Regulate heat throughout it's body,

Explanation:

Countercurrent Heat Exchange is a normal and varied mechanism in organisms that utilizes parallel pipes of flowing fluid in opposite directions in order to save energy, such as blood flow.

Describe how living conditions change for two tidal organisms
gayaneshka [121]
The shoreline is one of the harshest and most changeable environments for living creatures. The changing tides shift the environment dramatically within a sub-daily cycle. Here, we can consider two typical shoreline organisms, and the changing environment they must endure. Within the rocky shore environment, an octopus would be within the shallow but open sea environment during high tide, and water temperature and salinity conditions would be fairly constant. During low tide, the octopus might become trapped in a rock pool. This environment is dramatically different. The water temperature and salinity might increase drastically with exposure to solar radiation. The octopus is also more vulnerable to predation by humans and other land animals. Within the sandy shore environment, sand clams would be actively positioned at the interface of the sand and water, and will be actively filtering sea water for detritus. During low tide, the sand would be exposed to the air, and the clams would burrow down into the sand so as to avoid dessication.

Blood is a red and slightly viscous liquid that circulates in the blood vessels, propelled by the heart, is essential to the maintenance of life. It transports nutrients, oxygen and hormones to the cells of the body, and rids them of their waste.

Blood circulation helps control body temperature and regulates the volume of certain liquids in the tissues. In addition, the blood carries white blood cells, which defend our body against germs.
