Which is the weakest bone in human body?
Lacrimal boneThe lacrimal bone is perhaps the most fragile bone of the face and one of the smallest bones in the body.
Spanning between the middle of each eye socket, each lacrimal is thin and scalelike and serves as support for the eye..
What is the main function of blood?
Blood has many different functions, including: transporting oxygen and nutrients to the lungs and tissues. forming blood clots to prevent excess blood loss. carrying cells and antibodies that fight infection.

What is bone and types?
The four principal types of bones are long, short, flat and irregular. Bones that are longer than they are wide are called long bones. They consist of a long shaft with two bulky ends or extremities. They are primarily compact bone but may have a large amount of spongy bone at the ends or extremities.
Do bones produce blood cells?
Red blood cells are formed in the red bone marrow of bones. Stem cells in the red bone marrow called hemocytoblasts give rise to all of the formed elements in blood. If a hemocytoblast commits to becoming a cell called a proerythroblast, it will develop into a new red blood cell.
How do we classify bones?
Bones can be classified according to their shapes. Long bones, such as the femur, are longer than they are wide. Short bones, such as the carpals, are approximately equal in length, width, and thickness. Flat bones are thin, but are often curved, such as the ribs.
Are teeth bones?
Are Teeth Considered Bones? Teeth and bones look similar and share some commonalities, including being the hardest substances in your body. But teeth aren’t actually bone. This misconception might arise from the fact that both contain calcium.
What are the two types of bone tissue?
There are two types of bone tissue: compact and spongy. The names imply that the two types differ in density, or how tightly the tissue is packed together. There are three types of cells that contribute to bone homeostasis.
Which is made by bone?
Collagen is a protein that provides a soft framework, and calcium phosphate is a mineral that adds strength and hardens the framework. This combination of collagen and calcium makes bone strong and flexible enough to withstand stress. More than 99 percent of the body’s calcium is contained in the bones and teeth.
Is hematopoiesis a function of bone?
Red bone marrow is involved in hematopoiesis. This is another name for blood cell production. Hematopoietic stem cells that are found in red bone marrow can develop into a variety of different blood cells, including: Red blood cells.
What are the 6 functions of bone?
The human skeleton performs six major functions: support, movement, protection, production of blood cells, storage of minerals, and endocrine regulation.
What is the function of bones in our body?
Bones provide support for our bodies and help form our shape. Although they’re very light, bones are strong enough to support our entire weight. Bones also protect the body’s organs.
Which is the strongest bone in our body?
femur boneThe femur bone is the longest and strongest bone in the body. Located in the thigh, it spans the hip and knee joints and helps maintain upright posture by supporting the skeleton.
What are the functions of bones and muscles?
The bones of the skeletal system protect the body’s internal organs, support the weight of the body, and serve as the main storage system for calcium and phosphorus. The muscles of the muscular system keep bones in place; they assist with movement by contracting and pulling on the bones.
What is the softest bone in the body?

What is bone and its function?
The major functions of the bones are body support, facilitation of movement, protection of internal organs, storage of minerals and fat, and hematopoiesis. Together, the muscular system and skeletal system are known as the musculoskeletal system.
What is the function of bone quizlet?
The first basic function for the skeletal system and its bones is support. Bones serve as a framework to which the other organs and tissues of the body are attached. The framework of your skeleton provides the strength for your body. To uphold and support your body, your bones have to be strong.
What is hardest bone in human body?
The hardest bone in the human body is the jawbone. The human skeleton renews once in every three months.
Where is bone found?
Long bones are mostly located in the appendicular skeleton and include bones in the lower limbs (the tibia, fibula, femur, metatarsals, and phalanges) and bones in the upper limbs (the humerus, radius, ulna, metacarpals, and phalanges).
What are the functions of muscles?
The muscular system is composed of specialized cells called muscle fibers. Their predominant function is contractibility. Muscles, attached to bones or internal organs and blood vessels, are responsible for movement. Nearly all movement in the body is the result of muscle contraction.
