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
