Explanation:
Circulatory as the word suggests, circulates throughout the body. Circulatory system is a group of network which consist of blood, blood vessels, and the heart. This network in turn supplies the necessary tissues in the body.
The circulatory system passes through each and every organ and system in the body. Our body cells and the circulatory system are connected in such a way that the transpiration of oxygen is done in an efficient manner. Apart from this, circulatory system also plays an important role in our digestive system.
At the organ level, the circulatory system works to deliver oxygen, nutrients, hormones, and other essential substances to various organs and tissues in the body, while also removing waste products and carbon dioxide.
The process starts with the heart, which acts as a powerful muscular pump. The heart contracts rhythmically to pump oxygenated blood out of the left side of the heart into the main artery called the aorta. From the aorta, the oxygenated blood is distributed to all organs and tissues of the body through a branching network of arteries. Arteries progressively divide into smaller arterioles, ensuring blood supply reaches individual organs.
Once inside the organs, arterioles further divide into microscopic blood vessels called capillaries. Capillaries are crucial in the exchange of oxygen, nutrients, and waste products between the blood and the surrounding cells. Oxygen and nutrients diffuse out of the capillaries into the cells, providing them with the necessary substances for their function and survival. Meanwhile, waste products and carbon dioxide produced by the cells diffuse from the cells into the capillaries, which then carry them away for elimination.
After passing through the capillaries, blood begins its journey back to the heart. Capillaries converge to form venules, which then merge to form larger veins. Veins gradually increase in size and converge into the superior and inferior vena cava, which return deoxygenated blood to the right side of the heart. The right side of the heart pumps this deoxygenated blood to the lungs through the pulmonary arteries, where it gets oxygenated and releases carbon dioxide. Oxygenated blood then returns to the left side of the heart through the pulmonary veins, completing the circulation loop.
This continuous cycle of blood flow ensures that every organ and tissue in the body receives the necessary oxygen and nutrients while waste products are efficiently removed. It is through this complex network of blood vessels and the pumping action of the heart that the circulatory system operates at the organ level, maintaining the overall functioning and health of the body.

B. a naturally occurring, inorganic solid that forms through crystallization of melted materials
C. a naturally occurring organic solid that forms through crystallization of materials dissolved in water
D. a naturally occurring organic solid that has a crystal shape and a definite chemical
I think it's C
Answer:
Option (A)
Explanation:
A mineral is a naturally forming, solid substances that are inorganic in nature. It is comprised of a specific chemical composition, with a proper crystal shape. Various types of minerals are formed by various types of the process such as due to the evaporation, cooling or crystallization of magma. These minerals are combined together and give rise to the formation of rocks. These minerals play an important role in the identification of rocks.
These minerals forming the rocks are found in different geological settings.
Thus, the correct answer is option (A).
