Organ Systems Worksheet 1. Describe the purpose or function of each organ system... Circulatory System: Nervous System: Endocrine System: Excretory System: Digestive System: Respiratory System: Lymphatic System: Reproduction System: 2. 3. Label the indicated organs or structures. 3. Complete the chart using your notes/handouts from the organ systems presentations. Organ Function Associated System Heart Artery Veins -thin walled blood vessel, exchanges gases between the blood and body tissues Circulatory -location of digestion, breaks food down with enzymes Small intestines Alveoli Digestion Produces enzymes that aid with digestion Pharynx Endocrine/digestive Connects the nose Cervix Prostate Ovaries - small, oval-shaped glands on either side of the uterus -produce eggs and hormones Reproduction - oval organs in the scrotum - produce testosterone, and generating sperm Reproduction - produces lymphocytes (white blood cells) - filters damaged/dead red blood cells Lymphatic - temporarily stores liquid waste (urine) Excretory Uterus Urethra Fallopian tubes Lymph vessels Liver Gall bladder Kidneys Large intestines Pituitary gland Adrenal gland Thyroid gland Hypothalamus gland - stimulates secretion of thyroid gland hormone responsible for metabolism Answer each of the following questions regarding the different organ systems: 4. Explain how three structures of the respiratory system work together to accomplish the task of breathing. 5. The circulatory system is a transportation system. Use an analogy of roadways to explain how this system functions. 6. Explain how the excretory system eliminates waste. 7. Explain how each of these organ systems interact: a) Circulatory System and the Respiratory System b) Immune (Lymphatic) System and the Circulatory System c) Excretory System and the Reproductive System d) Nervous System and the Endocrine System e) Nervous System and the Digestive System f) Excretory System and the Circulatory System 8. Some organs have roles in more than 1 system. Explain 2 different functions of each organ and identify the organ systems it plays a part in. a) Brain b) Pancreas c) Bone marrow 9. The endocrine system and the reproductive system are closely linked. Explain why these two systems are dependent on each other.
