The circulatory systemis the body system thattransports Nutrients,OXYGEN & CELLULAR WASTE throughout the body.

•Plasma
•Blood cells
•Platelets

The 2 types of blood cells are:

Platelets help your blood clot

The function of White Blood Cells:
To attack, surround and destroy pathogens that enter the body and prevent them from causing infection.
When you have an infection, the number of white blood cells increases.

The function of Red blood cells:
To carry oxygen They are the most numerous
type of blood cells.They live about 100 days

3 Major types of Blood Vessels
are:1.Arteries2.Veins3.Capillaries
![Page 11: The circulatory system is the body system that transports Nutrients, OXYGEN & CELLULAR WASTE throughout the body.](https://reader036.fdocuments.net/reader036/viewer/2022062309/56649ea95503460f94badca9/html5/thumbnails/11.jpg)
Arteries These are the blood vessels that carry blood
AWAY from your heart.
![Page 12: The circulatory system is the body system that transports Nutrients, OXYGEN & CELLULAR WASTE throughout the body.](https://reader036.fdocuments.net/reader036/viewer/2022062309/56649ea95503460f94badca9/html5/thumbnails/12.jpg)
VeinsAre blood vessels
that carry blood
TO
the heart
![Page 13: The circulatory system is the body system that transports Nutrients, OXYGEN & CELLULAR WASTE throughout the body.](https://reader036.fdocuments.net/reader036/viewer/2022062309/56649ea95503460f94badca9/html5/thumbnails/13.jpg)
Cappillaries
Are tiny blood vessels that connect arteries and veins.
![Page 14: The circulatory system is the body system that transports Nutrients, OXYGEN & CELLULAR WASTE throughout the body.](https://reader036.fdocuments.net/reader036/viewer/2022062309/56649ea95503460f94badca9/html5/thumbnails/14.jpg)
The Heart is a
Muscle with 4 Chambers that
pump blood throughout the body.
![Page 15: The circulatory system is the body system that transports Nutrients, OXYGEN & CELLULAR WASTE throughout the body.](https://reader036.fdocuments.net/reader036/viewer/2022062309/56649ea95503460f94badca9/html5/thumbnails/15.jpg)
AtriumIs the
Upper Chamber of the Heart
![Page 16: The circulatory system is the body system that transports Nutrients, OXYGEN & CELLULAR WASTE throughout the body.](https://reader036.fdocuments.net/reader036/viewer/2022062309/56649ea95503460f94badca9/html5/thumbnails/16.jpg)
VentricleIs the
lower chamber
of the heart
![Page 17: The circulatory system is the body system that transports Nutrients, OXYGEN & CELLULAR WASTE throughout the body.](https://reader036.fdocuments.net/reader036/viewer/2022062309/56649ea95503460f94badca9/html5/thumbnails/17.jpg)
AortaIs the main artery in the body.
The aorta branches into smaller arteries and blood flows through to all parts of the body.

Blood Pressure
Is the force of blood against the artery
wall.
![Page 19: The circulatory system is the body system that transports Nutrients, OXYGEN & CELLULAR WASTE throughout the body.](https://reader036.fdocuments.net/reader036/viewer/2022062309/56649ea95503460f94badca9/html5/thumbnails/19.jpg)
Systolic Blood Pressure
Is the force of blood against the artery walls
when the heart is beating.
![Page 20: The circulatory system is the body system that transports Nutrients, OXYGEN & CELLULAR WASTE throughout the body.](https://reader036.fdocuments.net/reader036/viewer/2022062309/56649ea95503460f94badca9/html5/thumbnails/20.jpg)
Diastolic Blood Pressure
Is the force of blood against the artery
walls BETWEEN Heart beats.

TransfusionTransfusion
Is the transfer of blood between people.

Blood TypeBlood TypeIs the type of red
blood cells a person has.
Blood types: A , B , AB ,or O

1 - Oxygen-poor blood (shown in blue) flows from the body into the right atrium.
2 - Blood flows through the right atrium into the right ventricle.
3 - The right ventricle pumps the blood to the lungs, where the blood releases waste gases and picks up oxygen.
4 - The newly oxygen-rich blood (shown in red) returns to the heart and enters the left atrium.
5 - Blood flows through the left atrium into the left ventricle.
6 - The left ventricle pumps the oxygen-rich blood to all parts of the body.
