continuous capillary

2

Key features of continuous capillaries: 

  • tight junctions;
  • Pinocytotic vesicles (transcytosis) enable substances to pass from the lumen to the CT

3

Are capillaries surrounded by smooth muscle?

No

4

lymph vessels (lacteals)

10

Do lymph vessel lumens contain blood cells?

No

11

Identify:
