Complications?

6. Pericardial cavity Outer covering of the heart
Similar complications as with the lungs

8. Characteristics of Life

Transports blood, oxygen, carbon
dioxide, nutrients and wastes.
The heart is a pump.

17. Lymphatic System
Picks up fluid leaked from blood
Vessels and returns it to blood.
Houses WBC involved in immunity.

18. Respiratory sytem
Keeps blood supplied with oxygen.
Removes carbon dioxide.

19. Digestive System
Breaks food down so body can absorb it.
Elimates indigestable foodstuff
eliminated as feces.

20. Urinary System
Eliminates nitrogenous wastes
From the body.
Regulates water, electrolytes
and acid-base balance.

21. Reproductive System
Testis produce
