Instructions for Side by Side Printing
  1. Print the notecards
  2. Fold each page in half along the solid vertical line
  3. Cut out the notecards by cutting along each horizontal dotted line
  4. Optional: Glue, tape or staple the ends of each notecard together
  1. Verify Front of pages is selected for Viewing and print the front of the notecards
  2. Select Back of pages for Viewing and print the back of the notecards
    NOTE: Since the back of the pages are printed in reverse order (last page is printed first), keep the pages in the same order as they were after Step 1. Also, be sure to feed the pages in the same direction as you did in Step 1.
  3. Cut out the notecards by cutting along each horizontal and vertical dotted line
To print: Ctrl+PPrint as a list

31 notecards = 8 pages (4 cards per page)

The Cardiovascular System: The Heart

front 1

A transport system pump

back 1

Heart

front 2

Receives oxygen-poor blood from body tissues

back 2

Right side of the heart

front 3

The blood vessels that carry blood to and from the lungs

back 3

Pulmonary Circuit

front 4

Receives oxygenated blood

back 4

Left side of the heart

front 5

The blood vessels that carry blood to and from all body tissues

back 5

Systemic Circuit

front 6

Two receiving chambers of the heart

back 6

  • Right Atrium
  • Left Atrium

front 7

Two main pumping chambers of the heart

back 7

  • Right Ventricle
  • Left Ventricle

front 8

The medial cavity of the thorax that encloses the heart

back 8

Mediastinum

front 9

A double-walled sac that encloses the heart

back 9

Pericardium

front 10

  1. Protects the heart
  2. Anchors it to surrounding structures
  3. Prevents overfilling of the heart with blood

back 10

The fibrous pericardium

front 11

A thin, slippery, two-layer serous membrane that forms a closed sac around the heart

back 11

Serous Pericardium

front 12

The three layers of the heart wall

back 12

  • Epicardium
  • Myocardium
  • Endocardium

front 13

The superficial visceral layer of the serous pericardium

back 13

Epicardium

front 14

The middle layer that is composed mainly of cardiac muscle and forms the bulk of the heart

back 14

Myocardium

front 15

The third layer of the heart wall is a glistening white sheet of endothelium resting on a thin connective tissue layer

back 15

endocardium

front 16

The four chambers of the heart

back 16

  • two superior atria (Left and Right)
  • two inferior ventricles (Left and Right)

front 17

Separates the atria from left and right

back 17

The interatrial septum

front 18

Separates the ventricles from left and right

back 18

interventricular septum

front 19

Encircles the junction of the atria and ventricles

back 19

Coronary sulcus

front 20

The right atrium has two basic parts

back 20

  • A smoothed-walled posterior part
  • An anterior portion in which bundles of muscle tissue, called pectinate muscles, form ridges in the walls

front 21

The receiving chambers for blood returning to the heart from the circulation

back 21

Atria

front 22

Blood enter the right atrium via three veins

back 22

  • Superior vena cava
  • Inferior Vena Cava
  • Coronary Sinus

front 23

The discharging chambers, the actual pumps of the heart

back 23

Ventricles

front 24

Pumps blood into the pulmonary trunk which routes the blood to the lungs where gas exchange occurs

back 24

Right ventricle

front 25

Ejects blood into the aorta

back 25

Left ventricle

front 26

Irregular ridges of muscles that mark the internal walls of the ventricular chambers

back 26

trabeculae carneae

front 27

The two valves that prevent backflow into the atria when the ventricles contract

back 27

Atrioventricular (AV) valves

front 28

The right AV valve, which has three flexible cusps

back 28

Tricuspid valve

front 29

The left AV valve, which has two flexible cusps

back 29

Mitral Valve also known as bicuspid valve

front 30

Attached to each AV valve flap are tiny white collagen cords which anchor the cusps to the papillary muscles protruding from the ventricular walls

back 30

Chordae Tendineae

front 31

The two semilunar (SL) valves that guard the bases of the large arteries issuing from the ventricles and prevent backflow into the associated ventricles

back 31

  • Aortic Valve
  • Pulmonary Valve
