Liver, if the skin is counted as the largest.
The liver is the second heaviest organ in the human body, after the skin. It plays a vital role in metabolism, detoxification, and nutrient storage.
The skin is the largest organ in the body. It serves as a protective barrier between your internal organs and the outside world, helps regulate body temperature, and is involved in sensation and immunity.
I would say that they are all important and all hold the same necessity. for example of the kindeys begin to fail then a toxic build up would occur, this would effect the cardiovascular system (CVS) which would transport the waste all over the body. likewise if something happened to the liver food wouldn't break down properly, jaundice would occur, the digested food wouldn't break down properly and proteins would be deficient along with minerals and nutrients. each organ is linked to the others via the CVS which produce hormones to create a balance and homeostasis. the only organ which i would assume is not neccasary is maybe the 2nd kidney as long as the first one is ok lol
the Atlantic Ocean, the 2nd largest ocean on Earth
The femur (thigh bone), tibia (shin bone), and humerus (upper arm bone) are three of the strongest bones in the human body. These bones support the body's weight and play critical roles in movement and protection of vital organs.
The Atlantic Ocean is the second largest ocean in the world at 76,762,000 sq km. Its deepest point is the Puerto Rico Trench (Milwaukee Deep) at 8,648 metres.
