Water
essentially everything else is blocked.
Three substances transported by blood are nutrients, oxygen, and waste from cells.
Three types of stem cells in adults are hematopoietic stem cells, mesenchymal stem cells, and neural stem cells.
yes
Any protein, any fat, and most polypeptides.
Three substances are water, nitrogen, and access salts.
There are three blood vessels. 1. Arteries - these blood vessells carry blood away from heart to the cells of the body. They have a pulse and they are walled with elastic fibres. 2. Veins - Carry blood from the other parts of the body to the heart. They have valves to stop backward flow of blood. 3. Cappilaries are only one cell thick in reality, and they help to diffuse substances from the blood to the cell through the cell membrane (which is selectively permeable). They diffuse useful substances to the cell, and diffuse waste substances out. Hope that helps ;)
The three substances that can diffuse through a cell membrane are CO2, O2, AND H2O.

the three blood vessels are the Veins capillaries Arteries the arteries.
Arteries, Capillaries, and Veins are three kinds of blood vessels.
Arteries, veins, capillaries.
Capillaries. They are the microscopic tubes that connect the veins and the arteries.
No. There are three types of blood vessels. They are the arteries, veins, and capillaries. Arteries are the largest of the blood vessels. Then comes the veins and the smallest are the capillaries.
In astronomy, diffuse nebulae is the general term for illuminated nebulae. The three types of diffuse nebulae are reflection nebulae, emission nebulae and supernova remnants. They are diffuse as opposed to the non-diffuse dark nebulae, i.e. the particles have spread out.
No. There are essentially three different capillaries that differ in the rate of diffusion.

Nephrons are NOT blood vessels in the kidneys. The nephron is a three-stage unit, located in the kidney, responsible for filtering and absorbing substances. There are about one million of these structures per kidney. # The filter unit is the primary part. Small molecules diffuse into the nephron from the capillaries. # The second stage is the reabsorption region. This is where certain molecules are actively transferred back into the blood. # Finally, the collecting duct transports the waste products to the bladder as urine.
