Pulmonary system- contains tissues and organs specialized for taking in oxygen and removing carbon dioxide from our bodies and for exchanging oxygen and carbon dioxide.
respiratory system
Lungs and Lungs. Blood that contains carbon dioxide means it is lacking oxygen, and the carbon dioxide was put into the blood as a waste product by all the other organs. The blood then reaches the lungs and exchanges the carbon dioxide for oxygen. The now oxygen-rich blood is transported to the heart where it is pumped throughout the body, and the carbon dioxide is exhaled from the lungs.
Oxygen and carbon dioxide change in the lungs.
Carbon.
The heart pumps and circulates blood, which transports oxygen and nutrients to all tissues in the body - and transports away wastes (such as carbon dioxide and other waste products) to the eliminatory organs.
The main organ of the circulatory system is the heart, and it pumps blood to the cells of organs and tissues, giving them oxegyn and removing carbon dioxide.
All of them. Carbon dioxide is produced by cellular respiration, which occurs in all organs.
The circulatory system imports oxygen and exports waste materials or carbon dioxide. The circulatory system distributes fresh oxygen to the tissues and organs of the body.
