Circulatory System
This system’s main job is to send nutrients in blood to the rest of our body.
What is the circulatory system?
This upper chamber of the heart is where blood enters before going to the ventricles.
the atrium
This system’s main function is to supply oxygen and remove carbon dioxide
respiratory system
Blood picks up oxygen in these tiny sacs in the lungs
alveoli
Heart disease can happen when blood vessels that carry blood to the heart get blocked, causing this emergency.
heart attack
These three types of blood vessels make up the circulatory system.
arteries, veins, and capillaries
These two large chambers pump blood out of the heart
ventricles
This muscle below the lungs contracts and relaxes to help with breathin
the diaphragm
This waste gas is carried from the body back to the lungs to be exhaled.
carbon dioxide
his condition occurs when blood pressure against vessel walls is too high
high blood pressure
Arteries carry oxygenated blood in this direction
away from the heart
This valve separates the upper and lower chambers on the right side of the heart
tricuspid valve
The “windpipe” that connects the mouth/nose to the lungs
the trachea
The process of breathing in oxygen is called this
inhalation
This fatty substance can build up and block blood flow to the heart
cholesterol
These tiny blood vessels connect arteries to veins
capillaries
These veins carry oxygenated blood from the lungs to the heart
pulmonary veins
These major airways branch off from the trachea and enter the lungs.
bronchi (bronchus
The process of breathing out carbon dioxide is called this.
exhalation
Nicotine and other chemicals in these products can damage the heart and vessels.
smoking (cigarettes or tobacco
This major blood vessel carries blood away from the heart
the aorta
This artery carries deoxygenated blood from the heart to the lungs
pulmonary artery
This part of the respiratory system contains the vocal cords
the larynx
It takes this long for blood to circulate through your entire body
1–2 minutes
People with this kind of history are at higher risk of heart disease
family history or genetics
