Integumentary
The integumentary system is composed of various organs that protect the body against injury or damage. It's about the skin and its annexes, such as nails, hair and dandruff. This system has a variety of functions, primarily to protect and an attenuation of the deeper layers of tissue to regulate the temperature and eliminate waste.
In humans, this system offers an additional vitamin D compound. It is the largest organ of the system. It informs, protects, separates anddistinguishes the animal with regard to its surroundings. There are many possible diseases and injuries of the human integumentary system. Possible diseases and injuries are blisters, sunburn, skin rashes, infections, skin cancer, athlete's foot, albinism and acne.
Features
The integumentary system has many roles in homeostasis. The whole body depends on systems operating to maintain the internal conditions for the body to normal and healthy. The skin hasimportant tasks of the protection of the body. In addition, the skin appears as the first protecting the body against temperature changes, infections and other challenges to homeostasis.
The primary functions include the storage of vitamin D, water and fat content and the production of vitamin D by irradiation with ultraviolet light using separate waste by sweating. The functions include protection of internal organs and tissues of the body and the protection of the bodyDehydration.
Layers
The top layer of skin is composed of epithelial cells and their main task is to made for the defense. Structurally, it is formed of keratinized stratified squamous elium ", which consists of 4 different types of cells such as melanocytes, keratinocytes, Langerhans cells and Merkel cells.
Most of the epidermis keratinocytes that produce keratin. The keratin is a large protein that aids in the protection. Many dead keratinocytes daily and rub off a new epidermis formedfor about 25 to 45 days. The melanocytes produced melanin, a substance that gives skin its color.
The epidermis contains several types of cells such as squamous cell and basal cells. The cells squqamous flaking cells on the surface of the skin and the basal cells are round cells.
The subcommittee dermis is a layer of tissue below the dermis. The subdermis consists mainly of fat and areolar tissue. The physiological purposes include aiding in theAnchoring of the skin, insulation and storage of energy. The subdermis the underlying body pillow for added protection against injury.
Circulatory System
Circulatory system is an organ that waste, nutrients and gases and sets out the cells that help to fight there any virus or illness. It also helps to maintain pH stabilization and body temperature in order to maintain the homeostasis. The system can be regarded as a blood distribution network, but more persons to make this system asParticipation of the lymphatic system, the lymphatic and cardiovascular system, which distributes the blood spread.
The main components of the human circulatory system are the blood vessels, the heart and the blood. The cycle includes the systemic circulation, a loop for the rest of the body, and the plasma containing oxygen, white blood cells, red blood cells and platelets. The circulatory system also includes the pulmonary circulation, a loop through the lungs where the blood isOxygen. The digestive system works well with this system to deliver nutrients to the system needed to keep the heart pumps.
The two types of fluids moving throughout the circulatory system are the lymph and heart. The lymph nodes, lymph vessels and lymph nodes form the lymphatic system. The heart, blood vessels and the shape of the cardiovascular system. The lymphatic system and cardiovascular system cooperatively form the circulatory system.
