The human body is a very complex organism. We don't even have machines that are as powerful or complex as just one organ in our body, the brain. Everything we covered in science class this year can be directly impacted by us, Humans. The human body is made up of millions of cells. The cells create tissue, which is a group of cells that all work together for one main purpose. The Tissue creates organs, which are two or more tissue that works together to coordinate and perform a task. When organs

Human Body Systems is a yearlong class with a prerequisite of principles of biomedical science. This course explores and expands on many ideas that were broadly covered in Principles of Biomedical Science with more depth. Emphasis will be put on designing experiments to examine identity, power, movement, and homeostasis. There will also be focus on investigating structure within the human body and how those structures work together. I will also

Introduction The integumentary system is one of the largest and most integral organs in the human body, encompassing many structures and playing key roles in the protection and general function of the body (Zimmermann, 2014). As with everything however; things can go wrong, failures can occur causing the system to function at a level below what is required of it. It is at this point where we must be active in our response to these faults and subsequently utilise knowledge and techniques in order

October 2017 Human Body System: Excretory System The human body is an intriguing concept, with eleven different systems all working simultaneously to make life possible. All of these systems are essential to a living organism in their own way, but one of the most important aspects of a human body is the excretory system. This system allows one to excrete toxic waste from their body that is produced by homeostasis. There are many different organs that are located all throughout the body which are included

The integumentary system plays an intrinsic role in the function of the human body. The system is made up of the skin and skin derivatives such as hair, nails, glands and receptors and provides the body with a line of defence against foreign, infectious pathogens (Moore et al., 2013). The skin is the most vulnerable organ to injury and disease as it is an external organ and the largest organ of the body, contributing to approximately 15% of the body’s weight (Hackman, 2014). The skin also helps to

The hemostatic system of the human body is responsible for the complex task of maintaining blood in a liquid state in order to effectively circulate in our veins and arteries, while simultaneously being able to convert blood into fibrin and prothrombin at sites of injury. Deep vein thrombosis (DVT) is formed in the setting of reduced-flow and low-shear stress, and is made up of fibrin strands, red blood cells and platelets. In 1856, Rudolf Virchow postulated that ‘hypercoagulability’ of the blood

The femur, is the longest, heaviest, and strongest bone in the entire human body. In the human body, all of the body’s weight is supported by the femurs which are located in the human thigh. The femur is classified as a long bone and extends from the hip down to the knee. The head of the femur articulates with the pelvis to form the hip joint. The neck is a narrow connection between the head of the femur and the diaphysis of it. The diaphysis is the shaft of the bone and the facet is the small smooth

The Integumentary System plays an extensive role in our everyday lives. It consists of hair, skin, nails, and glands. Therefore, it is one of the largest organ systems that can be seen and in the human body. All these structures help protect the inner portion of the body. But the most important structure overall is the skin. The skin is used as a waterproof layer protecting everything on the inside of the body. The skin regulates the temperature of the body and the moisture. It also works as

Introduction One of the very complex systems in the human body is the digestive system where many experiments have been conducted to determine the necessary factors to breakdown food. The digestive system uses enzymes in order to break down the macromolecules that humans consume daily and balances the fluid that gets put inside the body with the amount that goes out. It goes through four processes as follows: digestion which breaks down food into smaller components, absorption which absorbs

While medication can aid in sickness, the human body is actually built to naturally defend itself using the immune system. The immune system is comprised of biological structures and processes that protect the body from pathogens which cause disease or sickness. As much as the immune system does to protect us, it is the chief hurdle of transplantation of living cells from one organism to another. The immune system recognizes anything foreign put into the body as a threat that must be removed. Consequently
