Heart
Blood vessels
blood
Lymph
Lymphatic vessels
glands
What does the circulatory system do?
the system circulates blood & lymph through the body
What does the respiratory system do?
a network of organs & tissues that help you breath
what does the respiratory system consists of?
Airway
lungs
blood vessels
Muscles that power your lungs
The things in the respiratory system work together for what?
work together to move 02 thought the body & clean out waste gases such as CO2
Blood components are?
Plasma
Buffy coat
Red blood cells
4 main components?
Plasma
Red blood cells
White blood cells
Platelets
Plasma
recovers injuries
Distributes nutrients
removes waste
prevents infections Is a liquid component
Red blood cells
Carries O2 from lungs & CO2 is exhaled
White blood cells
Part of the immune system
Protect from infections by attacking the unknown cells
Platelets
Small, colourless cell fragments
forms clots & stops or prevents bleeding made in the bone marrow
Antigens
any substance that causes the body to make an immune response against that substance
Antibodies
a protein produced by the body's immune system when it detects harmful substances
What are the blood types
A + - B + - AB + - O + -
What is the most common blood type?
O +
What is the rarest blood type?
AB -
What blood type is a universal donor?
O -
What blood type can receive blood from any other blood type
AB +
What is Rhesus Factor
A protein that is present or absent on the surface of red blood cells. if is it there then the person is Rh + but if not than they are Rh -
What Rh is most common?
Rh +
Haemolytic anemia
Rh antibodies that attack the baby's red blood cells faster than it can make new ones
Rh immunoglobin
Protein that prevents the expecting mother from producing Rh antibodies
Factors that stop people from being able to donate blood?
Being under 17
Being pregnent
Tattoo in the last 3 months
under 110lbs
HIV +
Blood Vessels
Distributes blood through channels, to body tissues
Vessels make up two closed systems of tubes that begin & end at the heart
What are the 2 closed systems & what are the different blood vessels?
The Pulmonary system & the systemic system
Arteries
Arterioles
Capillaries
Veins
Venules
The Pulmonary System
Transports blood from heart to the lungs & back to the heart
The Systemic System
Carries blood from the heart to the tissues in all parts of the body & then returns the blood to the heart
Arteries
Blood vessels which carry blood away from the heart to various parts of the body
Larger arteries branch into many tiny arteries
Largest Artery in the body?
Aorta
Smallest Artery in the body?
Arterioles
Veins
Blood vessels which carry blood to the heart from various parts of the body
What type of walls do veins have & why?
Walls are thinner & less rigid so that they can hold more blood
Cappilaries
They transport blood, nutrients and oxygen to cells in your organs and body systems
What type of walls do Capillaries
Has very thin walls, Arterioles branch into a network of capillaries.
What do the capillaries do?
Exchange between the blood & the cells of the body take place.
The blood is gives up it's O2 & takes on CO2
Where do capillaries reunite?
venules which going to larger & larger veins
Venous Valves
The pumping action of the heart causes blood to be forced from the arteries to the capillaries
Since veins work against gravity they have a pumping system to make sure the blood can make a return trip
Why do venous valves happen?
No idenified cause but could be if
Old age
Female
over weight
Genetics
Draw open and closed Venous valves

What is similar & different about antigens & antibodies
What antigens & antibodies do A Blood type have?
Anti A Compatible with: A & O Antibodies against: Anti B
What antigens & antibodies do B Blood type have?
Anti B Compatible with: B & O Antibodies against: Anti A
What antigens & antibodies do AB Blood type have?
Anti A & B Compatible with: A, B & O Antibodies against: none
What antigens & antibodies do O Blood type have?
No Antigens Compatible with: O Antibodies against: A & B
How does Rh factor effect pregnancy?
The mother is Rh - & the baby is Rh + therefore mother releases antigen d & will attack baby.
3 main blood vessels in the circulatory system?
Arteries
Veins
Capillaries
What is diffusion & how does it relate to the circulatory system?
The movement of molecules from a high to low concentration. Diffusion is needed for the passing of O2 & the exchange of CO2
