Front

What is the ventral region of a fish?

Back

The ventral region of a fish is at its belly.

Front

What structure are gill filaments connected to?

Back

Gill filaments are connected to the gill arch.

Front

What type of circulatory pattern do fish have?

Back

Fish have a single circulatory pattern.

Front

How many chambers does a fish's heart have?

Back

A fish's heart has 2 chambers.

Front

What is the location of gas exchange in the gill?

Back

The location of gas exchange in the gill is the lamella.

Front

What is the function of the operculum in fish?

Back

The operculum protects the gills and helps in the movement of water over them.

Front

How does fish blood flow through the cardiovascular system?

Back

Fish blood flows from the heart to the gills, then back to the heart, and then to the body.

Front

What is the main difference between fish and human cardiovascular systems?

Back

Fish have a single circulatory pattern, while humans have a double circulatory pattern.

Front

What is the role of lamellae in fish gills?

Back

Lamellae increase the surface area for gas exchange in fish gills.

Front

What is counter current exchange in fish?

Back

Counter current exchange is a mechanism that maximizes oxygen uptake by having water flow in the opposite direction to blood flow in the gills.
