What is the hard surface of tooth made of?
The hard surface of the tooth is made of enamel which is the hardest tissue in the human body. Tooth enamel has no living cells so unlike a broken or fractured bone the body has no way to repair chipped/cracked enamel.
What is the Only substance capable of cutting diamond?
Another diamond is the only substance hard enough to cut diamond.
What is the substance that makes wood hard?
Lignin is the substance that makes wood hard. It is a complex organic polymer that fills the spaces between cellulose fibers in wood, providing rigidity and strength to the material.
What is a hard transparent substance?
One example of a hard transparent substance is glass. Glass is a solid material that is typically transparent and can be molded into various shapes for use in windows, containers, and other applications.
What are clacium and phosphorus?
Calcium is a mineral that is found in the hard parts of the bone, where it is stored. It is most commonly acquired from dairy products. It helps promote good bone health. Phosphorus is a mineral found throughout the body. It also promotes bone health, as well as giving energy. Phosphorus is managed by the kidneys, so if your kidneys begin to fail, phosphorus will accumulate in your system, causing negative health risks. Both minerals promote overall good health, so it is important to get enough of both of them.
What substances do bone cells take from the blood to keep the bone hard?
Bone cells take calcium and phosphorus from the blood to keep the bone hard and strong. These minerals are essential for bone mineralization and strength.
True or false bone cells are surrounded by calcium and phophoruos that form a hard substance?
True
Can red blood cells also become hard as a bone cell?
No, red blood cells need for ability to fold to squeeze through the narrowest capillaries.
What are the special talents of the periosteum?
The Periosteum is a tough, tight fitting layer of bone that contains nerves and blood cells. It supplies cells of the hard bone below with needed nutrients.
What is a bone?
Bone is a hard substance made of lots of composits, it has a spongy marrow centre where blood vessels are made and it has veins and stuff running through it. When you break your ankle, structures called Osteoblasts begin to repair it. It also contains more complex structures such as haversian system, canaliculi, lamellae, lacuna. blood cells are made in your bone by marrow but the blood vessels are not made in the bone, they have them but dont make them.
What is the structure of bones?
The bone is structured easilythey are hard and rough on the out sideThen they have a silky substance before the bone marrowThen in the middle there is the bone marrow a jelly like substance
Does the heart work hard to make blood cells?
No, the heart does not work hard to make blood cells. In fact, it does no work at all. Blood cells are produced in bone marrow, in cancellous bone tissue (or 'spongy tissue') within the hard casings of bone. A hormone (protein with a very specific role in the body) called 'erethropoeitin' (erethro = red blood cell, poeitin = producing) stimulates red blood cell (erethrocyte - erethro = red, cyte = cell) production within the bone marrow. Ooh I nearly forgot - the main bones with spongy bone tissue (ie. the bones that produce red blood cells) are some of your rib bones, and femur bones. The heart's got it's work cut out for it just by pumping your blood (a mixture of red blood cells AND plasma, as well as 1% 'buffer substance') around your body. If you are reading this, it means you're old enough that your heart would have pumped millions of litres of blood through your body. And by this I mean your blood volume, circulating many times. Don't forget that red blood cells only hang around for about 120 days before they break down. :)
Are Skin cells are the fastest growing type of cells in the human organism?
yes becuase, as they generate they tend to grow faster
What is the loss of function bone marrow?
Loss of function in the bone marrow can lead to decreased production of red blood cells, white blood cells, and platelets. This can result in conditions such as anemia, increased susceptibility to infections, and impaired blood clotting. Treatment may involve blood transfusions or bone marrow transplant.
Is bone marrow soft or hard?
Bone marrow is a soft, gelatinous tissue found inside the cavities of bones. It is responsible for producing blood cells and is an essential component of the immune system.
What is the substance that gives bone its hard quality?
calcium phosphate
what is the main organic substance found in bone?
A typical bone has an outer layer of hard or compact bone, which is very strong, dense and tough. Inside this is a layer of spongy bone, which is like honeycomb, lighter and slightly flexible. In the middle of some bones is jelly-like bone marrow, where new cells are constantly being produced for the blood.
