OXYGEN
The protein in blood that helps carry oxygen is called hemoglobin. Hemoglobin is located within red blood cells and binds to oxygen in the lungs, transporting it to tissues throughout the body.
Oxygen is essential for aerobic respiration, oxygen helps blood flow which helps with our circulation. Anaerobic respiration does not require oxygen.
IRON
It helps supply blood to the stomach to digest food. It helps move nutrients that is absorbed in the blood to surrounding tissues and muscles.
Hemoglobin, a protein found in red blood cells, helps to absorb and transport oxygen throughout the body. Hemoglobin binds to oxygen in the lungs and releases it to tissues that need oxygen for energy production.
Hemoglobin, a protein found in red blood cells, helps deliver oxygen to the blood by binding to oxygen molecules in the lungs and releasing them to tissues throughout the body. Additionally, the respiratory system's process of inhaling oxygen and exhaling carbon dioxide facilitates the transfer of oxygen into the bloodstream.
No, oxygen does not dilate blood vessels. In fact, oxygen has a vasoconstrictive effect, which means it causes blood vessels to constrict or narrow. This helps regulate blood flow and pressure in the body.
