The purpose of a circulatory system is to distribute nutrients and oxygen to every cell in the body. As hydras lack a circulatory system such distribution must be accomplished by diffusion along, which is a very slow process and inadequate for anything of any size. So the body form of a hydra is limited in size due to a lack of a circulatory system.
Yes, the circulatory system transports hormones to body tissues. Hormones are released into the bloodstream by endocrine glands and then carried throughout the body by the circulatory system, allowing them to reach target tissues and organs to regulate various physiological processes.
Respiration ! The process by which CO2 is exhaled from the lungs and is replaced by O2
1. Respiratory system 2. Cardiovascular system
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
sponge. Both hydra and sponges are simple aquatic animals that rely on diffusion for nutrient absorption and lack a circulatory system. Nutrients are taken in through their body walls and transported within the body through simple diffusion rather than a dedicated circulatory system.
closed circulatory system (double circulatory system)
closed circulatory system.
The circulatory system
The circulatory system transport oxygen and respiratory material (food) to the billions of our body cells.
The circulatory system is the transportation system of your body.
the heart is part of the circulatory system in the body.
circulatory system
The circulatory system affects the other body systems because the circulatory system gives oxygen to the other system. Without the circulatory system the other systems would not work.
The Lymphatic system acts as "insurance" for the circulatory system.
The circulatory system works with digestive system to circulate the nutrients to all the body parts. The nutrients are digested and absorbed by the digestive system. The circulatory system circulates the nutrients throughout the body.
The circulatory system is dependent on the lungs. The lungs bring oxygen into the body, and the circulatory system transports that oxygen to body tissues.
