Human vs. Frog Anatomy

Human Vs. Frog Anatomy

Human neurons fire action potentials at around 200 mph.

Human brain tissue is always changing as the neurons are constantly moving.

Frog neurons control simple functions, as frogs don't have reasoning or intelligence skills.

Frog neural tissue makes up and connects the different hemispheres of the brain.

The human brain is much more complex than the frog brain. As you can see, the human brain has a round shape with lots of hemispheres and sections for controlling different functions. The frog brain is less complex and more spread out than the compact human brain.

Human lung cells take in oxygen and help transport it to the circulatory system, then carry carbon dioxide back out.

Human lung tissue is flexible and porous so it can help inhale, exhale, and carry oxygen and carbon dioxide easily.

The frog's lung cells filter oxygen and carry it to the heart, then send carbon dioxide back out.

The frog's lung tissue is only one layer of cells thick so that gases (oxygen and carbon dioxide) can pass through it quickly.

The lungs of both bodies function rather similarly. The frog's lungs are located on the posterior where the human's are locate more on the anterior, but they provide the same function of transferring oxygen to carbon dioxide.

Stomach cells produce gastric acid to break down and digest food.

Human stomach tissue absorbs nutrients from the food particles and helps them get into our bloodstream.

Cells of the stomach secrete gastric acid to break down food particles.

This is a frog's stomach tissue. The tendril-like parts help to absorb water. The skin and tissue of the frog are so porous that the frog rarely has to drink water, its body just soaks up water from the ground when it touches it.

The stomachs and digestive system of the frog and the human are also relatively the same. They are located on opposite sides of the body: frog on the left and human on the right, but they have the same job of breaking down food. The frog's digestive system probably has to work a little harder than the human's, as the frog doesn't chew its food first.

Connections:

• Brain (nervous system) controls all the other systems of the bodies-including respiratory and digestive
• The lungs (respiratory system) take in oxygen that all the parts of the body need. Through the circulatory system, the oxygen from the respiratory system gets carried to the brain and digestive organs.
• The digestive system breaks down all the nutrients the body needs and gets rid of the waste that the body doesn't need. The nutrients get dispersed throughout the body where they are needed via the circulatory system, and end up in places like the brain and lungs.
