Alveoli
In the kidneys, waste is removed from the blood through this
Capillaries
The skeletal muscles are made of these
Ligaments, Bones, Cartilage
The wavelike contraction of muscles in the organs of the digestive system as it helps food move through the system is called this
Peristalsis
The circulatory system transports these three things
oxygen, nutrients and waste
Gases exchange between the air in the alveoli and blood are located in this
Capillaries
Through the many steps of removal in the Excretory System, ammonia is in the blood and the liver converts the ammonia into urea. As the blood continues to travel to the kidneys, the kidneys filter urea and waste from the blood resulting in this
