Organ Systems In Animal Flashcards
Which seperate the wind pipe and food tube
Palate
In human two set of teeth
Diphyodont
First appearing set of 20 teeth called
Temporary or milk teeth
Each tooth has a root fitted in the gum
Theocodont
Permanent teeth are 4 type Heterodont
Incisors. 8. cutting and biting
Canine. 4 tearing and piercing
Premolars 8. crusing and grinding
Molars 12. crushing grinding
and mastications
Salivary glands
Parotid gland- largest salivary gland in front of ears
Sublingual gland - smallest gland lie beneath the tongue
Sub mandibular or sub maxillary gland - angle of lower jaws
Salivary gland secrete a viscos fluid called salivary approximately
1.5 litre
_______in saliva which convert starch (polysaccharides) into maltose (disaccharide)
Ptyalin
Saliva also contain an antibacterial enzyme called
Lyzosyme
_______ closes and prevent the food from entering into trachea (wind pipe)
Epiglottis
Oesophagus or the food pipe is a muscular membranous canal about ______ in length
22 cm
The gastric juice is colourless highly acidic containing muscas hydrochloric acid
Enzyme Rennin (in infants ) and pepsin
Pepsin
Protein
The chyme moves to the intestine slowly through the
Pylorus
Cause curdling of milk protein caesin and increase digestion of protein
Rennin
Convert angiotensinogen to angiotensin and regulate the absorption of water and na+ from glomerular filtrate
Renin in kidney
Small intestine is the longest part of alimentary canal
5-7 m
Duodenum
Jejunum
Ileum
Duodenum is C shaped and receives the
Bile duct(liver)
Pancreatic duct (pancreas)
Shortest region of small intestine
Jejunum
The secretion of the small intestine is intestinal juice which contain the enzyme like
Sucrose
Maltase
Lactase
Lipase
The longest part of small intestine
Ileum
Ileum contains minute finger like projection called
Villi
Approximately 4 million
The father of gastric physiology
William Beaumont 1785-1853
He concluded that the stomach’s strong hydrochloric acid played a key role in digestion
