Document Summary
Blood is important for carrying nutrients, gases, immune cells, cell respiration, protection, etc. Average blood volume in adults is about 5 liters. Hematocrit (the ratio of packed rbcs to total blood volume in a centrifuged sample of blood, expressed in percentages) is about 45% (rbc) of adult blood, and plasma is the remaining 55%. Albumin- osmolality, acts as carrier protein (lack of albumin causes edema) > globulin alpha is involved to inhibit protein degradation. > globulin gamma is used as treatment for hepatitis (liver inflammation) Erythrocytes (rbc) contain hemoglobin, lifespan is about 120 days, originates in bone marrow. Leukocytes (wbc) 2 types: agranular & granular, contain nuclei and mitochondria. Amoeboid ability (can diffuse through capillary walls to reach site of infection). Lymphocytes: immune response- cell attack (t cells) or antibodies (b cells) Asthma is caused by an inflammation of the bronchi (constriction of the bronchi) in the lungs because of higher levels of histamine.
