERIES
  • Common carotid arteries
  • External carotid arteries
  • Internal carotid arteries
  • Vertebral arteries
  • Basilar artery
  • Circle of Willis

21
HEAD BRAIN VEINS
  • Internal jugular vein
  • External jugular vein

22
LIVER HEPATIC PORTAL CIRCULATION
  • Portal vein
  • Superior mesenteric vein
  • Splenic vein
  • Inferior mesenteric vein

23
FETAL CIRCULATION
  • Umbilical vein (1)
  • Umbilical arteries (2)
  • Placenta - serves as
  • the lungs

24
BLOOD PRESSURE
  • Systolic pressure
  • Diastolic pressure
  • Pulse pressure

25
DETERMINING B/PB/P CO X VR
  • CO Cardiac Output
  • VR Vascular Resistance

26
BARORECEPTOR REFLEX
  • Receptors
  • Sensory nerves
  • Medulla oblongata
  • Motor nerves

27
WHY CAPILLARIES WORK
  • Thin walls
  • Holes in walls
  • Slow flow
  • Diffusion
  • Filtration-osmosis
