Cellular oxygen deficiency, also known as hypoxia, occurs when there is inadequate oxygen supply to the cells. This can lead to impaired cellular function and damage, affecting the normal functioning of tissues and organs. Severe or prolonged oxygen deficiency can cause tissue injury and organ failure.
Tiny blood vessels are called capillaries. They have thin walls that allow for the exchange of oxygen, nutrients, and waste products between the blood and surrounding tissues.
Red blood cells release oxygen molecules in the capillaries of body tissues where they are needed for cellular respiration. The oxygen diffuses from the red blood cells into the surrounding tissues due to the concentration gradient between the red blood cells and the tissues.
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.

anemia
The deficiency of oxygen is called hypoxia, which can occur when there is a decrease in the oxygen supply to tissues in the body. This can lead to symptoms such as shortness of breath, confusion, and eventually organ damage if left untreated. Treatment usually involves providing supplemental oxygen to the individual.
Hypoxia is a condition where there is a deficiency of oxygen in tissues. Inability to utilize oxygen effectively can be due to conditions like mitochondrial dysfunction or respiratory chain disorders, leading to cellular oxygen deprivation even when it's available in sufficient amounts.

hypoxia
Oxygen is transported to the tissues by red blood cells through the circulatory system. Hemoglobin in red blood cells binds to oxygen in the lungs and carries it to the tissues throughout the body. At the tissue level, oxygen diffuses from the capillaries into the surrounding cells for cellular respiration.
Two possible causes of inadequate delivery of oxygen to body tissues include reduced concentration of oxygen in the air, such as at high altitudes or in poorly ventilated areas, and impaired oxygen-carrying capacity of red blood cells due to conditions like anemia.
Tiny blood vessels are called capillaries. They have thin walls that allow for the exchange of oxygen, nutrients, and waste products between the blood and surrounding tissues.
We breathe air containing oxygen into our lungs. Once in the lungs, oxygen molecules pass into the blood vessels surrounding the alveoli where they bind to hemoglobin in red blood cells and are carried to body tissues. Oxygen is then used by cells in a process called respiration to produce energy.
Red blood cells release oxygen molecules in the capillaries of body tissues where they are needed for cellular respiration. The oxygen diffuses from the red blood cells into the surrounding tissues due to the concentration gradient between the red blood cells and the tissues.
Oxygen in the air diffuses into the lungs through tiny air sacs called alveoli. From there, it is picked up by red blood cells in the capillaries surrounding the alveoli through a process called gas exchange. The oxygen binds to hemoglobin in the red blood cells and is then transported to body tissues.
Oxygen moves from the lungs to the blood through a process called diffusion. This occurs at the alveoli in the lungs, where oxygen in the air sacs diffuses across the alveolar membrane into the capillaries surrounding the alveoli. From there, the oxygen binds to hemoglobin in red blood cells for transport to the body's tissues.
