Three – sub phylum
Four – super class
Five – class
Genius and species, –
One – Animalia
Two – Chordata
Three – vertebrata
Four – tetra Poda
Five – Amphibia
Genus – Rana
Species – tigrina
During peak, summers and peak winters, frogs are usually not spotted. Make deep burrows and go to.
Aestivation and hibernation
Colour change is called
Camouflage
Protective colouration to hide from enemy is known as
Mimicry
Frog body is divisible into
Head and trunk
Neck and tail is absent
Colour of body
One – dorsally – olive green with dark irregular spots
Two – ventrally – pale yellow
Skin of frog
Moist
Smooth
Slippery – has a lot of mucus
Frog never drinks water, but absorbs through skin
To protect their eyes underwater, they have a covering over it called as
NICTITATING membrane
A pair of eye present within orbit of skull
Behind the eyes a membranous fold is present to receive the sound vibrations
Tympanum
Limbs
One – four limbs – – – one pair and ends in four digits
Two – hind limbs – – – ends in five digits and our web, more muscular
Sexual dimorphism is present in frogs
One – vocal sack are present in male flog, which is used to produce croaking sound during breeding season
Two – a copulatory pad is present on the first digit of four limbs
Where the copulatory pad is present in frog
First digit of fourlimb
Do frog have body cavity?
If yes, why?
Frog has body cavity required for placing all the organ systems
Why the frog has shorter intestine
Because they are carnivorous
Digestive glands in frog is present in
Liver and pancreas
Parts of alimentary canal of frog
Mouth – buckle cavity –pharynx – food pipe – stomach – in intestine – cloaca
Parts of intestine in frog
One – small intestine – DUODENUM and I LEUM
Two – large intestine – rectum
Secretion of liver and what its function
Lever bile juice
It EMULISIFICATION of fat
Where the bile juice secreted by liver is stored
Gallbladder
What is CHYME?
When food mixes with gastric juice in stomach is known as
What is secreted by pancreas? And what its function.
Pancreatic juice
It has enzymes to digest protein and carbohydrate
What kind of tongue is present in frog?
The tongue is bilobed and prehensile
Protein digesting enzymes released in stomach as known as
PEPSINOGEN
What carries the bile and pancreatic juice to small intestine?
Common bile duct
Where the water absorption is done in frog
Rectum
Digestion completes here in intestine, mainly involved in absorption of the end, product of digestion
ILEUM
CLOACA is a common chamber in which opening of three system is seen
ALIMENTARY plus reproductive plus excretory
Numerous number of Villa and microvilli helps in absorption of and product of digestion present in
ILEUM
Lungs of frog
One pair
Pinkish sack like
Located located in the upper part of trunk
What is the type of respiration in?
One – water
Two – during hibernation
Three – on land
One – cutaneous respiration
Two – cutaneous respiration
Three – cutaneous/buccal respiration/buccopharyngeal respiration/pulmonary respiration
What type of blood vascular system is present in frog?
Closed circulatory system
Blood vessel bounded by capillary
Heart in frog
Muscular located in upper body ventral
Covering of heart
Double layered pericardium
How many chambers are present in heart of frog?
Name them
Two atrium, one ventricle
Frog has two additional chambers called
One – SINUS VENOSUS
Two– CONUS/TRUNCUS ARTERIOSUS
Name the chamber
It is located on dorsal side of heart connected to right atrium
It is triangular in shape
Sinus venosus
Describe conus arteriosus
It is located on ventral side of heart, connected to ventricle
It is SAC like
One – Which takes away the blood from heart
Two – it takes the blood towards the heart
One – artery
Two – vein
The circulation of frog is called as
Mixed circulation or incomplete double circulation
Types of portal, circulation present in frog
Hepatic
Renal
What is portal circulation?
A special Venus connection between two organs, which starts from capillary and ends with capillary
