What is diapedisis?
Diapedesis is the process by which white blood cells squeeze through the walls of capillaries and enter tissue spaces to reach sites of inflammation or infection in the body. This is an essential part of the immune response to pathogens.
What is the ability to move through inter-cellular spaces of the capillary walls to the surrounding tissues?
Diapedesis
What causes the fluid part of the blood to be forced through the walls of the capillaries into the space inside the capsule?
This process, known as filtration, is driven by the pressure difference between the blood inside the capillaries (hydrostatic pressure) and the fluid in the tissue spaces outside the capillaries (osmotic pressure). The hydrostatic pressure pushes fluid out of the capillaries, while the osmotic pressure in the tissue spaces helps to prevent excessive fluid loss by drawing fluid back in.
What is the placental barrier made up of?
Chorionic Villi with Fetal capillaries Intervillous Spaces Decidua basalis with maternal capillaries
What is it called when plasma moves out of the capillaries and into the spaces between tissue cells?
chyme
What is the name of the pressure that forces fluids from capillaries into extracellular spaces?
Capillary Hydrostatic Pressure
What are tiny air spaces in the lungs by blood capillaries?
Alveoli. Singular is alveolus.
Why is the blood pressure lower in lung capillaries than body capillaries?
Because if blood pressure in lung capillaries was as high as it is in body capillaries, the hydrostatic pressure caused by this blood pressure would force blood plasma out of the capillaries into intracellular spaces (as is done in body capillaries) or into the alveoli. This would reduce the efficiency of gas exchange.
Why do capillaries have spaces between endothelial cells?
Capillaries have spaces between endothelial cells to allow for the exchange of gases, nutrients, and waste products between the blood and surrounding tissues. This structure, known as intercellular clefts, facilitates the transfer of substances through the capillary wall.
What leaks out of capillaries thin walls?
Capillaries have thin walls that allow for the exchange of various substances between blood and surrounding tissues. As a result, small molecules such as oxygen, nutrients, and waste products can leak out of capillaries. Additionally, fluid may also seep out, which can lead to the formation of interstitial fluid in the tissue spaces. This process is crucial for maintaining tissue health and facilitating cellular functions.
What is the path of lymph from the interstitial spaces to the blood capillaries?
from interstitial spaces towards the heart through lymphatic capillaries to lympahtic vessels then to lymphatic nodes then to the right lymphatic duct once in the venous blood, the lymph is then recycled through the body through the circulatory system
What are interior designers?
An interior designer is someone who plans, researches, coordinates, and manages such projects. An interior designer evaluates and designs interior living and work spaces to make them functional, appealing and well-suited to an owner's needs. Interior designers make interior spaces functional, safe, and beautiful by determining space requirements and selecting decorative items, such as colors, lighting, and materials.
