Human musculoskeletal system bone marrow (yellow and red). The yellow marrow has fatty connective tissue and is found in the marrow cavity. During starvation, the body uses the fat in yellow marrow for energy. The red marrow of some bones is an important site for blood cell production, approximately 2.6 million red blood cells per second in order to replace existing cells that have been destroyed by the liver. Here all erythrocytes, platelets, and most leukocytes form in adults. From the red marrow, erythrocytes, platelets, and leukocytes migrate to the blood to do their special tasks. Another function of bones is the storage
Spongy tissue Spongy tissue Spongy tissue is a type of tissue found both in plants and animals. In plants, it is part of the mesophyll, where it forms a layer next to the palisade cells in the leaf. The spongy mesophyll's function is to allow for the interchange of gases (CO2) that are needed for photosynthesis. The spongy mesophyll cells are less likely to go through photosynthesis than those in the palisade mesophyll. It is also the name of a disorder of fruit ripening which can reduce the value of a fruit yield, especially in mango. In the alphonso mango variety, this
