How do the cells of a frog maintain homeostasis?
A frog maintains homeostasis using its skin. When the chytrid fungus infects the frog’s skin, it mucks up its ability to drink, exchange ions and do other functions properly.
How do frogs absorb water?
Frogs do not drink like we do; they absorb water directly through their skin in an area known as the ‘drinking patch’ located on their belly and the underside of their thighs.
How do frogs use diffusion to maintain water balance?
In fresh water, frogs have a body salt content much higher than the surrounding water and therefore tend to absorb water by osmosis and lose salts by diffusion through the skin. However, they have a physiology that compensates for this and they survive.
How does diffusion help frogs?
The thin membranous skin is allows the respiratory gases to readily diffuse directly down their gradients between the blood vessels and the surroundings. When the frog is out of the water, mucus glands in the skin keep the frog moist, which helps absorb dissolved oxygen from the air.
Why is frog skin loose?
In a pinch, frogs and toads can rely on dew for moisture, or burrow underground into moist soil. About once a week, frogs shed their skin. The process begins with the frog doing a lot of twisting, bending, and stretching to loosen the old skin.
What is the function of the kidneys in a frog?
The kidneys of a frog, like many other animals, filter the blood and excretes excess water. The ureters then carry the urine from the kidneys to the urinary bladder.
What are the functions of a Frogs eyes?
The eyes help push the food down its throat. Eyes positioned atop the head give frogs a field of vision of almost 180 degrees. This peripheral vision helps them spot predators and prey. Humans and other mammals focus images by changing the shape of the lens.
What is the function of the kidney in a frog?
What function do the kidneys perform?
Their main job is to cleanse the blood of toxins and transform the waste into urine. Each kidney weighs about 160 grams and gets rid of between one and one-and-a-half litres of urine per day. The two kidneys together filter 200 litres of fluid every 24 hours. to the blood.
