Oxygen is transported to the respiring tissues through the bloodstream. It is first inhaled into the lungs, where it diffuses into the blood vessels in the alveoli. Hemoglobin in red blood cells binds to the oxygen, allowing it to be carried throughout the body and released to cells in need of oxygen for respiration.

How does oxygen reach to the tissues?
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.
Where do the red cells drop the oxygen off?
Red blood cells drop off oxygen to tissues and cells in the body through the process of diffusion in capillaries. Oxygen molecules bind to hemoglobin in red blood cells in the lungs and are released when the red blood cells reach tissues with lower oxygen concentration.
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.
Is po2 what supplies tissues with oxygen?
Yes, the partial pressure of oxygen (pO2) in the blood is what drives the diffusion of oxygen from the lungs to the tissues in the body. This oxygen is carried by red blood cells and released to tissues where it is needed for various cellular functions.
How long does it take for oxygen to travel around the body?
Oxygenated blood travels through the body in around 20-30 seconds, delivered by the heart through the circulatory system to reach all the tissues and organs where it is needed for cellular respiration. The process involves the heart pumping oxygen-rich blood from the lungs to tissues, where oxygen is exchanged for carbon dioxide.
What is the difference between the two types of respiration?
External respiration refers to the exchange of gases between the lungs and the blood, while internal respiration is the exchange of gases between the blood and the tissues. External respiration involves the intake of oxygen and release of carbon dioxide in the lungs, while internal respiration occurs in the body's tissues.
How oxygen is passed from a red blood cell to an actively respiring muscle?
The oxygen passes through a bloodvessel called artery to an actively respiring muscle cell.
Does anaerobic respration means respiring without oxygen?
no
How does oxygen reach to the tissues?
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.
What are the reactants and products in a respiring cell?
oxygen + glucose = Carbon dioxide + water
What does the body do after oxygen debt rises?
It get back to normal by respiring more frequently.
In what circumastances would a human start respiring anaerobically?
when a person hasn't got enough oxygen
Where do red blood cells drop off oxygen?
Red blood cells release their oxygen in the capillaries. The oxygen diffuses across the capillary wall to reach the body tissues.
Where do the red cells drop the oxygen off?
Red blood cells drop off oxygen to tissues and cells in the body through the process of diffusion in capillaries. Oxygen molecules bind to hemoglobin in red blood cells in the lungs and are released when the red blood cells reach tissues with lower oxygen concentration.
Do the red blood cells pick up oxygen in the lungs?
Yes, red blood cells pick up oxygen in the lungs through a process called oxygenation. Oxygen binds to hemoglobin, a protein in red blood cells, and is then carried to tissues throughout the body for cellular respiration.
Is respiring a life process?
Yes, respiring is a life process because it involves the exchange of gases, such as oxygen and carbon dioxide, which are necessary for sustaining life. Cells respire to produce energy in the form of ATP, which is essential for carrying out various biological functions.
How do tissues get the oxygen they need for energy production?
The tissues get oxygen from oxygenated blood supply for energy production.
