Organs in the Circulatory System
◦ Heart – pumps blood
◦ Arteries – carry oxygenated blood away from the heart
◦ Veins – take blood back to the heart
◦ Capillaries – carry blood from the arteries to the cells


Common Problems with Circulatory System
◦ Anemia – shortage of red blood cells
◦ Leukemia – form of cancer the effect white blood cells



Group of passages that exchanges gases in order for the body to function properly
Main organ: Lungs take air in and exchange gases with the blood
◦ Blood takes oxygen to the body (inhale)
◦ Then carries away carbon dioxide (exhale)


Problems with Respiratory System
◦ Common cold – effect ability to exchange gases efficiently
◦ Pneumonia- infection of the lungs causing difficulty in breathing
◦ Asthma – passages in the lungs swell and shrink making it difficult to breathe

◦ This system functions as a unit to protect your body and move your body. It also stores substances your body needs


Problems

◦ Bursitis – inflammation of the bursa sac which are located between bones
◦ Arthritis – inflammation of joints
◦ Injuries (fractures, dislocations, sprains)


The group of tissues that makes your body parts move (over 600 muscles)
◦ Muscle Tissue is either voluntary (you control) or involuntary (do not control)


Problems
◦ Strain – overworking of muscle
◦ Cramp – muscle will not relax


Problems
◦ Pinched nerve – when a part of the spine becomes displaced causing a squeeze on a nerve
◦ Infections – polio, rabies
◦ Epilepsy – brain disorder that causes a rapid firing of nerve actions



The glands of the endocrine system secrete hormones to send messages to the cells in the body via the blood
