What does oxygen diffuse into?
Oxygen diffuses from any place there is a lot of it to any place where there is less. In the body, it diffuses from the air in the alveoli of the lungs, through the lung and capillary walls and into the blood, where it is taken up by the haemoglobin of the red blood cells. When the bood reaches the body tissues it diffuses out of the blood and into the cells.
What is oxygens function in the body?
Oxygen is one of the most vital components of the blood. Oxygen bonds with iron in the haemoglobin, that is how it is carried to the cells for exchange with CO2.
How does perfluorooctyl bromide supply oxygen to tissues?
It has tiny nanites in it that replace all the blood in a person's body. Unfortunately, the nanites soon develop conciousness, and take over the host.
How do you use Haemoglobin in a sentence?
Haemoglobin is important for body.
Why do we have iron in our bodies?
Iron is part of the substance haemoglobin. This is the substance in red blood cells which enables us to carry oxygen around the body.
What lack of protein will decrease oxygen supply to body tissues?
hemoglobin
How is hemoglobin important for the body?
Each molecule of hemoglobin combines with 4 oxygen molecules to carry oxygen from the lungs through the bloodstream to the organs.
Why hemoglobin is better long distance oxygen transporter than myoglobin?
Both Myoglobin and Haemoglobin binds to oxygen, but they differ in many aspects. Usual site: Myoglobin: muscle tissues Haemoblogin: red blood cells (whole body) Main function: Myoglobin: stores oxygen (in muscle tissues) Haemoglobin: Oxygenation of tissues (whole body) Waste (CO2) collection (whole body) gas exchange (lungs, tissues) Oxygen carrying capacity: Myoglobin: monomeric = one heme prosthetic group, one iron atom Haemoglobin: tetrameric = four heme prosthetic groups, four iron atoms. Structure Myoglobin: secondary and tertiary, no allosteric interaction Haemoglobin: quaternary structure, allosteric interaction, different affinity Affinity to oxygen Myoglobin: Oxidation (Fe2+ → Fe3+) prevents oxygen binding. Haemoglobin: requirement specific affinity: (gradually increasing in the lungs, . gradually decreasing at the tissues) Prefered binding Myoglobin: Carbon monoxide preferred to Oxygen. Haemoglobin: Oxygen, carbon dioxide While in cases of hugely increased demand, myoglobin releases oxygen for metabolism, but, in the long run haemoglobin is more suitable for the purpose.
Why is fetal hemoglobin unsuitable to use after birth?
Fetal haemoglobin has a higher affinity for oxygen, so is less able to dissociate than maternal haemoglobin within body tissues and cells.
What does the vascular system do?
Pumps blood around the body, to supply the tissues with oxygen and nutrients and to transport waste products away from these tissues.
What do vascular systems do?

How does the increase in red blood cell production improve performance?
Red blood cells are the oxygen carriers of the body. They are made in the red bone marrows in the human body. Red blood cells contain the red pigment haemoglobin which combines with oxygen to makeoxyhaemoglobin and is broken down back again into oxygen and haemoglobin, where needed. Haemoglobin is very useful in carrying oxygen from the lungs to the tissues. Oxygen is needed for our cells and almost all our bodily activities. Oxygen is used in aerobic respiration which releases about 2830 Kilojoules of energy. So, the increase in red blood cells helps the body to bring in more oxygen and so improve performance as it increases respiration. This will help to keep the body active and will provide the body with more energy as we get exercise. If there are more red blood cells, containing haemoglobin in our blood, it allows more oxygen to dissolve in the blood and supply the active muscles.
What is the jobs of blood?
Blood transports oxygen (and carbon dioxide) and nutrients throughout your body to your tissues
Why is haemoglobin red?
haemoglobin is red because is carrys oxygen around our body when blood is in contact with oxygen it turns red same
Which supplies oxygen to other parts of the body?
The haemoglobin in the blood, transports oxygen around the body.
Does anaemia make you weak?
Yes anaemia can make you weak. This is because the body has a lower number of haemoglobin molecules, which are the molecules in red blood cells which carry oxygen around the body. Therefore, the body tissues are receiving less oxygen and can not work as effectively.
What is the importance of haemoglobin in the blood cells?
Haemoglobin carries oxygen around the body, and removes carbon dioxide.
