What else can I help you with?
Most of the gi tract is composed of blank epithelium?
Most of the GI tract is composed of simple columnar epithelium. This type of epithelium is well-suited for secretion and absorption processes due to the presence of microvilli, which increase the surface area available for these functions.
What is the microscopic hairlike projections found in the cells lining most of the respiratory tract called?
Cilia are the microscopic hairlike projections found in the cells lining most of the respiratory tract. They help to sweep mucus and trapped particles out of the airways to protect the lungs from infections and irritants.
What would happen if the digestive tract was lined with stratifed squamous epithelium instad of simple columnar epithelium?
Through stratified squamous epithelium absorption will be very poor and person will die of starvation.Malabsorption could occur if the digestive tract were lined with stratified squamous epithelium instead of simple columnar eqithelium.
What does rsv stand for in rsv virus?
RSV stands for respiratory syncytial virus, the most frequent cause of serious respiratory tract infections in infants and children younger than 4 years of age. RSV causes nasal stuffiness and discharge, cough, and sometimes ear infections.
What portion of the body houses most of the viral organs?
Viruses typically infect cells in various organs throughout the body, rather than being specifically housed in one particular area. However, the respiratory tract, gastrointestinal tract, and blood are common sites where viruses can replicate and cause infections.
What tissue lines most of the respiratory tract?
The tissue lining your inner nasal passages is made from ectoderm. However, the rest of the respiratory tract lining is made of endoderm.
What type of epithelium lines the small intestine?
The intestinal epithelium, which covers the small and large intestine, is simple columnar and nonciliated. It lines most of the organs of the digestive tract.
Most of the gi tract is composed of blank epithelium?
Most of the GI tract is composed of simple columnar epithelium. This type of epithelium is well-suited for secretion and absorption processes due to the presence of microvilli, which increase the surface area available for these functions.
Where would pseudostratified columnar epithelium be found?
lines the ducts of some glands and portions of the male urethra
Lines the stomach and most of the intestines?
Epithelial tissue lines the stomach, like most internal organs.
What is a description of Pseudostratified ciliated epithelium?
Pseudostratified ciliated epithelium is a type of epithelial tissue found in the respiratory tract. It appears to be stratified due to the nuclei being at different levels, but all cells are in contact with the basement membrane. Most of the cells have cilia on their apical surface, which help in moving debris and mucus out of the respiratory system.
What is the most common portal of entry for pathogens?
The three most common are the skin, gastrointestinal tract and respiratory tract
In humans what are the most common points of entry for infections?
Organisms can enter through the gastrointestinal tract,respiratory tract,genitourinary tract or even through the cutaneous route.
Where in the cell does cancer originate?
Up to 90% of all human cancers are circinomas, which are growths that originate in epithelium. Most carcinomas begin on surfaces that contact the external enviroment, such as skin, linings of the airways in the respiratory tract, or linings of the stomach or intestines in the digestive tract. This observation suggests that the more cancer causing agentsmay not penetrate tissues very deeply.
Which body system is most vulnerable to sulfur mustard exposure?
The respiratory system is most vulnerable to sulfur mustard exposure. When sulfur mustard is inhaled, it can damage the respiratory tract, causing inflammation, blistering, and potentially leading to respiratory failure.
Where is ciliated epithelium found?
Ciliated epithelium is located in the lining of most body cavities. Some of the cavities that have ciliated epithelium are the lungs, trachea, and nose. Ciliated epithelium serves to keep dust and debris out of the lungs and control the flow of mucus.in your lungs . Its The tissue in your lungs!!In the respiratory tractThe ciliated epithelium is a type of tissue located inside the nose. Cilia or nose hairs are situated on top of the ciliated epithelium and triggers sneezing when dust particles are caught in the cilia.In what organ will you find ciliated epithelium? Primarily in the trachea.
What are the smallest and most distal structures that remain a component of the conducting zone in the respiratory tract?
The smallest and most distal structures that remain a part of the conducting zone in the respiratory tract are the terminal bronchioles. These bronchioles are the final branches of the conducting airways before reaching the respiratory zone where gas exchange occurs in the alveoli.
