Explanation:
Heart
It is a muscular organ around the size of a closed fist, and it sits in the chest, slightly to the left of center. The heart beats around 100,000 times a day, pumping approximately 8 pints of blood throughout the body 24/7. This delivers oxygen- and nutrient-rich blood to tissues and organs and carries away waste.
Functioning of Heart
The primary function of the heart is to pump blood throughout the body. It supplies oxygen and nutrients to the tissues and removes carbon dioxide and wastes from the blood. It also helps to maintain adequate blood pressure throughout the body.
Blood
blood, fluid that transports oxygen and nutrients to the cells and carries away carbon dioxide and other waste products. ... It is a tissue because it is a collection of similar specialized cells that serve particular functions. These cells are suspended in a liquid matrix (plasma), which makes the blood a fluid.
Answer:
The right side of your heart receives oxygen-poor blood from your veins and pumps it to your lungs, where it picks up oxygen and gets rid of carbon dioxide. The left side of your heart receives oxygen-rich blood from your lungs and pumps it through your arteries to the rest of your body.
