Integumentary System The integumentary system is made up of the skin, hair, and nails. This system protects the body from the outside world by acting like a barrier. This system also retains body fluids, protects against disease, eliminates waste products, and regulates body temperature.

Skin The skin is one of our largest organs. The layers of skin are capable of healing themselves no matter how many tears and rips it gets. The skin has sensory receptors that monitor the external environment and it has mechanisms that can get rid of body waste. The skin is composed of two layers; the epidermis and the dermis.

Epidermis The epidermis the outer layer of the skin and it is made up of many layers of flattened epithelial cells. The top layer …show more content…
The only reason why you can sense many kinds of conditions and signals from the environments is because of sensory neurons. Blood vessels helps regulate body temperature, hair follicles pull hair upright when you’re cold or afraid, and glands produce sweat which helps soften your skin. Below the dermis lays fat cells which act as energy reserves.

Glands There are two types of exocrine glands; the sweat glands and the oil glands. The exocrine glands release secretions through ducts. The sweat glands are where the excess water, salts, and urea release through. The body temperature regulates because of the release of the excess water. When our body temperature rises, we sweat which evaporates and cools the skin. Oil glands are found in large numbers on the face and scalp. The oil glands secrete a fatty substance called sebum and is produced based on hormones. Sebum prevents excess water loss and softens the skin and hair. It can also be kind of poisonous towards some bacteria. During teenage years, high levels of sex hormones increase the activity of the oil glands and if the ducts get clogged, the skin disorder acne can

Integumentary System Research Paper

...The integumentary system is similar to an organ system that deals with the hair, skin, nails and exocrine glands. The main part of the integumentary system is the skin. Believe it or not, the skin is the thickest layer on your body. The other parts of this particular system such as hair and nails are found in the epidermis, dermis and subcutaneous. The integumentary system is all about protection.” (Rader) The integumentary system prevents your body from diseases such as acne, eczema and skin cancer. It provides a barrier to block different viruses and bacteria. Some risk may include becoming dehydrated and your body becoming over heated. Another risk is that the skin may experience harmful ultraviolet radiation and un-guard the skin against...

Seven Organizational Approaches Paper

...Carla Paula Tantay May 24, 2015 HCA/220 Seven Organizational Approaches Paper Instructor: Terrasha Rachels There are 7 organizational approaches to studying the human body. The seven organizational approaches consist of planes and directions, body cavities, quadrants and regions, anatomy and physiology, microscopic and macroscopic, body systems and medical specialties. The body planes and body direction is the division of the body in to sections from front to back, right and left, and top and bottom. These sections are called the mid sagittal plane, the coronal plane, and the transverse plane. There are two main cavities; “Dorsal and ventral body cavities”. Based on Bite Anti Body Research, Some anatomical references do not recognize the dorsal body cavity but we will use it in this example because it is use by some professionals and colleges. Dorsal body cavity protects organs in our nervous system and dorsal body cavity has 2 divisions which is cranial which works around the brains and spinal which works around the spinal cord. With Ventral the superior division is called the thoracic cavity. The thoracic cavity is surrounded by the ribs and muscles in the chest. It’s further subdivided into lateral pleural cavities (each pleural cavity envelopes a lung) and the mediastinum. Within The pericardial cavity lies within the mediastinum. Quadrants are divides our bodies into regions for diagnostic and descriptive purposes. The quadrants are defined by drawing an imaginary...

Integumentary System Analysis

...The Integumentary System (skin) covers the whole body. It is water proof and is used for a mechanical barrier. The skin has many facets and functions. Therefore the functions are protection, temperature maintenance, and storage of nutrients, sensory receptors, excretion, and secretion. This entails the 3 main layers that are epidermis, dermis, and hypodermis or subcutaneous (superficial fascia) to regulate all functions inside the human body. There are a few ways the functions and facets turn the abnormal conditions to normal conditions in the human body by maintaining homeostasis. The facets use the best in beauty; which includes the hair and nails. The other name for nails is the accessory structures of the skin. Therefore it is what makes...

Multiple Myeloma

...involved in the formation or storage of blood, the hematologic system allows the human body to maintain adequate oxygenation and tissue perfusion (Ignatavicius & Workman, 2010, p. 876). Because every cell, tissue, organ, and system is dependent on blood circulation for survival, hematologic problems involving impaired production, impaired function, or abnormal destruction of blood cells are likely to have wide-reaching effects on the patient's health and wellness (Ignatavicius & Workman, 2010, p. 876). This is especially clear when examining cancers of the hematologic system, including multiple myeloma. A cancer of certain white blood cells in the bone marrow known as plasma cells, “myeloma” refers to a tumor of the bone marrow, and “multiple” refers to more than one area of the bone marrow being affected (Mangan, 2006, p. 64hn1). Because the disease is incurable, and because only 30 percent of patients survive longer than five years after diagnosis, living with multiple myeloma can be difficult for patients and their families (Mangan, 2006, p. 64hn1). As health care providers on the front lines of patient care, nurses must be aware of the multi-system manifestations of multiple myeloma, be able to make the assessments needed to identify and prevent complications related to the disease and its treatment regimen, and be ready to provide patients and their families with knowledge and support. In this paper, the author will first provide a full description of multiple...

...Clinical Notes The Visible Human Project p. 7 Homeostasis and Disease p. 13 An Introduction to Studying the Human Body This textbook will serve as an introduction to the inner workings of your body, providing information about both its structure and its function. Many of the students who use this book are preparing for careers in health-related fields—but regardless of your career choice, you will find the information within these pages relevant to your future. You do, after all, live in a human body! Being human, you most likely have a seemingly insatiable curiosity—and few subjects arouse so much curiosity as our own bodies. The study of anatomy and physiology will provide answers to many questions regarding the functioning of your body in both health and disease. Although we will be focusing on the human body, the principles we will learn apply to other living things as well. Our world contains an enormous diversity of living organisms that vary widely in appearance and lifestyle. One aim of biology—the science of life—is to discover the unity and the patterns that underlie this diversity, and thereby shed light on what we have in common with other living things. Animals can be classified according to their shared characteristics, and birds, fish, and humans are members of a group called the vertebrates, characterized by a segmented vertebral column. The shared characteristics and organizational patterns provide useful clues about how these animals have evolved over time...

...ork2012 - 2013 Catalog A Message from the President “Sullivan University is truly a unique and student success focused institution.” I have shared that statement with numerous groups and it simply summarizes my basic philosophy of what Sullivan is all about. When I say that Sullivan is “student success focused,” I feel as President that I owe a definition of this statement to all who are considering Sullivan University. First, Sullivan is unique among institutions of higher education with its innovative, career-first curriculum. You can earn a career diploma or certificate in a year or less and then accept employment while still being able to complete your associate, bachelor’s, master’s or doctoral degree by attending during the day, evenings, weekends, or online. Business and industry do not expand or hire new employees only in May or June each year. Yet most institutions of higher education operate on a nine-month school year with almost everyone graduating in May. We remained focused on your success and education, and continue to offer our students the opportunity to begin classes or to graduate four times a year with our flexible, year-round full-time schedule of classes. If you really want to attend a school where your needs (your real needs) come first, consider Sullivan University. I believe we can help you exceed your expectations. Since words cannot fully describe the atmosphere at Sullivan University, please accept my personal invitation to visit and experience...
