Presentation Transcript


Human anatomy physiology

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


Human anatomy physiology

  • Basically 2 pumps

    • Right

      • Pulmonary circulation

    • Left

      • Systemic circulation


Human anatomy physiology

  • Heart Chambers & vessels

    • Right atrium

      • Superior vena cava

      • Inferior vena cava

    • Right Ventricle

      • Pulmonary artery

    • Left atrium

      • Pulmonary veins (2)

    • Left Ventricle

      • Aorta


Human anatomy physiology

Heart Valves

Semilunar

Outflow valves

Pulmonary

Aortic

Atrioventricular

Strong

Tricuspid

Bicuspid

Mitral


Human anatomy physiology

  • Coronary circulation

    • First branch off aorta

    • Left

      • Anterior descending

      • Circumflex

    • Right


Human anatomy physiology

  • Conduction pathway

    • SA node

      • Pacemaker

    • AV node

    • Bundle of His

    • Left & Right bundle branches

    • Purkinje fibers


Human anatomy physiology

Cardiaccycle


Human anatomy physiology

  • Electrocardiogram (ECG)


Human anatomy physiology

  • 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


Capillary exchange filtration and osmosis

Capillary exchange: Filtration and osmosis


Respiratory system

Respiratory System

  • Structures

      • Bronchi

      • Bronchioles

      • Alveoli

      • Lungs

        • Left = 2lobes

        • Right = 3 lobes
