HUMAN BODY
:smiley: :smiley: :person_with_ball::skin-tone-2:
LEVELS OF ORGANISATION
TISSUES
ARE FORMED BY SEVERAL CELLS
TYPES
SKIN TISSUE:
Covers the outside of the body.
BONE TISSUE:
Forms bones and supports the body.
MUSCLE TISSUE:
Moves the different body parts.
FAT TISSUE:
Stores fats for energy.
NERVOUS TISSUE:
Transmits information around the body and coordinates the body's functions.
ORGANS
CELLS
PARTS OF THE CELL
MEMBRANE:
Protects the cell.
NUCLEOUS:
Is the control centre of tfe cell.
CYTOPLASM:
It is the jelly liquid that is inside the cell.
ORGANELLES
RIBOSOME:
A ribosome is a small organelle involved in the process of making protein, which is called protein synthesis.
MITOCHONDRIA:
Their main job is this energy conversion. They oxidise glucose to provide energy for the cell.
CELLS ARE THE BASIC UNITS OF LIFE
ORGAN SYSTEMS HELP CARRY OUT 3 BASIC LIFE PROCESSES
NUTRITION
RESPIRATORY SYSTEM:
The Respiratory System absorbs oxygen from the air we breathe. The nutrients and oxygen pass into our blood.
CIRCULATORY SYSTEM:
The Circulatory System transports the nutrients and oxygen in our blood around our body. All waste products need to be expelled from our bodies. For example, carbon dioxide is expelled from our bodiesusing the Respiratory System when we exhale.
DIGESTIVE SYSTEM:
The Digestive System breaks down the food we eat to absorb nutrients from it. The substances that are not absorbed in the intestines are expelled in the form of faeces.
EXCRETORY SYSTEM:
Other waste products are expelled from our bodyby the Excretory System in the form urine and sweat.
INTERACTION
LOCOMOTOR SYSTEM:
The Skeletal System and the Muscular System form part of the Locomotor System; the system we use to move around.The brain processes the information and sends signals to the Locomotor System to move.
ENDOCRINE SYSTEM:
The Endocrine System produces substances called hormones, for example, adrenaline, wich tell our brain how to react in especific situations. The substances can make us feel scared, nervous, happy or relaxed.
NERVOUS SYSTEM:
We detect information about the world around us through our sense organs. This information is sent to the brain by the Nervous System.
REPRODUCTION:
Our Reproductive System allows us to reproduce by having children. During puberty the Reproductive System develops. As a result, we can reproduce.
FEMALE REPRODUCTIVE SYSTEM:
The female Reproductive System produces an egg cell or ovum. The fertilised egg cell then develops into a fetus in the uterus. After about nine months, the fetus is fully developed and the baby is born.
MALE REPRODUCTIVE SYSTEM:
The male Reproductive System produces spermatozoids.When a spermatozoon and a ovum conbine, fertilisation takes place.
