16
Q
Identify structure
A
Lymph node
17
Q
- Identify structure
- Name at least 3 histological details
A
- Lymph node
- histological details:
- Lymphoid follicles
- cortex,
- germinal center (contains lymphocytes),
- medulla, medullary cords, lymphatic vessels
18
Q
- Identify the structure
- What is the name of the structure at the tip of the pointer?
A
- Spleen
- White pulp
20
Q
Identify at least 2 structures
A
- Artery
- Vein
21
Q
- Is this an artery or a vein?
- Name the structures labeled as A, B and C
A
- An artery
- The tunica intima (A) = is simple squamous epithelium.
- Tunica media (B) of smooth muscle and various amounts of elastic connective tissue.
- The tunica externa (C)
22
Q
- Is this an artery or a vein?
- Name the structures labeled as A, B and C
- Artery and vein size comparison
A
- Vein
- A, B, C
- Thin tunica media (B) of smooth muscle.
- The tunica intima (A) is simple squamous epithelium.
- The tunica externa (C) is often difficult to detect. Venules are smaller versions of a vein.
- If an artery and vein of the same size are compared, the lumen of the vein would be larger and its tunica media thinner.

A
hyaline cartilage
29
Q
What type of tissue is this in the trachea and its function?
A
- Ciliated Pseudostratified columnar epithelium with goblet cells
- Function: Windpipe
- Goblet cells secrete mucus
- Cilia sweeps mucus and dirt out of the lungs
30
