the cocoon.
The liquid was pulled into the small tube by capillary action.
Internal Respiration."Internal respiration is the diffusion of gases between blood and interstitial fluid across the endothelial cells of capillary walls."Says my Anatomy Book.
Capillary in the villi are used to absorb the digested food and transport the food the the destination cell.
Endothelial cells are adapted to carry out their function of forming a barrier between blood and surrounding tissues by having tight junctions that prevent leakage, expressing adhesion molecules for cell communication and immune response, and having a selective permeability to allow for transport of nutrients and waste products. Additionally, they can regulate blood flow and vessel tone by producing vasoactive substances.
Capillaries are extremely small blood vessels. The capillaries transport blood from the arteries to the veins in the human body.
Capillary exchange is the process by which substances, such as oxygen and nutrients, are exchanged between the blood in capillaries and the surrounding tissues. This occurs through diffusion, facilitated diffusion, and active transport. The exchange is driven by a concentration gradient and the movement of substances across the capillary wall is regulated by small pores called fenestrations and by the presence of transport proteins.
Capillary transport mechanisms refer to the movement of fluids through capillaries by processes such as diffusion, filtration, and osmosis. These mechanisms help to transport nutrients, gases, and waste products to and from cells in the body. The exchange of substances across capillaries is essential for maintaining proper tissue function.
Diffusion
Neither except in the case of the sodium potassium pump. Transport of "molecules" is by osmotic pressure at the capillary bed and by and concentration gradient/ diffusion at the actual cell membranes.
The process is capillary action. The part is the xylem
The stem is to transport water and food to the ovule of the flower for reproduction
