Bio4-Circulatory System

Front 1

Type of circulatory system in which blood flows out through vessels and sinuses.

Back 1

Open Circulatory System

Front 2

Type of circulatory system in which blood confined within connected walls of heart and blood vessels. General Characteristics: heart pumps blood, blood flows slowest in capillaries.

Back 2

Closed Circulatory System

Front 3

Type of Blood Vessel that is small and branch into capillaries. They usually carry oxygen rich blood.

Back 3

Arterioles/ Arteries are larger.

Front 4

These Blood Vessels carry blood back to the heart. They are smaller in diameter than arteries, usually carry oxygen-poor blood.

Back 4

Veins

Front 5

These are small veins.

Back 5

Venuoles

Front 6

These blood vessels are smallest in diameter, connect veinuous and arterial systems in capillary bed.

Back 6

Capillaries

Front 7

Type of blood circuit that functions to oxygenate the blood. Starts from the heart's right half to capillary beds located in lungs. The circuit then returns to the left half of blood.

Back 7

Pulmonary Circuit

Front 8

Type of blood circuit that functions to distribute oxygen rich blood and nutrients to body. Starts in the Left and Returns on the Right.

Back 8

Systemic Circuit

Front 9

Part of the heart that consists of the two upper chambers.

Back 9

Atrium (Plural Atria)

Front 10

The atrium that receives oxygen-poor blood from superior and inferior vena cava.

Back 10

Right Atrium

Front 11

The atrium that relieves oxygen-rich blood from the lungs, via the pulmonary veins.

Back 11

Left Atrium

Front 12

Parts of the heart that consists of the two lower chambers.

Back 12

Ventricles

Front 13

This ventricle pumps oxygen-poor blood from pulmonary arteries.

Back 13

Right Ventricles

Front 14

This ventricle pumps oxygen-rich blood to aorta.

Back 14

Left Ventricle

Front 15

These parts of the heart are located between the atrium and ventricles, they prevent blood back flow.

Back 15

Valves.

Front 16

This valve, is located between right atrium and right ventricle.

Back 16

Right AV (AKA Tricuspid Valves)

Front 17

These valves are located between the left atrium and left ventricle.

Back 17

Left AV (AKA Mitral Valve)

Front 18

This valve is located between right ventricle and pulmonary trunk.

Back 18

Pulmonary semi lunar valve.

Front 19

This valve is located between the left atrium and the left ventricle.

Back 19

Aortic semi lunar valve.

Front 20

This structure in the heart is a tendon-like tissue attached to valves (white and webby). They open and close valves by papillary muscles.

Back 20

Chordae Tendinae

Front 21

This is another name for the entire heart.

Back 21

Myocardium

Front 22

This blood vessel receives oxygen-poor blood from ABOVE the shoulder.

Back 22

Superior Vena Cava

Front 23

This blood vessel recieves oxygen-poor blood from below the shoulder.

Back 23

Inferior Vena Cava

Front 24

This vessel is large and leaves the right ventricle.

Back 24

Pulmonary Trunk

Front 25

These vessels carry oxygen-poor blood to the lungs

Back 25

Pulmonary Arteries

Front 26

These vessels carry oxygen-rich blood from lungs to the heart.

Back 26

Pulmonary Veins

Front 27

This large vessel carries oxygen-rich blood from left ventricle to the rest of the body. 1" in diameter.

Back 27

Aorta

Front 28

Carry rich blood to heart muscle

Back 28

Coronary Arteries (red)

Front 29

Carry oxygen-poor blood away from heart muscle

Back 29

Coronary Veins (blue)

Front 30

This is located in the upper wall of the right atrium.

Back 30

Sinotrial Node (Pacemaker)

Front 31

These are located in the wall between the right atrium and right ventricle. They make sure that the atria are empty before the ventricles contract.

Back 31

Atrio ventricular node

Front 32

When the heart passively fills with returning blood and then actively contracts pumping out blood.

Back 32

Cardiac Cycle

Front 33

Cycle in which heart relaxes and blood flows in

Back 33

Diastole

Front 34

brief contraction of the atria to completely fill ventricle

Back 34

Systole

Front 35

Volume of blood that the ventricle pumps into the systemic system.

Back 35

Cardiac Output

Front 36

A drop of blood begins at one of these two places to begin the circulatory system.

Back 36

Superior /Inferior Vena Cava

Front 37

Heart sound that indicates closing of AV Valves

Back 37

Lub

Front 38

Heart sound that indicates closing of semi-lunar valve.

Back 38

Dub

Front 39

This results from improper closing of heart valves. Valves can be leaky and may hiss.

Back 39

Heart murmur.

Front 40

This disorder is caused by patchy deposits of fatty material on walls of arteries.

Back 40

Atherosclerosis

Front 41

High Cholesterol is also called this

Back 41

Hypolipodemia

Front 42

Your total cholesterol should be LESS THAN

Back 42

200 mg/dL

Front 43

Your total LDL (low density lipo protein) should be LESS THAN

Back 43

100 mg/dL

Front 44

Your Triglycerides should be LESS THAN

Back 44
