Study Notes

Multicellular Organisms

Multicellular organisms have five levels of organization: cells, tissues, organs, organ systems, and organisms.
Cells are the basic building blocks.
Tissues are groups of specialized cells working together.
Organs are groups of tissues working together.
Organ systems are groups of organs working together.
Multicellular organisms are increasingly complex.

Plant and Animal Organs

Plants have roots, stems, and leaves.
Animals have organs like the brain, heart, liver, intestines, lungs, stomach, kidneys, bladder.
- Specific functions are given for each organ.

Respiratory System

The respiratory system is involved in breathing in oxygen and breathing out carbon dioxide.
The system has a process of breathing in inhaling and breathing out exhaling.
These processes are performed by muscles between the ribs, and the diaphragm.
Measurements of respiration, and lung volume are possible with equipment such as plastic bottles.

Skeleton

The skeleton supports the body, protects vital organs and helps with movement.
Bones are major parts of the skeleton.
Bone marrow produces blood cells.
Joints allow bones to move.
- Types of joints include hinge and ball-and-socket joints.
- Cartilage protects bones in joints.
- Ligaments connect bones.

Muscles

Muscles work in pairs, antagonistic muscles.
Muscles contract (shorten) to move bones.
Types of muscles include cardiac (heart), smooth, and skeletal muscles.
- Tendons connect muscles to bones.
Muscles contract and relax to create movement.

Breathing

Breathing involves muscles contracting and relaxing.
Inhaling: Muscles between ribs contract, ribs move up and out; diaphragm contracts, chest cavity expands, air rushes in.
Exhaling: Muscles relax, ribs move down and in; diaphragm relaxes, chest cavity shrinks, air forced out.
The composition of inhaled and exhaled air has differences in oxygen and carbon dioxide.

Measuring Lung Volume

Lung volume can be measured using a simple apparatus, like a plastic bottle and tube.
Exhaling into the device effectively shows the volume of air expelled from the lungs.
