Functions Of Bones In The Body - What Do Bones Do - Bones Support The Body, Provide Protection

In this video we discuss the major functions of bones in the body.

The major functions of bones.

Bones have many functions in the body, in this video we are going to cover the 5 major functions of bones.

Support of the body. Many tissues and organs attach to bones, as do tendons from muscles, so bones provide a rigid framework for the body. This skeletal framework provides the strength to support the body.

Bones provide levers for body movement. Movement is done through muscle contraction, and muscles are attached to bones by tendons. So, a muscle contraction moves a bone, which moves the body part where the bone is located.

Bones provide protection. The brain is protected by the skull, or the bones of the cranium, and the heart is protected by the ribs.

Bones house red bone marrow. Red bone marrow produces red blood cells, which carry oxygen to all parts of the body and remove carbon dioxide, white blood cells, which protect the body from disease and foreign invaders and platelets, which help to prevent bleeding.

Bones are a storage reservoir for calcium and phosphorus. Calcium is important in muscle contraction and in clotting of blood. Having a proper level of calcium in the blood stream is vital for life. When you don’t consume enough calcium from food, it can be taken from bones to increase the amount in the bloodstream. And when you consume more calcium than your body needs, it can be deposited into the bones for later use.

And that be the major functions of bones in the body.

as a first year veterinary student im telling you that was really helpful for me .

My teacher told us to watch this and I really helped me thank you

Nice and short, but I'd also add that they both produce and respond to hormones/proteins. FGF23, lipocalin-2 (which can cross the blood brain barrier)

I have a question related to one of your videos. So carbohydrates provide energy or glucose to the body, but they also contain 4 calories per gram.

I'm confused because I see carbs producing 2 types of energy, glucose and calories.
I also read that energy imbalance is what leads to weight gain.

So why do we generally only take into account being in a caloric deficit to lose fat, when excessive carbohydrates can store fat EVEN on a caloric deficit.

I love that the white blood cells looks like little ghosts lol

Do you know what the two main functions of bones are?
