Internal Organs & Organ Systems

Tissues: 4 Types: Epithelial Muscle Connective Nervous cells similar in shape and function that work together 4 Types: Epithelial Muscle Connective Nervous

Organ: groups of tissues that work together to carry out a particular function Organ system: a group of organs that have related functions Eg: digestive system – esophagus, stomach, small intestine, large intestine, and other associated organs, the liver and pancreas

Major Organs Functions Organ System Major Organs Functions Digestive Esophagus, stomach, intestine, live, pancreas Physical and chemical breakdown of food Circulatory Heart, blood vessels (arteries, veins, capillaries) Transportation of nutrients, gases and wastes: defense against infection Respiratory Lungs, trachea, blood vessels Gas exchange Reproductive Testes, vas deferens, ovaries, uterus, fallopian tubes, glands Sexual reproduction Excretory Kidneys, bladder, ureter, urethra, liver Removal of wastes Locomotion Bones, muscles Movement of body and body parts Endocrine Pancreas, pituitary gland, adrenal glands Coordination and chemical regulation of body activities Nervous Brain, spinal cord, eyes, ears, nose, tongue, peripheral nerves Response to environment; control of body activites

Monitoring Organs: X-rays: high-energy electromagnetic waves absorbed by bone (can also be used with metallic compound to examine internal organs)

CT Scan (“Cat Scan”): many x-rays are taken to reconstruct a 3-D image

Nuclear Imaging: radioactive dye is injected & travels to target organs to allow detailed image of its function

MRI: Magnetic Resonance Imaging uses magnetic forces and radio waves to provide information (very useful for soft tissues)
