What is the name of the area of the heart that on the diagram is in the top left
right atrium
What is the name of the area of the heart that on the diagram is in the bottom left
right ventricle
What is the name of the area of the heart that on the diagram is in the top right
left atrium
What is the name of the area of the heart that on the diagram is in the bottom right
left ventricle
what is the name of the part of the heart that on the diagram is the tube that comes out of the top to the left
pulmonary artery
what is the name of the part of the heart that on the diagram is the tube that comes out of the top to the right
aorta
name the chambers of the heart
L&R atrium, L&R ventricle, aorta, pulmonary artery
Name the 4 components of blood
plasma, red blood cells, white blood cells, platelets
Which part of blood is a pale yellow liquid?
Plasma
Which part of blood clump together to form clots?
platelets
What is the red pigment found in red blood cells called and what does it do?
haemoglobin, carries oxygen in red blood cells
Which part of blood transports carbon dioxide?
plazma
Where does the heart pump blood to?
Right side:
Left side:
Right side: lungs
Left side :around body
Name 3 types of blood vessel
arteries, veins, capillaries
what are the features of arteries
thick elastic walls, carries blood away from heart at high pressure
what are the features of veins
low pressure, carrys blood to heart , valves ,thinner walls
what are the features of capillaries
thin walls (1 cell thick) low pressure, narrow, delivers blood to cells
Which blood vessels carry blood away from the heart?
arteries
Which blood vessels carry blood towards the heart
veins
Why do arteries have strong walls?
because the blood is at high pressure
What is the coronary artery?
artery that supplys heart muscle with oxygen
Why does the heart need its own blood supply?
cardiac muscle needs oxygen
Why do arteries have elastic walls?
to come with high pressure
How is blood kept moving in the large veins of the legs?
muscle push against veins to help squeeze blood to heart (valves stop blood going backwards)
what’s the name of the indicator that was used to test respiration
biocarbonate indicator
what colours is biocarbonate indicator in what environments
decreased levels of carbon dioxide : purple
normal levels of carbon dioxide : dark red/orange
increased levels of carbon dioxide : yellow
what is plaque made of
cholesterol
what is plaque
fatty patches that form inside arteries, they can cause heart disease
what are the consequences of heart disease
heart attack
