Tissues
- Epithelia
- Simple
- squamous
- function
Anmerkungen:
- Cells form into sheets and form in the protective area to allow substances through, e.g. capilliary walls allow O2, Co2 and glucose.
- structure
Anmerkungen:
- The structure of the cells is small, thin and delicate
- cuboidal
- function
Anmerkungen:
- Allows substances to pass through by diffusion. Can withstand more trauma than simple squamous epithelium. Also specialise in secreting subtances such as medcines
- structure
Anmerkungen:
- This tissue consists of single layers of cuboidal cells on the bottom of the membrane
- columar
- function
Anmerkungen:
- Columnar epithelia have goblet cells in between them which allows them to produce mucous. The mucous traps dust and germs
- structure
Anmerkungen:
- Microvilli, also known as the hairs which are on the top of the columnar epithelial cells.
- ciliated columar
- function
Anmerkungen:
- A thin tissue that has hair-like structures on it. The hairs move back and forth to help move particules out of our body
- structure
Anmerkungen:
- We find ciliated columnar tissue in our respiratory tract
- Compund
- Keratinised
- function
Anmerkungen:
- They are the layers under the cuboidal and divide to replace the surface cells which then become dust.
- structure
Anmerkungen:
- Keratinised are the dead cells which lay on the top as they are dead, they are filled with protein called keratin
- Non-Keratinised
- function
Anmerkungen:
- This tissue is found in the lining moist cavities or tubes within the body such as the mouth or cornea
- structure
Anmerkungen:
- The cells on the surface and sloughed of through friction and are replaced by new cells.
- Muscle
- skeletal
- Structure
Anmerkungen:
- Muscle tissue consist of muscle fibres that are important and capable of contraction along their longitudinal axis.
- Function
Anmerkungen:
- The function of the skeletal movement is to produce movement, maintain posture and body position, support soft tissue and maintain body temperature
- smooth
- structure
Anmerkungen:
- smooth muscle cells are shaped as rugby balls shape and are more fatty when contracted.
- function
Anmerkungen:
- Smooth muscle is not under conscious control, it is controlled by out nervous system. Smooth muscle is found in the bladder wall and stomach wall.
- Cardiac
- structure
Anmerkungen:
- Cardiac muscle is only found in the heart and is not under conscious control.
- function
Anmerkungen:
- The cardiac muscle can contract without any nervous stimulation which Is known as myogenic.
- connective
- bone
- cartilage
- function
Anmerkungen:
- Cartilage allows parts of our body to be more flexible, such as our nose and ears.
- structure
Anmerkungen:
- The cartilage allows structure and flexibility.
- function
Anmerkungen:
- Our bones store different kinds of nutrients, minerals and lipids and produces blood cells. Bones also supports our framework.
- structure
Anmerkungen:
- The bones are hard living tissue made up of calcium salts. In the middle of the bone includes a spongy type which contains blood vessiles and bone marrow which contain stem cells
- blood
- function
Anmerkungen:
- Carries around different materials such as O2, CO2, nutrients and waste
- structure
Anmerkungen:
- Small red overall shaped, does not have a nucleus but can live for 120 days.
- adipose
- function
Anmerkungen:
- a sticky white material which combines muscles groups, blood vessel and nerves system together.
- strucutre
Anmerkungen:
- Insulates and stores the energy which is made. It contain collagen and elastin fibres which makes it strechy
- nervous system
