Cardiovascular
& Circulatory
Systems
Cardiovascular &
Circulatory
System
Function:
The Body’s Transport System
1. Heart
2. Blood Vessels
3. Blood
Structures - Heart
1. Shape - Strawberry
2. Size - Fist
3.
Weight - 1 pound
4. Location –
Center of chest
THE HEART
Heart - Structures
1. Septum – Divides the
Heart into Right and Left
2. Chambers -
Note:
It Is A Hollow Organ
Atrium – Top (smaller)
Ventricle – Bottom (bigger)
3. Valves – Keep blood
flowing in one direction

Blood Vessels
1. Arteries – (RED) Carries
Blood Away from the Heart
2. Veins – (BLUE) Carry
Blood Back to the Heart
3. Capillaries –
Where
exchange of nutrients takes
place (O2, Waste, Etc…)

Blood Pressure
Definition: The Force of the
Blood against the Walls of
the Arteries
Systole: Top Number of Blood
Pressure (ventricles
contracting)
Diastole: Bottom Number
of Blood Pressure (ventricles
filled w/ blood)
Blood - Function
1. Carries food and
oxygen to all cells
2. Rids the body of
Waste
Blood -
Components
1. Red Blood Cells
- Erythrocytes
2. White Blood Cells
- Leukocytes
3. Platelets
- Thrombocytes
4. Plasma
Red Blood Cells
1. Made in the Marrow of
Bones
2. Carry Oxygen
3. Hemoglobin
- The Protein that
attracts O2 to the RBC
- Prone to Defect/illnesses

White Blood Cells
1. Made in the Marrow of
Bones
2. Defend the Body
against Disease
Plasma
1. The Liquid part
of Blood (55%
of blood)
2. Mostly
Water
Blood Components
Platelets
1. Aid in Blood Clotting
2. How Does Blood Clot?
-
Cut occurs. Platelets Activated.
Platelets RUSH to the wound
Fibrin is released (Spider Web)
Web is formed over Wound
Trapped Cells Harden and
form a Scab
PLATELETS = SPIDERMAN
PLATELETS- STEP 1
 Cut occurs…. Platelets Actived!
PLATELETS – STEP 2
 Platelets RUSH to the wound!
PLATELETS- STEP 3
 Fibrin is released (Spidey Web)
PLATELETS – STEP 4
 Web is formed over Wound.
PLATELETS – STEP 5
-Trapped Cells Harden and form a Scab
SPIDEY SAVES THE DAY 

Really hard Logic/Blood Type Puzzle?
Use the following information to predict each person's blood type.
Bill can give blood to joe mike and sue
Don can give blood to bob but not bill
Bob can give blood to Mike but not Joe
Tom can give blood to kelly, Sue, Don, and mike
Kelly can give blood to sue and bob but not to tom
sue cannot give blood to kelly
joe can give blood to mike but not bob or sue
mike can GET blood from sue and bill
Joe does not have an A antigen
Bill________
Bob_______
Don_______
Joe_______
Kelly______
Mike_______
Sue_______
Tom_______
Answer in terms of blood type (A, B, AB, or O)
By the way, this may help:
a can be given to a or ab
b can be given to b or ab
ab can be given to ab
o can be given to anyone
