Take blood away from the heart
Arteries have thick walls and are more elastic than veins
The channel the blood flow enters through (lumen) can widen to allow more blood through
Pulmonary artery is different from the other arteries as it carries deoxygenated blood from the heart too lungs.

Q

4 main characteristics of Capillaries
Name 2

A

Microscopic vessels-impossible to see with naked eye
At one end capillaries carry oxygenated blood which transfers oxyegn and nutrients to the muscles
At the other end deoxygenated blood is carried to the veins and dispose of waste products
Capillaries are also where gaseous exhanges take place

Q

Describe the flow of blood (this is long)

A

Vena cava->right atrium->Triscupid valve-> right ventricle-> semilunar valve->pulomary artery->Lungs-> Blood is now oxygenated->Pulmonary vein->Left atrium->bicuspid valve->left ventricle->Aorta->Body->blood is now deoxygenated
