- two cell layers – _______________________________
Endoderm has _____________________________
- use ________ and ____________ to move materials then
cyclosis inside the cells

What happens to the
digested materials in
the gastrovascular
cavity?
What about the
undigested materials?
What is the link

transport?

________________________
e) _________________________

4. Transport in the Grasshopper
a) _________________________
- blood is ____________________________

___________________________
b) ______________
- colorless – _______________________
- ___________________________________
- used to transport ____________________________
c) _________________
- _________________
- pumps blood out the ______________
- blood is also moved by _______________________
- _________ – stop the ________________________
d) ______________
- blood vessel that ______________________________
- blood flows out of the aorta ______________________
spaces and finally _______________________________
B. Human Circulatory System
1. _______________
- blood contains both dissolved substances and specialized
cells
- humans have ~ 5 L of blood
- Blood is composed of 4 different parts
a) ______________________________________________
- most numerous cell in the body
- __________________
- ____________ = _______ on RBC used to ___________
________________________
- made in _______________ – on the end of long bones
- mature red blood cells do not have nuclei become filled
with hemoglobin
- live for ~ 120 days
- destroyed by liver
and spleen
b) _________________________________________
- ________________________________________
- made in red bone marrow and lymph nodes
- attack _________________ and organisms cancer cells,
transplants, allergens, virus, bacteria
- ______ in number when the body is ________________
c) ___________________
- cell fragments  made in bone marrow
- involved in __________  combine with blood proteins to
stop bleeding
d) ___________________
- yellow _______________ of blood  makes up 55% of
blood
- 90% water
- 10% dissolved _____, _____, _____________________
________________, _______, ________, ___________
_______________, and ___________________
2. Blood Vessels
a) ____________
- thick walled large muscular blood vessels
smooth muscle – like digestive system
- carry blood __________________________
- generally carry _______________________
except for the __________________ – deoxygenated
- under large amounts of _________________
- feel the __________________
- _________ = largest artery
b) _______________
- thinner and less muscle than arteries
- carry blood __________________________
- generally carry ____________________________
except for ____________________ - oxygenated
- contain one way _____ to keep blood flowing in one
direction
- blood flow is helped by skeletal muscle
Valve Animation
c) _________________
- site where ______________________________________
__________________________
- _______________________________________________
- blood passes through 1 cell at a time – single file
3. _________________
a) Structure
- _________ organ with thick muscular walls
- myocardium - muscle = _____________________
* specialized muscle tissue
Make a fist demo
- the heart is divided into _____________________
* ____________ = upper chamber (left and right)
* ____________ = lower chamber (left and right)
pumps blood out of the heart
- divided into the _____
and ______ sides by the
_________
prevent the mixing of
blood
right side –
_________________
left side – _________
_______________
b) Blood Flow Through the Heart
- acts as _________________
- 1 pump - right side – ___________________ pumps to the
lungs
- other pump – left side –
______________ pumps
to the body
- Atria  Valve 
Ventricle  Artery
right side - tricuspid valve
left side - bicuspid valve
c) Blood Circulation
- _____________________
- circulation to the lungs
________________________
________________________
____________  ___________
- Systemic Circulation
- circulation to the body renal,
hepatic, neural, etc.
oxygen leaves the blood,
carbon dioxide enters
___________  ____________
Blood returns to the heart through the
__________  _____________  _______________ 
_____________  _____________ 
_____________ _____________ _____________– the
_____________ _____________ 
_____________  ____________ ___________ ____
_____________  _____________  _____________ 
_____________ _____________ _____________ – the
_____________ _____________ 
_____________  _____________– to do it all again!
Heart  Lungs  Heart  Body
it takes ~7 minutes for a red blood cell to complete the trip
d) Heart Rate / Heartbeat
- heart has its own “pace maker” – bundle of nerves to
control and time the rhythm of the beats
- sinoatrial node (SA) – causes atria to beat first
