Figure 1.2a The body’s organ systems.
Forms the external body covering; protects deeper tissue from injury; synthesizes vitamin D; location of cutaneous (pain, pressure, etc.) receptors and sweat and oil glands.

Figure 1.2b The body’s organ systems.
Protects and supports body organs; provides a framework the muscles use to cause movement; blood cells are formed within bones; stores minerals.

Figure 1.2c The body’s organ systems. (c) Muscular System.
Allows manipulation of the environment, locomotion, and facial expression; maintains posture; produces heat.

Figure 1.2d The body’s organ systems.
Fast-acting control system of the body; responds to internal and external changes by activating appropriate muscles and glands.

Figure 1.2e The body’s organ systems.
Glands secrete hormones that regulate processes such as growth, reproduction, and nutrient use (metabolism) by body cells.

Figure 1.2f The body’s organ systems.
Blood vessels transport blood, which carries oxygen, carbon dioxide, nutrients, wastes, etc.; the heart pumps blood.

Figure 1.2g The body’s organ systems.
Picks up fluid leaked from blood vessels and returns it to blood; disposes of debris in the lymphatic stream; houses white blood cells involved in immunity.

Figure 1.2h The body’s organ systems.
Keeps blood constantly supplied with oxygen and removes carbon dioxide; the gaseous exchanges occur through the walls of the air sacs of the lungs.

Figure 1.2i The body’s organ systems.
Breaks food down into absorbable units that enter the blood for distribution to body cells; indigestible foodstuffs are eliminated as feces.

Figure 1.2j The body’s organ systems.
Eliminates nitrogenous wastes from the body; regulates water, electrolyte, and acid-base balance of the blood.

Figure 1.2k The body’s organ systems.
Overall function of the reproductive system is production of offspring. Testes produce sperm and male sex hormone; ducts and glands aid in delivery of viable sperm to the female reproductive tract.
![Page 13: Chapter 1 Diagrams](https://reader036.fdocuments.net/reader036/viewer/2022062323/5681665e550346895dd9e537/html5/thumbnails/13.jpg)
Figure 1.2l The body’s organ systems.
Overall function of the reproductive system is production of offspring. Ovaries produce eggs and female sex hormones; remaining structures serve as sites for fertilization and development of the fetus. Mammary glands of female breast produce milk to nourish the newborn.
