Homeostasis is for the procedure of the body to uphold a relatively consistent internal state. The nervous system sends and also receives these signals about temperature, blood pressure, hydration and more factors. The endocrine system tends to carry chemical messengers to adjust all the bodily functions. During different forms of exercise, the body’s internal environment is then changed and placed under a considerable amount of stress. Throughout homeostatic feedback mechanisms, the body is allowed to maintain a very healthy internal environment and then rapidly return to normal after all of the exercise ends.
Explain the concept of homeostasis. Homeostasis literally means ‘same state’. Homeostasis is when your body tries to maintain a constant condition inside your body at all times. All homeostatic mechanisms use negative feedback to maintain a constant value. Negative feedback means that whenever a change occurs in a system, this automatically causes a corrective mechanism to start, which reverses the original change and brings the system back towards the set point.
FUNCTIONS The integumentary system is essential to the body's homeostasis, or ability to maintain the internal balance of its functions regardless of outside conditions. The system works to protect underlying tissues and organs from infections and injury. It also prevents the loss of body fluids. Receiving about one-third of the blood pumped from the heart every minute, the skin and its glands help maintain normal body temperature. The system also acts as a mini-excretory system, secreting salts, water, and wastes in the form of sweat.
(5 marks) 5 organs inferior the clavicles are: Lungs- these help us to breathe but extracting carbon dioxide through the walls of the lungs. Heart- this pumps clean blood around our body to help us survive. Kidneys- the kidneys flush out all the bad nutrients from our body and produces urine. Liver- this is where bile is produced and leaves through here. Stomach- It continues the digestion
Homeostasis is the property of a system in which variables are controlled so that internal conditions remain steady and relatively constant. Examples of homeostasis contain the regulation of body temperature and the balance between alkalinity and acidity (pH). It is a process that maintains the stability of the human body's internal environment in response to changes in external conditions. (American, 2000) Homeostasis is essentially an internal biological process in which the body maintains internal equilibrium. The variable that is being monitored in homeostasis process is known as the variable or controlled variable.
Administrative controls by reducing the time employees are exposed to toxic materials or modifying their work practices can also be used. Different types of respirators are designed to protect against specific respiratory hazards.The atmosphere and the air contaminant levels that workers encounter at a site dictate the type of respirator that must be worn.Respirators are available in many types, models,and sizes from several manufacturers for a variety of applications. Air Purifying Respirators ( APR`s ) work by removing gas, vapours, particulates or a combination of these from the air through the use of filters, cartridges, or canisters. To help employees with identifying the specific
Muscle tissue contract to produce active movement. Neural tissues conduct electrical impulses and carries information. The protected regions of our body for example our kidney tubes, the lining of the ventral body cavities and the lining of blood vessels are called simple squamous epithelium, they protect regions in which absorption takes place or where a slippery surface reduces friction. Stratified squamous epithelium protects when there are severe mechanical stresses the lining of the mouth and esophagus are prime examples of the epithelium. I believe that if the cutaneous membrane was damaged it would heal in time after all it is our skin and we know that in most people it heals with the help of red blood cells.
Each of these lobes has different functions from each other. On the other hand, the neurotransmitters are the information carriers, they carry electrochemical signals to and from the brain throughout the entire body in human beings. Then, we have the nervous system which can actually be divided into two parts, the central nervous system (CNS) and the peripheral nervous system (PNS) where the brain and spinal cord are parts of the CNS. The PNS can still be divided into two specific parts, the somatic nervous system (SNS) and the autonomic nervous system (ANS). While the SNS directs the movements of the skeletal muscles, the ANS regulates involuntary processes such as the heart beating, breathing, blood pressure, and blood sugar level.
The Pituitary Gland The body contains a system for communicating, coordinating and controlling the bodies work. This is known as the endocrine system. The endocrine system works together with other systems and glands in the body to maintain and control body energy levels, reproductions, growth and development, homeostasis and responses to stress and injury. To maintain these functions, a network of glands and organs produce, store, and secrete certain hormones to complete different body functions. Hormones, which are chemical messengers, transfer information from one gland to another for important body functions.
Plasma and red blood cells transport substances to or away from cell. White blood cells and platelets are parts of the immune system. Blood plasma is mostly made up of water which is from respiration and is absorbed from the large intestine. Water can also be reabsorbed from the kidney. This is very important as this allows osmosis occurs in our bodies.
