Oxygen is carried in your blood stream by the red blood cells. Within the red blood cell there is a specialised protein molecule called Haemoglobin.
Red blood cells are specialised to carry oxygen through their lack of a nucleus giving them a biconcave shape and increasing their surface area. The red colour comes from the presence of iron in the haemoglobin molecules.
When the blood enters the lungs it is only ever one cell away from the air within the lungs. The constant flowing of the blood and the constant tidal flow of air in and out of the lungs ensures a concentration gradient is maintained at all times. This concentration gradient leads to carbon dioxide leaving the blood and oxygen entering it all by simple diffusion.
Blood is transported around the body by the pumping of the heart. The constant flow also helps to maintain a concentration gradient and encourages oxygen to disassociate from the oxyhaemoglobin complex within the red blood cells when the blood flows past areas of low oxygen concentration.
During times of high activity the muscles are respiring at an increased rate. This increase produces a corresponding increase in the amount of oxygen required and the amount of carbon dioxide produced. This is compensated for by an increased heart rate and the fact that oxygen will diffuse more rapidly in these situations.
As the blood flows past the muscles oxygen diffuses into the muscle tissue. If the oxygen is not immediately required it can be stored in myoglobin in the muscle tissue.
Respiration is the production of ATP from ADP or AMP (Adenosine tri, di and mono phosphate respectively) a high energy molecule that serves as a currency for energy in cells.
Aerobic respiration requires oxygen and glucose and produces on average 30 molecules of ATP per molecule of glucose. Anaerobic respiration does not require oxygen but only produces 2 molecules of ATP per molecule of glucose; it also produces toxic lactic acid that needs to be metabolised in the presence of oxygen to avoid poisoning the body tissue.
Oxygen is carried to the muscles from the lungs by the blood.
Oxygen is carried to the muscles in the blood. The red blood cells in the blood have a hemoglobin molecule that has little receptor sites or "handles" that the oxygen binds to, to be carried to all parts of the body. Since blood goes to every muscle and every organ in your body, they are nourished by the 02.
When your red corpuscles go through the capillaries in your lungs, the oxygen attaches to the iron in your hemoglobin. This then goes through your heart and through your arteries into the capillaries into your muscles. When the capillaries squeeze the red blood cells, the give up their oxygen molecules. These molecules go into your muscles to provide energy.
What else can I help you with?
When a muscle starts working hard. How do you think oxygen and nutrient needs change?
Need more oxygen for respiration. more nutrients for muscle growth.
What takes oxygen to the working muscles?
well you all know that blood is really blue ,but once it hits air it turns red that's why when you get a cut ,before you had a cut the blood was blue , but once the blood comes out and it absorbs the air it turns red.So with that said when the blood circulates in the muscle the blood is red and full of oxygen so the blood gives the muscle oxygen every time blood passes through it keeps giving the muscle oxygen 24/7<3
Why is oxygen so critical to heart muscle?
Oxygen plays many roles in the metabolic pathways that support contracture of the heart's cardiac muscle tissue. The heart muscle is the only muscle in the body which is always working. It cannot stop and rest, because the body requires a constant circulation of blood, to supply the tissues of the body with oxygen and nutrients. The brain can only survive for 3 minutes without oxygen. So since the heart must constantly work, it requires a constant supply of oxygenated blood. Without it, the heart would not have the energy it requires to do its work, and would stop.
What role does the heart play in exercise?
the role of the heart is to supply the working muscle with oxygen and energy
What do red blood cells carry to the working muscles?
Red blood cells carry oxygen from the lungs to the working muscles. This oxygen is essential for aerobic metabolism, which is the process that provides energy for muscle contractions during exercise.
What causes the sound of peoples heartbeat after a workout?
the body is working extremely hard to force blood and the oxygen in the blood around the body, so by working harder you need more oxygen to travel around your muscle's, so your heart is working harder, therefore you need more oxygen.
How does muscle obtain oxygen?
well you all know that blood is really blue ,but once it hits air it turns red that's why when you get a cut ,before you had a cut the blood was blue , but once the blood comes out and it absorbs the air it turns red.So with that said when the blood circulates in the muscle the blood is red and full of oxygen so the blood gives the muscle oxygen every time blood passes through it keeps giving the muscle oxygen 24/7<3
When part of the heart muscle died from lack of oxygen and the entire organ stops working the result is?
heart attack
When part of the heart muscle dies from lack of oxygen and the entire organ stops working the result is?
A heart attack
What is the hardest working muscle in the human body and why?
The hardest working muscle in the human body is the heart. It continuously pumps blood throughout the body, delivering oxygen and nutrients to all other muscles and organs. The heart never stops working, even when we are at rest, making it the most vital and hardworking muscle in the body.
How does food and oxygen get to a muscle cell in your toe?
Well it doesn't actually carry food down there. The blood carries nutrients and oxygen to your extremities through capillaries. These are very tiny veins that branch off from the veins connected to your arteries. When you prick your finger or toe the blood that comes out is actually from one of these capillaries.
When air conditioner in vehicle working by closing external air inlet then will the amount of oxygen reduce if how oxygen content is maintained?
The general answer is "no, the oxygen in the vehicle compartment is unaffected by the air conditioning unit". The vehicle is not air-tight so while there may be a small decrease in oxygen content, sufficient oxygen for normal occupant breathing will remain.
