Homeostasis: the body in a state of perfect balance
Function: They provide structure for the body, take in nutrients from food, convert those nutrients into energy, and carry out specialized functions.
Function: harvesting energy, making new proteins, getting rid of waste
Nucleus: it stores the cell's hereditary material, or DNA, and it coordinates the cell's activities
ribosomes: a cell structure that makes protein
DNA/chromosomes: the long-term storage of information/responsible for containing the instructions that make the offspring unique while still carrying traits from the parent
lysosomes: are organelles that contain digestive enzymes digest excess or worn out organelles, food particles, and engulfed viruses or bacteria
Cell Membrane: The cell membrane controls the movement of substances in and out of cells and organelles
Function: to send chemical messages throughout the body via hormones
How It Maintains Homeostasis: it uses a negative feedback loop to control the amount/ratio of hormones to molecules
the endocrine system is connected to the cell membrane because it sends out hormones that are then detected by the cell membrane.
Nervous System: a) Responsible for the control of the body and communication among its parts. b)The nervous system maintains homeostasis by controlling and regulating the other parts of the body and by using electrochemical signals to respond to incoming threats.
The nervous system is connected to the cell membrane because the neurons each have a cell membrane that receives and sends out one long continuous message.
Respiratory System (a) Function: to circulate oxygen throughout the body (b) how it maintains homeostasis: it keeps a steady level of oxygen in the blood and gets rid of carbon dioxide
The respiratory system is connected to the cell membrane because, in the alveoli, carbon dioxide and oxygen diffuse through the cell membrane of the alveoli.
Circulatory System: function: to pump blood, oxygen, and nutrients to all the cells and remove waste.
The circulatory system is connected to the cell membrane because it delivers nutrients to the cells to take in through the cell membrane and takes out all the waste.
The circulatory system is connected to the excretory system because the circulatory system delivers cell waste to the excretory system to be disposed of.
Excretory system: function: to get rid of, or reuse the body's waste; how it maintains homeostasis: it keeps the body at a "cleaner" state.
The excretory system is connected to the cell membrane because it removes the cell's waste.
The excretory system is connected to the circulatory system because the circulatory system delivers cell waste to the excretory system to be disposed of.
