Even if insects have an open circulatory system, which is usually characterized by slow animals with low metabolic rates, their circulatory system does not participate in supplication of oxygen to the tissues and in the gas exchange process. That is handled by the independent tracheal system, the spiracles, which allows direct contact of cells with the air. With this, the oxygen demand can be supplied even with an open circulatory system.source: http://www.biology-questions-and-answers.com/the-circulatory-system.html
Tigers are mammals and so their circulatory system is very similar to that of humans.
no, a university proffessor would say that a rat is not included in the animals that have circulatory systems at all and they sometimes go 69 with the same sex rats
Tigers are mammals so their circulatory system is very similar to that of the humans. The tigers heart has 4 chambers; there are 2 different heart chambers; one that transports blood and one that receives blood. The ventricles are much larger than the atria and their wide, muscular walls are used to forcefully pump blood from the heart to the body and lungs. Answered By John Thomas
Their circulartion system is very similar to humans (closed circulatory system)
No, mammals have a closed circulatory system as the system consists of veins and arteries, that carry blood through them. Unlike an open circulatory system which also has a heart, but the blood is free flowing throughout the body. For example when you kill an insect, it is like popping a sack filled with blood, which is exactly what insects with open circulatory systems are.
No, mammals have a closed circulatory system
Yes, all insects have internal organs. These organs are different from mammals because they must support different types of systems like the open circulatory system and the ability to breath through the exoskeleton.
circulatory system
The circulatory system found in a goat is the one known as the open circulatory system. This is the common type of circulatory system that you will find in most mammals.
Humans are mammals so yes you idiot!

Rabbits have a closed circulatory system, meaning that their blood flows through a series of vessels and the heart pumps it continuously around the body. This system allows for efficient transport of oxygen, nutrients, and waste products throughout the rabbit's body.
Mammals have a closed Circulatory system. Parts of the system include a heart and veins. It is complex.
Mammals including humans have closed circulatory systems, as do most vertebrates. Some invetebrates also have closed systems. Examples of open circulatory systems are most arthropods, including molluscs and crustaceans and insects.

not all open circulatory systems transport oxygen. Insects have no oxygen in their blood
