Study Notes
- Blood consists of plasma, red blood corpuscles (erythrocytes), leucocytes, and blood platelets.
- Blood is a connective tissue.
- Blood consists of plasma and formed elements.
- Red blood corpuscles are also called erythrocytes.
- White blood cells are also called leucocytes.
- The second image shown is for a monocyte.
- Any blood vessel has three layers: tunica intima, tunica media, and tunica adventitia.
- Tunica intima is the innermost layer.
- Tunica media is the middle layer.
- Tunica adventitia is the outermost layer.
Aorta
- Tunica intima is ill-defined from media and has no apparent internal elastic lamina.
- Tunica media has a characteristic large amount of fenestrated elastic membranes.
- Tunica adventitia is relatively thin.
Inferior Vena Cava
- It has a relatively larger lumen and a much thinner wall than the aorta.
- Bundles of smooth muscle fibers are present in the media.
- The most prominent thick adventitia consists of longitudinally arranged bundles of smooth muscle fibers.
