骨骼是一种矿化结缔组织,是骨骼系统的主要组成部分。骨细胞形成骨,其由胶原和磷酸钙矿物质的基质组成。体内有三种主要类型的骨细胞。破骨细胞是分解骨骼以吸收和同化的大细胞。成骨细胞调节骨矿化并产生类骨质(骨基质的有机物质),其矿化形成骨。成骨细胞成熟以形成骨细胞。骨细胞有助于骨骼的形成,有助于维持钙的平衡。从将氧气输送到整个身体到抵抗感染,血液细胞对生命至关重要。血液中三种主要类型的细胞是红细胞,白细胞和血小板。红细胞决定血型,也是将氧输送到细胞的原因。白细胞是免疫系统细胞,可以破坏病原体并提供免疫力。血小板有助于凝血,防止因血管破裂或受损而造成过多的血液流失。血细胞由骨髓产生。

澳大利亚格里菲斯大学医学论文代写:矿化结缔组织

Bone is a mineralized connective tissue that is a major component of the skeletal system. Bone cells form bone, which is composed of a matrix of collagen and calcium phosphate minerals. There are three main types of bone cells in the body. Osteoclasts are large cells that break down bones to absorb and assimilate. Osteoblasts regulate bone mineralization and produce osteoid-like (organic material of the bone matrix) that mineralizes to form bone. Osteoblasts mature to form bone cells. Bone cells help bone formation and help maintain calcium balance. From transporting oxygen throughout the body to fighting infection, blood cells are vital to life. The three main types of cells in the blood are red blood cells, white blood cells and platelets. Red blood cells determine blood type and are also responsible for delivering oxygen to cells. White blood cells are cells of the immune system that destroy pathogens and provide immunity. Platelets help to clotting and prevent excessive blood loss due to ruptured or damaged blood vessels. Blood cells are produced by the bone marrow.
