THE ORGANISATION OF THE HUMAN BODY By Rachel Bull CELLS The organelles of cells and their function • Cell (or plasma) membrane - The plasma membrane acts as a boundary and controls what substances can enter and exit the cell. • Cytoplasm - This semi-fluid substance found inside the boundary of the cell and outside the nucleus cushions and protects the internal organelles‚ this is also where the majority of the chemical reactions happen. • Nucleus - The nucleus is the double-membraned central

What is the integumentary system? It is classified by the skin and all the accessory structures‚ which include hair‚ glands‚ and nails (Seeley’s‚ 2016). The main functions of the integumentary system are to protect our body from everything. The skin and all the accessory structures also help the body retain body fluids‚ protect against disease‚ eliminate waste products and regulate body temperature. When we think of the gross anatomy of the integumentary system‚ we are asking ourselves what we can

Fluid balance is when the quantity of water we gain each day is equivalent to the amount we lose to the environment. The upkeep of normal fluid balance includes regulating the content and sharing of body water in the ECF and the ICF. The digestive system is the main source of water gains; a small amount of extra water is generated by metabolic activity. With electrolyte balance‚ it involves balancing the amounts of absorption across the digestive tract with amounts of loss at the kidneys. Everyday

The Integumentary system maintains the body’s temperature‚ homeostasis‚ and delivers sensory information. Hair‚ nails‚ skin‚ glands and nerves are all part of the integumentary system. The integumentary systems main functions are to protect and keep the body safe from all external environments. Furthermore the roles of the integumentary system are to help control the body temperature‚ remove any unwanted toxins in the body and fight against any illness or disease. Thermoregulation is a function
