Artery
Carry blood away from the heart (always oxygenated apart from the pulmonary artery which goes to the lungs). Have thick muscular walls - to withstand pressure. Have small passageways for blood (internal lumen) Contain blood under high pressure
1 of 13
Vein
Carry blood to the heart (always de-oxygenated apart from the pulmonary vein which goes from the lungs to the heart). Have thin walls Have larger internal lumen. Contain blood under low pressure .Have valves to prevent blood flowing backwards
2 of 13
Capillaries
Found in the muscles and lungs. Microscopic – one cell thick .Very low blood pressure .Where gas exchange takes place. Oxygen passes through the capillary wall and into the tissues, carbon dioxide passes from the tissues into the blood

why does the Heart Pump
The heart is made to pump by little pulses of electricity from the wall of the right atrium
4 of 13
Red blood cell
Contain haemoglobin which carries oxygen.Made in the bone marrow. The more you train the more red blood cells are made. Have no nucleus to allow more space for oxygen Biconcave disc shape - greater surface area and allows cell to move through small s
5 of 13
White blood cells
Protect the body by fighting disease
6 of 13
Plasma
Fluid part of blood which carries carbon dioxide, hormones and waste Platelets
7 of 13
Platelets
Clump together to form clots. Protect the body by stopping bleeding
8 of 13
Bicuspid valve
The valve between the left atrium and left ventricle
9 of 13
Tricuspid valve
The valve between the right atrium and ventricle
10 of 13
Heart tendons/heart strings
are attached to the valves and stop them flipping inside out
11 of 13
Septum
Muscular wall between the right and the left of he heart
12 of 13
Semi lunar valves
the valves between the right ventricle and the pulmonary artery
