  • Tunica intima
  • Tunica media
  • Tunica externa

Pregunta 2

Pregunta
What is this part of the vein called?
Respuesta
  • Lumen
  • Tunica intima
  • Tunica media
  • Tunica externa

Pregunta 3

Pregunta
Blood go away from the heart through the [blank_start]arteries[blank_end], blood goes back to the heart through the [blank_start]veins[blank_end]
Respuesta
  • arteries
  • veins

Pregunta 4

Pregunta
The largest arteries divide into smaller ones called [blank_start]arterioles[blank_end], then divide into [blank_start]capillaries[blank_end], which then join up to form [blank_start]venules[blank_end] which finally merge to form [blank_start]veins[blank_end]
Respuesta
  • arterioles
  • capillaries
  • venules
  • veins

Pregunta 5

Pregunta
The inner layer of blood vessels ([blank_start]tunica[blank_end] [blank_start]intima[blank_end]) is a thin layer of [blank_start]elastic[blank_end] tissue allowing it to [blank_start]stretch[blank_end]
Respuesta
  • tunica
  • intima
  • elastic
  • stretch

Pregunta 6

Pregunta
The middle layer of blood vessels ([blank_start]tunica[blank_end] [blank_start]media[blank_end]) contain [blank_start]smooth[blank_end] muscle and [blank_start]elastic[blank_end] fibres
Respuesta
  • tunica
  • media
  • smooth
  • elastic

Pregunta 7

Pregunta
The outer layer of blood vessels ([blank_start]tunica[blank_end] [blank_start]externa[blank_end]) contain [blank_start]collagen[blank_end] and [blank_start]elastic[blank_end] tissue
Respuesta
  • tunica
  • externa
  • collagen
  • elastic

Pregunta 8

Pregunta
Arteries are lined with [blank_start]squamous[blank_end] cells so it is a very [blank_start]smooth[blank_end] surface
Respuesta
  • squamous
  • smooth

Pregunta 9

Pregunta
Arterioles contain more [blank_start]smooth[blank_end] [blank_start]muscle[blank_end] which allows them to [blank_start]vasoconstrict[blank_end] and [blank_start]vasodiolate[blank_end]
Respuesta
  • smooth
  • muscle
  • vasoconstrict
  • vasodiolate

Pregunta 10

Pregunta
The lumen of capillaries are very [blank_start]narrow[blank_end] so there is a small [blank_start]diffusion[blank_end] [blank_start]pathway[blank_end]
Respuesta
  • narrow
  • diffusion
  • pathway

Pregunta 11

Pregunta
The walls of capillaries are [blank_start]porous[blank_end] so [blank_start]plasma[blank_end] and disolved substances can leave the blood
Respuesta
  • porous
  • plasma

Pregunta 12

Pregunta
Blood flows towards the heart [blank_start]opening[blank_end] the valve and if blood flows away from the heart, the valve [blank_start]closes[blank_end], preventing [blank_start]backflow[blank_end]
Respuesta
  • opening
  • closes
  • backflow
