Which side of the heart receives deoxygenated blood?
Right
What side of the heart receives oxygenated blood?
Left
The pathway of the air through your body?
Mouth or nose, pharynx,larynx,trachea,bronchi, bronchioles, alveoli, blood.
Why are the left side walls thick?
They are thick because it has to pump blood to the body and back again.
The Aorta pumps blood to the….
Body
The blood comes in from the….. side
Left
What blood vessel carries blood away from the heart? Away
Arteries
What blood vessels carry blood to the heart?
Veins
What blood vessel is outside the alveoli?
Capillaries
What is happening in gas exchange?
It is the delivery of oxygen from the lungs to the bloodstream
How does smoking affect your lungs?
Several chest infections. Coughing as well. Also less oxygen reaching the blood stream causing the heart to pump faster
4 chambers
RA
RV
LA
LV
Right side blood flow
The blood comes through the RA then RV then out into the body via pulmonary artery
Left side blood flow
Through LA, through LV through Aorta
Three blood vessels?
Arteries
Veins
Capillaries
The movement of blood starting at the RA
RA, RV, out through pulmonary artery to the lungs, back from the lungs into LA,LV and to the body
What side of the heart receives blood from the lungs?
Left
Which side of the heart receives blood from they body?
Right
What does the diaphragm do?
The main muscle of respiration,
What does the alveoli do?
Gas exchange
what does the larynx do?
Allows air to pass by
Epiglottis
Separates food from liquid
Bronchi
Divides the air into each lung
Bronchioles
Passageways stems
Why is the LV bigger?
It’s bigger because it needs to transport blood all over the body
What texture does the artery have?
Thick and muscular
What texture does a vein have?
Valves
What texture does capillaries have?
Thin and small
Why do we need the Circulatory system?
To supply our cells and blood with oxygen
