Question | Answer |
---|---|
Whats the realtionship/organsation of cells and tissues | specialised cells working together for the same function - to form tissue ( muscle cells working together to perform the same funtion) |
Whats the relationship/organisation Tissue and organs | serveral tissues working together for the same function- to form organs ( epithelial, connective, muscle & nervous tissues working together to form heat |
Whats the relationship/organisation of organs and systems | organs work in a sequence for the same purpose to make a system ( heart, arteries, veins work together to form cv systems) |
Whats the structure/function of a cell membrane in a cell | controls the passage of substances in and out of the cell |
Whats the structure/function of Mitochondria in a cell | responsible for the production of energy for the cell |
Whats the structure/function of the nucleus in a cell | its the control center of the cell controlling all functions |
Whats the structure/function of the golgi bodies/apparatus in a cell | packages and prepares proteins |
Whats the structure/function of the endoplasmic reticulum in a cell | responsible for the transport of materials within the cell |
Whats the structer/ function of cytoplasm in a cell | jelly like substance which is the site of all chemical reactions |
What is Epithelial tissues function | membranes that line or separate oragns ( line the inside of the mouth & cover organs in the body) |
What is connective tissues function | Adds support and structure to the body( ligaments, tendons |
What is muscle tissues function | formed from protein fibres that contract |
What is the Nerve tissues function | strands of neurones that transmit electrical impulses to or from the brain |
Function of cardiac muscle tissue | involunary muscle that forms heat |
Function of smooth muscle tissue | involuntary muscle forms structres such as the blood vessels and bladder |
Function of skeletal muscle tissue | voluntary muscle is responsible for the movement of theskeletal sytem and generates heat |
Whats the Skeletal systems main organs and basic function | main organs -humerus, vertebrae - function is supports ,protection& calcium store |
Whats the muscular systems main organs and basic function | main organs- gastrocnemius, deltiod- function is provides movement |
Whats the cardiovascular systems main organs and basic function | main organs- heart, artries- function is circulate blod in the body |
Whats the respiratory systems main organs and basic function | main oragns- lungs, diaphragm - function is inhale oxygen and exhale carbon dioxide |
Whats the nervous systems main organs and basic function | main organs- brain, neurones- function is controls all body functions |
Whats the endocrine systems main organs and basic function | main organs- adrenal gland, pancreas- function isproduce chemicals to maintain homeostasis |
Whats the urinary systems main organs and basic function | main organs- kidneys,liver- function remove waste, balence water and salt levels |
Whats the digestive systems main organs and basic function | main organs- stomach,large intestine- function is breakdown food for absorption |
What is Diffusion | the net movement of molecules from an area of high concentration to an area of low concentration along a concentration gradient |
Where does the diffusion process occur | in the lungs where oxygen moves from a high concentration in the alveoli to the low concentraion in the blood capillaries |
What is osmosis | the net movement of water molecules from an area of high water concentration to an area of low concentration through a semi permeable membrane |
Where does osmosis occurs | there is a high water concentration within the blood, the moleclues will move toward the low water concentration in the kidney tubules |
When does Active Transport occur | when you want to move molecules or ions across the membrane agasint a concentration gradient |
