2 Types of circulatory systems - ANSWERS-1. Open
2. Closed
Circulatory systems have 3 major parts: - ANSWERS-1. A fluid that
circulates (blood)
2. A channel (vessels) that the fluid circulates through
3. A pump (heart) to keep the fluid moving
In the open circulatory system, part of the "channel" that the fluid
circulates through is an open space called the... - ANSWERS-
Hemocoel
7 Major Functions of the Vertebrate Circulatory System - ANSWERS-
1. Transport of oxygen to the tissues
2. Transport of the nutrients to the tissue
3. Transport of waste from the tissues
4. Distribution of hormones
5. Regulation of body temperature (homeostasis)
6. Prevention of blood loss (clotting)
7. Protection from invaders (immune system)
