Answer:
B. Excretory system
Explanation:
<em>Because the excretory system is made to remove urine which consists of waste materials such as excess salts and water. The kidneys are present in it as well. If there is too much water in the body the excretory system will produce urine with higher water concentration so whiteish urine will be produced and if there is a low amount of water in the body the excretory system will produce urine with lower water concentration so yelloish or greenish urine will be produced</em>
Answer:
The circulatory system or vascular system is an organ system that helps in the transport of the blood from and to the heart. The blood transport also takes oxygen, nutrients, hormones, and other components from the heart to the various part of the brain with the help of the arteries and carry waste such as carbon dioxide to the heart in veins.
The oxygenated blood enters in the left atrium and moves to the left ventricle to the aorta and starts its journey to the body whereas deoxygenated blood enters in the right upper chamber or right atrium of the heart and pump to the right lower chamber and to the lungs to carry the oxygen again. This process is a continuous process.
