The surface area of the lungs is significantly larger than that of the skin. The total surface area of the lungs is estimated to be around 70 square meters, primarily due to the extensive network of alveoli for gas exchange. In contrast, the average surface area of human skin is about 1.5 to 2 square meters. This means the lungs have a surface area many times greater than that of the skin.

Why have lungs replaced skin for gaseous exchange?
Lungs have evolved to replace skin for gas exchange because they are more efficient at extracting oxygen from the air and eliminating carbon dioxide from the body. Lungs have a larger surface area, thanks to the branching structure of the respiratory system, allowing for more effective exchange of gases between air and blood. This specialized design enables a higher rate of gas exchange compared to skin, making it better suited for efficient respiration in terrestrial animals.
Which substance is lost from the body by the kidneys lungs and skin?
Water is the substance lost from the body through the kidneys, lungs, and skin. The kidneys filter it from the blood to produce urine, the lungs release it through exhalation, and the skin eliminates it through sweat.
Is the butt thick skin?
Yes, the skin on the buttocks is generally thicker compared to other parts of the body, such as the cheeks or eyelids. This is to provide cushioning and protection for the muscles and bones in that area.

Why have lungs replace with skin for gaseous exchange in higher organisms?
Lungs have evolved in higher organisms because they provide a more efficient means of gas exchange compared to skin. Lungs offer a greater surface area and a more controlled environment for oxygen and carbon dioxide exchange, which is essential for meeting the metabolic demands of larger and more active animals. Skin-based respiration is limited by factors such as surface area and moisture retention, making it less effective for sustaining the higher oxygen needs of complex organisms. Additionally, lungs allow for the regulation of gas exchange and protection against environmental factors.
Is tuberculosis adisease of skin liver or lungs?
Lungs
Is MRSA in the bloodstream worse than on the skin?
Mrsa on the skin is mild compared to the bloodsteram due to in the bloodstream it can affect more parts of the body like the lungs, urinanry tract and can infect open wounds.

Name one organ in your body which has a large surface area?
The skin is an organ in the body that has a large surface area as it covers the entire external surface of the body.
How many lungs do amphibians have?
they use their gills, skin, and later in life they use their lungs :)
What is pulmocutaneous artery of frog?
An artery which goes to the lungs, and the skin, making it possible for the frog to breathe through the skin, and not the lungs.
What is a flap of skin that shuts off the passage to the lungs?
The flap of skin that shuts off the passage to the lungs is called the epiglottis.

Does oxygen and carbon dioxide exchange in reptiles in the lungs and skin or just the lungs?
Just through the lungs.
How does the three-chambered heart equip amphibians for life on land?
The frog's three-chambered heart more efficiently delivers oxygen to body cells as compared to the fish's two chambered heart. As compared to a four-chambered heart, the frog's three-chambered heart allows blood to bypass the lungs when the lungs are not functioning in gas exchange. In the three-chambered heart of amphibians, one chamber receives blood from the lungs and another receives blood from THE REST OF THE BODY, INCLUDING THE SKIN. Blood from both chambers then moves to the third chamber, which pumps blood back to the lungs, skin, and rest of the body. This results in some mixing, BUT EXPERIMENTS USING DYES HAVE SHOWN THAT BLOOD PUMPED TO THE LUNGS AND SKIN COMES PRIMARILY FROM THE SKIN AND THE REST OF THE BODY AND BLOOD PUMPED TO THE HEAD COMES PRIMARILY FROM THE LUNGS. BLOOD PUMPED TO THE REST OF THE BODY IS A MIXTURE OF OXYGEN-POOR BLOOD FROM THE REST OF THE BODY AND BLOOD FROM THE SKIN AND LUNGS, WHICH CARRIES OXYGEN. IHOWEVER, in amphibians, the skin is much more important than the lungs as an organ for gas exchange, especially when the frog is under water. THE LACK OF TOTAL SEPARATION OF THE BLOOD IN THE HEART ALLOWS BLOOD TO DETOUR AROUND THE LUNGS WHEN THE FROG IS UNDER WATER. AS COMPARED TO A TWO-CHAMBER HEART, DOUBLE CIRCULATION THROUGH THE HEART RESULTS IN A MUCH HIGHER BLOOD PRESSURE IN THE ARTERIES GOING TO THE BODY.
