chapter 10- Integumentary and immune system Flashcards
most of the blood supply to the skin and most of the specialized cells are in which layer of the skn
dermis
which layer of the skin contains keratinocytes, corneocytes
epidermis
function of cornoeocytes
protective waterproof cells that don’t undergo further replication and are routinely sloughed off and replaced
what does inflammation do to the blood vessels
dilate and increase permeability of blood vessels
granuloctyes
leukocyte, attached to site of injury where they phagocytize antigens and antigenic material
neutrophils
granulocytes, most common, first responders, phagocytic
eosinophils
granulocytes, fight parasites, mediate allergic response
basophil
least common granulocyte, fight parasites and mediate allergic response
APCs family
macrophages, dendritic cell and B lymphocytes
monocytes
long live immune cells that differentiate into macrophages and dendritic cells
macrophage
phagocytic; secrete cytokines; present antigens
dendritic cells
present antigens; active immune system
- in parts of body that contacts external environment
cell mediated immunity
- adaptive immunity
- mediated by T lymphocytes
what kind of cells does the MHCI come from
cells infected with viruses developing tutors and signals Tc cells to destroy those cells
-cytotoxic T cells
what kind of MHCII
-T helper (TH) cells
