Intro: an average person has ~5 l of blood, that fluid has a variety of functions transport involved in maintaining fluid balance. 2: defense against pathogens a) immunity, composition of blood, comprised of cells in a fluid (many types of cells) red blood cells a, white blood cells, platelets d) the liquid is called plasma. Plasma (liquid portion of blood) ~55 % of blood . has a yellowish color: the plasma itself is ~92% water, within plasma are inorganic salts in the form of dissolved ions (called blood electrolytes) 1. these salts act as buffers: buffers against ph changes (1) normal blood ph is 7. 4. 2. these salts help osmotic balance: where water is distributed throughout the body. = plasma - fibrinogens: transported blood, nutrients ended up in the circulatory system. Cellular components of the blood: many of the hormones ended up in the circulatory system.
