During circulation, oxygen diffuses from the alveoli in the lungs into the blood, while carbon dioxide diffuses from the blood into the alveoli to be exhaled. Nutrients, such as glucose and amino acids, also diffuse from the blood into the tissues, while waste products, like urea, move from the tissues into the blood for excretion. This exchange occurs primarily at the capillary level, where the thin walls facilitate the movement of these substances.

What is the advantage of a double circulation system?
mammals have double circulation which means that during one circulation blood passes twice through the heart. It is necessary because double circulation is important in humans because it keeps oxygenated and deoxygenated blood separate and moreover it circulate blood to organs efficiently.
What is one substance that is found in higher concentrations in the venule than in the arteriole?
Carbon dioxide is one substance that is found in higher concentrations in the venule than in the arteriole. This is because carbon dioxide is produced by cells during metabolism and diffuses from the tissues into the blood, resulting in higher concentrations in the venous circulation.
What function to the valves have related to circulation?
Valves in veins help prevent the backflow of blood during circulation. They ensure blood flows in one direction toward the heart and prevent pooling in the extremities. This mechanism aids in maintaining proper circulation and efficient transport of blood throughout the body.
What are the movement of gasses in and out of the blood?
Gases move in and out of the blood through diffusion. Oxygen from the alveoli in the lungs diffuses into the blood, while carbon dioxide diffuses from the blood into the alveoli to be exhaled. This process is crucial for gas exchange and maintaining the body's pH balance.
What are the three types of circulation?
the three types of Blood Circulation are.Portal circulationPulmonary (Lesser) circulationSystemic (Greater) circulation
Where does oxygen diffuse into the blood during the process of respiration?
Oxygen diffuses into the blood from the air sacs in the lungs during the process of respiration.
What structure diffuses nutrients from the mother's blood into the embryo's blood?
The placenta is the structure that diffuses nutrients from the mother's blood into the embryo's blood. It allows for the exchange of oxygen, nutrients, and waste products between the mother and the fetus during pregnancy.
What diffuses from the kidney back into the blood stream?
Water diffuses from the kidney back into the blood stream.
Where does carbon dioxide diffuse into the blood during the process of respiration?
Carbon dioxide diffuses into the blood in the capillaries surrounding the alveoli in the lungs during the process of respiration.
What gas enters the blood during inspiration?
Oxygen is the gas that enters the blood during inspiration. It is taken into the lungs from the outside air and then diffuses into the blood vessels in the lungs.
The pathway of blood during the pulmonary circulation?
pathway of blood circulatwed by pulomanary
Where oxygen diffuses into red blood cells and carbon dioxide diffuses out?
This process occurs in the capillaries of the lungs. Here, oxygen from inhaled air diffuses into red blood cells in exchange for carbon dioxide, which then diffuses out of the red blood cells and is exhaled from the body.
What Oxygen diffuses into blood from the?
Oxygen diffuses into the blood from the alveoli in the lungs during the process of respiration. This occurs due to the difference in oxygen concentration between the alveoli and the blood in the capillaries surrounding them. The oxygen then binds to hemoglobin in red blood cells for transport to tissues and cells throughout the body.
Where does blood travel to and from during pulmonary circulation?
after it is done with the pulmonary circulation it goes directly to the lungs
What is advantage of double circulation?
advantage of double circulation is that impure & pure blood means de-oxygenated blood & oxygenated blood do not mix together during ciculation.
During ecdysis in snakes what happens to the blood circulation?
During ecdysis the blood circulation is effected due it there may be a blockage between the arteries and veins and it also causes the death of the patient.
Which type of transport is responsible for oxygen entering into the blood?
the answer to apex is passive.
