Frog and Human Anatomy Analysis
Frogs and humans have many similarities in their anatomy yet there
are many distinct differences. They share a similar body plan in their
skeletons and the functions, shape and placement of their organs. The
external body structure of a frog has mucus covered skin. Their skin
absorbs water and is important to their respiratory system. They also have
loose skin to help protect themselves from predators. Humans breathe
through their mouth and nose to get air to the lungs rather than absorbing
oxygen. Instead of absorbing water through their skin, humans must drink
their water in order to survive.
A large part of each skeleton have similar bones. They both have a
skill, vertebrae, and bones of the limb that are similar. A frog has a radioulna and a tibio-fibula which are singular bones fused together rather than
a human that has a radius, ulna, tibia and a fibula that are all separate
bones. Another big difference is the frog’s lack of a patella or a knee cap.
Although it is a similar shape, a frog has a super-scapula rather than a
scapula yet they are very similar shapes. They also have tarsals,
metatarsals, carpals and metacarpals that are the same for both frogs and
humans.
Both frogs and humans have a close circulatory system. Humans use
veins, arteries and the heart to pump blood throughout the body using one
loop. Frogs use red blood cells to carry the oxygen from its respiratory
systems throughout the body then it goes back to heart and then to the rest
of the body using two loops.
There is a significant difference between a frog and a human’s
respiratory systems. Frogs use their mouth, skin and lungs for its
respiratory system. Oxygen is exchanged from the lungs to the blood in the
capillaries.Their moist skin and mouth help to exchange the gases. For a
human, the main respiratory organ are the lungs. Red blood cells carry the
oxygen from the lungs to different parts of the body then take the carbon
dioxide and carry it to the lungs.
Frogs and humans have the same basic internal organs. Both have a
stomach, urinary bladder and a small and large intestines, heart, liver and
lungs. Along with a gallbladder, pancreas and spleen. They also have the
same reproductive organs yet they reproduce differently. Frogs lay eggs
into water as their children develop externally while humans develop
internally.
