Science

1. What keeps the blood moving!

2. 1. Identify parts of the circulatory system.
2. Describe the function of the parts of the
circulatory system.
3. Explain ways to take care of the
circulatory system.

3. Explain three ways how the
circulatory system is like an
transportation system. Trucks,
Buses, and cars!
This should be one paragraph!

4.  Cardiovascular system
 Pulmonary system
 Systemic system
 Arteries
 Veins
 Capillaries
 blood

5. Cardiovascular system – organs and
tissues that transport essential
materials to body cells
Pulmonary system – Flow of blood
from the heart to the lungs and back
to the heart.
Systemic system – Flow of blood to
the body tissues except the lungs.

6. Arteries – Vessels that carry blood
away from the heart to other parts
of the body.
Veins - Vessels that carry blood
from the body back to the heart.
Capillaries – Tiny tubes that carry
blood from the arteries to the cells,
and back to the veins.

8.  50% Water
 45% Red Blood cells
 4% Plasma with
Substances
 1% Leukocytes
(WBC) and Platelets

9.  Transporters of
 Oxygen
 Carbon Dioxide
 RBC
 Lack a nucleus
 Contain hemoglobin
 Disk-shaped
 RBC are produced in red bone
marrow of
 ribs,
 humerus,
 femur,
 sternum, and other long bones
 Lives for 120 days
 Old RBC are destroyed in liver
and spleen

10.  WBC fight infection
 Attack foreign substances
 Less abundant
 Large cells
 Some live for months
 Most just a few days
 Several types
 ALL contain nuclei

11. Break in Capillary
Wall
Blood vessels injured.
Clumping of Platelets
Platelets clump at the
site and release
thromboplastin.
Thromboplastin
converts prothrombin
into thrombin..
Clot Forms
Thrombin converts
fibrinogen into fibrin,
which causes a clot.
The clot prevents
further loss of blood..
 PLATELETS are for CLOTTING blood
 Cell fragments
 Produced in bone marrow
 Short life span (1 week)
 Fibrin (sticky network of protein fibers)
 Form a web trapping blood cells

12.  There are four blood
types. A, B , AB, and
O.
1. A+, A-
2. B+, B-
3. Ab+, Ab-
4. 0+, O-
~ All blood have Rh
~ The Rh determined the
blood type.

13. VEINS and ARTERIES

16.  STEP ONE

18. The cycle then repeats
itself.

19.  Hypertension –
High blood
pressure.
 Stroke – blood
clots that block a
vessel.
 Heart attack –
blockage of flow of
blood to the heart.
 Arteriosclerosis –
arteries harden,
reducing blood
flow.
 Anemia – Low
level of
hemoglobin
(protein that binds
to oxygen in RBC.)
 Leukemia disease
with extra WBC
are made.
 Hemophilia –
disease that does
not have blood
plasma substance
to help blood clot.

20.  Limit fat intake in
your foods –
Example:
McDonalds.
 Physical Activity – 30
minutes or more a
day keeping your
heart rate above 150
bpm
 Avoid tobacco
 Manage stress
