Answer 1

The 11 major organ systems and their main functions are:

1)The integumentary system supports and protects, regulates body temperature, makes chemicals and hormones, and acts as a sense organ.

2)The skeletal system supports and protects, makes movement easier (with joints and muscles), stores minerals and makes blood cells in the marrow.

3)The muscular system brings about body movement, maintains posture, and produces heat.

4)The nervous system allows a person to communicate with the environment and integrate and controls the body.

5)The endocrine system secretes hormones into the blood that serve to communicate with, integrate, and control mechanisms.

6)The circulatory system transports substances through the body and establishes immunity.

7)The lymphatic system is a subdivision of the circulatory system. It does not contain blood, but rather lymph, which is formed from the fluid surrounding body cells and diffused into lymph vessels. The major functions of the lymphatic system are the movement of fluid and its critical role in the defense mechanism of the body against disease. It also returns excess fluid back to the blood.

8)The respiratory system exchanges oxygen from the air for the waste product carbon dioxide in the blood.

9)The digestive system breaks down food, absorbs nutrients, and excretes solid waste.

10)The urinary system cleans waste products from blood in the form of urine and maintains electrolyte balance, water balance, and acid-base balance.

11)The reproductive system produces sex cells, allows transfer of sex cells and fertilization to occur, permits development and birth of offspring, nourishes offspring, and produces sex hormones.
