The cardiovascular and respiratory systems are two different systems in the body, though they are closely related. The cardiovascular system is made up of the heart, blood vessels, and blood. The respiratory system is made up of the trachea, bronchii, alveoli, and the lungs.
The organs that make up the respiratory system are the lungs ,trachea ,bronchial tubes,mouth,nose( anything you use to breath.)IDK i think this is right i studied it for a while til i dropped out. We got the nasal passage, oral cavity, pharynx, larynx, trachea, bronchi, lung, heart, and the ribs.
A fact about organs is that you need cells and tissue to make up organs. because cells make up tissue and tissue makes up organs and organs make up organ system and an organ system makes up organism which are how humans are made up by.
