Frog Morphology and Anatomy
-
What is the name of the blood vessel that carries deoxygenated blood from the body to the heart in a frog?
Vena cava brings deoxygenated blood from the frog's body into the sinus venosus.
Deoxygenated blood from body organs is collected by major veins called vena cava (two precavals and one postcaval), opening into the sinus venosus attached to the right atrium of the frog's heart.
Frog Morphology
-
Which of the following statement is correct about location of the male frog copulatory pad?
Copulatory pad is present on the first digit of the forelimb in male frogs.
Male frogs are distinguished from females by having vocal sacs and a nuptial/copulatory pad situated on the ventral side of the first digit of the forelimbs to aid in amplexus.
Frog Circulatory System
-
In frog, the Renal portal system is a special venous connection that acts to link:
Renal portal system connects the lower parts of the body/hind limbs to the kidneys.
In amphibians (frogs), blood from the hind limbs and lower abdominal regions is collected and routed to the kidneys via the renal portal vein, constituting the renal portal system.
Frog Respiratory System
-
Frogs respire in water by skin and buccal cavity and on land by skin, buccal cavity and lungs.
Choose the correct answer from the following:In water, frogs respire solely by skin (cutaneous); on land, they respire via skin, buccal cavity, and lungs.
In aquatic conditions, skin serves as the aquatic respiratory organ (cutaneous respiration only). On land, respiration is carried out by skin, buccopharyngeal cavity, and lungs (pulmonary respiration). Hence the statement is false for water but true for land.
