Oxygen travels through the respiratory system. First, it enters through the mouth or the nasal cavity. Then, it goes down the trachea, or the windpipe, and into the lungs, where it is brought into the blood by the alveoli. Carbon dioxide is also exiting out of the body through the same way, but backwards.

How is oxygen transported by blood from lungs to tissues?
Oxygen is transported by blood from the lungs to tissues primarily by binding to hemoglobin in red blood cells. Hemoglobin carries oxygen from the lungs to tissues where it is released for cellular respiration. Through this process, oxygen diffuses from high concentrations in the lungs to areas with lower concentrations in the body tissues.
How does haemoglobin supply the tissues of the body with oxygen?
Hemoglobin carries oxygen in red blood cells from the lungs to the tissues of the body. In the lungs, oxygen binds to the iron in hemoglobin to form oxyhemoglobin, which is then transported via the bloodstream to tissues where oxygen is released for cellular respiration. This process is facilitated by the concentration gradient of oxygen between the lungs and tissues.
What do red blood cell transport from tissues?
Red blood cells transport oxygen from the lungs to the tissues and remove carbon dioxide from the tissues back to the lungs for exhalation.
Capillaries are to body tissues as are to lungs?

How red blood cells transport oxygen from lungs to tissue?
Red blood cells transport oxygen from the lungs to tissues through the protein hemoglobin, which binds to oxygen in the lungs and releases it in tissues. This process is facilitated by the high concentration of oxygen in the lungs and lower concentration in tissues, creating a gradient for oxygen to be transported. The shape and characteristics of hemoglobin allow for efficient binding and release of oxygen as needed by the body.
How is oxygen moved from the lungs to the tissues?
Oxygen is transported from the lungs to the tissues through the bloodstream. It binds to hemoglobin molecules in red blood cells, forming oxyhemoglobin. The heart pumps oxygen-rich blood through arteries to the tissues, where oxygen is released for cellular respiration.
What transport oxygen and carry away carbon dioxide?
concave disks
What happens after oxygen leaves the lungs?
After oxygen leaves the lungs, it enters the bloodstream through the alveoli in the lungs. It then travels to the heart, which pumps the oxygen-rich blood to various tissues and organs in the body. The oxygen is used by cells in these tissues and organs for energy production through a process called cellular respiration.
What is the major function of the lungs in a human body?
The major function of the lungs is gas exchange. Gas exchange requires the entire cardiopulmonary system which includes the heart, lungs, and blood vessels (arteries,arterioles,capillaries,veins),. At the capillaries which is the smallest vessels with thin walls permitting diffusion and gas exchange the carbon dioxide (C02) and oxygen (02) are exchanged. It is the capillaries that allows tissues to be supplied with the essential oxygen that they need and allows the tissues get rid of the toxic waste products including C02. The waste products will travel back to the veins, back to the heart where they then go to the lungs and are expired. When an individual inhales, the oxygen is taken in via alveoli in the lungs, travel to the heart then to the arteries and then to the tissues. and the cycle continues...
What is the function of heomoglobin?
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.
How oxygen is transported through the circulatory system?
Oxygen is transported through the circulatory system by binding to hemoglobin in red blood cells. Hemoglobin carries the oxygen from the lungs to the tissues in the body where it is needed for cellular respiration. The oxygen is released from hemoglobin and diffuses into the surrounding tissues to support their metabolic functions.
What is a chemical that carries oxygen and carbon dioxide?
Hemoglobin
