Human Body Systems 7.L.1.4 Summarize the general functions of the major systems of the human body (digestion, respiration, reproduction, circulation, and excretion) and ways that these systems interact with each other to sustain life. __________________ is the maintenance of a stable internal environment in the body. How do you maintain homeostasis? How does your body not maintain homeostasis? Body Organization: ________ __________ _____________ _______________ Organ: Organ System: Summarize the general functions of the following body systems. Cardiovascular System Circulatory System Respiratory System Excretory (Urinary) System Digestive System Reproductive System ______________ Indicate the system by placing an x under the correct column. Circulatory Respiratory Digestive Sperm and egg Gets rid of wastes Breaks down food Transports oxygen and food Removes CO2 and takes in O2 Kidneys, ureters, bladder Capillaries, heart, veins Lungs, bronchioles, alveoli The Muscular System 3 Kinds of Muscle Cardiac muscle Smooth muscle Skeletal muscle The Cardiovascular System What does the cardiovascular system consist of? cardio = vascular = The heart is made mostly of ___________________ tissue. Describe the flow of blood through the heart. Excretory Reproductive 3 types of blood vessels Arteries Capillaries Veins Pulmonary Circulation – Systemic Circulation – What are some cardiovascular problems? The Circulatory System The circulatory system is made up of what? Which organ in the cardiovascular system is part of the circulatory system? Blood – Match the blood part with the correct description: red blood cells, white blood cells, platelets, plasma. ____________carry oxygen ____________liquid part of blood ____________liquid part ____________clotting What is blood pressure? The Respiratory System Label: Nose, Trachea, Bronchus, Alveoli, Lungs; draw diaphragm Describe breathing and cellular respiration. Label the parts of the digestive system: mouth, teeth, esophagus, stomach, pancreas, small intestine, liver, large intestine ____________sharp, begin mechanical ____________absorbs food ____________Tube that leads from mouth; peristalsis ____________Reabsorbs water ____________Begins chemical digestion; churning The Urinary System Excretion – Kidneys – Why are kidneys important? How do the systems work together? Create the effects on a partial multi-flow map of the following situations, indicating what happens to other systems if the situation occurs Kidneys fail Heart does not pump blood Lungs are clogged with smoke Cannot keep food down
