1. Levels of Body Organization

Key Concepts & Definitions

  • Cellular theory: La teoria cel·lular estableix que les cèl·lules són les estructures mínimes amb vida del cos humà i realitzen totes les funcions vitals.
  • Homeòstasi: L’homeòstasi és el manteniment de l’equilibri en la composició del medi intern de l’organisme per l’activitat coordinada dels sistemes o aparells.

★ Must-know

  • En el cos humà, les cèl·lules s’organitzen en teixits, els teixits formen òrgans i els òrgans coordinats formen sistemes o aparells que contribueixen a mantenir l’homeòstasi.

Further detail

📌 En els organismes pluricel·lulars complexos, les cèl·lules aïllades no poden respondre a totes les necessitats, de manera que s’especialitzen i s’organitzen en estructures amb funcions noves.

What does the cellular theory state about cells?

Cells are the smallest living structures in the human body performing all vital functions.

How are cells organized in the human body?

Cells organize into tissues, which form organs, then systems or apparatuses.

What do coordinated organ systems maintain in the human body?

They maintain homeostasis.

What is homeostasis?

The maintenance of internal environment balance by coordinated systems.

Why do cells in complex multicellular organisms specialize?

Because isolated cells cannot meet all needs alone.

What results from cell specialization in complex organisms?

Cells organize into structures with new functions.
