Quiz Wed Flashcards
This is the taking in of food from
the environment into the mouth.
Procurement of food
This is the chewing of food.
Mastication
This is the swallowing of food.
Ingestion
This is the process of breaking down complex food substances by a series of chemical changes.
Digestion
This is the transfer of digested food from the gut of the small intestine to the blood vessel.
Absorption
This is the movement or transport of food substances in the blood vessels to the cell.
Curculation
This is the integration of food substances in the cell
Assimilation
This is the actual use of food for growth, structural maintenance, and the production of the various forms of energy
Utilization
the process of breaking down complex food substances by a series of chemical changes into absorbable form.

Digestive system of the frog is
Complete digestive system
This is also known as the mouth cavity.
Buccal cavity
It is the structure that
receives the food from the external environment
Buccal cavity
These are the many miniature teeth on the upper jaw. These teeth are not for chewing.
Maxillary teeth
These are teeth that are arranged on the winged shaped vomer bone between the internal nares. This is used to hold the food in place.
Vomerine teeth
These are two openings that are connected to the external nares for the entrance of air.
Internal nares
The frog has no palate. True or false
True
These are two openings found at the corner of the mouth which are connected to the cavity of the middle ear under the eardrum
Eustachian tubes
This is a muscular structure which is free and notched at the posterior end and is attached anteriorly. This is also sticky to capture live insects for food.
Tongue
This is found embedded below the tongue.
Hyoid cartilage
This is a cavity or space behind the tongue.
Pharynx
This is a lengthwise slit in the ventral wall of the pharynx Which serves as the entrance of air. This is bounded on each side by the epiglottis.
Glottis
What bounds the glottis?
Epiglottis
This is a muscular structure which is free and notched at the posterior end and is attached anteriorly.
Tongue
This is located posterior to the pharynx which serves as the entrance food.
Esophagus
There are structures that produce croaking sounds; they are only found in male frogs
Vocal sacs
This is where the coelom (body cavity) and organs are found
Peritoneum
The peritoneum is folded
Dorsally downward
found around the heart also arise from
the peritoneum
The pericardium and pericardial sac
It is an almost imperceptible structure that connects the buccal cavity to the stomach.
Esophagus
It is a large pouch of J-shaped structure which is the temporary storage of food. This is located along the left side, dorsal to the liver.
Stomach
This is a yellowish or grayish structure, slender and irregularly coiled, and generally divided into two parts
for final digestion of food.
Small intestine
The small intestine is generally divided into two parts:
the duodenum and ileum
Also called the colon, it is a structure, diameter of which is a little wider than that of the small intestine where undigested food passes through.
Large intestine
The external structure that releases the waste and other materials in the ervironment.
Cloaca/anus
digestive system has two digestive glands that facilitate digestion of
food. These are
Liver and pancreas
It is a large, firm, reddish brown structure with three lobes. This
secretes bile to emulsify fats.
Liver
Located Between the lobes of the liver, a greenish structure that is used as temporary storage of bile which is
connected to the small intestine through a bile duct.
Gall bladder
It is an irregular flattish glandular tissue lying adjacent to the
Duodenum. It secretes yellowish pancreatic juice.
Pancreas
Through this system, organism is able to obtain oxygen and get rid of carbon dioxide.
Respiratory system
is used to release energy from
food during which process carbon dioxide is formed.
Oxygen
We need to eliminate ____ from the body to avoid poisoning
Surplus of carbon dioxide
inhalation or taking in of oxygen
Inspiration
the exhalation or giving off of carbon dioxide.
Expiration
two phases involved for exchange of
gases to take place between the organism and its environment:
External and internal respiration
Exchange of gases between the
atmosphere and the blood. This involves the lungs.
External respiration
Gas exchange between the blood and
the body tissues. It occurs in every living cell.
Internal respiration
The main organs for respiration in terrestrial vertebrates are the
Lungs or gills in aquatic form
While the adult frog is submerged in water, it utilizes what?
cutaneous respiration or skin respiration
In the larval form,____ are used; and when already an adult,
the frog uses the_____.
Gills
Lungs
These serve as the entrance to the nasal cavities.
External nares
These are paired openings inside the mouth lateral to the vomerine teeth
Internal nares
It is a narrow way between the external nares and internal nares
Olfactory canal
This is the part where gaseous
exchange takes place through the lining of the mucous glands
Mouth or buccal cavity
It is a slit in the laryngeal prominence on the floor of the pharynx.
Glottis
The sides of the glottis are bounded by a pair of
arytenoid cartilage
arytenoid cartilage is surrounded by
Cricoid cartilage
the outer walls of the lungs are occupied by a membrane, the____, which is an extension of the________
Pleura
parietal peritoneum.
concerned with the removal of the
nitrogenous wastes of metabolism.
Excretory or urinary system
The main excretory organs of
vertebrates are the
kidneys with their ducts.
To expose the kidney, turn the frog to one side and slit carefully reveal the
_____________
parietal peritoneum.
Parts of the excretory system
Kidneys
Adrenal glands
Ureters
Urinary bladder
Cloaca
These are a pair of flattened, elongated, dark-red bodies
lying in the subvertebral lymph sinus behind the parietal pertoneum.
Kidneys
These are yellowish endocrine glands on the ventral surface of the kidney.
Adrenal glands
It is a pair of white, slender tubes on the postero-lateral of each kidney with a blood vessel, the renal portal vein
Ureters or mesonephric duct.
It is a bibbed sac on the ventral surface of the cloaca for the temporary storage of urine.
Urinary bladder
It is the posterior part of the digestive tract receiving the urinary and genital ducts on the ventral surface.
