Cells inside lacunae receive oxygen through diffusion from nearby blood vessels. Blood vessels supply oxygen to surrounding tissues, which then diffuse into the lacunae where the cells reside. This process ensures that the cells inside lacunae receive the necessary oxygen for their metabolism.
Bone cells receive their food and oxygen through blood vessels that supply nutrients to the bones. These blood vessels deliver nutrients and oxygen to the bone cells through a process called vascularization.
Nerve cells receive blood and oxygen through a network of small blood vessels called capillaries. These capillaries are located close to nerve cells in order to deliver nutrients and oxygen for their metabolic needs. The brain, for example, has a dense network of capillaries to ensure a constant supply of blood and oxygen to nerve cells.
During a stroke, brain cells do not receive enough oxygen and nutrients due to a blockage or rupture of blood vessels. This lack of oxygen causes the brain cells to die, leading to lasting damage or even death. Immediate medical attention is crucial to minimize the impact of a stroke.
You can get the oxygen you need by breathing in air. The air you breathe contains oxygen that is absorbed by your lungs and then transported by your red blood cells to all the cells in your body. Adequate ventilation, good lung function, and clean air are essential for ensuring you receive enough oxygen.
Oxygen diffuses into cells from the bloodstream due to a concentration gradient, where oxygen is higher in the blood compared to inside the cells. This diffusion occurs passively, moving from an area of higher concentration (blood) to an area of lower concentration (cells), to meet the cell's energy demands for cellular respiration.
Catilage
Lacunae
Osteocytes. These cells are housed within the lacunae of the bone matrix and play a key role in maintaining bone health and structure.
in bones nerve's are found inside the harvesian canal and bone cells are present inside the lacunae surrounding the harvesian system.
Cells in lacunae allow for the exchange of nutrients and waste products with the surrounding extracellular matrix. They also help maintain tissue structure and function by secreting and maintaining the matrix components.
lacunae
The body cells keep you warm.
Sponges get oxygen by taking water through it's pores. The water moves over cells inside the sponge and oxygen in the water moves into the sponge's cells.
In lacunae, you can find chondrocytes. Chondrocytes are cells that are responsible for maintaining the extracellular matrix of cartilage tissue.
Osteocytes
Blood gets oxygen in the cells. This is part of the body system.
Red blood cells carry oxygen to tissue and circulate back to the lungs to receive more oxygen.
