It primary function is to supply cells with the oxygen and nutrients they require to live as well as to remove toxic waste products. Another function is to signal cells to act in a particualr way by carrying hormones. Finally it is also used to redistribute heat around the body.
The main organ of the circulatory system is the heart.
CPR focus is respiratory and circulatory systems.
The root system of the Jowar plant can be divided into a primary and secondary root system. The primary system has a primary root that develops from the germinating seedling and provides the seedling with water and nutrients required for growth. The primary root is short-lived, and the function of the primary root is taken over by a secondary root system. The secondary system develops from the root crowns that are located just under or above the soil. The root system of an adult Jowar plant is made of secondary adventitious roots. Lateral roots develop from the secondary adventitious roots and penetrate the soil in all directions.
The nervous system.
no
the circulatory system is the way it keeps your heart pumping
Lymphatic System
transport
3.cells in the nervous system are different in structure from cells in the circulatory system and they carry out different specialized functions
Help please!! :( right now PLEASE
Poriferans do not have distinct circulatory system. Instead water flow system support all these functions like circulatory, respiratory, excretory etc.
circulatory system
The word circulatory is the key word. The circulatory system circulates blood throughout the body.
heart arteries veins
The main organ of the circulatory system is the heart.
The three functions of the blood when the circulatory system is working with the respiratory system are to take in needed gases from the lungs, expel waste gases from the tissues, and carry hormonal messages that communicate the body's needs to the respiratory adn circulatory systems.
major functions:Arteries,Veins,Capillaries
