GAMBAR: THE RESPIRATORY SYSTEM

Fish breathe through their gills. Gills are outfoldings of the body surface that are suspended in the

water. To do this, they have numerous specially adaptive mechanisms. As water passes through the gills,

it passes through several gill arches consisting of many gill filaments (see diagram above). Each gill

filament consists of many flattened out plates called lamellae. The lamella have capillaries, which are

basically really small blood vessels that are so thin that they can absorb oxygen. The blood and water

flow concurrently. That is, in the lamella, the oxygen poor blood flows in an opposite direction to the

oxygen rich water. As the water passes the capillaries in the lamella, the oxygen in the water goes to the

blood. The concurrent arrangement maximizes respiration efficiency.

To keep water flowing into the gills, the fish have specially adaptations. For example, the sharks have to

continually swim with their mouth open to keep water coming through their gills. Some fish are able to

extract water in a stationary position by pumping water in with powerful muscles surrounding the gills.

GAMBAR: THE CIRCULATORY SYSTEM

The circulation of oxygenated blood is essential for the survival of fish. Blood carries oxygen,

nutrients, and waste. To provide the entire fish's body with blood, the heart pumps the blood

throughout the body. The fish's heart has two chambers, the atrium and ventricle. The blood

pumped from the ventricle first goes to the gills where it picks up oxygen and disposed of

carbon dioxide through the thin capillary walls. The oxygenated blood gathers in one central

artery and then goes to the rest of the body and eventually goes back to the atrium. From the

atrium, it goes to the ventricle and the cycle continues. With this system, blood flows relatively

slowly. The muscle contractions of the fish's swimming aids in the movement of blood

throughout the body.

GAMBAR: THE CIRCULATORY SYSTEM

The avian heart has evolved into a large and powerful organ with rapid muscular contractions.

Generally the smaller the species the larger the relative heart size. Generally birds have hearts

larger and ones that beat faster than mammals. The human heart weight amounts to .42

percent of body weight and the pulse rate at rest averages 72 beats per minute. The House

Sparrow's heart constitutes 1.68 percent of the body weight and the pulse rate at rest averages

460 beats per minute. In the Ruby-throated Hummingbird these figures rise to 2.37 percent and

a pulse rate of 615.
