Answer:

Bone remodeling keeps bones strong as osteoclasts break down bone and osteoblasts rebuild it.  This process replaces as much as 18% of bone each year.  Bone recycling helps the body to regulate blood calcium.

Explanation:

Bone tissue is a type of specialized connective tissue that is in constant change and renewal due to the activity of its cells. Besides serving the composition of bones and, therefore, the skeletal system, it also functions as a calcium reservoir that can be used when needed.

Describe these structures found within the kidneys
garik1379 [7]
The structures are nephrons which gets blood through the [renal artery]. The nephrons also consist of the [afférent and efferent artérioles], the latter of which is much narrower causing a high pressure to exist in the [glomerulus] (blood vessels in that ball structure) so that ultrafiltration can occur and the ultrafiltrate is passed into the [Bowman’s capsule]. The Bowman’s capsule consists of podocytes which are cells that form a microscopic pore so that small molecules can pass through (ions and such). There is the [proximal convoluted tube] that makes the contents flow downwards (and allows water to exit so the water potential inside is low) and the [distal convoluted tube] that makes the contents go upwards (and allows water to re-enter which increases the water potential inside). These are both partially permeable and set up a concentration gradient for the reabsorption of water from the urine. These tubes lead into the [collecting duct] which further reabsorb the water.

All the structures of the kidney are in [ ].

Phagocytosis is a specific form of endocytosis.</span>
