The integumentary system is composed of the following parts:Skin.Skin appendages. Hairs. Nails. Sweat glands. Sebaceous glands.Subcutaneous tissue and deep fascia.Mucocutaneous junctions.Breasts.
What are the 3 primary functions of the integumentary system?
The skin consists of two layers: the epidermis and the dermis. Beneath the dermis lies the hypodermis or subcutaneous fatty tissue. The skin has three main functions: protection, regulation and sensation.
What are the 3 main jobs of the integumentary system?
It protects our body, it keeps microbes and other harmful materials out in the body, it also keeps body fluids in and helps control body temperature.
What are the 3 integumentary system?
The integumentary system is an organ system consisting of the skin, hair, nails, and exocrine glands.
What are 4 Interesting facts about the integumentary system?
A single square inch of skin has about 19 million cells and up to 300 sweat glands. Your skin is its thickest on your feet (1.4mm) and thinnest on your eyelids (0.2mm). The skin renews itself every 28 days. Your skin constantly sheds dead cells, about 30,000 to 40,000 cells every minute!
What does the integumentary system protect?
The skin and its derivatives (hair, nails, sweat and oil glands) make up the integumentary system. One of the main functions of the skin is protection. It protects the body from external factors such as bacteria, chemicals, and temperature.
What are the 6 parts of the integumentary system?
The integumentary system is the largest organ of the body that forms a physical barrier between the external environment and the internal environment that it serves to protect and maintain. The integumentary system includes the epidermis, dermis, hypodermis, associated glands, hair, and nails.
What structures make up the integumentary system Chapter 6?
The integumentary system is an organ system consisting of the skin, hair, nails, and exocrine glands. FUN FACT: The skin is the largest organ of the human body!
What are the 3 primary functions of the integumentary system?
The skin consists of two layers: the epidermis and the dermis. Beneath the dermis lies the hypodermis or subcutaneous fatty tissue. The skin has three main functions: protection, regulation and sensation.
What are the functions of the integumentary system quizlet?
What are the functions of the integumentary system? Its main function is to act as a barrier to protect the body from the outside world. It also functions to retain body fluids, protect against disease, eliminate waste products, and regulate body temperature.
How does the integumentary system regulate body temperature?
The integumentary system helps regulate body temperature through its tight association with the sympathetic nervous system , the division of the nervous system involved in our fight-or-flight responses. The sympathetic nervous system is continuously monitoring body temperature and initiating appropriate motor responses. Recall that sweat glands, accessory structures to the skin, secrete water, salt, and other substances to cool the body when it becomes warm. Even when the body does not appear to be noticeably sweating, approximately 500 mL of sweat (insensible perspiration) are secreted a day. If the body becomes excessively warm due to high temperatures, vigorous activity ( Figure 5.16 ac ), or a combination of the two, sweat glands will be stimulated by the sympathetic nervous system to produce large amounts of sweat, as much as 0.7 to 1.5 L per hour for an active person. When the sweat evaporates from the skin surface, the body is cooled as body heat is dissipated.
What are the functions of skin and accessory structures?
The skin and accessory structures perform a variety of essential functions, such as protecting the body from invasion by microorganisms, chemicals, and other environmental factors; preventing dehydration; acting as a sensory organ; modulating body temperature and electrolyte balance; and synthesizing vitamin D.
What organs are most sensitive to touch?
These receptors are more concentrated on the tips of the fingers, which are most sensitive to touch, especially the Meissner corpuscle (tactile corpuscle) ( Figure 5.15 ), which responds to light touch, and the Pacinian corpuscle (lamellated corpuscle), which responds to vibration. Merkel cells, seen scattered in the stratum basale, are also touch receptors. In addition to these specialized receptors, there are sensory nerves connected to each hair follicle, pain and temperature receptors scattered throughout the skin, and motor nerves innervate the arrector pili muscles and glands. This rich innervation helps us sense our environment and react accordingly.
What is the purpose of skin in armor?
The skin, in its own way, functions as a form of armor—body armor. It provides a barrier between your vital, life-sustaining organs and the influence of outside elements that could potentially damage them.
What is the skin's role in protecting the body from the elements?
It acts as a protective barrier against water loss, due to the presence of layers of keratin and glycolipids in the stratum corneum.
Why do ants crawl on skin?
The fact that you can feel an ant crawling on your skin, allowing you to flick it off before it bites, is because the skin, and especially the hairs projecting from hair follicles in the skin, can sense changes in the environment. The hair root plexus surrounding the base of the hair follicle senses a disturbance, and then transmits the information to the central nervous system (brain and spinal cord), which can then respond by activating the skeletal muscles of your eyes to see the ant and the skeletal muscles of the body to act against the ant.
Answer
The integumentary system consists of the skin, hair, nails, glands, and nerves. Its main function is to act as a barrier to protect the body from the outside world. It also functions to retain body fluids, protect against disease, eliminate waste products, and regulate body temperature.
