For respiration, Eagles have nares which are nostrils on the beak for them to breath. They breath in oxygen and it goes into the air sacs in the lung. Then, releases out the lungs and out the nare as carbon dioxide.

Eagles have a closed circulatory system. Their circulatory system does many things ours does. Transporting oxygen to blood, removing waste, and regulate body temperature. They have a four chambered heart with arteries to transport blood away from heart.
Digestion
Bald Eagles have an effective digestive system that digests and passes food quickly. Their stomachs have 2 chambers where the food is ground up y the gizzard and then digestive enzymes break it down even more. Finally, passes through intestines.

Food Getting
Bald Eagles catch prey by swooping down and grabbing the prey with their curved and sharp claws. They will swoop down and steal from other birds or animals if they find the chance. They sometimes even eat decaying flesh of dead animals

Support
Bald eagles have an endoskeleton with hollow bones. Like all birds, they have hollow bones to decrease their total body weight to be able to take off and fly. Bald eagles also have spicules on the bottom of their feet to e able to hold prey while flying

Movement
Eagles have long and wide wings. This design helps them slide in the air better and longer. These wings also provide more lift when carrying prey in the air.

Excretion
Eagles secrete waste from one hole like most birds. Urine and feces exits one hole called the cloaca. Eagles maintain water balance by using salt glands. This keeps salt levels in check.

Temperature regulation
Eagles use counter-current heat exchange to maintain body temperature. Warm blood passes cool blood to balance out.
