Cardiovascular System
1. The c__________________ system includes the heart, blood vessels
(arteries, capillaries and veins), and blood. It delivers materials
(oxygen, white blood cells, glucose) to the body and carries waste
products (carbon dioxide, lymph) away. It also helps the immune
system.
Pathways of the Heart
1. Label the structures of the heart: Right Atrium, Left Atrium, Right
Ventricle, Left Ventricle, Aorta, Inferior vena cava, superior vena
cava, right pulmonary veins, left pulmonary veins, Left pulmonary
artery, right pulmonary artery
2. Use arrows to show the pathway of blood through the heart. Use
red for oxygen rich blood and blue for oxygen poor blood.
2. The Heart and its Pathways
H_______
a four chambered hollow, muscular organ that pumps
blood throughout the body each time it beats. The two
upper chambers are the a_______ and the pacemaker is
located there. The lower chambers are the
v___________.
Right
A______
receives oxygen p____ blood from the veins in the body
and pumps it to the right ventricle.
Right
V_______
pumps oxygen poor blood to the lungs. Though the
pulmonary arteries.
Left
A_______
receives oxygen r_____ blood from the lungs and sends it
to the left ventricle.
Left
V_______
pumps oxygen _____ blood through the aortic artery and
to the rest of the body.
V_______
(flaps of tissue) between the heart chambers that close
after blood passes through to prevent backflow. Also
found in veins.
3. Describe the flow of blood starting with the right atrium. Fill in
the blanks:
Right Atrium>>>>_____ ________>>>> Pulmonary _______>>>> Lungs
3. Blood Pressure
Systolic (_________ pressure)
Heart ___________ forcing
blood into the arteries and
blood vessels.
Diastolic (_________ pressure)
Heart ___________ and fills with
blood so there is less blood in
blood vessels.
>>>>> _________ veins>>>> _______ _______>>>> Left Ventricle>>>
>> _________ >>>> Smaller Arteries>>>> Capillaries >>>>> Smaller Veins
>>>> Inferior and superior _______ ________ >>>>>> Right Atrium.
