Function of lymph node

Filtration -removal of microorganism and cell debris enter lymph before lymph returns to blood circulation



Site of lymphocyte activation and proliferation - after encounter with antigen in lymphatic sinus

Characteristic that helped Id - cortex has follicles tonsils

Tonsil

Function removes pathogens present in food and air from entering pharynx



Exposure to pathogens generates memory effector lymphocytes


Characteristic helping id- tonsular crypt an incomplete capsule

Characteristic helping id- tonsular crypt an incomplete capsule

Spleen

Red pulp function to remove damaged red blood cells and platelets


White pulp function immune function of spleen monitors pathogens and site of lymphocyte proliferation

Identifying characteristic.


Lymphoid follicles not limited to superficial cortex

Small intestine

Peyers patch - lymphoid follicles in mucosa


Monitor intestinal bacteria and prevent growth of pathogenic bacteria in intestines


Finger like structures called villi which increase surface area


Thymus

Function maturation site of t lymphocytes


Identifying characteristic


Big circle is thymic corpuscles


Surrounded by little circles epithelium


Small dark T cell


Small light are epithelial cells

Identifying characteristic
Big circle is thymic corpuscles
Surrounded by little circles epithelium

Lung cells

Alveoli function site of gas exchange between blood and air


Alveolar duct function to connect alveoli to larger airway


Alveolar pore function to connect alveoli to each other and to alveolar duct

Broncus airway

Function branching air way that leads from outside to alveoli

Identifying characteristic


Oval shape with wavy walls


Branches of bronchus with many levels of branching


More branching = less cartilage

Cat trachea

Id incomplete cartilage forming its walls


Functions as an airway

Cat epiglottis

Function prevents food from entering trachea

Cat esophagus

Function carries food into stomach during swallowing

Cat Larynx

Routes air into trachea and produces sounds during speech

Cat laryngopharynx

Routes food into esophagus during swallowing

Cat glottis

Opening between vocal cords flow of air produces vibration of vocal cords producing sounds

Primary bronchus

Functions as air passage

Thyroid and cricoid cartilage

Function : helps form framework of larynx
