Questions And 100% Correct Answers.
2 Types of circulatory systems - Answer 1. Open
2. Closed
Circulatory systems have 3 major parts: - Answer 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... - Answer Hemocoel
7 Major Functions of the Vertebrate Circulatory System - Answer 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)

The pumping action of the 4 CHAMBERED HEART makes up a... - Answer Cardiac cycle
The cardiac cycle is the alternating ________________ and ___________________ of the heart
chambers - Answer Contraction; Relaxation
Cardiac Cycle - Answer 1. The 2 atria contract pumping blood into the ventricles
2. A fraction of a second later, Systole
3. Diastole
Systole - Answer When the 2 ventricles contract and force blood into the arteries
Diastole - Answer When both chambers relax briefly
Blood pressure is shown by ______________ pressure over _______________ pressure. -
