Cilia Are Tiny Hairs Of The Respiratory Tract By Capturing Particles

Since Cari is a smoker, cigarette smoke has paralyzed her cilia and stimulated the goblet cells lining her respiratory passages to secrete excess amounts of mucus. Ducts from the sinuses open into the internal nose providing a passageway for microorganisms to travel into the sinuses.

3. Name the structure that is a double fold of peritoneum and holds the small intestine to the

C. Which structures found in the terminal bronchioles and alveoli normally would protect Cari’s lungs from infectious pathogens and particulate matter?

3-7: The cells of the connective tissue pictured below in a cross section from the trachea are specialized for fat storage and do not form ground substance or fibers.  On prepared slides, this type tissue appears somewhat like a fish net with white spaces connected together in a network.  The cytoplasm and nucleus have been pushed to one side by a single, large, fat-filled

The stomach is an organ that is part of the digestive system. The stomach is located in the upper left part of the abdominal cavity, below the diaphragm and next to the liver (Stomach, 2013). The inner walls of the stomach contain small pores called gastric pits. The gastric pits contain cells that secrete chemicals that aid in the digestion of food (Nguyen, 2015). In this essay, I will discuss the different cell types of the stomach, how they work together to provide the overall function of the stomach, why each organ requires different cell types, why the stomach can’t be comprised of just one cell type, and the advantage of having different types of cells.

It contains many circular folds that increase the surface area of the functional mucous membrane. Enterocytes are cells found in the upper part of each villus and secrete enzymes for the digestion and absorption of fats, carbohydrates, and proteins. Not having the villi within the inner surface of small intestine makes the body is unable to absorb nutrients essential for health and growth. Instead, nutrients such as fat, protein, vitamins, and minerals are eliminated in the stool (NIDDK, 2018).

Epithelium – Epithelium tissues are composed of layers of the cells that are closely packed together which is specialised to form the covering or lining of both external and internal surface of body such as surface of your skin and internal digestive system. The main function of epithelium tissues are to provide protection like skin that protects you from injury, secretion like glands such as enzymes, and to absorb materials like intestine such as waste products etc.

The mucous membrane lines the nasal cavity that has pseudo stratified ciliated epithelium richer mucus- secreting goblet cells. These include a more extensive network of blood vessels and appear pink. Heat is radiated over the membrane when air passes over it from blood and warms the air, changing the temperature of the body. Evaporation of water from the mucous lining moistens the air during the same time. Sticky mucus is secreted by mucous membranes that entrap dust and other particles that enter the

Transitional epithelium is also composed of several layers but is constructive of pear shaped cells instead. This type of tissue is stretchy, meaning it can contract and expand. It is usually found lining the urinary bladder as it allows for stretching as the bladder fills up.

Consist of oral cavity, esophagus, gallbladder, liver, stomach, duodenum, pancreas, colon, cecum, appendix, jejunum, and rectum.

It is also often referred to as the "windpipe." The trachea then branches off like a tree. The first splits of this "tree" are the bronchi, and the smallest branches are called the bronchioles. Thus after air travels through the trachea, it then reaches the bronchi, and spreads throughout the bronchioles.

Now, what does it do you may be asking? These tiny things provide a lot for many unicellular eukaryotes. The main function of both of these organelles is movement which is powered by ATP. Cilia beat in unison on the outside of the cell in a whip like motion. Flagella have a rotational movement which makes them also act as whips to allow cells to swim through fluids. Cilia allows the cells to move through water, being locomotor appendages. Also, when the cilia is a part of a cell that is bound to one place, they will aid in the movement of water over itself. Other than movement, cilia and flagella act as sensory organelles, receiving information from outside the, like different chemicals and temperature, and informing the cell about what

Cilium plays a significant role in the cause of PKD. Cilia are microtubules located on the surface of most eukaryotic cells. There are two different kinds of cilia. The first one is the motile-cilia and the second is the non-motile-cilia or ‘primary’. Motile-cilia mostly help with movement. They mostly found on the respiratory tract and middle ear. Also they help push sperm. In the other hand the non-motile-cilia are working as a sensory antenna for the cells as well as signaling between cells. Non-motile-cilia act as sensory for the concentrations of calcium flow and growth factors. In addition, the non-motile-cilia in the kidney called kidney tubules. As seen in PKD, an irregularity of non-motile cilia is the cause of abnormal cell

Cilia are hair like structures that stick out from the surface of a cell. Cilia are found in the lungs, respiratory tract and ear. They help to keep human and animal airways clear of mucus and dust, which permits us to breathe effortlessly and they also help propel semen. They also act as a sensory antenna for the cell. Some of the symptoms PCD can cause are chronic respiratory tract infections, unusually positioned interior organs, and

These are pyramidal-shaped areas which are also separated from each other by membranes. There are about 10 of them in each lung. Each segment receives its own blood supply and air supply.
