What to Pack for the San Francisco Weather in July. While most people come packed for warm, sunny days, I recommend coming with a few long sleeved items so you have something to keep you warm as the evenings cool down. For the San Francisco weather in July, I typically wear short sleeved shirts and pants during the day. You could probably bring along some shorts too. Since it's breezy here in July, you will find it a bit too cool most of the time for shorts.
Bone marrow is the soft, flexible connective tissue within bone cavities. A component of the lymphatic system, bone marrow functions primarily to produce blood cells and to store fat. Red marrow contains hematopoietic stem cells that produce two other types of stem cells: myeloid stem cells and lymphoid stem cells. 2  These cells develop into red blood cells, white blood cells, or platelets.
The study recommends that patients get a daily amount of 1.4 to 1.5 grams of protein per kilogram of body weight to help renew and repair the bone marrow. Iron and Bone Marrow Function A key function of bone marrow is to produce red blood cells -- the iron-containing cells that carry oxygen to every part of your body.
