Human Body Systems

Organization of The Body The eleven organ systems of the human body work together to maintain homeostasis Homeostasis – process which organisms maintain a relatively stable internal environment

Brain, Spinal cord, peripheral nerves Function: Coordinates the body’s response to changes in its internal and external environments

1) What is the function of the nervous system? A. To respond to stimuli found inside and outside the body. B. To pass oxygen to the cells. C. To exchange oxygen from the lungs to the blood.

2) The nervous system includes which organs A. Brain, Spinal Chord, Heart B. Brain, Spinal Chord, Peripheral nerves C. Brain, Spinal chord, chloroplast

Integumentary System Skin, hair, nails, sweat and oil glands Function: Serves as a barrier against infection and injury; helps to regulate body temperature; provides protection against ultraviolet radiation from the sun

3) Structures: Skin, hair, sweat and oil glands. A. Nervous system B. Integumentary system C. Endocrine system D. Muscular system

Respiratory System Nose, pharynx, larynx, trachea, bronchi, bronchioles, lungs Function: Provides oxygen needed for cellular respiration and remove excess carbon dioxide from the body

4) Structures: nose, pharynx, larynx, trachea, bronchi, bronchioles, lungs A. Muscular system B. Endocrine system C. Lymphatic system D. Respiratory system

5) Function: Provides oxygen for cellular respiration and removes CO2 A. Muscular system B. Nervous system C. Respiratory system D. Digestive system

Digestive System Mouth, pharynx, esophagus, stomach, small and large intestine Function: Converts foods into simpler molecules that can be used by the cells of the body; absorbs food

6)Function: Converts food into simpler molecules that cells can use. A. Reproductive system B. Digestive system C. Excretory system D. Integumentary system

Excretory System Skin, lungs, kidneys, ureters, urinary bladder, urethra Function: Eliminates waste products of metabolism from the body; maintains homeostasis

7) Function: Eliminates waste products of metabolism from the body maintains homeostasis A. Skeletal system B. Muscular system C. Excretory system D. Reproductive system

Skeletal System Bones, cartilage, ligaments, tendons Function: Supports the body; protects internal organs; allows movement; stores mineral reserves; provides a site for blood cell formation

Muscular System Skeletal muscle, smooth muscle, cardiac muscle Function: Works with skeletal system to produce voluntary movement; helps to circulate blood and move food through the digestive system

8) Function: Works with the skeletal system to produce voluntary movement A. Respiratory system B. Endocrine system C. Integumentary system D. Muscular system

Circulatory System Heart, Blood vessels such as the arteries, capillaries and veins, blood Function: Brings oxygen, nutrients, and hormones to cells; fights infection; regulates body temperature

9) Function: Brings oxygen and nutrients to cells A. Circulatory system B. Integumentary system C. Respiratory system D. Muscular system

Hypothalamus, pituitary, thyroid, parathyroids, adrenals, pancreas, ovaries(in females), testes (in males) Function: Controls growth, development, metabolism, and reproduction

10) Structures include: Hypothalamus, pituitary, thyroid. A. Circulatory system B. Respiratory system C. Excretory system D. Endocrine system

Reproductive System Testes, epididymis, vas deferens, urethra, and penis (in males); Ovaries, fallopian tubes, uterus, vagina (in females). Produces reproductive cells; in females, nurtures and protects developing embryo

Lymphatic System White blood cells, thymus, spleen, lymph nodes, lymph vessels Helps protect the body from disease; collects fluid lost from blood vessels and returns the fluid to the circulatory system.
