What if we didn't have bones? - what would happen
Summary
TLDRThis informative video script delves into the vital role of the human skeleton, emphasizing its importance for movement and protection of organs. It reveals that we start with over 300 bones, which fuse to 206 in adults, and highlights the functions of bone marrow in blood cell production. The script also dispels myths about bones, explaining their living nature composed of collagen and calcium phosphate. Fascinating facts about the largest, smallest, and various types of bones, as well as the significance of joints, are shared to underscore the skeleton's indispensable role in our anatomy.
Takeaways
- 🦴 Skeletons provide a rigid framework that supports and protects our organs, allowing us to maintain an upright posture and move.
- 💪 Bones are living tissues made of collagen for flexibility and calcium phosphate for strength, making them strong and flexible enough to withstand stress.
- 👶 Humans are born with over 300 bones, but as they grow, some bones fuse together, resulting in an adult skeleton of 206 bones.
- 🧬 Bone marrow, found in the hollow centers of many bones, is responsible for producing new red and white blood cells, essential for oxygen distribution and fighting infections.
- 🏆 The largest bone in the human body is the hip bone, which is actually a fusion of six bones.
- 📏 The longest bone is the femur in the thigh, which can account for nearly a quarter of the body's total height.
- 👂 The smallest bone is the stapes, or stirrup bone, in the ear, which is about the size of a grain of rice.
- 👃 The ears and nose do not contain bones but are supported by cartilage, which is lighter and more flexible than bone.
- 🤲 The human hand has 27 bones, and the face has 14, highlighting the complexity of the skeletal system in these areas.
- 🦒 Humans and giraffes have the same number of neck bones, but giraffe vertebrae are significantly longer.
- 🔄 The human body has over 200 movable and semi-movable joints, which facilitate a wide range of movements.
Q & A
What would happen if humans didn't have bones?
-Without bones, humans would be floppy like a bean bag, unable to stand or walk, resulting in a puddle of skin and guts on the floor.
What is the purpose of a skeleton in humans and animals?
-A skeleton serves as a rigid framework that keeps body parts in place and protects organs, allowing for movement through joints connecting the bones.
Are bones considered to be alive?
-Yes, bones are alive, made mostly of collagen for a soft framework and calcium phosphate for strength and hardness.
How do bones stay alive and function?
-Bone cells rely on blood for nutrients, oxygen, and waste removal, similar to other cells in the body.
How many bones do humans have at birth and in adulthood?
-Humans have over 300 bones at birth, but some fuse together as they grow, resulting in 206 bones in adulthood.
What is bone marrow and why is it important?
-Bone marrow is found in the hollow centers of many bones and is responsible for producing new red and white blood cells, essential for oxygen distribution and fighting germs and diseases.
What is the largest bone in the human body?
-The largest bone is the hip bone, which is actually made up of six bones joined firmly together.
What is the longest bone in the human body?
-The longest bone is the femur in the thigh, which accounts for almost one quarter of the body's total height.
Why don't the ears and nose have bones inside them?
-The ears and nose are supported by cartilage, which is lighter and more flexible than bone, allowing them to be bent. Cartilage also rots faster than bone, which is why skulls of skeletons lack nose and ears.
How many bones are in the human hand and face?
-The human hand has 27 bones, and the face has 14 bones.
Do humans and giraffes have the same number of neck bones?
-Yes, humans and giraffes have the same number of neck bones, but giraffe neck vertebrae are significantly longer.
How many movable and semi-movable joints are there in the human body?
-There are over 200 movable and semi-movable joints in the human body.
Why is the skeleton important for the human body?
-The skeleton is crucial for protecting organs and aiding in movement, providing the support structure that keeps us upright and walking.
Outlines
💀 The Importance of Skeletons
This paragraph introduces the vital role of skeletons in the human body. It explains that without bones, humans would be unable to stand or walk and would resemble a floppy beanbag. The script dispels the common misconception that skeletons are scary, emphasizing their supportive and protective functions for our organs. It also highlights that bones are living tissues made of collagen and calcium phosphate, which provide strength and flexibility. The paragraph further explains that bones contain bone marrow, which is responsible for producing blood cells, thus playing a crucial role in our body's ability to function.

Community by suggested by
you what would happen if humans didn't
have bones you'd be floppy like a bean
bag could you stand up forget it could
you walk no way without bones you would
be just a puddle of skin and guts on the
floor skeletons are very intriguing they
have been portrayed as creepy and scary
but they are not really scary in fact
they are very helpful to humans and
animals a skeleton is a rigid framework
without which none of our other body
parts would stay in place if we didn't
have a skeleton under our skin
protecting our organs we would just be a
lump of jelly on the ground everybody
has a skeleton even animals have
skeletons the skeleton is rigid but can
still allow movement because of joints
connecting the bones together are your
bones alive absolutely made mostly of
collagen bone is living growing tissue
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
like other cells in your body the bone
cells rely on blood to keep them alive
blood brings them food and oxygen and
takes away waste how many bones do
humans have when you were born you had
over 300 bones as you grew some of these
bones began to fuse together the result
an adult has only 206 bones what's bone
marrow many bones are Hollow their
holess makes bone strong and light it's
in the center of many bones that bone
marrow makes new red and white blood
cells red blood cells ensure that oxygen
is distributed to all parts of your body
and white blood cells ensure you are
able to fight germs and disease who
would have thought that bones make blood
the skeletal system interesting facts
the largest bone is the B or hip bone in
fact it is made of six bones joined
firmly together the longest bone is the
femur in the thigh tea makes up almost
one qu of the body's total height the
smallest bone is the sturup deep in the
ear it is hardly larger than a grain of
rice the ears and nose do not have bones
inside them their inner supports are
cartilage or gristle which is lighter
and more flexible than bone this is why
the nose and ears can be bent after
death cartilage rots faster than bone
this is why the skulls of skeletons have
no nose or ears the human hand has 27
bones your face has 14 the longest bone
in your body your thigh bone the femur
it's about 1/4 of your height the
smallest is the Stirrup bone in the ear
which can measure 1/10th of an inch did
you know that humans and giraffes have
the same number of bones in their necks
giraffe neck vertebrae are just much
much longer you have over 200 130
movable and semi- movable joints in your
body why do we need a skeleton we need a
skeleton to protect our organs and help
us move by simply using your own body
you can understand that bones and the
skeleton form an important part of
everybody's Anatomy they are the support
structure that keeps us upright and
Walking Tall if this has helped you we
would consider it as a privilege and we
will be thankful if you consider sharing
