In This Lesson:
How are cells organized to build the human body?
1. From cells to tissues:
▌Although all cells have things in common but there are many shapes and sizes of cells
Example: ( Muscle cells )
▌They are in the form of long fibers to allow movement.
▌They must be able to store and use energy quickly.
▌They do not work alone, because the size of the muscle cell is very small and must work with thousands of other cells .
2. From tissues to organs:
▌Bundles of tissues are organized to form the muscle.
▌The muscle is considered an organ.
Example: The muscle that lies on the front part of upper arm between the elbow and the shoulder.
3. From organs to systems:
▌There are many organs in the body.
▌Each system is a group of organs that perform a specific function for the body.
Example: (Musculoskeletal system)
The musculoskeletal system is formed of two systems which are muscular system and skeletal system that work together to allow the body movement.
• It consists of a group of organs which are
- Bones. - Muscles. - Ligaments.
- Tendons. - Cartilages.
• Each of these organs has a specific role to allow the
musculoskeletal system to do its function.
4. From systems to the whole body:
• Many of the simple tasks you perform daily require different systems to work together.
Example:
• When you play football, this requires interaction between the respiratory system,
circulatory system, nervous system, musculoskeletal system and excretory system.
Moving Muscles
We will study an example of systems which are the skeletal system and muscular system that work together to allow the movement of your arm towards your shoulder.
• Your arm moves due to contraction and relaxation of muscles connected to the bones of the arm, where:
- The forearm moves up towards your shoulder when
the muscle in front of the upper arm contracts and the muscle in the back of the upper arm relaxes.
- The forearm moves down away from your shoulder
when the muscle in front of the upper arm relaxes and the muscle in the back of the upper arm contracts.
