Introduction to Medical Sciences Flashcards
What are cells in relation to the organisational system of the body?
The smallest building blocks. They are made of organelles, but they are the smallest units in the building of the body and lots of cells work together to make tissues.
What are tissues in relation to the organisational system of the body?
Tissues are made of cells. Lots of tissues work together to make up organs.
What are organs in relation to the organisational system of the body?
Organs are made of tissues. Organs work together to form systems.
What are systems in relation to the organisational system of the body?
Systems are made up of organs. Systems work together to run the organism (the body) as a whole.
What is the equation of life? Say it out loud, if you can.
Nutrients + Oxygen = Energy (ATP) + waste (including Carbon Dioxide)
Name all of the organ systems.
- Cardiovascular
- Respiratory
- Gastrointestinal
- Renal
- Musculoskeletal
- Immune
- Nervous
- Endocrine
- Reproductive
(There are NINE systems.)
Define tissues.
Groups of cells that share the same characteristics or specializations and perform a function.
Define organs.
Collections of tissues, usually of different types, that synchronise to perform a more complex function.
Describe the Cardiovascular System in simple terms.
The Cardiovascular System delivers OXYGEN and NUTRIENTS to cells, and removes WASTE from cells.
Describe the Respiratory System in simple terms.
The Respiratory System acquires OXYGEN and disposes of CARBON DIOXIDE.
Describe the Gastrointestinal System in simple terms.
The Gastrointestinal System acquires NUTRIENTS and disposes of WASTE.
Describe the Renal System in simple terms.
The Renal System disposes of WASTE.
Describe the Musculoskeletal System in simple terms.
The Musculoskeletal System sources NUTRIENTS, provides MOBILITY to remove organism from danger, and PROTECTS from THREAT.
Describe the Immune System in simple terms.
The Immune System PROTECTS the organism from INFECTION.
Describe the Nervous System in simple terms.
The Nervous System COORDINATES the other systems.
