Epithelial
Cuboidal – cube shaped, prominent
nucleus. Can be found in medulla of kidney.
Does not allow for passive diffusion easily.
Columnar – tall, vertical, thick cells. Can be
found in the small intestine. Does not allow passive diffusion easily. Active transport is needed. Move nutrients from intestine to blood = absorption! Can have microvilli to increase surface area.
Squamous – large, thin and prominent
nucleus. Like a sunny side up egg. Can be found in glomerulus of kidney, walls of capillaries, alveoli of lungs. Allows for diffusion easily.
Ciliated – Tall cells with small finger-like
projections. Give a waving motion to move mucus. Connective …show more content…
White Blood Cells (Leucocytes)
Lymphocytes – some secrete antibodies, some kill infected cells and control aspects of immunological process.
Monocytes – engulf bacteria.
Granulocyte – 3 types; neutrophil,
eosinophil, basophil, Some engulf bacteria, others involved in allergies and inflammation. Platelets for clotting. Can be sticky.
Cartilage – cells in a strong, flexible protein.
Does not stretch but is flexible. Supports softer tissues in nose, ear, trachea. Also acts as shock absorbers in spine. Contains elastin and collagen fibres.
Bone – formed from calcium salts deposited
around proteins. Calcium salts are rigid, protein fibres provide elasticity and strength Areolar – contains cells called fibroblasts
separated by non-living matrix. Collagen fibres for flexibility, elastic fibres for stretching. Found in skin, most internal organs (for expansion), muscles/blood vessels/nerves for protection.
Adipose – large fibroblasts to store fat.
Purpose is to store energy, insulate and provide padding. Found around the kidneys and heart.
Muscle
Striated – attached to bones by tendons
