What else can I help you with?
How does oxygen moves from the respiratory system to the circulatory system?
by diffusion across a capillary wall
Which of the following processes cause substances to move across membranes and doesent require energy ATP?
diffusion or osmosis (diffusion of water)
Describe the exchange of substances across the capillary cell membrane?
Capillary exchange... You have a higher blood pressure and a lower osmotic pressure at the arteriole end of the capillary, this causes water to leave the capillary. The gases oxygen and carbon dioxide and nutrients like glucose and amino acids follow their concentration gradients and diffuse across the capillary membrane. At the venule end of a capillary your blood pressure is less than that of osmotic pressure and water returns to the capillary.Hope this helped. I'm Looking for diagrams of this same thing. Any ideas?Here is a website I found that might help out too.http://www.mhhe.com/biosci/esp/2002_general/Esp/folder_structure/tr/m3/s10/trm3s10_2.htm
What is the process called in which oxygen enters the body and carbon dioxide exits the body?
Oxygen and carbon dioxide travel into and out of the bloodstream via diffusion across alveolar and capillary membranes.
What are the three types of capillary exchange?
The three types of capillary exchange are diffusion, transcytosis, and bulk flow. Diffusion allows for the movement of small molecules like oxygen and carbon dioxide across the capillary walls based on concentration gradients. Transcytosis involves the transport of larger molecules, such as proteins, through endothelial cells via vesicles. Bulk flow refers to the movement of fluids and solutes in response to pressure gradients, primarily occurring through filtration and reabsorption processes.
Do proteins move by diffusion across a capillary into the surrounding tissue?
no you dum bass
Can lipid soluble substance move by diffusion across a capillary into the surrounding tissue?
sure it can
The primary mechanism for exchange of substances across the capillary wall is?
Diffusion
What is the explanation for the process of capillary exchange?
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.
How is diffusion used when cells remove carbon dioxide?
Carbon dioxide moves out of the cells from a higher to lower concentration across the cell membrane. Then the CO2 moves through the capillary wall across the diffusion gradient. The diffusion process is repeated at the capillary/alveolar junction.
How does oxygen moves from the respiratory system to the circulatory system?
by diffusion across a capillary wall
Which transport mechanism causes the respiratory gases to move across the alveolar pulmonary capillary membranes?
Diffusion
What is the pathway of movement for substances traveling across a capillary wall?
Capillaries have very thin walls which are semi-permeable.
Where does oxygen transfer during the transition between the respiratory and circulatory system occur?
By diffusion across a capillary wall.
What causes oxygen to enter and carbon dioxide to leave the capillaries?
Oxygen and carbon dioxide get into and out of cells via diffusion. The gases diffuse across the thin capillary wall, and then diffuse across the cell membrane.
Which process describes the pushing of water across the capillary (blood vessel) membrane?
The process that describes the pushing of water across the capillary membrane is called filtration. Filtration occurs due to the pressure difference between the blood inside the capillary (hydrostatic pressure) and the surrounding tissue (osmotic pressure). This pressure gradient forces water and small solutes to move out of the capillary into the surrounding tissue.
