Unit 4 organs and organ systems

Organs and Organ Systems

Tissues are arranged into organs, which serve specific functions:

• Circulatory system (1) pumping and channeling bloodto and from thebodyandlungswithheart,bloodandblood vessels(2).

• Digestive system(3): digestionand processing food.

• Endocrine system (4): communication within the body using hormonesmade byendocrine glands(5).

• Integumentary system(6): skin,hair,fat, andnails.

• Lymphatic system(7): structures involved in the transfer of lymph (8) between tissuesand theblood stream(9), the lymph and the nodes (11) and vesselsthat transport it.

• Immune system(10): defending against disease-causing agents(12).

• Muscular system: movement withmuscles.

• Nervous system: collecting, transferring and processing information withbrain,spinal cord,peripheral nerves (13) and nerves.

• Reproductive system: thesex organs.

• Respiratory system(14): the organs used for breathing.

• Skeletal system: structural support and protection withbones,cartilage,ligaments (15) and tendons(16).

• Urinary system(17): the organs involved in fluid balance, electrolytebalance and excretion ofurine (18).

The body, however, functions as a whole – no system is independent of the others. They work together to maintain the body’s state of internal stability, termed homeostasis (19).
