Respiratory and Circulatory Systems

Other Animal’s Respiration: Sponge, hydra, planaria – diffusion from water Earthworm – skin Insect – spiracles and trachea lead to air sacs Fish – gills

Other Animal’s Circulation: Sponge, hydra, planaria – diffusion Earthworm – aortic arches Insect – dorsal heart Fish – 2-chambered heart Amphibian – 3 chambered heart Reptile and bird – 3+ chambered heart

These systems are interrelated in humans

Anatomy of Our Respiratory System Site of gas exchange

What happens when we breathe?

Problems with Respiration Infection – colds, flu, pneumonia Bronchitis Asthma cancer

Our blood actually takes two paths during circulation

Human Heart circulation Pathway: Enters heart from superior and inferior vena cavae Right atrium Right ventricle Pulmonary arteries To the Lungs 4. Pulmonary veins 5. Left atrium 6. Left Ventricle 7. Aorta To the rest of the body

These are the arteries involved in heart attacks

Components of Blood

Blood Vessels

Problems of the Circulatory System Heart attack Angina High blood pressure (hypertension) Palpitations
