Structure Of Tissues

Extracts from this document...


Unit 5 P2: Describing the Structure of Tissues Tissue Diagram Structure Epithelial: Simple 1 There are three types of simple epithelia: Squamous, Cuboidal and Columnar epithelium. Squamous cells are very flat with the nucleus forming a lump in the centre. Their main function is to allow materials to pass through using osmosis and diffusion. Squamous epithelium is found in the lung alveoli which are found in the respiratory system and blood capillaries which are found in the circulatory system. Cuboidal epitheliums are cube-shaped with spherical nuclei. They line tubes and can allow materials to pass through in ways similar to Squamous epithelia. They can be found in kidney tubules (found in the renal system), sweat ducts and glands including the thyroid gland and breast tissue and glands can be found in the endocrine system. Columnar epithelium is tall with slightly oval nuclei. They are often associated with cilia which are microscopic filaments. ...read more.


Erythrocytes have no nucleus which allows them to have a larger surface area for exposure for oxygen, the oxygenated blood gains it's oxygen from the lungs in the respiratory system. Connective: Cartilage 4 Cartilage is a smooth but firm substance that protects bone ends from friction during movement. Unlike other connective tissues, cartilage does not contain blood vessels and also grows and repairs more slowly. Cartilage is found between bones (found in the musculo-skeletal system), the rib cage, the ear, the nose, the bronchial tubes (found in the respiratory system) and the intervertebral discs. Connective: Bone 5 Bone is a much harder substance than cartilage but can be worn away by friction. Bone is made to bear weight and the limb bones are hollow, it is also used to protect weaker tissues such as the brain, lungs and heart which the heart is a vital part of the circulatory system. Bone can be found in the musculo-skeletal system. ...read more.


Muscle: Non-Striated 9 Non-striated muscles work independently, and not under the control of the brain. This muscle is also called smooth muscles because they appear smoother than other muscles. Smooth muscles can be found throughout your body including in your blood vessels what're in the circulatory system and also in your digestive system, They are used to move food through your digestive system, regulate blood flow, and increase the size of your eye pupils when there is too much light. Muscle: Cardiac 10 This muscle is the only muscle found in the 4 chambers of the heart, which is found in the cardiovascular system. These muscle cells gather together to form a group which contraction spreads quickly. The nervous system controls the rate of contraction to adapt the flow of blood when you're resting or exercising.
