The Circulatory System
(Cardiovascular)
Cardiovascular System

Includes your heart, blood and vessels

Bring Oxygen and Nutrients to the body
and removes waste.
HEART

Made of cardiac muscle
– a. Right atrium – receives blood from whole
body
– b. Left atrium
 Receives blood from lungs
– c. Right ventricle –
 pumps blood to lungs
– d. Left ventricle
 Pumps blood to the body
Heart

Valves – one way and separate the atrium
from ventricle to prevent blood backflow

The wall separates the two sides of the
heart to prevent OXYGENATED blood from
mixing with deoxygenated blood.

Types of Circulation

Coronary – to and from the heart

Pulmonary – to and from lungs

Systemic – to and from the body
Blood vessels

Artery – takes blood away from heart
(red)

Vein – takes blood to the heart. (blue)

Capillaries – microscopic vessels where
arteries and veins meet (purple)
Parts of Blood

White blood cells – fights infection

Red blood cells – carry oxygen


Platelets – clot the blood

Plasma – nutrients and minerals
