Q

Neutrophils/Eosinophils

A
  • WBC that assists with infections
17
Q

Adipocytes

A
  • Store fats
  • Found below skin, and around organs (heart, kidney)
18
Q

Macrophages

A
  • Develop from monocytes and destroy bacteria and cell debris
19
Q

Collagen Fibers

A
  • Very strong + resists tensile forces but not stiff, allowing flexibility
  • Found in bone, cartilage, tendons, and ligaments
20
Q

Elastic fibers

A
  • Found in skin, blood vessel walls, lung tissue
21
Q

Reticular Fibers

A
  • Provide support and strength
  • Consists of collagen
  • Found in tissues
22
Q

Areolar Connective Tissue

A

L: Subcutaneous layer deep to skin, papillar region of skin, lamina propria, and around blood vessels, nerves, and body organs
F: Strength, elasticity, and support

23
Q

Adipose Connective Tissue

A

L: Found where areolar connective tissue is located, subcutaneous layer deep to skin, around heart and kidneys, yellow bone marrow, padding around joints, behind eyeball
F: Reduces heat loss through skin, energy reserve, protects organs

24
Q

Reticular Connective Tissue

A

L: Stroma of liver, spleen, lymph nodes, red bone marrow
F: Forms stroma of organs, binds together smooth muscle tissue cells, filters/removes worn out blood cells

25
Q

Dense Regular Connective Tissue

A

L: Forms tendons, most ligaments, and aponeuroses
F: Provides strong attachment between various structures

26
Q

Dense Irregular Tissue

A

L: Fascia, reticular region of dermis of skin, fibrous pericardium of heart, periosteum of bone, perichondrium of cartilage, joint capsules, membrane capsules around various organs, heart valves
F: Provides tensile (pulling) strength in many directions

27
Q

Elastic Tissue

A

L: Lung tissue, walls of elastic arteries, trachea, bronchia tubes, and some ligaments between vertebrae
F: Allows stretching of various organs, can recoil to its original shape after being stretched

28
Q

Hyaline Cartilage

A

L: Ends of long bones, anterior ends of ribs, nose, part of larynx, trachea, bronchi, bronchial tubes, embryonic and fetal skeleton
F: Provides smooth surfaces for movement at joints, flexibility and support

29
Q

Fibrocartilage

A

L: Pubic symphysis, intervertebral discs, menisci, portions of tendons that insert into cartilage
F: Support and joining structures together

30
Q

Elastic Cartilage

A

L: Top of larynx, part of external ear, auditory tubes
F: Provides strength and elasticity, maintains shape of certain structures
