locomotion system of frogs

Respiratory system - It consists of a pair of lungs, a pair of bronchi and a trachea. The lungs contain numerous microscopic functional units called alveoli. These structures are involved in pulmonary respiration. In addition, there is buccal respiration, through the buccal cavity and cut..

Skeletal system - Frog, being a typical vertebrate, shows the presence of a skeletal system that forms the internal supporting framework for the body. It can be distinguished into an axial skeleton and an appendicular skeleton. Axial skeleton consists of skull, vertebr..

The body of the frog can be distinguished into head and trunk. The head is triangular in shape and it contains a mouth, a pair of nostrils and retractible eyes. The trunk merges with the head and lacks a neck. The trunk bears a pair of forelimbs and a pair of hind limbs. The ge..

It consists of heart, blood vessels and blood. Heart is three chambered with two auricles and one ventricle. There is a mixing of the oxygenated and deoxygenated blood in the ventricle. Blood vessels are represented by arteries, veins and capillaries. Arteries, which carry blood away from the heart..

Movements and locomotion takes place as a result of co-operation between the muscle and skeletal system, hence the study of both is necessar..

Animals are different from plants because of their ability of locomotion. This ability probably developed as they have to search for food, unlike the plants that are autotrophic. Since they move from place to place, the animals have to continuously encounter changes in their environment. ..

One of the indirect evidences for evolution comes from the study of homologous organs in organisms that exist today. Homologous organs are those, which have the same basic structure, but different functions. For example, an examination of the forelimb skeleton in different groups of land vertebrat..

>Cilia can perform a variety of functions: 1. In certain molluscs, cilia help to pass water currents over the gills 2. In echinoderms cilia helps to drive water through the water vascular system, (locomotion) 3. Cilia of the cells lining the respiratory tract of humans help to d..
