Gas exchange or respiration takes place at a respiratory surface-a boundary between the external environment and the interior of the body. For unicellular organisms the respiratory surface is governed by Fick's law, which determines that respiratory surfaces must have: * a large surface area * a thin permeable surface * a moist exchange surface. Many also have a mechanism to maximise the diffusion gradient by replenishing the source and/or sink. Control of respiration is due to rhythmical breathing generated by the phrenic nerve in order to stimulate contraction and relaxation of the diaphragm during inspiration and expiration. Ventilation is controlled by partial pressures of oxygen and carbon dioxide and the concentration of hydrogen ions. The control of respiration can vary in certain circumstances such as during exercise.
What else can I help you with?
Do humans absorb gases?
Yes, humans can absorb gases through the respiratory system when they breathe in gases present in the air. The gases pass through the lungs and are diffused into the bloodstream where they can be transported to different parts of the body.
What happen if oxygen is not transported by the blood to the different parts of the body?
Fairly rapid death.
What two gases are carried with the blood as it goes to the different parts of the body?
nutrient and oxygen
What is the fluid that is carrying gases to the body?
The fluid that carries gases to the body is blood. Oxygen is transported from the lungs to tissues by red blood cells, while carbon dioxide is transported back to the lungs to be exhaled.
Gas is carried mostly by the plasma?
Gas is carried mostly by the plasma in the blood. The plasma contains dissolved gases such as oxygen and carbon dioxide, which are transported to different parts of the body. Oxygen is transported from the lungs to the tissues, while carbon dioxide is carried from the tissues back to the lungs for elimination.
How is the digested food transported?
The nutrients are taken out of the food while it is being digested, and going into your bloodstream, which flows around your body and feeds the nutrients to different parts of your body.
How are nutrients transported to various parts of the body?
Nutrients are transported to various parts of the body through the bloodstream. After digestion, nutrients are absorbed into the bloodstream from the small intestine and then carried to different tissues and organs where they are needed for various functions. The circulatory system, with the help of blood vessels, plays a crucial role in distributing nutrients to all parts of the body.
Why is blood transported all through your body?
To carry oxygen and nutrients all parts of your body. Without it, those parts would die.
What will happen if oxygen is not transported by blood to the different part of the body?
Death of all cells will occur in about 7 seconds.
Why are nutrients transported in the plasma?
Nutrients are transported in the plasma because they need to be carried throughout the body to reach various tissues and organs where they are needed for energy production, growth, and maintenance. The plasma is the fluid component of blood that allows for the efficient circulation of nutrients to different parts of the body.
The gas that is necessary for all life that is transported to all body parts by the blood is?
Oxygen
Why is transport materials essential in living organisms?
Essential materials, such as nutrients and oxygen have to be transported to different parts of the body in living organisms. Without this mechanism, life will not be sustained.
