Human Anatomy & Physiology

Cardiovascular System

Lymphatic System

Respiratory System

Digestive System

cardiovascular system
Cardiovascular System
  • Layers of heart wall
    • Pericardium
      • Parietal
      • Visceral
        • Epicardium
    • Myocardium
    • Endocardium
      • Heart valves
slide3
Basically 2 pumps
    • Right
      • Pulmonary circulation
    • Left
      • Systemic circulation
slide4
Heart Chambers & vessels
    • Right atrium
      • Superior vena cava
      • Inferior vena cava
    • Right Ventricle
      • Pulmonary artery
    • Left atrium
      • Pulmonary veins (2)
    • Left Ventricle
      • Aorta
slide5
Heart Valves

Semilunar

Outflow valves

Pulmonary

Aortic

Atrioventricular

Strong

Tricuspid

Bicuspid

Mitral

slide6
Coronary circulation
    • First branch off aorta
    • Left
      • Anterior descending
      • Circumflex
    • Right
slide7
Conduction pathway
    • SA node
      • Pacemaker
    • AV node
    • Bundle of His
    • Left & Right bundle branches
    • Purkinje fibers
slide10
Blood Vessels
      • Arteries
        • distribution of nutrients
        • maintenance of blood pressure
      • Veins
        • takes waste products back to heart for circulation & disposal
        • valves keep flow going in one direction
      • Capillaries
        • where internal respiration occurs
          • i.e. the exchange of O2 & CO2 between vessel & cell
        • where exchanges occur for nutrients, wastes, and fluids
blood composition
Blood Composition
  • Blood = Plasma (55%) + Formed Elements (45%)
    • Plasma = the liquid faction of blood; blood minus its formed element
        • Serum = plasma minus clotting factors
pathology diseases
Anemia

Hemophilia

Leukemia

Phlebitis

Varicose veins

Aneurysm

Arteriosclerosis

Atherosclerosis

Thrombus & embolus

Hypertension

Congestive heart failure

Coronary artery disease

Angina

Myocardial infarction

Pathology(diseases)
lymphatic system
Structures

Lymph

Lymphatic vessels

Lacteals

Lymph nodes

Tonsils

Peyer’s patches

Thymus

Spleen

Thoracic duct

Lymphocytes

B lymphocytes

T lymphocytes

Functions

Immunity (defense)

Remove excess fluids

Lymphatic System
respiratory system
Respiratory System
