Dermis is mainly connective tissue, is deep to the epidermis, and is vascular * The skin contains collagen (for strength) and elastic (for stretch) fibers. * The skin is thicker on the posterior than the anterior parts of the body; thicker on lateral parts of limbs than medial parts. —Subcutaneous layer (or hypodermis) is deep to dermis, but is not part of skin. It is mainly adipose tissue B. Layers of epidermis (from deepest to superficial) 1. Stratum Basale (= base) a. has stem cells that continuously divide by mitosis
Enzymes are proteins that cause chemical reactions to occur. In cases of lactose intolerance, the body does not produce enough of the lactase enzyme so lactose stays in the digestive system, where it is fermented by bacteria (in the same way that yeast is fermented to produce beer). It’s this fermentation process that causes the symptoms associated with lactose intolerance. Levels of lactase often fall as people grow older and some health conditions can also reduce the production of lactase. What are the symptoms?
Essay shows the importance of bones in human body and their main role, tasks they accomplish every day. Skeletal function Six functions of the skeleton: Support: Provides structural support for the entire body Protection: Surrounds soft tissue- ex. ribs and sternum protect the heart and lungs, - skull protects the brain Movement: Skeletal muscle is attached to bone so it pulls on the bone when it contracts Mineral homeostasis: Stores calcium and phosphorus--minerals are released into the blood when needed Blood cell production: Red bone marrow produces red blood cells, white blood cells and other blood elements. Storage: Storage of minerals and lipids (fats)-yellow marrow stores fat-(found in long bones) Bone. Definition: Bones are rigid organs that constitute part of the endoskeleton of vertebrates.
It is produced by the sweat glands and pours out onto the surface of the skin, the water then evapoarates which removes heat from the skin therefore cooling the skin down. Whenever your body feels a change on the outside, it must account for and adjust functions inside the body in order to maintain its normal state. When you exercise, your muscle tissues demand more oxygen. The body responds to this increased demand by increasing blood flow, which creates higher blood pressure. In order to get more oxygen into your body and into your blood to flow to those muscles, you have to take in more oxygen through breathing.
Thermoregulation is supported through sweating and regulation of blood flow through the skin and synthesis of Vitamin D occurs. As the body gets older, poor nutrition or disability occurs, the skin is under pressure of getting damage through pressure sores. Factors such as shearing, friction and compression are the major cause of a person to have developed a pressure sore. 1.2… Describe the changes that occur when damage caused by pressure develops. Discoloration of intact skin not affected by light finger pressure (non blanching erythema) this may be difficult to identify in darkly pigmented skin.
APA Style Sheet 3 The Integumentary System The integumentary system is an alternative name for the skin. The integumentary system is the body’s largest organ and makes up for 15% of the body’s weight. The integumentary system not only includes skin but skin derivatives such as hair, nails and glands. The hair functions as protection and sensing light touch. The hair is made up dead, keratinized cell bonded together by protein.
Right now I am located in the right femoral vein, which is located in the upper thigh and pelvic region of the body. It is also one of the largest veins in the venous system. The femoral vein’s purpose is to take all the blood in the lower region of the body and deliver it to the heart via the iliac vein. Today’s
Sebum is secreted into areas like the hair follicles or the pores on the skin surface. The sebaceous gland secretes sebum in order to soften and lubricate the hair and skin and also prevent the hair from becoming brittle and it also assist with slowing down the water loss from the skin when external humidity is low. It also has a bactericidal action. In order for the skin to secrete sebum it must stimulated by certain hormones especially
Unit 4222-229 Undertake agreed pressure area care (HSC2024) Karen Yardley Outcome 1 understand the anatomy and physiology of the skin in relation to pressure area care 1.1 describe the anatomy and physiology of the skin in relation to skin breakdown and the development of pressure sores. The skin is the largest organ of the body, covering and protecting the entire surface of the body. The total surface area of the skin is around 3000sq inches depending on age, height and body size. As well as the nails, hair, sweat glands and the sebaceous glands, the skin forms the integumentary system. 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.
It is important to consume of your daily protein because your body begins to take away from your carbohydrates and lipids to make up for your lost protein, which can result in drowsiness or weight loss/gain, and it can also cause illness. Protein, carbohydrates, and lipids are referred to as macronutrients. Macronutrients are substances needed for growth and metabolism, and they also provide energy (“Macronutrients”, 2004). When we consume too much or too little of a macronutrient we can become more susceptible to illness or disease. For example, two diseases that develop from too little protein are Kwashiorkor and Marasmus, and too diseases that develop because of too much carbohydrates and lipids are Diabetes and Cardiovascular Disease.
