CARDIOVASCULARSYSTEM

KEY TERMS

Cardiovascular System Key Terms

FRONT

• Cardio/Cardiac

BACK

• Having to do with the Heart

Cardiovascular System Key Terms

FRONT

•HEART

BACK

• Muscular organ responsible for pumping blood throughout the body• Size of your fist

Cardiovascular System Key Terms

FRONT

•ATRIUM

BACK

• Upper chambers of the heart (2)

Cardiovascular System Key Terms

FRONT

•VENTRICLES

BACK

• Lower chambers of the heart (2)

Cardiovascular System Key Terms

FRONT

•VALVES

BACK

• Flap-like structures found between the atrium and the ventricle

• They are responsible for the “Lub-dub” sound of your heartbeat when they close

Cardiovascular System Key Terms

FRONT

• SEPTUM• (See yellow part of your

model)

BACK

• Tissue separating the chambers of the heart

• (also between your nostrils)

Cardiovascular System Key Terms

FRONT

•ARTERIES

BACK

• Carry blood AWAY from the heart• In the BODY, they

carry oxygen –RICH blood

Cardiovascular System Key Terms

FRONT

•VEINS

BACK

• Carry blood TOWARD the heart

• In the BODY, they carry oxygen –POOR blood, carbon dioxide, and waste products.

Cardiovascular System Key Terms

FRONT

•CAPILLARIES

BACK

• Tiny blood vessels that allow the exchange of gases and waste products between the blood and the body cells

• Connect the arteries and the veins

• A C V C A

Cardiovascular System Key Terms

FRONT

•RED BLOOD CELLS

BACK

• Responsible for transporting oxygen, carbon dioxide, and other waste products

Cardiovascular System Key Terms

FRONT

•WHITE BLOOD CELLS

BACK

• Responsible for fighting disease

Cardiovascular System Key Terms

FRONT

•PLATELETS

BACK

• Clot together to stop bleeding• (scabs)

Cardiovascular System Key Terms

FRONT

•PLASMA

BACK

• Liquid portion of the blood, in which the RBC, WBC, and platelets are suspended

• Like the liquid in a snowglobe

Cardiovascular System Key Terms

FRONT

•VASCULAR

BACK

• The system of specialized tubes that transport material (blood) from one part of the body to another

• Veins, arteries, & capillaries

Cardiovascular System Key Terms

FRONT

• LUNGS(pulmonary)

BACK• Organs where

oxygen (O2) is inhaled and carbon dioxide (CO2) is exhaled in/out of the body

Cardiovascular System Key Terms

FRONT

• RESPIRATION

BACK• Does not occur in the

lungs!!!• Occurs at the cell level• Capillaries exchange

oxygen and carbon dioxide with individual cells in the body.

Cardiovascular System Key Terms

FRONT

• OXYGEN

BACK• The main source of

energy for cells

• The necessary product for respiration

• Inhale Lungs Blood Cell

Cardiovascular System Key Terms

FRONT

• CARBON DIOXIDE

BACK• The main WASTE product of

respiration

• Cell Blood HeartLungs Exhaled

Cardiovascular System Key Terms

FRONT

• PULMONARY ARTERY

BACK• Left/Right Lung Artery

• Brings Oxygen-POOR blood AWAY from the Heart TO the Lungs

Cardiovascular System Key Terms

FRONT

• PULMONARY VEIN

BACK• Right/Left Lung Vein

• Brings Oxygen-RICH blood TOWARDS the Heart from the Lungs

Cardiovascular System Key Terms

FRONT

• AORTA

BACK• The LARGEST artery

• Transports Oxygen-RICH blood from the lungs heart out to the body

Cardiovascular System Key Terms

FRONT

• VENA CAVA

BACK• Transports Oxygen-POOR

blood from the body back to the heart

• Superior/Upper Vena Cava – transports blood from the upper body

• Inferior/Lower Vena Cava – transports blood from the lower body

Cardiovascular System Key Terms

FRONT

• PULMONARY CIRCULATION

BACK• The circulation of

blood between your heart and your lungs

• O2 POOR blood goes from the heart to the lungs Drops off CO2 and waste products/Picks up O2 goes back to the Heart

Cardiovascular System Key Terms

FRONT

• SYSTEMIC CIRCULATION

BACK• The circulation of

blood between your heart and your BODY

• O2 RICH blood goes from the heart out to the BODY Drops off O2 and Picks up CO2 and waste products goes back to the Heart
