Chapter 1 Diagrams Anatomy & Physiology H

Figure 1. 2 a 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. 2 b 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. 2 c The body’s organ systems. (c) Muscular System. Allows manipulation of the environment, locomotion, and facial expression; maintains posture; produces heat.

Figure 1. 2 d 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. 2 e The body’s organ systems. Glands secrete hormones that regulate processes such as growth, reproduction, and nutrient use (metabolism) by body cells.

Figure 1. 2 f The body’s organ systems. Blood vessels transport blood, which carries oxygen, carbon dioxide, nutrients, wastes, etc. ; the heart pumps blood.

Figure 1. 2 g 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. 2 h 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. 2 i 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. 2 j The body’s organ systems. Eliminates nitrogenous wastes from the body; regulates water, electrolyte, and acid-base balance of the blood.

Figure 1. 2 k 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.

Figure 1. 2 l 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.
