A Brief Look At Homeostasis, The Disease, And Treatment

William Li mentions the blood vessels in his talk. Human’s body is literally packed with them. The smallest blood vessels are called capillaries, it is the vessels of life and are feeding cancer cells, bringing oxygen and nutrients. Also, it can be the vessels of death. We have got nineteen million of them in our bodies. Blood vessels are adapt our bodies no matter where they grow in our bodies.

Blood vessels are hollow (this hollow space is called the lumen) so as to allow the blood to pass through. They are also lined with endothelium, which prevents the clotting of the blood that passes through.

Blood is a bodily fluid that transports oxygen and nutrients to the cells within the body. Blood has plasma that lets the different types of blood travel round the body. Plasma contains proteins that have different functions for the blood- clotting, transporting and defence organisms and osmotic organisations. The plasma carries the red blood cell which has a elastic membrane so it can fit through the small capillaries within the body. Red blood cells can be also known as erythrocytes they don’t have a nucleus when they are matured which gives a bigger space for oxygen, although as there is no nuclei the red blood cells can’t divide so they only live for around 120 days. Red blood cells gain their colour from haemoglobin, oxygenated blood which is known as arterial blood which flows through the arteries coming from the heart and

Connective tissue - Connective tissues holds and binds everything together which are found all around the body. This type of tissue is also called fibrous connective tissues as they are consisting of a lot of fibres eg. Collagen and Elastin.

Homeostasis imbalance can result from three main influences; internal influences, external influences and exposure to environmental toxins. The homeostatic system responds to environmental fluctuations to maintain internal equilibrium and balance (homeostasis). For example, if the environmental temperature drops or increases dramatically the homeostatic system will respond to return the body to the optimum temperature (set point) of 37 degrees Celsius. The body uses a negative feedback system regarding temperature to maintain homeostasis, this is called thermoregulation. If the body temperature starts to drop towards becoming hypothermic body will react to return the body to homeostasis. First, the temperature receptors in the skin detect the

Blood contains nutrients from the foods you eat and oxygen from the air you breathe. It also

Homeostasis is a biological process that maintains a constant internal environment, regardless of what is going on in the external environment. This process ensures the bodily functions and chemicals are kept in a state of balance which in return allows the body to function optimally. Homeostasis requires coordination of the hormonal (endocrine system) and nervous systems, which together regulate the activity of the body’s organ systems. The regulatory activities are constantly adjusted in response to stimuli (change) from both the internal and external environment. A change influenced by the external environment can cause a state in the body that will take it away from the normal, the body will act to counteract this change and return the internal environment back to a steady state. This is negative feedback. Negative feedback has a stabilising effect reducing changes from a set point and returning internal conditions to a steady state. Most body systems e.g. controlling blood glucose levels, obtains homeostasis through negative feedback which makes the negative feedback system critically important in obtaining homeostasis. However there is also positive feedback which is a system that results in the escalation of a response to a stimulus. It causes instability in the system and is used when there is a specific outcome required. Positive feedback ceases once the natural resolution is reached e.g. baby is born, pathogen is destroyed, blood clot forms. This system is not used

Blood has many functions and is a complex structure of cells and fluid. It helps fight bacteria, protect the body from infection, carry valuable sources of minerals and nutrients around the body, dispose of waste materials, keeps the body temperature regulated and helps with glandular distribution of hormones and enzymes.

Few people are aware of Raynaud's disease even though it is a fairly common condition. Raynaulds Disease is also referred to as Raynauld’s phenonmenon. Raynaud's is a condition in which cold temperatures or stress cause blood vessel spasms that block blood flow to fingers, toes, nose, and ears. This causes these body parts to suddenly turn ice cold and to become a purple or blue color. Later when the blood flow becomes normal the area turns a reddish color and later returns to normal. There are two types of Raynaud's Disease, primary Raynaud's disease and secondary Raynaud's disease. Primary Raynaud's is when a person has no other cause or condition. Secondary Raynaud's is when there is another condition that

Blood is made up of straw coloured plasma, the matrix, in which various types of blood are carried. Plasma is mainly water where substances are carried such as oxygen and carbon dioxide, nutrients such as glucose and amino acids, salts, enzymes and hormones. Also there is a combination of important proteins which help with blood clotting, transport,

Homeostasis Homeostasis works to maintain the organism's internal environment, where the body's processes are able to function at a level that would allow life to continue in that organism. The three systems which are controlled by homeostasis are the respiratory, cardiovascular, and muscular systems. Changes to the cardiovascular system are often a result of changes in the activities of other systems.

Homeostasis is the body’s way of maintaining a steady balance in the internal organs regardless of fluctuations in the external environment. Homeostasis is an important function in all humans and animals as keeping a stable environment requires constant adjustments as the environment changes. Homeostasis requires the coordination of both the endocrine (hormonal) and nervous systems; they regulate the body’s internal organs.

Homeostasis is the ability of the the body to maintain a stable internal environment despite changes. For example, “The body can control temperature by making or releasing heat.” When the body is making heat it and releasing heat it is in order to maintain the usual human body temperature, 98.6 degrees Fahrenheit. Senses is a faculty by which the body feels an external stimulus: one of the faculties of sight, smell, hearing, taste and touch. A sense organ, or sensor, dedicated to each sense, sight (vision), hearing (audition), taste (gustation), smell (olfaction) and touch (somatosensation) are the five traditionally recognized senses. The five senses are located on different parts of the human body, for example, the eyes translate light into

Homeostasis is the maintenance of near constant conditions/ state of the internal environment of an organism, this is important for the organism as it needs to maintain a near constant internal environment, it does this by allowing the body cells to function at optimal levels so internal and external influences don’t affect the state and conditions of the organism. An example of a homeostatic system is blood glucose regulation. It is the process that is maintained by the body for the levels of blood sugar; glucose, Glucose regulation is a process in the body that keeps it in homeostasis; insulin and glucagon are the main hormones involved in the process. Blood glucose is produced from food we eat, especially carbohydrates, fats and proteins, this is the main source of energy for the human body. Blood glucose is transported to the cells by the circulation and into cells by glucose transporters; some are regulated by insulin. Insulin is one of the hormones produced by the pancreas in which regulates the glucose levels in the blood around the body. Glucose is needed for respiration and the concentration levels of glucose in the blood is important to be kept and maintained at a near constant level (70 to 115mg, in a normal adult). Hyperglycemia means high blood glucose levels, this can caused by several factors such as poor food/ diet and physical activity choices and even illness. The body needs glucose to properly function due to being

The blood is categorised as a connective tissue which is one of the primary tissues found in our bodies. Connective tissue are made of tendons and ligaments that connect the tissue together, as well as bone and cartilage to support the body. This is why connective tissues are described as tissues that protect organs and maintain the form of the body. Blood is classified as this type of tissue because the blood has the same origin as the other connective tissue types and the other reason is because the body like the tissue connects the systems of the body together transporting nutrients, energy, and excreting waste products.
