Difference between Human and Frog
Transcript of Difference between Human and Frog
Cells of the stomach secrete gastric acid to break down food particles.
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.
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.
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.
Human brain tissue is always changing as the neurons are constantly moving.
The average human brain has about 100 billion neurons which serve to support and protect the neurons. Each neuron may be connected to up to 10,000 other neurons, passing signals to each other via as many as 1,000 trillion synaptic connections, equivalent by some estimates to a computer with a 1 trillion bit per second processor. Estimates of the human brain’s memory capacity vary wildly from 1 to 1,000 terabytes
Human stomach tissue absorbs nutrients from the food particles and helps them get into our bloodstream.
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.
Skin(integumentary system) forms the body’s outer covering and forms a barrier to protect the body from chemicals, disease, UV light, and physical damage. Hair and nails extend from the skin to reinforce the skin and protect it from environment
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.
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.
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.
Stomach cells produce gastric acid to break down and digest food.
Difference between Human and Frog
is the most superficial layer of the skin that covers almost the entire body surface.
is the deep layer of the skin found under the epidermis. The dermis is mostly made of dense irregular connective tissue along with nervous tissue, blood, and blood vessels.
contains many finger-like extensions called dermal papillae that protrude superficially towards the epidermis. The
increase the surface area of the dermis and contain many nerves and blood vessels that are projected toward the surface of the skin.
Deep to the dermis is a layer of loose connective tissues known as the hypodermis, subcutis, or subcutaneous tissue. The hypodermis serves as the flexible connection between the skin and the underlying muscles and bones as well as a fat storage area.
Epidermis of skin consist of inner stratum Malpighi (Stratum germinativum or stratum cylindricum) and outer stratum corneum.
Stratum Malpighi rests on the basement membrane. It is made of a single layer of columnar cells.
The cells of Stratum Malpighi undergo mitosis and form layer of cells towards outer side.
Dermis of skin consists of two layers, outer spongy layer called stratum spongiosum and inner compact layer or stratum compactum.
Stratum spongiosum contains cutaneous glands and pigments cells or chromatophores.
Two types of cutaneous glands present on the skin of frog are mucous glands and poison gland.
Mucous glands secretes mucous that makes the frog’s skin slippaery and moist.
The skin of frog is thin, moist and vascular. It performs cutaneous respiration.
A hibernating frog respires exclusively through skin.
Poison glands secrete a milky white poison ( well developed in toads as parotoid glands).
Mucous and poison glands are simple alveolar (acinar) glands.
Amphibians can change the intensity of skin color by contraction and relaxation of pigments cells.
The pigments granules may be aggregated or dispersed. This ability is called metachrosis.
Metachrosis helps to approach their preys unnoticed and also provides a protective device against their enemies.
Frog’s skin is not concerned with thermoregulation.
Skin plays a very important role in osmoregulation by osmotic inflow of water.
Human has three layers of skin while frog has only two layers of skin.There is no synthesis of vitamin D in the skin of frog. A frog's skin is protective, has a respiratory function, can absorb water and helps control body temperature.
Humans have A separate urinary syatem and separate genetal system. Frogs on the other had have a system called urinogenital system where single system functions for both urinary and genital purposesfor.
The frog, urine exits through the cloaca whereas humans, their urine exits through the urethra.
are a pair of bean-shaped organs found along the posterior wall of the abdominal cavity. The left kidney is located slightly higher than the right kidney because the right side of the
is much larger than the left side. The kidneys, unlike the other organs of the abdominal cavity, are located posterior to the peritoneum and touch the muscles of the back. The kidneys are surrounded by a layer of adipose that holds them in place and protects them from physical damage. The kidneys filter metabolic wastes, excess ions, and chemicals from the blood to form urine.The
are a pair of tubes that carry urine from the kidneys to the urinary bladder. The ureters are about 10 to 12 inches long and run on the left and right sides of the body parallel to the vertebral column.The
is a sac-like hollow organ used for the storage of urine. And located along the body’s midline at the inferior end of the pelvis. Urine entering the urinary bladder from the ureters slowly fills the hollow space of the bladder and stretches its elastic walls. The walls of the bladder allow it to stretch to hold anywhere from 600 to 800 milliliters of urine. The
is the tube through which urine passes from the bladder to the exterior of the body.
