- Helps maintain homeostasis of the body via rapid transmission of electrical system. |
|
|
Term
|
Definition
| Pituitary, thymus, thyroid, parathyroid, adrenal, and pineal glands; ovaries, testes, and pancreas. |
|
|
Term
| Endocrine System Function |
|
Definition
| Helps maintain body homeostasis, promotes growth and development; produces chemical "messengers" (hormones) that travel in the blood to exert their effect(s) on various "target organs" of the body. |
|
|
Term
| Cardiovascular System Organs |
|
Definition
| Heart, blood vessels, and blood. |
|
|
Term
| Cardiovascular System Functions |
|
Definition
- Primarily a transport system that carries blood containing oxygen, carbon dioxide, nutrients, wastes, ions, hormones, and other substances to and from the tissue cells where exchanges are made; blood is propelled through the blood vessels by the pumping action of the heart.
- Antibodies and other protein molecules in the blood protect the body. |
|
|
Term

|
Definition
| Lymphatic vessels, lymph nodes, spleen, thymus, tonsils, and scattered collection of lymphoid tissue. |
|
|
Term
| Lymphatic/Immune System Functions |
|
Definition
- Picks up fluid leaked from the blood vessels and returns it to the blood.
- Cleanses blood of pathogens and other debris.
- Houses lymphocytes that act via the immune response to protect the body from foreign substances. |
|
|
Term
| Respiratory System Organs |
|
Definition
| Nasal passages, pharynx, larynx, trachea, bronchi, and lungs. |
|
|
Term
| Respiratory System Functions |
|
Definition
- Keeps the blood continuously supplied with oxygen while removing carbon dioxide.
- Contributes to the acid-base balance of the blood via its carbonic acid-bicarbonate buffer system. |
|
|
Term
|
Definition
| Oral cavity, esophagus, stomach, small and large intestines, and accessory structures (teeth, salivary glands, liver, and pancreas). |
|
|
Term
| Digestive System Functions |
|
Definition
- Breaks down ingested foods to minute particles, which can be absorbed into the blood for delivery to the body cells.
- Undigested residue removed fromt he body as feces. |
|
|
Term
|
Definition
| Kidneys, ureters, bladder, and urethra. |
|
|
Term
|
Definition
- Rids the body of nitrogen-containing wastes (urea, uric acid, and ammonia), which result from the breakdown of proteins and nucleic acids by body cells.
- Maintains water, electrolyte, and acid-base balance of blood. |
|
|
Term
| Male Reproductive System Organs |
|
Definition
| Testes, prostate, scrotum, penis, and duct system which carries sperm to the body exterior. |
|
|
Term
| Female Reproductive System Organs |
|
Definition
| Ovaries, uterine tubes, uterus, mammary glands, and vagina. |
|
|
Term
| Reproductive System Functions |
|
Definition
- Provides germ cells (sperm or eggs) for perpetuation of the species.
- Female uterus houses the developing fetus until birth; mammary glands provide nutrition for the infant. |
