Also is serves as anchors to the skeletal muscles. The bones in the act like a hard shell to protect the internal organs such as the brain, the skull is a hard barrier for most objects to go through. Another function is movement the system acts as attachment point for the skeletal muscles of the body. Joints provide movement for the bones and every skeletal muscle works by pulling two or more bones either closer or further apart from the body. The skeletal system also helps to maintain hematopoiesis in the bones. Which is where red bone marrow produces red and white blood cells in a process known as hematopoiesis. The red marrow is found in the hollow space inside of the bones cavity. Red bone marrow is mostly found in children because when you hit puberty the red bone marrow turns in yellow bone marrow. Last the bones provide storage for many different types of essential substances to facilitate growth and repair of the body. Calcium banks are located in bone which releases calcium into the blood stream when needed to reach other parts of the body. Bone cells also release osteocalcin which is a hormone that helps regulate blood sugar and fat deposition. The yellow bone marrow inside the long hollow leg bones store energy in the form of lipids. The skeleton system does amazing most people wouldn’t even think of and protects are human body
The skeletal system is made up of bones, tendons, cartilages, and ligaments. The bone is a tissue that makes up about eighteen percent of the human body weight (Tortora and Derrickson 183). An infant is born with about 300 to 350 bones but as they grow up some of these bones fuse together. An adult has 206 bones (Zimmermann 2012). The skeletal system has various functions such as support, movement, mineral homeostasis, blood cell production, triglyceride storage, and protection (Tortora and Derrickson 183). The bone continues to grow, remodel and repair itself (Tortora and Derrickson 182). There are some differences between the male and female skeletal system and this difference is mainly due to the role of childbirth (Zimmermann 2012). The skeletal system can be divided into two major groups. These groups are the axial skeleton and appendicular skeleton.
The job of the immune system is to keep “foreign” invaders out of the body, or if one gets in, to seek it out and kill it. These foreign invaders are called pathogens, which are tiny organisms that can cause an infection in the body. Pathogens can be bacteria, parasites, and fungi (http://www.niaid.nih.gov/topics/immuneSystem/pages/whatisimmunesystem.aspx).
The musculoskeletal system was designed to provide the body its form, support, stability and movement. It's made up of 206 bones of the skeleton, muscles, cartilage, tendons, ligaments, joints, and other connective tissue which help support and binds
Lymphocytes travel through the body through blood vessels, or through lymphatic vessels that have a similar structure to veins. Cells and fluids can be exchanged between the blood and the lymphatic system to help the body find microbes. The lymphatic system transports lymph, which contains white blood cells,
A parent’s alcohol addiction has a negative effect on themselves and their child as it results in mental, emotional, and physical abuse within the family. In The Body, Chris Chambers’ father is a raging alcoholic who does not care about anybody. Mr. Chambers will stay at home with Chris and Chris’ siblings and beats them and his wife: “Chris was marked up every two weeks or so, bruises on his cheeks and neck or one eye swelled up” (306). Mr. Chambers does not care about how young or helpless his children or Mrs. Chambers is. Chris and his siblings will be bruised anywhere on their bodies which the public sees but he does not care what people think of him or his children. For there is no respect that he gives to himself or to his children because
In the event of injury certain mast cells in the connective tissues send out histamine molecules. That cause vasodilation, developing redness and heat at the site of infection. The heat helps bump up the cells metabolic rate so that they can repair quickly. While histamine and other chemicals of inflammation increase the permeability of blood vessels. Then triggering capillaries to release protein-rich fluids. Then because of this swelling takes place, the leaked proteins assist the blood in clotting and forming a scab. While the lymphatic system is cleaning the remaining fluid to be filtered to go back into blood. The openness of the capillaries make it easier for phagocytes to escape. They will then come to the site to seize the pathogens and clean up dead cells. Since neutrophils were the first to arrive first they are starting to die out near the end. Interferons are then present and they alert and protect the surrounding cells that have not yet been infected. This then allows antiviral proteins to block viral reproduction. Therefore, when leukocytosis occurs after the virus starts to heal they are then alerted by the capillaries to come. The neutrophils then bind to the capillary walls near site of virus and squeeze through the vessel to start working. Then monocytes turn into macrophages replacing the neutrophils, cleaning up the rest of the

First of all, there are specific mechanisms, cells involved and stimulus for antibody production that need to be delineated. The specific mechanisms are activated in response to a specific pathogens. They are also active against a specific pathogen. Specific mechanisms also prevents reinfection gain immunity. The humoral and cell-mediated immune defense mechanisms induced against an infectious agent are specific in nature, i.e. the specific immune mechanisms act only against the microbe against which the responses were induced and not against other microbes. The stimulus for antibody production is an antigen, which is a substance such as bacteria or other agents that the body recognizes as ‘foreign.’
This paper explores the human skeletal system including its purpose, structure, and the common diseases and disorders that affect it. The human skeleton has a unique design meant to provide structural support and act as a reservoir for minerals in the body. The paper also expounds on the components of the skeletal system such as the axial and appendicular skeletal systems. The axial skeletal system is tasked with supporting the head, neck, and trunk. It is composed of the cranium, vertebral column, the rib cage, and the thoracic cage. The appendicular skeletal system, on the other hand, is composed of the limbs, upper and lower parts of the body like the femur, carpals, tarsals, and humerus. The body’s hardest parts are components of the skeletal
The process of blood coagulation relates to the term haemostasis. Haemostasis is a process of stopping the flow of the blood. When a blood vessel is damaged or injured, the platelets in the blood become attached to macromolecules which are located in the endothelial tissues and form a haemostatic plug. Coagulation consists of platelets and protein. These platelets form the primary layer which creates the haemostatic plug. This process protects the body from infection and disease as the fast-healing motion reduces the risk of pathogens and micro-organisms entering the body through the damaged skin and blood
Blood has three types of cells the white blood cells, red blood cells and the platelets. All these three types of blood have something different job to do. For the white blood cells, they are the once that fight infection. Red blood cells are the once we have more and the once that carry oxygen all over our body. The platelets are blood to clot.
The skeletal system is made up of 206 bones, as well as tendons, ligaments, and cartilage that connects them. The skeletal system has six major functions. The first function is that it supports and provide structure, the second is it facilitates the movement, as the muscles contract and shorten they pull on the bones and move them. The Skeletal system also acts a protector to all the of the soft tissue organs, they can also move to be used as a defense of the body from outside forces. The skeletal system also helps create red bone marrow, that is a soft connective tissue surrounded by the hard walls of some bones that produce both

Immune system split into two forms, specific, which is targeted against an individual type of micro-organism, and non-specific. The non-specific immune systems consists of cells and antibodies which includes phagocytosis and inflammation. Inflammation, triggered by damaged cells releasing alarm chemicals that causes blood vessels to dilate and causes redness, heat and swelling, but also prevents the infection from spreading and increases the speed of the healing process and it alarms the rest of the immune system to attract the white blood cells that conduct phagocytosis, to engulf pathogens and subsequently digesting them with lytic
