Cells, Tissues, Organs, Systems Flashcards
Cell membrane structure & function
Semi permeable membrane that encloses the cytoplasm
Controls what goes in and out of the cell
Muscular System & 3 organs / parts
Creates movement and maintains posture
Bicep
Deltoid
Obliques
Skeletal System and name 3 organs / parts
Support and protects the organs, Calcium store.
Femur
Humerus
Sternum
Cardiovascular system and name 3 organs / parts
Pumps the blood round the body transporting nutrients and waste
Heart
Arteries
Veins
Nervous system and 3 organs / parts
Controls all body functions, responds to external or internal stimuli
Brain
Spinal cord
Nerves (neurones)
Lymphatic System & 3 organs / parts
Forms the immune system to fight infection, involved in recovery after injury
Spleen
Lymph nodes
Lymph vessels
Respiratory system & 3 organs / parts
Takes oxygen into the body and releases carbon dioxide
Lungs
Trachea
Diaphragm
Endocrine system & 3 organs / parts
Uses hormones to control body processes
Adrenal gland
Testes
Growth hormone
Digestive system & 3 organs / parts
Breaks down food, absorbs nutrients and packages waste
Stomach
Small intestine
Gallbladder
Urinary System & 3 organs / parts
Removes waste and balances water and salts
Kidneys
Bladder
Urethra
Reproductive system & 3 organs / parts
Produces offspring
Penis
Ovaries
Vagina
Epithelial Tissue structure & function & example
Tissues that lines and separates. Able to protect, absorb, excrete, secrete
Sweat glands under arms, human skin
Connective tissue basic structure & function & example
Adds support and structure to the body.
Tissue able to provide attachment, structure, support & protection
Tendons (muscle – bone)
Ligaments (bone – bone)
Transportation of red blood cells around the body
Muscle tissue structure & function & example
Is Unique as has ability to contract
Can be voluntary or involuntary movements.
Smooth, skeletal and cardiac.
Nervous tissue function & structure & example
Tissue able to transmit electrical impulses
Nerves, brain tissue, spinal cord tissue
Cell membrane structure & function
Semi permeable membrane that encloses the cytoplasm
Controls what goes in and out of the cell
Mitochondria function
Produces energy in the form of ATP
Cytoplasm
Jelly like substance and is the site of where chemical reactions take place
Nucleus
Controls all functions of the cell
Endoplasmic Reticulum
Processes materials for transport in the cell
Golgi Bodies
Process and packages materials for transport out of the cell
Ribosomes
Site of protein synthesis
Cells to tissues relationship & EG
Groups of specialised cells with similar structure and function group together to form tissues
tissues to organs relationship & EG
Several specialised tissues arranged to work together for a specific function are described as organs
Organs to systems relationships & EG
Organs that work together for the same general purpose are arranged in a series to for a system. Systems of the body work together to maintain balance (homeostasis) & health
Tendon joins?
Muscle to bone
Ligament joins?
Bone to bone
Osmosis
Movement of water molecules from a high concentration gradient to a low concentration gradient through a semi permeable membrane
Diffusion
Movement of gases from a high concentration gradient to a low concentration gradient along a concentration gradient
Active transport
Uses energy (ATP) to move molecules against the concentration gradient from an area of low concentration to an area of high concentration
