What determines in which direction carbon dioxide and oxygen will diffuse in the lungs and tissues?

Diffusion, whether of gases or some other substance, is always dependent on a diffusion gradient. Diffusion always occurs from an area of high [H] concentration to an area of low [L] concentration.
In the case of the lungs:
- oxygen moves from a [H] concentration in the lungs/alveoli to a [L] concentration in the blood
- carbon dioxide moves from [H] concentration in the blood to a [L] concentration in the lungs/alveoli
With tissues, the situation is much the same:
- oxygen moves from a [H] concentration in the blood to a [L] concentration in the tissues
- carbon dioxide moves from a [H] concentration in the tissues to a [L] concentration in the blood

What tissue type is most involved in regulating and controlling body functions?
The endocrine system controls and coordinates body activities and it is made up of ductless glands and some diffuse tissues. Diffuse tissues are cells within organs and tissues that secrete hormones. So, the answer would have to be glandular tissue and diffuse tissue.
How do epithelial tissues receive nutrients?
Nutrients diffuse to epithelium from underlying connective tissues, which have abundant blood vessels.
Why does carbon dioxide moves into red blood cells by diffusion rather than by active transport?
Do you mean why does carbon dioxide diffuse out of the cells into the bloodstream? Diffusion is the movement of particles from a region of high concentration to a region of low concentration. Carbon dioxide is present in your body cells at a high concentration because the cells are making it. The process which makes carbon dioxide in cells is respiration. This is the release of energy from food. Carbon dioxide is a waste product of respiration. The carbon dioxide molecules diffuse into the blood because there is a lower concentration in the than in the cells. This is because the blood is always moving, so the carbon dioxide is carried away and does not build up. The difference in concentration between the cells and the blood keeps carbon dioxide diffusing in the correct direction.

What is an example of molecules that diffuses into a cell?
water
How does the circulatory system get oxygen and sugar to all the cells in the body?
When blood passes through the lungs, oxygen from the alveoli diffuse into the capillaries and is taken up by red blood cells. There it binds to hemoglobin. The red blood cells will travel through the arteries to the tissues where the oxygen will disassociate itself from the hemoglobin and diffuse into the tissues (cells).
What gas diffuse from the tissues to the blood?
Both oxygen and carbon dioxide diffuse from body tissues into the blood.
What gas diffuses from the tissues to the blood?
Both oxygen and carbon dioxide diffuse from body tissues into the blood.
How do you resive oxygen and remove carbon dioxide?
Oxygen and carbon dioxide are moved to and from body tissues via the circulatory system. These materials diffuse through the cell membrane, and then diffuse through the capillary wall into or out of the bloodstream.
What are the long term effects of increased oxygen diffusion rate?
An increase in diffusion rates in tissues favours oxygen movement from the capillaries to the tissues, and carbon dioxide from the cells to the blood. Also With some training these rates increase, allowing oxygen and carbon dioxide to diffuse more rapidly.
How does long term exercise affect oxygen diffusion rates?
An increase in diffusion rates in tissues favours oxygen movement from the capillaries to the tissues, and carbon dioxide from the cells to the blood. Also With some training these rates increase, allowing oxygen and carbon dioxide to diffuse more rapidly.
What determines whether oxygen and carbon dioxide diffuse into or out of the capillaries of the tissues near alveoli explain?
its the blood which act as a transporter and the concentration of blood determines that oxygen will diffuse faster than carbon dioxide due to its small molecular weight but if diffusion occur in such manner then amount of carbon dioxide will be automatically more. carbon dioxide is a toxic gas and its presence in more amount can causes problems by increasing the PH of blood,but carbon dioxide has an affinity for water. The excess carbon dioxide gets dissolve in water or simply we can say in plasma of blood more than oxygen so its its excrete in lungs and passes from lungs to mouth in atmosphere following bronchioles and bronchi.
How oxygen and carbon dioxide enter and leave cells?
carbon dioxide goes into pores in the under surface of the leaf, called stomata, and diffuse into the leafs tissues and oxygen exits through these pores aswell though this cannot happen when the stomata close up
The vessels in the circulatory system that allow molecules to diffuse across tissues?
because they have a long tissues that the blood flows
Describe how chemicals are exchanged between cells and blood?
Chemicals are exchanged between cells and blood through processes such as diffusion and active transport. Oxygen and nutrients are transported from the blood to the cells, while waste products and carbon dioxide are transported from the cells to the blood. This exchange occurs across the walls of capillaries, which have thin walls that allow for efficient diffusion of molecules between the blood and cells.
What happens to carbon dioxide when it leaves the tissues?
It is released
What tissue type is most involved in regulating and controlling body functions?

Carbon dioxide accumulates in cells and tissues?
the pH will decrease.
