Spicules are the inorganic, needle-like, calcium carbonate or silicate structures that give a sponge its shape and rigidity.
The organs that form part of the circulatory system are the heart, blood vessels, and blood. The heart pumps blood through the blood vessels, supplying oxygen and nutrients to the body's tissues and removing waste products.
Blood is transported through the body by the circulatory system. This system includes the heart, blood vessels (arteries, veins, and capillaries), and blood itself. The heart pumps blood through the vessels, delivering oxygen and nutrients to cells and removing waste products.
The umbilical cord is responsible for supplying oxygen and nutrients from the mother to the fetus during pregnancy, and for removing waste products from the fetus back to the mother's circulation for processing. It acts as the lifeline connecting the fetus to the placenta.

The heart pumps blood through the circulatory system, supplying oxygen and nutrients to cells and removing waste products. The atria receive blood returning to the heart, while the ventricles pump blood out to the rest of the body. This continuous flow ensures that all cells receive the necessary nutrients and oxygen for their function.
The cardiovascular system. It provides nutrients and oxygen to the entire body and removes waste and carbon dioxide through the circulation of blood. The pumping action of the heart keeps the blood flowing through the vessels and the system pressurized.
Blood is the liquid that carries oxygen, nutrients, and waste throughout the body. It is pumped by the heart through the circulatory system, delivering essential substances to cells and removing metabolic waste products.
The circulatory system is responsible for supplying nutrients and oxygen to the cells. It does this by transporting blood, which carries these essential substances, throughout the body. Blood is pumped by the heart and circulated through blood vessels to deliver oxygen and nutrients to cells and tissues.
It carries carbon dioxide and waste-laden blood from the fetus to the mother through the placenta.
The respiratory system is responsible for supplying oxygen to the cells through breathing in, and removing carbon dioxide from the blood through breathing out. This process occurs in the lungs where gas exchange takes place between the air and blood in the pulmonary capillaries.
Organ systems work together to meet the body's needs by coordinating their functions to maintain homeostasis. Each system has a specific role in supplying nutrients, removing waste, and supporting overall body function. Through communication and collaboration, organ systems like the respiratory, circulatory, digestive, and excretory systems work harmoniously to meet the body's needs for energy, oxygen, and waste removal.
Blood is pumped from the heart to the rest of the body through arteries. It then travels through capillaries, where oxygen and nutrients are exchanged with tissues, before returning to the heart through veins. This process repeats in a continuous loop to supply the body with oxygen and nutrients while also removing waste products.
