intEGUMENTARY SYSTEM dude

functions!

protects from the invasion of pathogens

helps keep the body from drying out

act as storage for fatty tissue

produces vit d

provides sensory input

regulates body temperature

THE 3 LAYERS OF SKIN EPIDERMIS,DERMIS AND SUBCUTANEOUS FASCIA

EPIDERMIS-HAVE 5 OR 6 SMALL LAYERS,NO BLOOD VESSELS,REPLACEMENT FOR DEAD SKIN CELLS(2 TO 4 WEEKS)

DERMIS-INFERIOR TO THE EPIDERMIS,HAS DENSE CONNECTIVE TISSUE TRUE SKIN

SUBCUTANEOUS FASCIA-HYPO DERMIS,HAS LIPOCYTES,INNER MOST LAYER

MUSCULAR SYSTEM DUDE!!!

i learned that there are distinct types of muscles

skeletal muscles,cardiac muscles and smooth muscles

agonists-primary movers,the muscles that cause the primary movement

point of origin-the muscles that attached to the stationary bone

point of insertion-muscle end that is attached to the moving bone

SKELETAL SYSTEM

basic functions:

It protects our vital organs such as the brain, the heart, and the lungs.

It gives us the shape that we have

It allows us to move. Because our muscles are attached to our bones, when our muscles move, they move the bones, and we move.

produces red blood cells

When you were born, your skeleton had around 350 bones. By the time you become an adult, you will only have around 206 bones. This is because, as you grow, some of the bones join together to form one bone.

ur bones don't simply work on their own. The bones join together to form joints. The end of each bone is covered by a tough, smooth shiny substance called cartilage. The cartilage-coated bone-ends are kept apart by a thin film of slippery fluid that works like oil in a car. All of this is so your bones won't scratch and bump against each other when you move. Our bones are held together by strong stretchy bands called ligaments.

TISSUES

Tissue is a cellular organizational level intermediate between CELLS and a complete organism. when tissues combine they form organs. tissues have four types namely epithelial, connective, nervous and muscle. they have different functions. epithelial tissues covers our whole body, connective tissues holds tissues together for bones and muscles, muscle tissue is divided into three skeletal muscle, the smooth muscle and the cardiac muscle, nervous tissues are mainly for communication between organs.

VVIIIIDDDDDEEOOOOO IN BIO:D

mmmmeiiosis!!!!!!!!!!!!!!!!!!!!!LOL

MEIOSIS


-NUCLEUS SPLIT TWICE
-SISTER STRANDS(CHROMATIDS)
-PATERNAL AND MATERNAL CHROMOSOMES LINE UP IN THE MIDDLE OF THE CELL
-MEIOSIS OCCUR ONLY IN SPECIALIZED CELL
-HOMOLOGOUS CHROMOSOMES AND CROSSING OVER APPEAR ONLY IN MEIOSIS

MITOSIS
The term Mitosis refers to the division of the nucleus that becomes the cause of nuclear cell division that results in a two sets of similar chromosomes. mitosis takes place with cytokinesis that becomes to cause of two utterly different cells that are known as daughter cells. Prophase, metaphase, anaphase and telophase are four phases of mitosis.

CELL...........

-basic unit of life
-smallest unit in life classified as living thing
-parts of animal cell
.nucleus
.nucleolus
.er(ser and rer)
.ribosomes
.cytoskeleton
.golgi apparatus
.cytoplasm
.mitochondria
.lysosomes
.centrosomes

LIPIDS

THE TERM LIPID IS A SYNONYM OF FATS.
LIPIDS IS DEFINED AS HYDROPHOBIC.
THERE ARE TWO TYPES OF LIPIDS COMPLEX AND SIMPLE.
COMLEX IS A LIPIDS WITH FATTY ACID, WHILE THE SIMPLE LIPID HAVE NO FATTY ACID



NUCLEIC ACIDS (:

A POLYMERIC MOLECULES THAT STORE AND TRANSFER INFORMATION WITHIN A CELL.
THE TWO TYPES OF NUCLEIC ACID IS DNA AND RNA.
DNA IS THE GENERIC MATERIAL DETERMINING THE PROTEINS TO BE MANUFACTURED.
RNA PLAYS A VITAL ROLE IN THE PROCESS OF PROTEIN MANUFACTURE.

PROTEINS!!

Proteins is an organic compound that made up of amino acids. Proteins are fundamental components of all living cells and include many substances, such as enzymes, hormones, and antibodies, that are necessary for the proper functioning of an organism.






CARBOHYDRATES!!

As we all know carbohydrates is an organic compound.
Carbohydrate is our main source of energy.
Humans break down carbohydrates during the process of metabolism to release energy.
All of carbohydrates are made up of units of sugar.
Carbohydrates are divided in to 4 groups: disaccharides,monosaccharides,polysaccharides and oligosaccharides.
Carbohydrates are commonly referred as sugar.
Monosaccharides are carbohydrates that cannot be hydrolyzed.
Disaccharides are any class of sugar that composed of 2 monosaccharides.
Polysaccharides are complex carbohydrates that made up of chains of monosaccharides.
Oligosaccharides a carbohydrate that consists of a relatively small number of monosaccharides.
