Why do we have a circulatory system?
What are the main structures of the circulatory system?
What is in blood?
How does the circulatory system work (be sure to be specific about what the heart does too)?
How does the circulatory system work with other systems?

1)the circulatory system is present in our human bodies for the flow of oxygen through our body for respiration of cells

2)the main structures are

a)the blood vessels :

used for transport of blood with and without oxygen

b)the. blood :

it is the red fluid which contains the oxygen and is able to transport it

c)the heart it is used to pump the blood to through the body

3) blood is a red fluid containing of red blood cells ,white blood cells,plasma,platlets

a)red blood cells is used to transport oxygen

b) white blood cells is used to protect us from viruses

c) it is the liquid part which helps everything flow

d) it is used for sealing up injuries

4)blood is flown trough the veins and arteries until it reaches the heart and from there it is pumped to the lungs where it is oxygenated and goes trough the body

5)the circulatory system works with the respiratory system by taking oxygen from it and then passing it trough the body

pls gimme brainliest It took soon much time typing this

the right side of the picture going down is:

polymerase

protein

transport vesicle

modified protein

the left side of the picture going down is:

dna helix

single-stranded rna

endoplasmic reticulum

ribosome

golgi apparatus

protein released from vesicle

click to let others know, how is it
