Epithelial tissues

Location of simple cuboidal epithelial tissue and their organ systems

Kidney tubules (urinary system) , Glands (endocrine system) , Thyroids (endocrine system) , Bronchioles (respiratory system)

Role of kidneys tubules in urinary system

For reabsorption and secretion of substances and water balance

Role of Glands in endocrine system

Secretion and reabsorption of useful substances and the good passage line for substances to travel

Role of thyroids in the endocrine system

Hormone production, storage and release, and metabolic regulation

Role of bronchioles in the respiratory system

air conduction, protection and detoxification, mucus clearance (cilia), transition to gas exchange and smooth muscle control

Structure of simple cuboidal epithelial tissue

Single layered cell, nucleus is large and is n the centre of cell, cells tightly packed together, cube shaped cells,

Location of simple columnar epithelial tissue an their organ systems

stomach, small and large intestines, gallbladder ( digestive system), uterus

(female reproductive system) and spinal cord and ventricles of brain (nervous system)

Role of stomach, small and large intestines and gallbladder in the digestive system

has microvilli which is typical for increasing surface areas for absorbing nutrients and secreting mucus and enzymes while digesting food

Role of the uterus in the female reproductive system

protection of uterus lining and absorption of nutrients for the embryo and facilitates transport of mucus and fluid transport

Role of spinal cord and ventricles of the brain in the nervous system

producing, circulating and absorbing cerebrospinal fluid (CSF) and acting as a barrier and supporting neural brain stem cells

Structure of simple columnar epithelial tissue

its nuclei is large and oval shaped, has microvilli ( increases SA), cilia (moves substances) and non-ciliated in stomach and small intestines and is single celled

Location of simple squamous epithelial tissue and their organ system

Alveoli (respirator system), arteries, veins and capillaries (lymphatic and cardiovascular system), and the kidney lining (urinary system)

Role of alveoli in the respiratory system

gas exchange, thin diffusion barrier, good surface area, and structural support

Role of arteries

pressure regulation, blood flow control and transportation of oxygenated blood and fluid balance

Role of veins

transportation of deoxygenated blood, low resistance, immune function and fluid collection

Role of capillaries

material exchange, filteration, reabsorption, lymph formation, fluid balance and fluid collection

Role of kidney tubules

Structure of simple squamous epithelial tissue

single celled tissue, cells are tightly packed, smooth membrane for rapid diffusion and filteration and have a flattened nucleus

Location of stratified squamous epithelial tissue and their organ system

Outer layer of the skin (Epidermis), pharynx (respiratory system ), oesophagus (digestive system)

Role of the epidermis (outer layer of skin)

forms the skins outer protective barrier, prevents water loss, blocks microbes and defends against skin and UV damage

Role of the pharynx in the respiratory system

mechanical protection, barrier against pathogens and its continuity with the oesophagus

Role of the oesophagus in the digestive system

protection from abrasion from food, barrier function, structural support and limited acid resistance

Structure of stratified squamous epithelial tissue

multiple layered (2 layers), cells are flat, attached to a basement membrane
