Resource summary
Transport in animals
the circulatory system
multicellular organisms need transport systems
relatively large = low surface area to volume ratio
diffusion isn't efficient enough
very active
large no. cells respiring quickly = need a constant, rapid supply of glucose and oxygen
Diffusion isn't efficient enough
cannot supply cells in centre fast enough using diffusion
systems
single circulatory system
FISH
gills
heart
rest of body
gills
only pass through heart once
double circulatory system
pass through heart twice
MAMMELS
heart
lungs
heart
PULMONARY LOOP
body
SYSTEMIC SYSTEM
open circulatory system
blood isn't always enclosed in blood vessels
flows freely through the body cavity
INSECTS
HEART
main artery
body cavity
blood flows around insects organs
heart
closed circulatory system
blood enclosed inside blood vessels
FISH
arteries
capillaries
veins
heart
substances - glucose and oxygen- diffuse
body cells
heart basics
structure
septum
separates ventricles
oxygenated and deoxygenated blood separated
valves
tendinous cords
attach valves to walls
prevent valves from turning inside out
AV valve
fill up, then pour into ventricles when it contracts
atrial contraction - valves open
bp in atria higher than bp in ventricles
ventricular contraction - valves clolse
bp in ventricles higher than bp in atria
SL valve
base of major arteries
prevents backflow as ventricles relax
fill w/blood then shut
atria
ventricles
thinner muscle
only transfer blood to ventricles
ventricles
right
lungs
thinner wall than left
high pressure could easily burst the capillaries
left
wall x2-3 thicker than right
higher blood pressure to overcome the resistance of systemic circulation
electrical activity of the heart
blood vessels
tissue fluid
formed from blood
forms lymph
surrounds cells in tissue
capillaries
single cell wall
decreased diffusion gradient
veins
arteries
coronary arteries
lie over surface of heart
carry oxygenated to heart
constricted
reduced blood flow to heart
reduce oxygen to heart
angina/ heart attack
lymph vessels
haemoglobin
structure
4 polypeptide chains
haem group
iron
the bohr shift
actively respiring tissue = need more oxygen
move curve to RIGHT
decreased affinity for oxygen
fetal haemogolobin
placenta = lower ppO2
must be able to saturate its haemoglobin w/ oxygen
must have higher affinity for oxygen
move curve to LEFT
