Unit: 5 Anatomy and Physiology for HSC
Transcript of Unit: 5 Anatomy and Physiology for HSC
Physiology- is how the body works.
The average person flatulence at least 22 times in a day.
If you lay the vain and arteries out, they could stretch at least twice around the world.
There are over 2000 cells in the body.
When messages between cells are blocked or scrambled; it can usually result to an ammonium disease.
" You are alive as your cells are alive"
activities that a cell carries out are:
All cells work together as a unit to perform in the body.
Human and Animal Cells - Facts
There are different types of cells in the body, mainly found in tissues, and organs their objective is to repair, reproduce,oxygenate and clean the body.
Animal and human cells have similar organelles.
What is Respiration?
Respiration - is a chemical reaction called Mitochondria. This acts like a catalyst to produce energy which is then formed into food substances called glucose.
Cells Function Facts
Red blood cells - Carry oxygen around the body
Nerve Cells - they carry neuron messages from the brain, to the organs, tissues, and cells.
White Blood cells - are a form of anti- bodies which fight against bacteria or viral infections.
Platelets cells - are produced in the brain marrow, their function is to prevent overflow of blood seeping out from a cut or a wound.
Why do we need Growth?
Cells increase as you get older, They usually grow when your resting ( asleep) this gives them plenty of time to replenish.
- cells don't have a day off! They never rest.
What is a Nucleus and Chromosome?
Fact - The DNA strand consist of 24 chromosomes.
A cell nucleus controls what happens within the cell, it contains loads of chromosomes which creates a human DNA gene, this gene has different characteristics; such as eye colour, height and determines whether it will be a boy or a girl
What is a membrane?
A cell membrane is a structure like a cell, but has a fatty layered oval outer structure. This organelle stops bacteria from entering into the live cells. It sends and receives chemical messages from other cells
Live Cells Structure
Unit: 5 Anatomy and Physiology for HSC
What is Cytoplasm?
Cytoplasm is the gel like fluid which is found within the cell membrane.
Cytoplasm also holds together the shape of the cell, and everything within the cell.
What is the Mitochondria?
The Mitochondria generates energy in the cell, in order for the other cells to work and fully function.
Rough & Smooth Endoplasmic rectum
Organelles which are called rough and smooth endoplasmic rectum, is found in the membrane, which is a folded sacs.
RER - acts like a conveyor belt, it transports protein and other substances, to specific places in the cell.
SER - it also acts like a conveyor belt instead this cell has ribosomes attached which transports substances to specific places as well.
Golgi apparatus is a major Organelle cell, which is also part of the membrane, it packages protein and liquids in the membrane.
What is a Lyosome?
Lymsomes are present in every animal, they are like an (euraryotic cell) the function for a lymosoome is to break down waste, it uses an enzymes to do this, this helps it to digest food quickly.
What is a Ribosomes?
Ribosomes are small like organelle which is connected to the cytoplasm, it has a simple instruction to produce protein, it helps to transport network around the cell.
Analogy for Cell
Charlie and the Chocolate Factory
notes and information sheets given in class.
Respiration - www.bbc.co.uk>...>organisms and erngergy ( 20/10/14)
Cells and their function - www.bbc.co.uk/bitesize/ks3/science/organisms_behaviuour.../cells../4/ (20/10/14)
Cells form tissues, tissues form organs and organs form body systems.
Are there any questions?
Chocolate Factory - acts like outer cytoplasm as it contains everything within the chocolate factory.
Outer Gates - this is around the Chocolate Factory, symbolizes the Membrane stops people and things getting in.
Willy Wonka - is the nucleus, who is in command of the factory gives the instructions to the crew.
Umpa Lumpas - act like the Ribosomes, they transport and produces chocolates and sweets
Generator in the Factory - act like the Mitochondria to produce energy, enabling factory to supply chocolates.
Wonka bars - symbolizes the Golgi apparatus, the storing and producing of chocolates
Fat Kid - symbolizes the lyosmes, which gets rid of the waste in the factory.
Boat ride - acts like the SER, smoothly transporting the passengers to the destination.
Glass Elevator - when it shoots roughly towards the roof, causing a destruction in the process, symbolizes the RER as it transports substances.
