Flashcards: Histology lecture 10

Disc shape: Lack of organelles or nucleus occurs during cell development- important for the exchange of gas - provides more space due to bi-concave of shape.

Blood cells that have specs: bloods cells that have not completely been broken-down.

Nonmammals: typically elliptical-shaped (elliptocytes)

round to oval, heterochromatic, centrally placed

Circulate for 5-6 days 40% stored in spleen

Distinguishing of different blood stains.

As granules mature they are able to attack specific pathogens in Eosinophil (granules are less specific in marrows)

Non-segmented nucleus: lobed deeply indented: they become macrophage

Elicited: Phagocytes or breakdown cells that have died and need to be broken-down.

round in shape (relate to activity): Active lymphocytes have more cytoplasm

Non-segmented nucleus, Typically deeply indented, Or lobed (bi-lobed, tri-lobed)

What is slightly larger than other WBCs, lacks distinctly stained granules and basophilically stained cytoplasm with clear vacuoles (lysosomes)

This Non-Granulocyte Circulates in blood stream for up to several days, also known as a macrophage.

BacteriaFungiProtozoansVirusesTransformed cellsDying cellsCell debris

Numerous short pseudopodial processes: amoeboid movement, cellular interaction (ex. cancer cells)

Cannot differentiate without IHC. Association with monocyte/macrophage (Mo/Ma)

Size varies for each sp: divided into small, large, & sometimes medium categories

Lymphocytes identical to mammals –difficult to distinguish from thrombocytes when small
