The tissue are a group of cells that have the same structure and perform different functions. Tissue comes from the Old French word verb, which means, ” to weave “. There are four types of this in animals, including connective tissue. There are three types of muscle, nerve, and epithelial tissue and plants: vascular, terrestrial, and epidermis. Tissues make up the brain and heart in the body۔
Types of Tissues
Animal Tissues
Connective Tissues
Connective tissue connects or separates groups of other tissues. It exists between all other tissues and organs in the body. Connective tissue is composed of cells and abrasive material, which is a gel surrounding the cells. In addition to lymph and blood, most connective tissues also contain fibers, which are long, narrow proteins. Fiber can be collagen, which binds bones and tissues together. Elastic can move organs like lungs; or mesh, provide physical support for cells. Connective tissue also allows oxygen to diffuse from blood vessels to cells.
Muscle Tissues
Muscle tissue encompasses all the muscles of the body, and the specialized nature of the tissue is the cause of muscle contraction. There are three types of muscle tissue: skeletal muscle, heart muscle, and smooth muscle. Skeletal muscles anchor to the bones and move the body. The heart muscle is found in the heart and shrinks to draw blood. Smooth muscle is found in the intestines and helps to move food in the digestive system. It is also found in other organs (such as blood vessels, uterus, and bladder). Skeletal muscle and myocardial striae; this means that they have sarcomas (muscle tissue units) arranged in a similar pattern. There is no sarcoma in the smooth muscle.
Nervous Tissues
Nerve tissues are found in the brain, spinal cord, and peripheral nerves. They are all parts of the nervous system. It is made up of neurons and glacial. Neurons are nerve cells, and glacial is the cell that helps in the transmission of nerve impulses. There are four types of nervous tissue: gray matter and white matter in the brain, and nerve and ganglia in the peripheral nervous system. The main difference between gray matter and white matter is that the axons of neurons in gray matter are unilateral, while the white matter is metabolized. Myelitis is a white fatty substance that can insulate neurons and is essential for a nervous system’s function.
Epithelial Tissues
The epithelial tissue or epithelium covers the surface of the organs including the skin, trachea, reproductive tract, and internal walls of the digestive system. It creates a barrier that helps protect organs and has the effect of absorbing water and nutrients, eliminating waste, and affecting enzymes or hormones. All glands in the human body are made up of ingrown epithelial cells. Some common epithelial tissue diseases are skin diseases, such as eczema and psoriasis, both of which cause skin rashes. When cancer develops from epithelial tissue, it is called cancer. Epithelial cells in the airways are also associated with asthma, which is characteristic of airway inflammation for shortness of breath.
Plant Tissues
Vascular Tissues
Vascular tissue in plants carries substances to different parts of plants. There are two types of vascular tissue xylem and phloem. Xylem transfers water and some soluble nutrients, and phloem transfers the organic compounds used by plants to food, especially sucrose. The blood vessel tissue is long and thin, forms a cylindrical shape, and nutrients are transported like a pipe. Vascular tissue also includes two types of meristems, which are tissues that contain afferent cells used in plant growth. The coefficients with vascular tissue are cork cambium and vascular cambium. These properties are related to the development of plant vascular tissues.
Ground Tissues
Ground tissue contains all cells that are not blood vessels or dermis (not related to the epidermis; see below). There are three types of ground tissue: parenchyma, renal pelvis, and sclerosis. Parenchyma cells make “filler” tissue in plants and perform many functions such as photosynthesis, starch, fat, oil, protein, and water storage and repair of damaged tissue. Colon tissue is composed of long cells with irregular wall thickness, which provides structural support for plants. Plants growing in ventilated areas have thick walls of tissue. Saleroom also supports tissue but is made up of dead cells. There are two types of sclerosis: fibrous and sclerotic. Fibers are elongated cells, while sclerotic cells are star-shaped with a thick cell wall. Scleral fibers make fabrics such as hemp and linen.
Epidermal Tissues
The epidermis is made up of a layer of cells, covering the roots, stems, leaves, and flowers of the plants. (The epidermis is also synonymous with skin in human anatomy.) It protects plants from water loss, regulates the exchange of carbon dioxide and oxygen, and absorbs water and nutrients from the soil from the roots. . The epidermis present on the stems and leaves of plants has a hole called stomata, through which carbon dioxide, water vapor and oxygen are circulated. The epidermal cells themselves are covered by the plant epidermis, which consists mainly of keratin, a waxy substance that prevents water loss. Plants in deserts and other arid areas often have thick skins to help preserve water.
Function of Tissue
Different body systems perform different functions. For example, your digestive system is responsible for food intake and processing, while your respiratory system (working with the circulatory system) is responsible for absorbing oxygen and removing carbon dioxide. Muscle and skeletal systems are essential for exercise. The reproductive system processes reproduction, the excretory system gets rid of metabolic waste.
Due to their professionalism, these various systems are interdependent. The cells that make up the digestive system, the muscular system, the skeletal system, the reproductive system, and the excretory system require oxygen in the respiratory system. All systems of the body work together to maintain the normal functioning of the organism.
