The skeletal system helps with endocrine regulation, protection, support, movement, calcium storage, and blood cell production. The skeletal system consists of 206 bones, in the adult human body, all of which are divided into two major divisions. One division, the axial skeleton made up from 80 bones, runs along the body’s midline and the other division, the appendicular skeleton which has 126 bones.
Compact bone, or cortical bone, makes up 80 percent of the human skeleton, which is dense and filled with organic minerals and nutrients. It is the primary bone for longer bonse such as the arms and legs.
Spongy bone, or cancellous bone, is much lighter than compact bone; spongy bone provides the body with support and flexibility. The cancellous bone may turn into compact bone through osteoblasts
Bone marrow is normally red or yellow, however at birth all bone marrow starts of as red and throughout time half of it turns yellow. The large amounts of fat cells are the cause for the yellow coloring in the bone marrow ; the body then uses those cells during starvation for required energy. The red marrow, usually found in flatter bones, such as the hip bones, signals its importance to blood cell reproduction.
An embryos skeleton is made up mostly of cartilage; cartilage is later replaced by bone over the years, through a process called ossification. The two types of ossification are intramembranous ossification that develop membranous bone and endochondral ossification that develops cartilaginous bone. Cartilage is located in places like your ears and nose, cartilage is also found near the ribs in order to expand whenever you breathe.
Joints consists of three different types fibrous joint, cartilaginous joint, and ball-and-socket j...

...blood cells, or leukocytes, There are two major classes of white blood cells; Granular Leukocytes and Agranular Leukocytes. Granular leukocytes have three subdivisions, they are neutrophils, eosinophils, and basophils. Neutrophils neutralize the bacteria that invade the body, eosinophils digests viruses that had been bound to by antibodies in the blood, and basophils release histamine to intensify allergic reactions and help protect the body from parasites.
Platelets, small cell fragments, form blood clots in order stop from bleeding out; platelets gather at a wound and try to become a barrier between the inside and the outside of the body. Once blood comes to contact with air a clot begins to form, the platelets sense that air and begin to drift apart. Platelets are made in the bone marrow and are made by the separation of the platelet-rich plasma from the the
However some of the basic bone functions include storing of crucial nutrients, minerals and lipids, producing red blood cells for the body, protect the organs such as heart, ribs and the brain, aide in movement and also to act as a buffer for pH. With the differences in all of the bones there are four things that remain the same in each bone, their cells. Bones are made up of four different cells; osteoblasts, osteoclasts, osteocytes and bone lining cells. Osteoblasts produce and secrete matrix proteins and then transport the minerals into the matrix. Osteoclasts are responsible for the breaking down of tissue. The osteoblasts and osteoclasts are both responsible for remodeling and rebuilding of bones as we grow and age. The production of osteoclasts for resorption is initiated by the hormone, the parathyroid hormone. Osteocytes are the mature versions of osteoblasts because they are trapped in the bone matrix they produced. The osteocytes that are trapped continue making bone to help with strength and the health of the bone matrix. The bone lining cells are found in the inactive bone surfaces which are typically found in
An osteoblast is a “baby” bone cell whose main job is to secrete osteoid which forms the hardened, or calcified, bone matrix. Osteocytes are formed from osteoblasts. Osteocytes are the mature bones cells that have been completely differentiated. They are found in the lacunae of hard bone and have a spider-like appearance due to their canaliculi. Osteoclasts are a different type of cell formed from the mesenchymal cells. These cells are not related to osteoblasts or osteocytes. Their job is to basically “eat” the bone to create cavities and other hallow spaces during bone remodeling. Finally, the cells form differentiate to form fibroblasts and fibrocytes. These fibroblasts and fibrocytes secrete and form the matrix for fibrous connective tissue which is an essential component of the
Bones of the skeletal system serve as storage compartments for vital minerals like phosphorus and calcium. Excessive calcium in the blood is stored in bones. Calcium is released from the bones into the blood when there are deficient amounts of it in the blood.
The skeletal system consists of 206 bones and has other body attachments that assist in connecting them which are tendons, ligaments, and cartilage. The skeletal system provides vital functions for the human body. The functions this system provides are support, movement, protection, blood cell production, storage for calcium and endocrine regulation. Bone serves as the basic unit of the human skeletal system. Ossification is characterized as a process that produces new bone. This process is also known as bone formation. Bone formation consists of two types of development. They are intramembranous and endochondral formation. Intramembranous ossification takes place when cells within the membrane change and become osteochondral progenitor cells.
They support and bind tissue and organs together. Primary function is to support the body, allow motion and protect vital organ. The skeletal system and muscular system are two separate systems that function together. It provides movement, maintains posture, and body position. They work together through a series of impulses and signals communicated by the brain. In order for movement to happen, the nervous system signals the skeletal muscles to contract. When the muscles contract, it causes the attached bone to follow, creating movement. Bones and muscles are supported by connective tissue playing the role in structural
Bone marrow is usually red or yellow, however at birth all bone marrow begins red and throughout time half of it becomes yellow. The yellow coloring in the bone marrow is caused by the numerous amounts of fat cells; those cells are then used by the body during starvation for energy. The red marrow, usually found in flat bones, signals its importance to blood cell reproduction.
The skeletal system is made of all the bones, connective tissues and joints in the body. Bones, cartilage are some of the bones that make up the Skeletal system. The Skeletal system helps perform important everyday functions, for example; support, movement and protection, etc. The skeletal system helps form blood cells. The skeletal system helps store calcium and phosphorus, which is important and beneficial to the other functions in the body.
The three functions of the skeletal system are to support, to allow movement, and to protect. The skeleton is the framework of the body and also cradles its soft organs, with it the body would be just a jelly mass it wouldn’t have no definite shape and would just collapse. It supports the softer tissues and provides points of attachment for more skeletal muscles to hold all of the parts of the body upright. For example, the bones of the legs as pillars to support the body trunk we stand up. It also supports the body against the pull of gravity. The skeletal allows movement. The skeletal muscle attached to the bones by tendons and uses the bones as a simple mechanical lever system to move the body and its parts. All together with the muscles
The Circulatory System is a transportation and cooling system for the body. The Red Blood Cells act like billions of little mail men carrying all kinds of things that are needed by the cells, also RBC's carry oxygen and nutrients to the cells. All cells in the body require oxygen to remain alive. Also there is another kind of cells called white blood cells moving in the system. Why blood cells protect from bacteria and other things that are harmful. The Circulatory system contains vein arteries, veins are used to carry blood to the heart and arteries to carry the blood away. The blood inside veins is where most of the oxygen and nutrients are and is called deoxygenated and the color of the blood is dark red. However, blood in the arteries are also full of oxygen but is a bright red. The main components of the circulatory system are the heart, blood, and blood vessels.
Although your teeth are also considered part of your skeletal system, they are not counted as bones. Your teeth consist of enamel and dentin. Enamel is the strongest substance in your body. The main priority of the skeletal system is to provide support for the body. Without bones our body would be in a pile of guts and mush on the floor. Your skeleton furthermore assists to protect your internal organs and fragile body tissues. The brain, eyes, heart, lungs and spinal cord are all sheltered by your
There are three different types of granular leukocytes. Neutrophil is a phagocyte, produced in the bone marrow that ingests and destroys bacteria extremely fast. Neutrophil has a diameter, which is, about ten to twelve micrometers long. They make up about 60-70 percent of the total number of white blood cells in our body. Eosinphil is a type of white blood cell that secretes poisonous materials in order to kill parasites, allergies and phagocytosis of bacteria, which is when the...
The skeletal system is composed of two hundred and six bones in the human body. Functions such as the tendons, cartilage, and ligaments connect the bones and tissues together. Bone tissues make up about 18% of the weight of the human body. There are two types of tissue inside the bones. They consist of; compact bone and spongy bone. First, compact bone depicts the main shaft of long bones in the human body such as the arms and legs. Its tissue is dense and hard and it also makes up the outer layer of most bones in our body. Meanwhile, spongy bone tissue is made up of smaller plates occupied with red bone marrow. Mostly, it is found at the ends of long bones such as the head of the femur.
I will be investigating Human Blood as my specific tissue and giving an overview on the location, characteristics, and the benefits it has to the human body. Blood is extracellular matrix that is consists of plasma, red blood cells, platelets, and white blood cells. Blood is located within the capillaries/veins/arteries of the human body, which are blood vessels that run through the entire body. These blood vessels allow the blood to flow smoothly and quickly from the heart to distinct parts of the human body. The unique parts of human blood all work together for a purpose: the Red Blood Cells(erythrocytes) transports oxygen throughout the body, White Blood Cells(leukocytes) play a part in the bodies immune system, Platelets(thrombocytes) assist in creating scabs,
The human body is very complex. It is like a job. You have to do a million things in one day to make it through the day. The body uses nine systems to do all of those jobs. They all have separate functions, but some work together. Each system is also made up of organs. There are many ways to care and protect the systems from the many different problems they can have. There are also many interesting facts about each system.
There is two divisions of the bones, the axial skeleton and the appendicular skeleton. The axial skeleton consists of 80 bones which include the skull, vertebral column, ribs and sternum. The skull considts of 22 bones. The cranium which cover the brain are made up of 8 bones and the facial is made up of 14 bones.
