Circulatory System Flashcards
What is the role of the circulatory system?
- Provide cells in the body with oxygen and nutrients
- Remove the cells wastes like toxins and co2 carbon dioxide
SM AP TXT BK
- All cells in the body need to have oxygen and nutrients, and they need their wastesremoved. These are the main roles of the circulatory system.
- The heart, blood and blood vessels work together to service the cells of the body. Using the network of
arteries, veins and capillaries, blood carries carbon dioxide to the lungs (for exhalation) and picks up oxygen. From the small intestine, the blood gathers food nutrients anddelivers them to every cell.
What does the heart do?
The heart pumps blood around the body.
Where is the heart?
It sits inside the chest, in front of the lungs
and slightly to the left side.
HOw many chambers in the heart double pump?
four
SM AP TXT BK
The heart is a double pump made up of four chambers,
with the flow of blood going in one direction due to the presence of the heart valves.
what makes the sound of heart beats
The contractions of the chambers make the sound of heartbeats.
What does the right side of the heart do?
(upper right chamber (Atrium)
(lower right chamber(Ventricle)
- the upper chamber takes in deoxygenated blood w/co2 CD
- squeezes it to the lower chamber (ventricle)
- artery to lungs takes co2 and replaces it with oxygen
SM AP TXT BK
The right side of the heart; The right upper chamber (atrium) takes in deoxygenated blood that is loaded with carbon dioxide. The blood is squeezed down into the right lower chamber (ventricle) and taken by an artery to the lungs where the carbon dioxide
is replaced with oxygen.
What does the LEFT side of the heart do?
(upper LEFT chamber (Atrium)
(lower right chamber(Ventricle)
- oxygenated blood enters left upper chamber (atrium) pumped to left lower chamber (ventricle)
then to aorta (an artery0
then blood starts journey around body again
SM AP TXT BK
The left side of the heart; The oxygenated blood travels back to the heart, this time entering the left upper chamber (atrium). It is pumped into the left lower chamber (ventricle) and then into the aorta (an artery). The blood starts its journey around the
body once more.
Blood vessels have a range of different sizes and structures, depending on their role
in the body TURE OR FALSE?
TREUE Blood vessels have a range of different sizes and structures, depending on their role
in the body
Ateries are muscular, T or F?
True
SM AP TXT BK
- Arteries; Oxygenated blood is pumped from the heart along arteries, which are muscular. Arteries divide like tree branches until they are slender. The largest artery is the aorta, which connects to the heart and picks up oxygenated blood from the left ventricle. The only artery that picks up deoxygenated blood is the pulmonary artery, which runs between the heart and lungs.
Oxygenated blood is pumped from the heart along arteries true or false?
true
Arteries divide like tree branches until they are slender. true or fals?
true
which is the largest artery?
Aorta
what does the aorta connect to?
the heart - the aorta picks up oxygenated blodd from the left ventricle (lower chamber of heart)
which artery pick up deoxygenated blood?
PULMONARY ARTERY
The only artery that picks up deoxygenated blood is the pulmonary artery,
which runs between the heart and lungs.
Where is the pulmonary artery?
PULMONARY ARTERY runs between the heart and lungs.
What are Capillaries?
- the smallest blood vessels
SM AP TXT BK
Capillaries; The arteries eventually divide down into the smallest blood vessel, the
capillary.
-Capillaries are so small that blood cells can only move through them one at
a time. Oxygen and food nutrients pass from these capillaries to the cells.
-Capillaries are also connected to veins, so wastes from the cells can be transferred to the blood.
how many blood cells can move through a capillary at a time?
one
What passes through capillaries (smallest blood vessels) to the cells?
- oxygen
- food nutrients
- wastes from cells - then transferred to blood
Where does the blood gather food nutrients from to deliver to the every cell?
From the small intestine, the blood gathers food nutrients and delivers them to every cell.
Veins have one way valves instead of muscles to stop the blood running back the wrong way, T/F?
TRUE
SM AP TXT BK
- Veins have one-way valves instead of muscles, to stop blood from running back the wrong way. Generally, veins carry deoxygenated blood from the body to the heart,where it can be sent to the lungs.
- The exception is the network of pulmonary veins,
which take oxygenated blood from the lungs to the heart
What do most veins carry from the body to the heart for it to send to the lungs?
Veins take DEOXYGENATED blood
FROM body
TO heart
THEN from heart
TO lungs
Generally, veins carry deoxygenated blood from the body to the heart, where it can be sent to the lungs.
What is the exception? Which network of veins take oxygenated blood from the lungs to the heart to be pumped around to the cells?
Pulmonary VEINS, take OXYGENATED BLOOD from the lungs to the heart
Pulmonary veins take
Oxygenated blood
FROM lungs
TO heart

ARTERIES carrying blood AWAY FROM HEART
VEINS carrying blood back TO HEART
carbon dioxide and oxygen both pass through the heart
Using the network of:
-arteries, veins and capillaries, blood carries carbon dioxide to the lungs (for exhalation)
and picks up oxygen.
- From the small intestine, the blood gathers food nutrients and delivers them to every cell.
How can Yoga strengthen Circulatory System?
Yoga strengthens Circulatory System:
- Giving veins a break/help to push blood back up to heart via the skeletral muscles
- Using inversions, legs up wall, Sunsals, Pranayama
Which Blood Vessels do what?
To/From
Arteries = Blood vessels take O2&Nutrients TO the body/Away from heart
Veins = Blood vessels take Co2&Waste FROM the body/TO Heart
Arteries (in red) are the blood vessels that deliver blood to the body. Veins (in blue) are the blood vessels that return blood to the heart.30 Apr 2019

- Heart is pumping blood
- Blood vessels carrying blood
- Blood is either rich with nutrients and oxygen
OR - Carbon dioxide and waste
- Transport these things so that every cell is either GETTING what it needs or getting RID of rubbish.
- Arteries = Blood vessels take O2&Nutrients TO the body/Away from heart.
- Veins = Blood vessels take Co2&Waste FROM the body/TO Heart.
Arteries - thick smooth muscles/autonomic/away from heart
Veins - thinner/trap doors/valves/rely on our movement and skeletal muscles to help move blood/blood back to heart
Capillaries – 1 cell thick, tiny/oxygen diffuse from cell AND carbon dioxide can diffuse back into the bloodstream
Name the Two Parts Of Circulation?
Two Parts Of Circulation
- Between Heart and Lungs/PULMONARY CIRCULATION
- Between Heart and Body/SYSTEMIC CIRCULATION
The word pulmonary means?
The word pulmonary means “pertaining to the lungs.” It is derived from the Latin root word pulmo, which means lung. If someone has pulmonary disease, this means they have a lung disease
Which side of the heart pumps what?
LFT - pumps oxygenated blood to organs
RT - pumps deoxygenated blood to lungs
The heart
The heart is a unidirectional pump.
Valves are present to prevent the backflow of blood.
The right side pumps deoxygenated blood (low in oxygen and high in carbon dioxide) to the lungs.
The left side pumps oxygenated blood (high in oxygen and low in carbon dioxide) to the organs of the body.
Explain Circulation Process GOOGLE
Google:
Deoxygenated blood enters the right atrium from the vena cava.
Blood moves into right ventricle.
Blood is pumped into the pulmonary artery.
The pulmonary artery carries deoxygenated blood to the lungs.
The blood becomes oxygenated in the lungs.
Oxygenated blood leaves the lung via the pulmonary vein.
Blood enters the left atrium.
Blood moves into the left ventricle.
Blood is pumped into the aorta, which carries oxygenated blood around the body.
This means blood travels through the heart twice in one circulation of the body.
veins to heart
ateries away form heart
Great ways to increase the effectiveness of respiration and circulation is thorugh:
Asana
Pranayama
So that you can flood the body with oxygen and nutrients
