The nasopharynx is not directly involved in food transport. It serves as a passageway for air from the nasal cavity to the rest of the respiratory system.
The circulatory system does not open directly to the external environment. It consists of the heart, blood vessels, and blood, and functions to transport nutrients, oxygen, carbon dioxide, and waste products throughout the body.
The circulatory system is a vertebrate organ system that does not open directly to the external environment. It consists of the heart, blood vessels, and blood, and its main function is to transport nutrients, oxygen, hormones, and waste products throughout the body.
The circulatory system or the cardiovascular system. It also transport the waste products of metabolism. The same also transport the oxygen and carbon bi oxide.
The circulatory system, composed of the heart, blood vessels, and blood, is an extensive transport system that transports nutrients, oxygen, hormones, and waste products throughout the body.
pulmonary - lungs -- circulatory helps transport as well.
pulmonary - lungs -- circulatory helps transport as well.
The respiratory system is most directly involved in the transport of oxygen in humans. Oxygen enters the body through the lungs during inhalation and is then transported by the circulatory system via red blood cells to tissues and organs where it is needed for cellular respiration.
Electron transport system
The nasopharynx is not directly involved in food transport. It serves as a passageway for air from the nasal cavity to the rest of the respiratory system.
there is no oxygen present in the electron transport system.
there is no oxygen present in the electron transport system.
The respiratory system is responsible for the intake of oxygen, while the cardiovascular system is responsible for transporting oxygen to tissues via the bloodstream. The circulatory system then delivers oxygen to cells for cellular respiration and removes carbon dioxide waste.
Planaria have a simple transport system that consists of a network of branching gastrovascular canals. These canals distribute nutrients, oxygen, and waste products throughout the organism's body. Nutrients and gases are exchanged directly through the body surface into the surrounding environment.
well oxygen isn't a transport system it is something that can be diffused across the membranes of cells.
the structure of the circulatory system is to transport oxygen to the body
The circulatory system does not open directly to the external environment. It consists of the heart, blood vessels, and blood, and functions to transport nutrients, oxygen, carbon dioxide, and waste products throughout the body.
