TRUE or FALSE
The heart is the hardest working muscle in your body.
TRUE
TRUE or FALSE
Your heart pumps over 20,000 gallons of blood throughout your body each day.
FALSE
Truth: Your heart pumps over 2,000 gallons of blood throughout your body each day.
TRUE or FALSE
If you were to stretch out your blood vessel system, It would extend over 6,000 miles

TRUE or FALSE
A woman’s heart beats slightly faster than a man’s.
TRUE
TRUE or FALSE

FALSE
Truth: Laughing is good for your heart. It reduces stress and gives a boost to your immune system.
What does the Circulatory or Cardiovascular System do?
- Transports materials throughout the entire body
- Transports nutrients, water, and oxygen to the billions of body cells
- Heals and fights infections and removes wastes
- Intricate highway that travels throughout the entire body
It keeps the body working by delivering oxygen to body cells and removing waste (Co2) from the cells
Circulatory System
It pumps the blood throughout the body
Heart
Blood Vessels
Carries the blood throughout the body
It carries the materials throughout the body.
Blood
What is divided into four chambers?
The Heart
What are the 2 types of Arteries?
Aorta and Pulmonary Artery
It is the largest blood vessel in the heart
Aorta
It carries blood containing Carbon Dioxide from your heart to your lungs
Pulmonary Artery
What are the 3 types of Veins?
Inferior Vena Cava
Superior Vena Cava
Pulmonary Vein
What is the Inferior Vena Cava?
Where the blood enters the heart from the body
It is where the blood enters the heart from the body
Superior Vena Cava
What is the Pulmonary Vein?
Carries blood-containing oxygen from your lungs to your heart
What are the four valves of the heart?
Tricuspid Valve
Bicuspid Valve
Right Semi Lunar Valve
Left Semi Lunar Valve
Lets the blood fill in the right atrium before it enters the right ventricle.
Tricuspid Valve
What is the Bicuspid Valve?
Lets the blood fill in the left atrium before it enters the left ventricle
Lets the right ventricle fill before releasing the blood into the pulmonary artery
Right Semi Lunar Valve
What is the Left Semi Lunar Valve?
Lets the blood fill in the left ventricle before sending it to the aorta
What is Septum?
Divides the heart in half
What are the 3 kinds of Blood Vessels?
Arteries
Veins
Capillaries
it carries blood away from the heart.
Arteries
What are Veins?
It carries blood back to the heart
It delivers low-oxygen blood to veins (Smallest)
Capillaries
What’s in the blood?
- Digested food
- White blood cells
- Waste (Urea)
- Platelets
- Hormones
- Plasma
- Carbon Dioxide
- Oxygen
- Red Blood Cells
It carries oxygen and contains Hemoglobin (Protein)
Red Blood Cells (Erthrocytes)
It is larger than red blood cells and less numerous than red blood cells. It also fights infections/Immunity.
White Blood Cells (Leukocytes)
These are cell fragments and they repair damaged blood vessels. They are also responsible for Blood Clotting.
Platelets
It is the liquid portion of blood. A mixture of water with dissolved substances, and it carries many things(Hormones, Amino Acids, Lipids, Glucose, Vitamins & Minerals, Carbon Dioxide)
Plasma
What are the four types of blood?
Type A
Type B
Type AB
Type O
RH Factor
It is the + and - of the blood.
It is 42% and accepts A and O
Type A
It is 10% and Accepts B and O
Type B
It is 3% and accepts AB and O
Type AB
It is 45% and is a Universal Donor
Type O
What are the four filters of the blood?
Liver
Kidneys
Lymph Nodes
Spleek
It is located in the neck and filters the blood.
Lymph Nodes
It is the cemetery for the red blood cells.
Spleen
It is the inability of kidneys to function, resulting in accumulation of fluid and waste products in the body
Kidney Failure
Blood does not clot properly
Hemphilia
What is the treatment for Hemophilia
Transfusions of blood clotting factors
Prevention of Diseases and disorders of the circulatory system
Don’t smoke
Drink in moderation
Get Cholesterol checked
Exercise 30 minutes daily
Consume a low fat diet
Treatment of Diseases and disorders of the circulatory system
Medication
Rehabilitation
It happens when a cluster of blood cells blocks blood vessels in the brain.
Stroke
It has abnormal white blood cells
Leukemia
A viral infection; with symptoms of sore throat, swollen glands and fatigue
Mononucleosis
Your blood is unable to circulate properly.
Sickle Cell Anemia
Lack of red blood cells or cells that do not carry enough oxygen
Anemia
Stoppage in the flow of blood to the heart.
Heart Attack
Arteriosclerosis
Artery walls harden; caused by a diet high in fat and cholesterol.
Used to measure blood pressure
Sphygmomanometer
An instrument used to listen to the sounds of the heart or listen to the flow of blood.
Stethoscope
Continuous elevation of blood pressure above the normal range
Ex: 140/90
High Blood pressure
A measure of the lowest pressure
Diastolic
A measure of the maximum force
Systolic
