Chapter 1 Diagrams

Anatomy & Physiology H


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.


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.
