(a) Merocrine gland
Cells of the gland produce secretions by
active transport or produce vesicles that
contain secretory products, and the vesicles
empty their contents into the duct through
exocytosis.
(b) Apocrine gland
Secretory products are stored in the cell near
the lumen of the duct. A portion of the cell
near the lumen containing secretory products
is pinched off the cell and joins secretions
produced by a merocine process.
(c) Holocrine gland
Secretory products are stored in the
cells of the gland. Entire cells are shed
by the gland and become part of the
secretion. The lost cells are replaced
by other cells deeper in the gland.

Splinter
Bacteria
introduced 1
A splinter in the skin causes damage and
introduces bacteria. Chemical mediators of
inflammation are released or activated in injured
tissues and adjacent blood vessels. Some blood
vessels rupture, causing bleeding. 1
Epidermis 2
Chemical mediators cause capillaries to dilate
and the skin to become red. Chemical mediators
also increase capillary permeability, and fluid
leaves the capillaries, producing swelling
(arrows). 2
Dermis
Blood

Bacteria
proliferating 3
White blood cells (e.g., neutrophils) leave the
dilated blood vessels and move to the site of
bacterial infection, where they begin to
phagocytize bacteria and other debris. 3

Fresh wound cuts through the epithelium (epidermis)
and underlying connective tissue (dermis), and a clot
forms. 2
Approximately 1 week after the injury, a scab is present,
and epithelium (new epidermis) is growing into the wound.

Approximately 2 weeks after the injury, the epithelium
has grown completely into the wound, and fibroblasts
have formed granulation tissue. 4
Approximately 1 month after the injury, the wound has
completely closed, the scab has been sloughed, and the
granulation tissue is being replaced by new connective
tissue.
