Connective tissue

 Features:

- loose arrangement of cells

- the presence of an intercellular substance which contains the basic substance, collagen protein fibers and elastic fibers

- maintains connectivity between different tissues

Connective tissue proper

Dense connective tissue

SOURCE

- it consists of various types of cells and an intercellular substance that contains collagen fibers

- this tissue builds: tendons, ligaments, dermis

Adipose tissue

SOURCE

- it consists of fat-filled cells

- is divided into yellow and brown adipose tissue

YET (yellow adipose tissue):

- it occurs in adults

- stores spare substances

- has a shock-absorbing and thermal insulation function

BAT (brown adipose tissue)

- occurs in newborns

- has a thermoregulatory function

- occurs in animals during hibernation -> is necessary to obtain energy and warm up

Cartilage

SOURCE

- it consists of cartilage cells that occur in cartilage pits and the intercellular substance

- it is very flexible and durable thanks to protein fibers

- this tissue builds: the auricle, elements of the larynx, and the nasal septum

- connects some bones, such as the ribs to the sternum, and covers the articular surfaces of the bones

Bone

SOURCE

- it consists of bone cells and intercellular substance

- hardness is given by mineral salts (including calcium salts) which are found in the intercellular substance

- bone elasticity is provided by collagen fibers

- this tissue builds the skeleton

Blood

SOURCE

- consists of cellular components (red blood cells, white blood cells, platelets) and intercellular substance (plasma)

- transports substances between different organs

- is involved in the body's immune reactions
