Circulatory System What is the Circulatory System? The circulatory system involves our heart, lungs, arteries, vena cava, aorta, veins, capillaries and red blood cells. What is the role of the Circulatory System? The role of the circulatory system is to keep us alive by pumping blood around the body. Without any blood; we would be unable to receive oxygen and nutrients, which are carried by our red blood cells to the muscles; therefore, we would not be alive; due to our blood cells not carryin...

This study guide goes through all functions and systems of the body in very deep and explanatory detail.

What is the Respiratory System? The respiratory system; is the system that helps us to breathe. The main organ of this system, the lungs, is located inside of the thorax and is covers by the ribcage and muscular sheets. What is the Role of the Respiratory System? The role of the respiratory system is to take oxygen, for cellular respiration; while taking out wastes such as carbon dioxide. Another role of this system is to keep bring oxygen in, so that cell respiration takes place to give nutr...

What is the Renal System? The renal system, is also known as the uniary system, therefore, the renal system is a part of the two kinds of excretory systems, which rids bodily wastes and fluids. What is the Role of the Renal System? The role of the renal system is to send our blood though a filtration process, in order to cleanse the blood and get out the impurities which are created inside of our bodies. The impurities in the blood stream end up as typical urine, which is stored in our bladde...

What is the Immune System?: The immune system is normally described as a network organised into subsets which regulate, pass information back and forth and protect the whole body from microorganisms. These pathogens carry bacteria that invade and harm the functions of the body. For example, these guards of the body are known as the skin, cells lysozyme, lymphocytes (white blood cells), stomach acid antibiotics and vaccinations. The immune system is one the complicated but amazing systems of the...

What is the Digestive System? The digestive system is a set of organs; which take part in digesting our food and giving us the necessary nutrients. What is the role of the Digestive System? The role of digestion is to break down large molecules of food into its simplest small molecules; so that its nutrients can be absorbed; which helps the whole body to thrive and function.

Circulatory System What is the Circulatory System? The circulatory system involves our heart, lungs, arteries, vena cava, aorta, veins, capillaries and red blood cells. What is the role of the Circulatory System? The role of the circulatory system is to keep us alive by pumping blood around the body.
