Soc 16- The Structure Of The Blood Vessles And Blood Distrubution Flashcards
Veins
Carry deoxygenated blood back into the heart
Veins 4 characteristics
Veins carry blood into the heart
Veins have much thinner walls
Veins contain many valves
Pulmonary veins carry oxygenated blood
Why is the pulmonary vein is different to other veins
As it carries oxygenated blood from the lungs back to the heart
Why do veins contain many valves
helps deoxygenated blood flow to the heart
Arteries 4 main characteristics
Arteries takes deoxygenated blood away from the heart
Arteries have thick walls
The pulomnary artery carries deoxygenated blood from the heart to lungs
They channel the blood flows through called the lumen can widen to allow more blood through to the working muscles
Whats the name of the channel that blood travels through in order to reach the working muscles
Lumen - can widen to allow more blood through so when you exercise it can reach the working muscle.
How is the pulmonary arterie different from other arteries
It carries deoxygented blood from the heart to the lungs
4 main characteristics of the Capillaries
Microscopic vessle- one cell thick
At one end the capillaries carry deoxygenated blood which transfers oxygen and nutrients to muscles
Capillaries are where gaseous exchange takes place
Capillaries carry deoxygenated blood into the veins, picking up waste products and taking them around the body to dispose of them
How thick are the Capillaries vessles
Microscopic just one cell thick
Immune system
The structures and process in your body that stop diseases
Thrombokinase
Substance involved in blood clotting process
Plasma
The fluid part of blood
Erythrocyte
Red blood cell
Haemogoblin
A red protein in the blood that transports oxygen
Anaemia
A condition where there is a lack of red red cells or haemogoblin in the blood
