P2 Outline the Main Tissues Of The Body Epithelial Epithelial tissue is basically the linings of both the internal and external surfaces of the body and can be divided into two groups. The groups depend upon the number of layers of which it is composed. These two groups are simple epithelial and compound. Simple squamous are thin, flat plates and their main function is osmosis (which is the passage of water molecules from a region of low concentration to one of high concentration through a semi-permeable membrane) and diffusion (which is the passage of molecules from a high concentration to a low concentration). They form the lining of cavities such as the mouth, blood capillaries, heart and lung alveoli and make up the outer layers of the skin.
If each membrane is damaged, the epithelium would not be able to be held up because the lamina propia is what supports the epithelium. If the serous membrane is damaged, then there would be friction with movement. Ref: http://answers.yahoo.com/question/index?qid=20130111145200AASxqqI 3.Tattoos are fairly common among individuals. With your knowledge of the integument; please explain why tattoos are permanent? How are Henna tattoos different from "traditional" tattoos?
Compound Epithelium – this type of epithelial tissue is made to withstand wear and tear. It is composed by several layers of cells which is the reason for the name of the cell. The epithelium may or may not be keratinised which contains a tough, resistant protein called keratin for example skin or unkeratinised which is what the lining of your mouth is made up of. Unstriated muscle – this is the type of muscle which still contains protein filaments but they do not lie in an orderly pattern as with striated muscle. In this type of muscle the fibres are spindle shaped and generally have a central nucleus, and dove-tail into each other.
Muscular Tissue 2. Which type of cell junction functions in communication between adjacent cells? Gap Junctions 3. If epithelial tissue is avascular, how do nutrients and oxygen get to the tissue and waste products leave? By diffusion between the epithelium and underlying connective tissue 4.
Distention for many involuntary digestive movements. c. What do ANS neurons regulate with regard to mechanical digestion? What are the possible responses? The ANS neurons regulate involuntary smooth muscular movements. The response is either increased or decreased contraction of the muscularis.
Single membrane compartment organelles include the endoplasmic reticulum and Golgi apparatus. Ribosomes don’t have a membrane. The breakdown of the membranes of these structures affect the function of the heart because lysosomal enzymes are normally bound safely inside vesicles that will digest the plasma membranes and the membranes of the organelles. Question D: Two important pieces of information- The instructions Joseph’s body needs to repair itself and his predisposition for vascular disease-are both contained within the cell on which structures? (A) Joseph’s predisposition means that he inherited vascular disease which is held in the
Epithelial tissues line the cavities and surfaces of structures throughout the body, and also form many glands. Functions of epithelial cells include secretion, selective absorption, protection, cellular transport and detection of sensation. Epithelial layers are avascular, meaning they contain no blood vessels and rely on underlying vascular tissues to absorb nutrients from. Epithelia can also be organized into clusters of cells that function as exocrine and endocrine glands. Exocrine and endocrine epithelial cells are highly vascular.
Anthrax spores that contaminate article or rail can remain effective for years. Anthrax happens in three different forms: cutanex anthrax(malignant postule),the most common (95%), inhalation anthrax which is rare (5%), the other , gastrointestinal anthrax, which has never been reported in the United States. 106,000 anthrax cases are reported annually
First degree burns tend to heal in 2-3 days without special treatment. Examples of a first degree burn would be sun burn. The second type of burn is the second degree burn which injures the epidermis and the upper region of the dermis. Symptoms may include things like redness, pain in the area and also include blisters. Skin generation occurs with little or no scarring First and Second Degree burns refer to the partial-thickness burns.
This system contains two major types of neurons: sensory neurons (or afferent neurons) that carry information from the nerves to the central nervous system, and motor neurons (or efferent neurons) that carry information from the brain and spinal cord to muscle fibers throughout the body. The Autonomic Nervous System The autonomic system is the part of the peripheral nervous system responsible for regulating involuntary body functions, such as blood flow, heartbeat, digestion and breathing. This system is further divided into two branches: the sympathetic system regulates the flight-or-fight responses, while the parasympathetic system helps maintain normal body functions and conserves physical
