  • For bacterial infection
  • Predominant sa circulation
A

Neutrophil

26
Q
  • Its nucleus is typically closer to the size of the RBCs.
  • One big oval shape.
  • Its main function is for cellular defense and production of antibodies.
  • Walang granules
  • Almost the same to macrophages
  • Increased lymphocyte:
    o intracellular infections/viral infections

A

Lymphocyte

27
Q

orchestrator or mastermind of immune responses. They will produce different substances.

A

T helper:

28
Q

produces toxic substances to kill intracellular pathogens. Bind to the cell to kill it. Mainly this is defense for intracellular pathogens.

A

T cytotoxic

29
Q

It can mature into plasma cells
Plasma cells will produce different antibodies to the surface.
Then these antibodies will detach and will try to find yung nagca-cause ng disease.

A

B cells

30
Q
  • Kidney bean-shaped, irregular cytoplasm
  • Clean up crew.
  • Macrophage cleans bacteria, debris, and affected cells. → for elimination
    o Sa circulation, onti lang _____ then sa tissues ay macrophages.
A

Monocyte

31
Q

Bi-lobe nucleus.
* Increased during parasitic infection

A

Eosinophil

32
Q
  • Typically 0-1 lang sa differential cell count.
  • Pag tumaas, may sakit na.
  • Release heparin and histamine.
  • The rarest.
A

Basophil

33
Q

natural anti-coagulant of the body

A

Heparin

34
Q

Liquid form sa body

A

Anti-coagulant

35
Q

mediation of immune response

A

Histamine

36
Q

Types of Fibers

A
  • Collagen
  • Reticular
  • Elastic
37
Q

Collagen fibers made up of type I collagen

A

Fibrillar collagen

38
Q

o Laminae
o The one connecting basal lamina and epithelium

A

Network or sheet-forming collagens

39
Q

Anchors tissues to basement membrane

A

Linking/anchoring collagens

40
Q

pre-cursor of collagen

A

Procollagen alpha chains

41
Q

o Local swelling caused by abnormally large amounts of collagen that form in scars of the skin
o Due to certain hereditary defect, sumosobra yung collagen during tissue repair.
o Mostly black people/African people yung nagkakaroon ng keloids

A

Keloids

42
Q

Found in delicate connective tissue of many organs
* Argyrophillic – needs silver stain (to be able to see)
* PAS-positive (Periodic Acid Schiff)
* Delicate reticular networks serve as the supportive stroma for the parenchymal secretory cells and rich microvasculature
o Example: liver and endocrine glands
* Mainly made up of type lll collagen (found in delicate connective tissues)

A

Reticular fibers

43
Q

Structure or supportive part of the matrix. They hold the structure or the tissue together

A

Stroma

44
Q

Constituents of the matrix

A

Stroma,Parenchyma

45
Q

The functional part. Usually consists of different cells with certain functions (laman)

A

Parenchyma

46
Q
  • Have rubberlike properties that allow tissue containing these fibers to be stretched or distended and return to their original shape
  • Not strongly acidophilic
  • Can be seen in the lungs, capsules, pericardium, urothelium (composed of transitional epithelial tissues)
A

Elastic fibers

47
Q

a disease characterized by a lack of resistance in tissues rich in elastic fibers

A

Marfan Syndrome

48
Q

Types of connective tissues

A

Loose connective,Dense regular,Dense irregular,Reticular,Mucoid

49
Q

Forms a layer beneath the epithelial lining of many organs and filling the spaces between fibers of muscle and nerve
* Typically contains cells, fibers, and ground substance in roughly equal parts
* Flexible and not very resistant to stress

Additional:
* Mas maluwag, mas stretchy as compared to dense connective tissue
* Decreased collagen, increased yung fibrolasts kasi siya yung mas malapit sa balat.
* Fibrolasts produces substances for tissue repair.

A

Loose connective tissue

50
Q
  • Similar components as loose connective tissue but with fewer cells
  • Type I collagen predominant
  • Dense irregular – randomly interwoven collagen granules w/ no definite orientation
  • Skin
  • Dense regular – aligned in parallel for great resistance to prolonged or repeated stresses from the same direction
  • Tendons and ligaments
    Additional:
  • Fewer cells, increased collagen
  • Mas strong structurally as compared to loose.
A

Dense Connective tissues

51
Q
  • Abundance of type III collagen fibers
  • Delicate network that supports various types of cells
  • Provides a framework with specialized microenvironments for cells in hemopoietic tissue and some lymphoid organs
  • Lymphoid organs example: bones/bone marrow
A

Reticular tissue

52
Q

– modified fibroblasts na makikita sa reticular tissue

A

Reticular cells

53
Q
  • Principal component of the fetal umbilical cord
  • With abundant ground substance composed chiefly of hyaluronan
  • Sparse collagen fibers and scattered fibroblasts
    Additional:
  • Fetal umbilical cord (whartons jelly)
  • Hyaluronan: protein
  • Developing pa kasi connected sa fetus
  • Maraming fibroblasts
A
