- Blood
- Red Blood
Cells
- Are made in bone
marrow of long bones.
- Carry oxygen and transport
nutrients and waste products.

- White Blood
Cells
- Are made in bone
marrow and lymph tissue.
- Protect the body
from disease.

- Platelets
- In charge of blood clotting
- Clotting is important to stop
blood loss from the body and
stop internal bleeding.

- Plasma
- Made up of mostly
water and makes up
55% of volume of
blood, which helps
blood fluidity.

- Red Blood
Cells
- Heart
- Inferior Vena Cava
- Superior Vena Cava
- Pulmonary Valve
- Right Atrium
- Tricuspid Valve
- Right Ventricle
- Myocardium
- Septum
- Left Ventricle
- Mitral Valve
- Aortic Valve
- Left Atrium
- Pulmonary Artery
- Aorta
- Inferior Vena Cava
- Blood Vessels
- Arteries
- Have thick flexible
vessel walls, it has a
pulse and no valves.
- It works under high
pressure, it has a narrow
lumen and it transports
blood away from the heart
(oxygenated).

(oxygenated).
- Have thick flexible
vessel walls, it has a
pulse and no valves.
- Veins
- Have thin walls, they have valves
present (this prevents back flow),
they also have no pulse, but they
do have pulsating muscles close
to the veins which help to prevent
back flow (skeletal pump).
- They work under high
pressure, they have a wide
lumen and they transport
blood towards the heart
(deoxygenated).

do have pulsating muscles close
to the veins which help to prevent
back flow (skeletal pump).
- Capillaries
- Have the smallest of all the
vessels, as the walls are only
one cell thick and they are 'semi
permeable', which means they let
some substances through.
- At one end they
feed muscles,
organs and body
tissue with oxygen
and nutrients and
at the other end,
carbon dioxide and
waste products
pass into the veins
to be removed.
They also bring
blood within reach
of every cell.

- Arteries
- The Flow
of Blood
- De-oxygenated blood
returns to the heart
through the large veins
called 'Vena Cava.'
- Blood enters the 'Right
Atrium' and passes through
the 'Tricuspid Valve' into
the 'Right Ventricle'.
- It is then pumped through the 'Semi-Lunar Valve'
into the 'Pulmonary Artery' and into the lungs, where
it loses carbon dioxide and picks up fresh oxygen.
- Oxygenated blood returns to the heart from the lungs
through the 'Pulmonary Vein' into the 'Left Atrium'.
- It passes through 'Bicuspid Valve'
and into the 'Left Ventricle'.
- It is then pumped through the 'Semi-Lunar
Valve' into the 'Aorta' and out to the rest of
the body through the 'Arteries'.
- It then goes from this
step back to the first
one, to then repeat the
whole cycle again.
