Homeostasis and TransportEssential questions:
What are the main functions of homeostasis ? How does your body use homeostasis to maintain certain functions ? |
Objective:
Key Terms:
Negative feedback - regulation in which the end product of a process in turn reduces the stimulus of that same process Positive feedback -he end products of an action cause more of that action to occur in a feedback loop Active Transport - requires energy, the cell needs to transport something against its concentration gradient Passive Transport -doesn’t require energy from an area of high concentration to an area of low concentration Homeostasis - maintaining a stable internal environment suitable for sustaining life |
Summary:
Homeostasis is a process that allows cells to maintain their internal conditions, this allows the body to stay in original state because it of the negative feedback loop that it withstand. There are four homeostatic mechanisms, thermoregulation, osmoregulation, gas exchange, and the regulation of blood glucose. Each of the mechanism has a unique these things have a different aspect of the transport within the cell membrane. Thermoregulation is a process that keeps the body heat at a definite temperature, 37 C. There are a serious of things that happen today that will allow the body to reunite with the temperature that is needed, if the body temperature gets to high, hot then your body will begin to sweat so that it cools down, when the body becomes to low, cold then it’ll start to shiver to heat the body up, that's why they say when you are cold move around to allow your body to heat up. The next known process is Osmoregulation, this process is the balancing of water within the body. Just like Thermoregulation there are things that are released once there is a build up, when the amount of water/fluids gets too high then it will release urine to get the amount of water that is not needed out and when the amount of water is too low the water the water that you drink will be absorb by your Kidneys to make sure your body does not become dehydrated, EVER. The last two processes are Gas Exchange and Blood Glucose, gas exchange process is to make sure that the oxygen is always steady in the body, when there is too much carbon dioxide and not enough oxygen then the carbon dioxide that is in the capillaries go across the alveoli, the air sacs in our lungs allow the oxygen to come in as the carbon has been released. Blood glucose is the process that allows the blood in the human body to stay at a level that is safe. The pancreas stores blood glucose when the levels of blood glucose has gotten too low, the pancreas release glucagon, turning the glucagon in the liver to turn into glucose. When the blood glucose becomes too high the pancreas release insulin and the process will restart.
Transport plays a big part in homeostasis, cell membranes, photosynthesis and cellular respiration and more. Starting in the plasma membrane the two layers of phospholipids called, bilayer. Within every phospholipid they have two hydrophobic “tail” and one hydrophilic “head”.

Passive Transport is the type of transport that does not occur without energy and it has 3 different types of transport diffusion, which is the movement of ions or molecules in a concentration gradient. Another type of transport is Osmosis, it is when mater molecules moves from different ares of higher to lower water concentrations. The other type of passive transport is facilitated diffusion this relies on the membrane proteins to help molecules cross the cells.
Active Transport is the opposite of passive transport, it occurs with using energy it is also has 3 types of transport one being named exocytosis which is when substances are released from the cell. Another type of active transport is endocytosis, this transport take the extracellular material and puts into the cells by forming a membrane vesicle around it. Sodium potassium pump is the other type of active transport which moves sodium and potassium ions which cross the cell membrane.
