Two structures that belong to the respiratory system are the trachea (windpipe) and the bronchial tubes. The trachea carries air from the throat to the lungs, while the bronchial tubes divide in the lungs to deliver air to each lung's air sacs.
The pharynx belongs to both the respiratory system and the digestive system. It serves as a passageway for air to travel from the mouth and nose to the trachea and for food to travel from the mouth to the esophagus.
The mammary glands belong to the reproductive system and the integumentary system. They are specialized glands within the breasts that produce milk for nourishing offspring, which is essential for reproduction. The integumentary system includes the skin and its associated structures, such as hair and nails, which also encompass the mammary glands.
Joints belong to the skeletal system in the human body, where they connect bones together and allow for movement. Some examples of joints include ball-and-socket joints (like the hip joint) and hinge joints (like the knee joint).

The main structures of the central nervous system are the brain and the spinal cord.
The Testes and Ovaries belong primarily to the reprodutive system. Each one produces gender specific gametes that are combined to create genetically unique offspring. These two organs also belong to the hormonal, or endocrine, system. They are involved in the production of chemicals that help control and guide things like growth and fertility.
the kidney belongs to the osmo-regulation and the excreatory system.
spleen and tonsils
