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.
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.
Hemoglobin is a protein in red blood cells that carries oxygen from the lungs to the body's tissues and organs, and then carries carbon dioxide back to the lungs to be exhaled. It plays a crucial role in the body's ability to transport oxygen and maintain normal function of tissues and organs.
Carbon dioxide levels are typically highest in the tissues of the body, particularly in areas with high metabolic activity, such as muscles and organs. As cells metabolize oxygen to produce energy, they generate carbon dioxide as a waste product. This CO2 then diffuses into the bloodstream, where it is transported to the lungs for exhalation. Thus, the concentration of carbon dioxide is generally greatest in the venous blood returning from the tissues.
The respiratory system is responsible for exchanging oxygen and carbon dioxide between the body and the environment. This process primarily occurs in the lungs where oxygen is taken in and carbon dioxide is expelled. Other organs involved include the nose, trachea, and bronchial tubes.
Carbon.
The lungs are responsible for taking in oxygen through the process of inhalation and getting rid of carbon dioxide through exhalation. Oxygen is transported in the blood to various tissues in the body, while carbon dioxide is carried back to the lungs and exhaled out of the body.
The lungs are the primary organs that take in oxygen and remove carbon dioxide from the body. Oxygen is taken in through the process of inhalation, and carbon dioxide is removed through exhalation.
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 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.
