essentially everything else is blocked.
Three substances transported by blood are nutrients, oxygen, and waste from cells.
The respiratory membrane consists of three main structures: the alveolar epithelium, the capillary endothelium, and the fused basement membranes of both. The alveolar epithelium is a thin layer of cells lining the alveoli, while the capillary endothelium forms the inner lining of the pulmonary capillaries. Together, these structures facilitate efficient gas exchange between the air in the alveoli and the blood in the capillaries.
The kidney is divided into many regions. The main sites of reabsorption are the proximal convoluted tubule, the loop of henle and the collecting duct. This is a very basic answer - if you require more detail feel free to PM me.
Any protein, any fat, and most polypeptides.
Epithelial cells form protective barriers in the body, lining organs, cavities, and surfaces. They help to regulate the exchange of molecules and ions between different tissues, and act as a barrier against pathogens and harmful substances. Epithelial cells also play a role in absorption, secretion, and sensation.
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 ;)
Substances that are small, nonpolar, and uncharged will diffuse through a membrane easily. This includes gases like oxygen and carbon dioxide, as well as small lipophilic molecules. Larger or charged molecules may require assistance from transport proteins to cross the membrane.

the three blood vessels are the Veins capillaries Arteries the arteries.
Arteries, Capillaries, and Veins are three kinds of blood vessels.
Capillaries. They are the microscopic tubes that connect the veins and the arteries.
Arteries, veins, capillaries.
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.
Red blood cells, white blood cells, and platelets are typically present in blood but not normally found in urine.
No. There are essentially three different capillaries that differ in the rate of diffusion.
