Arteries and veins slides
For microscopic histology slides, be able to recognize an
artery and distinguish it from a vein.
(Look for the dark-staining elastic fibers
around the lumen of the thick wall of the artery versus the
thinner, collapsed wall of the vein.)
Be able to explain how you were able to identify an
artery or a vein.
Your lab manual shows a cross section of an
artery and a vein.
- The lumen is in the upper left corner.
- The dark layer
outside it is elastic tissue layer.
- The thick pink layer
is the thick muscular wall.
(Note how the muscular layer shows striations).
- The walls of the veins are
relatively thin compared to the size of the lumen.
- The walls of the veins tend to collapse
when a slide is prepared.
- You can see remnants of blood in the lumens of the veins.
Circulatory model pictures
Be able to identify these arteries and veins in the models:
- subclavian veins
- jugular veins
- superior vena cava
- inferior vena cava
- iliac veins
- renal vein
- hepatic portal vein
- splenic vein
- median cubital vein
- basilic vein
- cephalic vein
- great saphenous vein
