The constant turnover of body tissue requires the energy supplied by adenosine triphosphate (ATP) produced by cellular respiration. This energy is essential for various cellular processes, including growth, repair, and maintenance of tissues. Additionally, nutrients supplied by the bloodstream are crucial for synthesizing new cellular components.

What is tissue turnover?
Tissue turnover refers to the continuous process of cells being replaced in a tissue. Old or damaged cells are removed and replaced with new cells through cell division and differentiation, ensuring the tissue remains healthy and functional. Examples of tissues with high turnover rates include the skin and the lining of the digestive tract.
Which type of tissue regenerates the best?
Epithelial tissue has the best regenerative ability due to its high turnover rate and constant cell division. Skin and mucous membranes are examples of epithelial tissues that regenerate quickly to maintain barrier functions.
Cardiac muscle tissue is supplied with nutrients and oxygen by which part of the human transport system?
Cardiac muscle tissue is supplied with nutrients and oxygen by the coronary arteries, which branch off the aorta and supply blood to the heart muscle. These arteries ensure adequate delivery of oxygen and nutrients to the heart for proper function.
What does the tissue lability depend uponn?
Tissue lability depends on factors such as the turnover rate of cells, their regenerative capacity, and the presence of stem cells. Tissues with higher cell turnover rates, good regenerative potential, and abundant stem cells are considered more labile and capable of rapid repair and regeneration in response to damage or injury.
Is your epidermal tissue constantly being replaced throughout life?
Yes, the epidermal tissue, which is the outer layer of the skin, is constantly being replaced throughout life through a process called skin cell turnover. This turnover helps to shed old, dead skin cells and replace them with newer cells to maintain skin health and integrity.
Which type of tissue is characterized by continuous loss and replacement?
Epithelial tissue is characterized by continuous loss and replacement due to the high rate of cell turnover. This tissue is found covering body surfaces and lining body cavities, where constant renewal is necessary to maintain function and protection.
What is tissue turnover?
Tissue turnover refers to the continuous process of cells being replaced in a tissue. Old or damaged cells are removed and replaced with new cells through cell division and differentiation, ensuring the tissue remains healthy and functional. Examples of tissues with high turnover rates include the skin and the lining of the digestive tract.
What does increased bone turnover mean?
Bone remodeling is a lifelong process where mature bone tissue is removed from the skeleton and new bone tissue is formed. This is also known as bone turnover.
Which type of tissue regenerates the best?
Epithelial tissue has the best regenerative ability due to its high turnover rate and constant cell division. Skin and mucous membranes are examples of epithelial tissues that regenerate quickly to maintain barrier functions.
Skin is supplied with oxygen and nutrients by the?
Underlying connective tissue
Which body structure requires the most brain tissue?
Only the brain will have brain tissue
Cardiac muscle tissue is supplied with nutrients and oxygen by which part of the human transport system?
Cardiac muscle tissue is supplied with nutrients and oxygen by the coronary arteries, which branch off the aorta and supply blood to the heart muscle. These arteries ensure adequate delivery of oxygen and nutrients to the heart for proper 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).
What happens to bone tissue if not used?
It is technically impossible to NOT "use your bone tissue". Because the skeleton is built of bone tissue it is in constant use.
The periosteum is a tissue that serves only to protect the bone because it is not supplied with nerves or blood vessels?
false
What does the tissue lability depend uponn?
Tissue lability depends on factors such as the turnover rate of cells, their regenerative capacity, and the presence of stem cells. Tissues with higher cell turnover rates, good regenerative potential, and abundant stem cells are considered more labile and capable of rapid repair and regeneration in response to damage or injury.
How do bones respond to disuse such as constant bed rest?
atrophy of tissue
