A brief introduction to the circulatory system and Integumentary System

Integumentary System

The Integumentary System is composed of various organs that protect the body against injury or damage. It's about the skin and its appendages such as nails, hair and dandruff. This system has a variety of functions that regulate primarily to protect and cushion the deeper tissue, the temperature and excrete waste.

In humans, this system gives an additional vitamin D mixture. It is the largest organ system. It informs, protects, separates anddistinguishes the animal with regard to its surroundings. There are many possible diseases and injuries of human rights Integumentary system. Possible diseases and injuries include blisters, sunburn, rashes, infections, skin cancer, athlete's foot, acne and albinism.

Features

The Integumentary system has many roles in homeostasis. The whole body systems work interdependently on the internal requirements for the body to maintain normal and healthy. The skin hasimportant tasks of the protection of the body. In addition, the skin acts as the organ, the first protection against temperature changes, infections and other challenges to homeostasis.

The primary functions include the storage excrete vitamin D, water and fat content and the production of vitamin D by irradiation with ultraviolet light using waste products through sweating. The functions include the protection of the internal organs and tissues of our body and the protection of the bodyDehydration.

Layers

The top layer of skin is of the epithelial cells and their main function is for defense. Structurally it is from "keratinized stratified squamous Elium" which consists of four different types of cells, such as from melanocytes, keratinocytes, Langerhans cells and Merkel cells.

Most of the epidermis, is that keratinocytes produce keratin. The keratin is a large protein, which is to protect AIDS. Many dead keratinocytes and rub daily creates a new epidermisfor about 25-45 days. The melanocytes produce melanin, a substance which the 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 is composed mainly of fat tissue and areolar tissue. Its purposes include physiological aid in theAnchoring of the skin, insulation and energy storage. The pillow subdermis underlying body for additional protection against trauma.

Bloodstream

Circulatory system is an organ that waste, nutrients and gases from the cells and moves in to help combat viruses or diseases. It also helps to stabilize pH and body temperature in order to maintain homeostasis. The system can be seen as a blood distribution network, but many people consider this system aswith the participation of the lymphatic system, the lymphatic and cardiovascular system, which distributes the blood spread.

The main elements 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 that delivers oxygen plasma, white blood cells, red blood cells and platelets. The circulatory system also includes pulmonary circulation, a loop through the lungs where the blood isoxygenated. The digestive system also uses this system to deliver nutrients, the system must keep the heart pumping.

The two types of fluids move through the entire circulatory system and heart are the lymph. The lymph nodes, lymph vessels and lymph nodes form the lymphatic system. The heart, blood vessels and blood make up the cardiovascular system. The lymphatic system and cardiovascular system are cooperatively the circulatory system.
