4 basic tissue types?

What is homeostasis?

Maintenance of a relatively stable internal environment.

Most common feedback loop?

Negative feedback.

Rare feedback loop?

Positive feedback.

Example of positive feedback.

Blood clotting.

Example of negative feedback.

Body temperature regulation.

Integumentary, Skeletal, Muscular, Nervous, Endocrine, Cardiovascular, Lymphatic, Respiratory, Digestive, Urinary, Reproductive

11 Organ Systems

Function of integumentary system?

Protection, waterproofing, temperature regulation.

Function of skeletal system?

Support, protection, mineral storage, blood cell formation.

Function of muscular system?

Movement and stability.

Function of nervous system?

Rapid control and communication.

Function of endocrine system?

Hormonal regulation.

Function of cardiovascular system?

Transport blood, oxygen, nutrients.

Function of lymphatic system?

Fluid return and immunity.

Function of respiratory system?

Gas exchange.

Function of digestive system?

Break down food and absorb nutrients.

Function of urinary system?

Remove wastes; regulate fluid/electrolytes.

Function of reproductive system?

Produce offspring.
