How is the frog skeleton similar to humans?
The frog has one “forearm” bone, the radio-ulna. Humans have two forearm bones, the radius and the ulna. Both frog and human have one “upper arm” bone, the humerus. The hind legs of the frog are highly specialized for leaping.
How is a frog a living thing?
Frogs belong to a group of animals called amphibians. Amphibian means two-lives. Frogs begin their lives in the water as eggs and then tadpoles and when they are fully developed they live on land.
Why do you think frog anatomy is so similar to human anatomy?
Both creatures possess a circulatory system, which operates as the heart pumps blood throughout the body. However, frogs have a three-chambered heart, with two atria and one ventricle compared to the human’s two atria and two ventricles. Additionally, frogs and humans have similar digestive and respiratory systems.
How are the human and frog urinary systems similar?
1)They both have a pair of kidneys for removing the wastes and extra substances from their bodies. 2)They both have a pair of ureters for the passage of the urine. 3) They both have one urinary bladder for the storage of urine. 4)The path of urea and urine is the same in both organisms.
How does the frog muscular system compared to the human muscular system?
Muscles in both frogs and humans adhere to a skeleton. For example, humans have 24 vertebrae that allow for back arching movements, while frogs have only nine. A frog’s combined tibiofibula, or large shin bone, makes jumping much easier compared to the separate shin bones in humans.
What habitats do frogs live in?
Frogs thrive in a large number of environments from tropical forests to frozen tundras to deserts. Their skin requires freshwater, so most frogs live in aquatic and swampy habitats. There are a number of exceptions, including the waxy tree frog, which can be found in the arid region of Gran Chaco of South America.
What is the main difference between human and frog reproductive systems?
Frogs undergo external fertilization but human undergo internal fertilization. Frogs release a large number of ova (spawn) it doesn’t happen in humans.
What is the function of the excretory system in a frog?
Mainly, this system excretes urea which is carried into the kidney by the blood and eventually is distilled and excreted out. The renal structures of this system hence remove urea from the body of the frog.
