Oxygenated blood flows from the?
lungs through the heart to the body
Deoxygenated blood flows back from?
the body through the heart to the lungs
the heart is made up of 4 chambers?
2 atriums and 2 ventricles
The atrium gather blood from
the body or lungs
the ventricles pump the blood to the
body or lungs
valves prevent the
backflow of blood
the valves are found between the
atrium and ventricle and ventricle and artery
The two artertys
aorta and pulmonary artery
the two veins
vena cava and pulmonary vein
as the aorta comes out of the heart it splits off into smaller?
arteries to go to the main organs
three types of blood vessels
artery, vein, capillary
The coronary arteries supply
the heart muscle with oxygenated blood
blood from the heart gets around the body through
blood vessels
Arteries
carry blood away from the heart
the veins
carry blood towards the heart
capillaries link arteries with
veins
the capillaries walls are
only one cell thick
White blood cells
defends the body against diseases
red blood cells
contain red pigment (hemoglobin) which transports oxygen around the body
Plasma
yellow fluid that contains the blood cells, glucose and CO2
Platelets
clot blood, form scabs and stopping bleeding
Phagocytes carry out
phagocytosis by engulfing anf destroying pathogens
Some lymphocytes produce
antibodies which destroy pathogens
Four features of a red blood cell
has a biconcave shape for gas exchange
has a large surface area
jas no nucleus so more space for hemoglobin
contains haemoglobin
