PHYSIOLOGY

Question 1

Levels of Organisation

Answer 1

cells –> tissues [epithelial, muscle, nervous, connective] –> organ –> body system

Question 2

organ structure stomach exaple

Answer 2

stomach
1. epithelial : inner surface (secretion) = lines the stomach and secretes gastric acid + digestive enzymes
2. connective : outside of stomach and maintains structure and organ’s specific arrangement so it stays where it should be
3. muscle : contractions+digestion = mobility and churn food
4. nervous : communication = brain –> stomach for gastric acid production

Question 3

10/11 body systems

Answer 3

1. digestive
2. reproductive
3. endocrine
4. respiratory
5. nervous
6. urinary
7. circulatory
8. integumentary
9. immune
10. musculoskelletal

Question 4

intracellular fluid
interstitual fluid
plasma
extracellular fluid

Answer 4

fluid inside cell –> intracellular fluid
fluid surrounding cells –> interstitual fluid
fluid inside blood –> plasma

plasma + interstitual fluid = extracellular fluid
