They are elongated and column shaped. The nuclei are elongated and and usually found towards the base of the cells. They form the lining of the stomach and intestines. They secrete mucus to keep the surface smooth. Ciliated Columnar Epithelium are simple columnar epithelial cells but they have fine, hair like cilia on their free surfaces.
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.
LAB THREE: Body Tissues and the Integumentary System Describe the characteristics of epithelial tissue. (5 points) Epithelial tissue is a sheet of cells which covers a body surface or even lines a body cavity. Covering and lining epithelium forms the outer layer of the skin, dips into and lines the open cavities of the cardiovascular, digestive and respiratory systems, and also covers the walls and organs of the closed ventral body cavity. Glandular epithelium fashions the glands of the body. Special characteristics of the epithelial tissue layer are that these types of tissues are composed almost entirely of close packed cells.
Understand the need for tissue viability risk assessment. 1.1…Describe the anatomy and physiology of healthy skin The skin is an outside covering for the human body. It is an organ just like the heart, lung and liver. It provides layer of protection and plays a vital role in maintaining body temperature and by making you aware of external stimuli through the sense of touch. The skin has two layers, the epidermis and the dermis, although not part of the skin, the hypodermis lies beneath the dermis.
Besides providing protection to the body the skin has a host of other functions to be performed like regulating body temperature, immune protection, sensations of touch, heat, cold, and pain through the sensory nerve endings, communicating with external openings of numerous other body systems like digestive system, urogenital system, and respiratory system via mucous membranes.The skin is primarily composed of three layers. The skin, which appears to be so thin, is still itself divided into epidermis, dermis, and subcutaneous layer or hypodermis. Each layer has it own function and own importance in maintaining the integrity of skin and thereby the whole body structure. Pressure sores or decubitus ulcers are the result of a constant deficiency of blood to the tissues over a bony area such as a heel which may have been in contact with a bed or a splint over an extended period of time. The surface of the skin can ulcerate which may become infected.
I know I have 3 layers of skin on my body, the Epidermis layer, the Dermis layer, and the Hypodermis layer; which worked together to keep my body cool and isolated. However, when your body gets hot, the structures in the dermis layer expand quickly to keep your body cool. Blood vessels will expand, increasing the flow of cool blood flowing through the skin. Sweat
The skin provides a physical barrier to keep out foreign materials and prevent the body from drying out, while providing protection and a cushion to the body’s organs. The purpose of this research is to identify the different layers of the skin, characteristics of the skin, including its weight, surface and size. The information gathered will also explain the functions of the integumentary system, structure of the skin and the different types of skin lesions and then provide examples of diseases and disorders. The integumentary system is an important and vital function to the body protecting the surface and acting as an important means of survival. APA Style Sheet 3 The Integumentary System The integumentary system is an alternative name for the skin.
The lymph vessels collect fluid, called lymph from the body tissues and return it to the blood, maintaining the fluid balance within the body. Lymph filters through the lymph nodes, which are packed with white blood cells known as lymphocytes. These are produced in the bone marrow, spleen and thymus, and they help to protect the body against infections. Spleen: This is the largest lymphatic organ. It is located on the left side of the body just above the kidney.
Besides oroviding protection to the body, the skin also helps regulate body temperature, helps your immune system, provides sensations of touch, heat, cold and pain throught the sensory nerve endings. The skin is primarily composed of three layers, the epidermis, the dermis and the subcutanious layer/the hyppodermis. Each layernhas its own function and its own role in maintaining the skin integrity. Pressure sores are the result of a constant deficiency of blood flow to the skin tissue. This is more common over a bony area such as a heel, which may have been in contact with a surface for an extended period of time.
! The human body is an extremely unique organism, made up of many organ systems that work together to maintain life. The skin, hair, nails, sweat and oil glands of the body all make up a complex set of organs which form the Integumentary system. (Marieb, E., & Hoehn, K. (2013) pg 150) ! The skin is our bodies barrier or protection from the outside world.
