Anatomical orientation
  • Anatomical Planes
  • frontal (coronal), sagital, transverse
  • Proximal vs distal
  • Anterior vs posterior
  • Superior vs inferior

The cardiovascular system
  • Heart
  • Blood vessels
  • arteries
  • veins
  • capillaries
  • Blood

10
Anatomical Position of the Heart
  • What organs or tissues are around the heart?
  • Anterior?
  • Posterior?
  • Left?
  • Right?
  • Superior?
  • Inferior?

11
Anatomical Position of the Heart
12
Layers of the Heart
Superficial
Deep
13
Layers of the Heart
  • Endocardium
  • deepest layer of the heart
  • smooth lining to reduce friction of bloodflow
  • Myocardium
  • middle layer of the heart
  • location of muscle fibers responsible for pumping
  • Pericardium
  • outer protective layer
  • composed of
  • visceral pericardium
  • paricardial cavity
  • parietal pericardium

14
Cardiac Chambers
Right Atrium
Left Atrium
Left Ventricle
Right Ventricle
15
Heart Chambers
  • Atriums
  • Receives blood from veins
  • Empties blood into ventricles through the AV
    valves.
  • Smaller, sac-like chambers of the heart
  • Ventricles
  • Receives blood from atriums through AV valves
  • Pumps blood away from heart through the semilunar
    valves.
  • Large, muscular chambers of the heart.

16
Blood Vessels Connected to the Heart
Aorta
Superior Vena Cava
Pulmonary arteries
Pulmonary viens
Inferior Vena Cava
17
Blood Vessels Connected to the Heart
Systematic circuit
  • Superior Vena Cava
  • collects deoxygenated blood from upper body and
    delivers it to right atrium
  • Inferior Vena Cava
  • collects deoxygenated blood from lower body and
    delivers it to right atrium
  • Aorta
  • carries oxygenated blood from the left ventricle
    to the rest of the body

18
Blood Vessels Connected to the Heart
Pulmonary circuit
  • Pulmonary arteries
  • carries deoxygenated blood to the lungs from the
    right ventricle
  • Pulmonary veins
  • carries oxygenated blood from the lungs to the
    left atrium

19
Valves
Pulmonary semilunar valve
Right AV (tricuspid) valve
Aortic semilunar valve
Chordai tendineae Papillary muscle
Left AV (bicuspid) valve
20
Valves of the Heart
Atrioventricular valves Semilunar valves
  • Right AV (Tricuspid)
  • separates the right atrium from the right
    ventricle. Prevents backflow into atrium.
  • Left AV (Bicuspid)
  • separates the left atrium from the left
    ventricle. Prevents backflow into atrium.
  • Pulmonary valve
  • separates the right ventricle from the pulmonary
    arteries. Prevents backflow after ventricular
    contraction.
  • Aortic valve
  • separates the left ventricle from the aorta.
    Prevents backflow after ventricular contraction .
