The respiratory system cosist of two part………..
Conducting part and respiratory part
Conducting part consist of……
Nostril, nasal cavity , nasopharynx , larynx , trachea , bronchi and bronchiole(primary and secondary)
Respiratory part includes…..
Tertiatry bronchiole , respiratory bronchiole , alveolar ducts and alveoli
Alveoli back to
Secondary bronchiole back to….
Conducting part
What's the main functions of respiratory system?
1_respiration
2_ phonation
3_olfaction
4_heat regulation
5_lungs
Respiration include….
A/taking enough amount of oxygen that body required
B/correction and conducting of inspired air
Explain included of correction and conducting of inspired air .
1_warming or cooling the inspired air by aid of the venous plexuses
2_purification of inspired air by the aid of cilia and goblet cell secertion
3_noting the presence of inspired harmful substances and making a reflex that close the air passage of larynx
The air warmed by …….in ……..part
by venous plexuses in conducting part
Purification of inspire air by…….
Cilia and goblet cell secretion
How phonation occur?
Movement of air across the vocal folds causing their vibration
How characteristic sound produce?
By modified by the tongue , the oral cavity, the teeth and the lips
Olfactory cells in the ….
Caudal part of nasal cavity
Olfactory cells function……..
Determination of toxicity of inspired gases and type of odder smelled
……….. connect the olfactory nerve via the ethmoidal bone
Olfactory cells
Respiration help in regulation of body temperature via….
Evaporation
……..the largest part of small intestine
Jejunum
Why it called jejunum?
Because when we open it it's almost empty or has little liquid ingesta.
Jejunum start from….
Doudeno jejunal flexure
The mesentery of the jejunum called….
Mesojejunum
Why the mesojejunum less motility in ruminants?
Because jejunum tightly coiled along the edge of mesentery around coiled ascending colon
…….lie between stomach and pelvic inlet
Describe jejunum of horse.
Is very long lies at the left dorsal part of the abdominal cavity mingled with the large coils of descending colon
What's this?
ileum suspended by ……
Mesoileum
ileum attached to the cecum by…..
Ileucecal fold
Opening of ileum surrounded by an elevation called
Ileal papilla
Ileal papilla lies at….
Medial face of the cecal base
Describe ileim in the horse.
The opening of the ileum surrounded by an elevation called the ileal papilla which contain venous plexus due to partially telescope of ileum into cecum , this opening lies at the medial face of cecal base . Ileal orifice of horse lie about 5 cm . Away of cecocolic opening which lie caudolaterally.
Cecocolic opening lie…….
Caudolaterally
Large intestine consist…..
Cecum , colon , rectum
Cecum is ……
Initial blind sac of large intestine
Cecum of rabbit have ….
Appendix
Cecum of cat is ……..
Very short
Cecum of dog …….
Longer with screw like shape
Cecum in ruminants……
Larger with cylindrica (tubular) shape
Cecum in horse…….
Is very large with comma like shape
