At tissue cells, the oxygen dissociation reaction involves the release of oxygen from hemoglobin in red blood cells. When blood reaches the tissues, the lower partial pressure of oxygen and higher levels of carbon dioxide and acidity promote the release of oxygen from hemoglobin, a process known as the Bohr effect. This allows oxygen to diffuse from the blood into the surrounding tissues, where it is utilized for cellular respiration.

What is the dissociation reaction that occurs at the tissue cells?

At tissue cells, the dissociation reaction primarily involves the release of oxygen from hemoglobin in red blood cells. This process occurs as oxygen binds reversibly to hemoglobin in the lungs and is then released in tissues where the oxygen concentration is lower and carbon dioxide concentration is higher. The presence of carbon dioxide and protons (H+) in tissues shifts the hemoglobin-oxygen binding curve, promoting oxygen release to meet the metabolic needs of the cells. This is known as the Bohr effect, facilitating efficient oxygen delivery where it is most needed.


Lack of blood to a tissue fed by blocked arteries is called?

Ischemia. It occurs when the blood supply to a tissue is restricted or blocked, leading to a decrease in oxygen and nutrient delivery, which can result in tissue damage or cell death.


What handles tissue exchange?

In the body, the circulatory system handles tissue exchange by transporting oxygen, nutrients, and waste products to and from cells. This exchange occurs through the blood vessels, where oxygen and nutrients are delivered to tissues, and waste products are carried away.


What is an area of tissue that becomes necrotic due to a lack of O2 called?

An area of tissue that becomes necrotic due to a lack of oxygen is called an infarct. This typically occurs when the blood supply to a specific area is blocked, leading to tissue death.


What is tissue hypoxia?

Tissue hypoxia is a condition where there is an inadequate supply of oxygen to the cells. This can lead to cell damage and dysfunction, impacting the normal functioning of tissues and organs. Conditions such as heart failure, respiratory diseases, and circulatory problems can contribute to tissue hypoxia.

What is low tissue oxygen levels called?

Low tissue oxygen levels are called hypoxia. This condition occurs when there is a decreased level of oxygen available to the body's tissues and cells, resulting in potential damage and impairment of normal function.


What is the area of dead tissue affected by a heart attack called?

The area is known as a foci of necrotic tissue, eventually turning into fibrosed (scar) tissue. The process by which this occurs is tissue ischaemia (where not enough oxygen is supplied to the heart tissue to meet its requirements).


Why does an increase in temperature cause the oxygen dissociation curve to shift to the right?

when we excercising, tissue generates heat.those heat would increase the temperature of the neighboring cell, that exercise and need more energy. thus, more oxygen is needed, making the graph shift to the right because hemoglobin release oxygen faster to accord the increasing demand during exercise.

How does carbon dioxide affect the level of oxygen in the blood?

When carbon dioxide levels rise in the blood, it can lead to a decrease in pH, known as acidosis. This can cause a rightward shift of the oxygen-hemoglobin dissociation curve, making it harder for hemoglobin to release oxygen to tissues. As a result, less oxygen may be available to cells, leading to potential tissue hypoxia.

How does oxygen diffuse through the body?

Diffusion occurs throughout the human body, and without it, cells and body tissue, dirty atmosphere, oxygen concentration may be low, and the eye can dry out.

Where do Metabolites exchange by diffusion with tissue cells?

Metabolites exchange by diffusion with tissue cells at the capillaries in the circulatory system. Capillaries are the smallest blood vessels where the exchange of nutrients, oxygen, and waste products occurs between the blood and the surrounding tissue cells.
