Comparing Physiology Worksheet

In this assignment you describe and compare the circulatory, skeletal, and respiratory systems of sharks, iguanas, eagles, and humans. Answer each of the following questions in 25 to 50 words.

Circulatory System

* Shark

* How would you describe the structure and function of this animal’s circulatory system? Include any unique characteristics. A shark’s heart is a two-chambered S-shaped tube, small in proportion to body size located in the head region.

* How does this animal’s circulatory system work?
The blood is pumped by the heart through the afferent bronchial arteries to capillaries in the gills, where the blood is oxygenated). The blood

The glottis is a pair of skin flaps that protects the opening of the trachea (windpipe)

* Eagle

* How would you describe the structure and function of this animal’s respiratory system? Include any unique characteristics.
Eagles have an external naris on both sides of their beak. An eagle's lungs and air sac system are adequate for its size.

* How does this animal’s respiratory system work?
Air moves in through the lungs and on into the air sacs before moving back through the lungs and out again. Air passes through the lungs twice with each breathing cycle - twice that of mammals.

* Human

* How would you describe the structure and function of this animal’s respiratory system? Include any unique characteristics. The primary function of the respiratory system is to supply the blood with oxygen in order for the blood to deliver oxygen to all parts of the body. The respiratory system does this through breathing.

* How does this animal’s respiratory system work?
Oxygen enters the respiratory system through the mouth and the nose. The oxygen then passes through the larynx (where speech sounds are produced) and the trachea which is a tube that enters the chest cavity. In the chest cavity, the trachea splits into two smaller tubes called the bronchi. Each bronchus then divides
