introduction Flashcards
1
Q
what is the physiology of (marine) animals?
A
- Regulation of the internal environment
- Circulation of body fluids
- Exchanges and transport of respiratory gases
- Excretion and osmotic balance
2
Q
What is the internal environment?
A
- refers to the conditions and parameters within the body that are tightly regulated to maintain optimal functioning of
- cells
- tissues
- organs
- systems - includes various factors such as
- temperature
- pH
- concentration of ions (e.g. sodium, potassium, calcium)
- concentration of nutrients (e.g. glucose, amino acids)
- concentration of gases (e.g. oxygen, carbon dioxide)
- fluid balance (hydration status)
3
Q
physiological control means?
A
- control is on the internal environment
- body has to activate many organ systems as: circulatory, respiratory and excretory organism
4
Q
what’s the first animal with “blood”? why?
A
- annelids
- they have a closed circulatory system
5
Q
basic process of “respiration”?
A
exchange
6
Q
homeostasis
A
- homeostasis plays a critical role in maintaining the internal environment of the body
- by regulating various physiological parameters
- dynamic maintenance of composition, temperature and pressure of the internal environment
- essential condition for the organism’s survival
