The tissue that always has a free surface exposed to the internal or external environment?
Epithelial tissue is the type of tissue that always has a free surface exposed to the internal or external environment. This tissue serves as a protective barrier or lining for organs and cavities in the body.
Where do growth factors, essential for cellular development and tissue repair, originate from in the human body?
Growth factors, important for cell growth and tissue repair, are produced in the human body by various cells, including platelets, fibroblasts, and macrophages.
What is non epithelial cell?
It means that the cells that line structures were found, but they were not the type found in the kidneys.
Type of tissue that covers the body surface?
Epithelial tissue covers the body surface. It serves as a protective barrier against physical, chemical, and microbial damage and helps regulate the exchange of substances between the body and its environment.
What are four common classes of malignant tumors?
Melanomas Lymphomas Sarcomas Carcinomas
What hazard is tissue preserver?
Tissue preserver can be a hazard if ingested or inhaled, as it may contain toxic chemicals that could cause harm to the body. It is important to handle tissue preserver with care, following safety guidelines and precautions to prevent any adverse health effects.
What is the medical term meaning the protective mechanism that blocks chemicals from entering brain tissue?
The blood brain barrier blocks chemicals from entering brain tissue.
What gives chemical to the body tissue-?
One thing that gives chemicals to the body tissue is ingestion. A person can drink anything liquid and have the chemicals in the drink, for instance caffeine, enter into the blood stream.
Which chemicals are capable of causing a severe tissue reaction?
Examples: strong acids, strong bases, radioactive chemicals.
The tissue that always has a free surface exposed to the internal or external environment?
Epithelial tissue is the type of tissue that always has a free surface exposed to the internal or external environment. This tissue serves as a protective barrier or lining for organs and cavities in the body.
What type of cancer affects the lymph tissue?
Hodgkin's disease effects lymph tissue
Which tissue links your external environment with your internal environment?
Blood Plasma.
Do most intracranial tumors originate directly in brain tissue yes or no?
Yes, the majority do.
What Chemicals that attack living tissue and cause disease in humans. These chemicals are called?
These chemicals are called "toxins" or "toxicants." They can originate from various sources, including plants, animals, and synthetic compounds, and they can cause damage to living tissues, leading to diseases in humans. Examples include heavy metals like lead and mercury, as well as certain biological toxins produced by bacteria and fungi. Exposure to these chemicals can result in a range of health issues, from acute poisoning to chronic diseases.
Can the epithelial tissues be called semipermeable membrane?
Yes, a semipermeable membrane selectively allows chemicals to be absorbed into the body. Epithelial tissue covers all parts of the body that has contact to the the outside environment including the gastric tract. One prime example of semipermeable epithelial tissue of the body is the tissue of the intestines which has folds exactly for the purpose of absorbing food.
In adults new connective tissue cells originate from what?
In adults, new connective tissue cells primarily originate from mesenchymal stem cells, which are multipotent stem cells found in various tissues. These cells can differentiate into various types of connective tissue cells, including fibroblasts, adipocytes, and chondrocytes. Additionally, some connective tissue cells can also arise from the proliferation of existing cells within the tissue itself.
What tissue type enables us to be aware of the external environment and react to it?
nervous tissue
