What carries food and air to every body?
What carries food and air to every body?
The circulatory system is responsible for bringing food and oxygen to every cell in your body. The respiratory system is responsible for carrying oxygen and carbon dioxide in and out of your body.
What carries food around the body?
Stomach: An organ with strong muscular walls, the stomach holds the food and mixes it with acid and enzymes that continue to break the food down into a liquid or paste. Small Intestine (Small Bowel): Almost 20 feet long, the small intestine is the workhorse of the digestive system.
What organ system carries oxygen and food around the body?
The circulatory system delivers oxygen and nutrients to cells and takes away wastes. The heart pumps oxygenated and deoxygenated blood on different sides. The types of blood vessels include arteries, capillaries and veins.
What carries oxygen throughout the body?
Inside the air sacs, oxygen moves across paper-thin walls to tiny blood vessels called capillaries and into your blood. A protein called haemoglobin in the red blood cells then carries the oxygen around your body.
How does nutrition carry on its human body?
The circulatory system, which is part of the “cardiovascular” system, is one of the eleven organ systems of the human body. Its main function is to transport nutrients to cells and wastes from cells (Figure 3.4. 1). This system consists of the heart, blood, and blood vessels.
Where do food and air cross over in the body?
The two passages separate again here, in the hypopharynx. Food and liquid pass backward into the esophagus on their way to the stomach. Air passes forward through the larynx and into the trachea, on its way to the lungs. So the lines of travel for air, and for food and liquid, cross over in the oropharynx.
Where does food and liquid pass through the body?
Food and liquid pass backward into the esophagus on their way to the stomach. Air passes forward through the larynx and into the trachea, on its way to the lungs. So the lines of travel for air, and for food and liquid, cross over in the oropharynx. It’s important that air on the one hand, and food and liquid on the other hand,…
How does the respiratory system keep food out of the lungs?
One passageway is for food (the esophagus, pronounced: ih-SAH-fuh-gus, which leads to the stomach) and the other for air. The epiglottis (pronounced: eh-pih-GLAH-tus), a small flap of tissue, covers the air-only passage when we swallow, keeping food and liquid from going into our lungs.
How does tissue fluid carry food and oxygen?
The tissue fluid carries food and oxygen from the blood to the cells, and picks up their waste products like carbon dioxide. After doing its job, most of the tissue fluid seeps back into blood capillaries.
