Skin

Skin

The skin is a living functioning organ that plays a key role in maintaining the body's homeostasis



The skin protect the human body but it also allows humans to connect with the outside world



The skin is composed of two main layers the epidermis and the dermis and contains accessory organs such as sweat glands and hair follicles



The skin is a dynamic organ that functions in protection temperature regulation sensation excretion and absorption in the human body



Burn damage to skin can impact numerous body functions and body systems in the human body




Both the body's ability to sense pain and to suppress pain and help protect the human body from injury and death

Skin Vocabulary

Collagen


an insoluble fiber is protein of vertebrates that is the chef constituent of the fibrils of connective tissue is in skin and tendons and of the organic substance of bones



Connective tissue


Animal tissue that functions mainly to bind and support other tissues having a sparse population of cells scattered through an extracellular Matrix



Dermis


The sensitive vascular inner mesodermic layer of skin



Elastin


A protein that is similar to call again and as the chief constituent of elastic fibers



Endorphin


A hormone produced in the brain and anterior pituitary that inhibits pain perception



Epidermis


The outer non-sensitive and non vascular layer of the skin of a vertebrate that overlies the dermis




A membranous cellular tissue that covers a free surface or lines a tube or cavity of an animal body and service especially to enclose and protect the other parts of the body to produce secretions and excretions and to function in assimulation



Exocrine gland


Epithelium A membranous cellular tissue that covers a free surface or lines a tube or cavity of an animal body and service especially to enclose and protect the other parts of the body to produce secretions and excretions and to function in assimulationExocrine gland A gland is a sweat gland and salivary Glendora kid need that releases a secretion external to or at the surface of an organ by means of a canal or ductFirst degree burn A mild burn characterized by feet pain and reddening of the burn surface but not exhibiting blistering or jarring of tissuesKeratin


A gland is a sweat gland and salivary Glendora kid need that releases a secretion external to or at the surface of an organ by means of a canal or duct



First degree burn


A mild burn characterized by feet pain and reddening of the burn surface but not exhibiting blistering or jarring of tissues


Any of various sulfur-containing fibrous proteins that form the chemical basis of epidermal tissues as hair and nails and are typically not digested by enzymes of the gastrointestinal tract



Melanin


Any of various black dark brown reddish brown or yellow pigments of animal or plant structure (as in skin and hair)



Pain


Basic bodily sensation that is induced by a noxious stimulus is received by naked nerve endings is characterized by physical discomfort (as pricking dropping are aching) and typically into evasive action



Sebaceous gland


Any of the small sacculated glands lost in the substance of the dermis usually opening into the hair follicles and secreting an oily or greasy material composed and great part of that which softens and lubricates the hair and skin



Second-degree burn


Auburn marked by pain blistering and superficial destruction of dermis with edema and no hyperemia of the tissues beneath the burn



Third-degree burn


Severe burn characterized by destruction of the skin to the depth of the dermis and possibly into underlying tissue loss of fluid and sometimes shock

Burns

Burns

Burns

First degree burns may be treated with skin care products like aloe vera cream or antibiotic ointment and pain medication such as acetaminophen Tylenol



Second-degree burns may be treated with an antibiotic cream or other creams or ointments prescribed by a doctor



The treatment of third-degree Burns may require the process of skin grafting or the use of synthetic skin severe burns covering large parts of the body may need more intensive treatment such as IV antibiotics to prevent infection in IV fluids to replace fluids lost when skin was burned

Bone

Bone Vocabulary

Bone marrow


A soft highly vascular modified connective tissue that occupies the cavities and cancel is part of most bones and occurs in two forms yellow and red



Bone remodeling


The continuous turnover of bone matrix and mineral that involves first an increase in resorption and osteoclast activity and later reactive bone formation by osteoblast activity



Calcitonin


A poly peptide hormone especially from the thyroid gland the fens to lower the level of calcium in the blood plasma



Callus


A growth of new bone tissue in and around a fractured area ultimately replaced by mature bone



Cartilage


Usually a translucent somewhat elastic tissue that composes most of the skeleton of vertebrates embryos and except for a small number of structures as some joints respiratory passages and the external ear is replaced by bone during ossification and the higher vertebrates



Compact bone


Bone tissue that contains few spaces between osteons forms the external portion of all bones and the bulk of the diaphysis shaft of long bones



Diaphysis


The shaft of a long bone



Epiphysis


The end of a long bone usually larger in diameter than the shaft



Fracture


The breaking of hard tissue (as bone)



Osteoblast


A bone forming cell



Osteoclast


Any of the large multinucleated cells closely associated with areas of bone resorption as in a fracture that is healing




Osteocyte Cell that is characteristic of adult bone is isolated in a lacuna of the bone substance


Cell that is characteristic of adult bone is isolated in a lacuna of the bone substance



Parathyroid hormone


A hormone of the parathyroid gland that regulates the metabolism of calcium and phosphorus in the body



Spongy (cancellous) bone


Bone tissue that consists of an irregular latticework of thin plates of bone called trabeculae found inside short, flat, and irregular bones and in the epiphysis of a long bone

Different Types of Breaks

4 Stages of Bone Healing

Step 1 Hematoma Formation


Blood vessels that are rupture during the breaks well to form a mass called hematoma this nass forms between the broken bones



Step 2 Fibrocartilage Callus Formation


New capillaries begin to form into the clotted blood in the damaged area. connective tissue cells form a mass of repair tissue called a fibrocartilage callus. this callous contains some cartlidge some bone and collagen fibers and the combined mass closes the gap between the broken bones



Step 3 Bony Callus Formation


The fibrocartilage callus is gradually replaced by one made of spongy bone this new mass is referred to as the Bony callus osteoclast and osteoblast moved to the area and multiply



Step 4 Bone Remodeling


Over the weeks and months to come the callus is remodeled with the help of osteoclast and osteoblast the shape of the bones will gradually return to normal and there will eventually be little evidence of the fracture

Calcium Feedback Loop

Lymph and Blood Cells

Lymphatic System

Consist of organs ducts and nodes and transports a watery clear fluid called lymph



Lymph vessels interact with the circulatory system to drain the fluid from your cells and tissues



Lymph also distributes immune cells around the body



anything that is foreign to the body and get your immune system fired up is referred to as an antigen. antibody is are proteins and blood and lymph that seek out and bind to specific antigens. these specialized proteins are one of the primary defenders and your body's army of immunity your body contains tons of antibodies is designed to target and destroy specific antigen

Blood Transfusions
