Name an organ system and list as many organs as you can think of that are within that system. Section 1.6 To identify the different organ systems of the human body. To explain what each body system does. To list the different organs in each body system and explain their function. To apply knowledge of the body systems to identify which system a particular disease effects. a) b) c) d) e) f) Body Covering Support and Movement Integration and Coordination Transport Absorption and Excretion Reproduction 1. Integumentary System: Protects underlying tissues Regulates body temp Houses sensory receptors Synthesizes certain products Hair Skin Skin Hair Nails Sweat Glands Sebaceous Glands Hair Skin Nails 1. Skeletal System: Provides framework Protects Provides attachments for muscles Produces blood cells Store inorganic salts (calcium) Joint Bones Cartilage Ligaments Bones Joint 2. Muscular System: Maintains posture Provides body with heat Works together by alternating contracting and relaxing for movement Skeletal muscles 1. Nervous System: Communication via nerve impulses to and from muscles and glands for short periods of time. Brain Brain Spinal Cord Nerves Sensory Organs Spinal cord Nerves 2. Endocrine System: Secretes hormones to affect metabolism of target cells for long periods of time. Hypothalamus Pituitary gland Thyroid gland Parathyroid gland Adrenal gland Pineal gland Thymus Pancreas Ovaries Testes Pineal gland Pituitary gland Thyroid gland Thymus Adrenal gland Pancreas Testis Ovary 1. Cardiovascular System: Heart pumps blood through vessels Blood transports gases, nutrients, wastes, hormones Heart Vessels Heart Arteries Veins Blood Blood vessels 2. Respiratory System - Delivers air to the alveoli where oxygen exchange occurs. - Removes carbon dioxide from the bloodstream. Trachea Pharynx Larynx Bronchi Lungs Nasal cavity Pharynx Larynx Trachea Lung Bronchus 3. Lymphatic System: Defends body against infection with lymphocytes Transports tissue fluid back to blood stream Carries fatty substances from digestive system to blood stream Lymphatic vessels Lymph nodes Thymus Spleen Red bone marrow Thymus Lymphatic vessels Spleen Lymph nodes 1.Digestive System - processes and digests food - absorbs and conserves water - absorbs nutrients - stores energy Teeth Oral cavity Tongue Salivary Glands Esophagus Pharynx Esophagus Liver Stomach intestine Large intestine Liver Gallbladder Pancreas Stomach Small intestine Small Large intestine Rectum 2. Urinary System -Filters the blood - Controls water balance by regulating volume of urine -Regulates blood ion concentrations and pH Kidneys Ureters Urinary Urethra bladder Kidney Ureter Urinary bladder Urethra 1. Reproductive System Male: produces male sex cells and hormones Female: produces female sex cells and hormones, supports embryo development, provides milk for newborn. Male Organs Testes Epididymis Vas deferens Seminal vesicles Prostate gland Penis Scrotum Female Organs Ovaries Uterine tubes Uterus Vagina Labia Mammary glands
