. Flashcards
What’s epithelial tissues?
Sheets of cells that are make coverings and linings of the body and organs and organ systems
What’s connective tissue
Provide structural support for bones and cartilage in the skeletal system
What’s muscle tissue?
Contraction of muscle tissue gives movement and also aids internal processes like digestion
Nervous system
Conducts electrical impulses through the body meaning fast transfer of information
What’s the function of the epithelial tissues
Protects all internal tissues and organs
What are the different types of muscle tissues
striated- control enabling to move bones
Non striated- internal body processes and functions
Cardiac- in the heart wall, controls and never tiers
What hormone does the pituitary gland produce
Adrenocritictropic hormone
Follicle stimulation hormone
What hormone does the thyroid gland produce
Thyroxine
Triiodothyronine
What hormone does the pancreas produce
Insulin
Glucagon
What hormone does the adrenal gland produce
epinephrine and norepinephrine
What hormones does the ovaries produce
Oestrogen
Progesterone
What hormone does the testes produce
Testosterone
What is a amylase
It’s made in the mouth and pancreas’s and it breaks down to complex carbohydrates
What is lipase enzymes
It’s made up in the pancreas and breaks down fats
What is protease enzymes
it’s made in the pancreas and breaks down proteins
What is esophagus
It’s hallow muscular tube that carries food and liquid through your throat and stomache
What is fibrous?
They are connected by dense connective tissues consisting of collagen etc skull and pelvis
What is the cartilaginous?
Slight movement meaning bones separated by disc of cartilage
What is homeostatic mechanisms
The ability or tendency to maintain internal stability in an organism
Homeostasis what is it?
A state of balance around all the body’s system needed for the body to survive and function correctly
What should enzymes must have
Enzymes in a body cells must have the correct temperature to be able to catalyse chemical reactions
What’s the role of the hypothalamus
Keeps your body in a stable state and controls the coordinating centre
What’s the role of the automatic system
It regulates health rate and blood pressure
What’s aerobic respiration
Chemical process where oxygen is used to make energy from carbohydrates
Anoerobic respiration what is it?
Occurs without oxygen and realises less energy
What is catabolic reactions?
Large molecules being broken down into smaller molecules
what’s a genotype
The set of genes that an organism possesses
What’s a phenotype
Physical appearance of an organism
What’s an allelel
Different forms of the same gene
What’s. Homozygous
When two alleles are identical e
What is heterozygous
Two alleles that are different
What is dominant
Allele which controls the characteristics
What’s recessive
Allele only shows up in both chromosomes
What is cell devision
The process which cells are formed for growth, repair and replacement in the body
What causes cell devision
Replaces old, dead or damaged cells
What does the cel membrane do
Controls what goes in and out
What does mitrochondria do
Chemical reactions take place and respiration
What is chlorophyll
Where photosynthesis takes place
What does the Golgi do
Packages molecules processed by endoplasmic to be deported
Lymphnodes what does it do?
They function as filters, trapping viruses, bacteria and other causes of illnesses before they can infect other parts of your body.
What does the appendix do
acts as a storehouse for good bacteria, “rebooting” the digestive system after diarrheal illnesses.
Bone marrow what does it do?
manufactures bone marrow stem cells and other substances, which in turn produce blood cells.
What does the tonsills do?
they can stop germs entering the body through the mouth or the nose
What does thymus do?
train special white blood cells called T-lymphocytes or T-cells.
What does the spleen do?
controls the level of white blood cells, red blood cells and platelets (small cells that form blood clots) It screens the blood and removes any old or damaged red blood cells
Non striated tissue
Movement of the body parts, they are smooth and long.
Striated tissues
Convert chemical energy to physical work.
They force and contract in order to support respiration
Nervous tissue
Coordinating and controlling many body activities
