Lymph 11 Systems in the Human Body… Skeletal Endocrine Nervous Digestive Muscular Reproductive Lymph Integumentary Excretory Lymphatic Respiratory Circulatory

11 Systems in the Human Body... Lymph All Working Together...

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

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

All Working Together... The digestive system does not work without the help of other organ systems. The digestive system needs the cardiovascular system to deliver the nutrients to other organs in the body such as the muscles and the brain.

Circulatory System Structure: Heart, blood vessels, and blood Function: Brings oxygen, nutrients, and hormones to cells; fights infections; and regulates body temperature

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

All Working Together... The circulatory system depends on the pulmonary system (lungs) to deliver oxygen to muscles and other organs.

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

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

All Working Together... Muscles and bones work together to produce movement.

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

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

Lymphatic System Lymph Structures: White blood cells, thymus, spleen, lymph nodes, and lymph vessels Function: Help protect the body from disease; collects fluid lost from blood vessels and returns the fluid to the circulatory system

All Working Together... Lymph Getting rid of waste is another necessary function of the body: Lungs get rid of carbon dioxide. Lymphatic vessels recycle extra fluids that build-up next to cells and tissues. Kidneys filter the blood of toxins. Skin releases excess salts through sweat. Lymph

Endocrine System Structures: Hypothalamus, pituitary gland, thyroid, parathyroid, adrenals, pancreas, ovaries (female), and testes (male) Function: Controls growth, development, metabolism and reproduction

Reproductive System Structures: Testes, epididymis, vas deferens, urethra, and penis (males); ovaries, Fallopian tubes, uterus, and vagina (females) Function: Produces reproductive cells, in females, nurtures and protects developing embryo

All Working Together... Reproduction, growth and development are critical functions of all living things. The endocrine system provides the chemical messages for growth, development, and proper functioning of the reproductive system.
