It is the general supporting or packing tissue of the body. The type is loosely woven & has a gelatinous (protein containing glue like substance) substance between cells. Fatty tissue or Adipose – this type is made up of globules of fat that are found in thin membranous envelopes. It is found under the skin around the kidneys, bone marrow & the heart. It can provide protection, insulation & reserve food.
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.
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.
Skin and the Integumentary System A. Skin is composed of 2 main layers 1. Epidermis is made of keratinized stratified squamous epithelial tissue, is superficial to the dermis, and is avascular. 2. Dermis is mainly connective tissue, is deep to the epidermis, and is vascular * The skin contains collagen (for strength) and elastic (for stretch) fibers.
MARROW CAVITY- ENDOSTEUM- n a thin layer of connective tissue that lines the walls of the bone marrow cavities and haversian canals of compact bone and covers the trabeculae of cancellous bone. It has
Priscilla Sims 1. Compare and contrast the functions of each tissue type. Why do some areas of our body have stratified squamous epithelium and other areas have simple squamous epithelium? There are four basic tissue types in the human body: epithelial, connective, muscle and neural. The epithelial tissue covers the body surfaces and lines the cavities and tubular structures and serves essentials functions.
Which muscle type has the most elaborate connected tissue wrapping? Skeletal muscle 3. What is the striated mean relative to muscle cells? Stripped or having bands striated 4. How do the movements promoted from skeletal muscle smooth muscle?
Multiple organ systems make the organism. You are an organism. You have nervous systems, digestive systems, cardiovascular systems etc. Your digestive system is made of several organs such as your tongues, eyes, esophagus, stomach, small intestine, large intestine, etc. To be a living things need to breath, need shelter, water, food, air, roomy environment, etc.
Fructose is converted into fat that gets stored in your liver and other tissues as body fat. Part of what makes fructose so bad for your health is that it is metabolized to fat in your body far more rapidly than any other sugar.
Vitamins can be broken down into fat and water-soluble, in which fat-soluble (A, D, E, and K) can be stored in fat cells while water-soluble must be constantly replenished as it is being circulated rapidly. Minerals differ from vitamins in that they are inorganic, but still serve to the same definition. Examples include sodium, potassium, and calcium. Micronutrients are found abundantly in foods such as fruits and vegetables, but due to the very nature of micronutrients, many athletes fulfill their daily
