Study Notes
Formed Elements in Blood
- Formed elements include red blood cells, white blood cells, and platelets.
- Organic molecules and salts are not classified as formed elements.
Functions of Blood
- Blood regulates body temperature and defends the body against pathogens.
- It transports oxygen and carbon dioxide but does not manufacture hormones.
Hemoglobin and Oxygen Transport
- Hemoglobin is the pigment responsible for transporting oxygen in erythrocytes.
- Deoxyhemoglobin is the form of hemoglobin without oxygen.
Erythropoietin Production
- Reduced oxygen capacity in blood triggers kidneys to release erythropoietin, stimulating erythrocyte production.
Carbon Dioxide Transportation
- Majority of carbon dioxide produced by cellular respiration is transported by forming carbonic acid in the plasma of red blood cells.
White Blood Cell Types
- Basophils contain blue-stained granules and release histamine to mediate inflammation.
- Lymphocytes include B cells and T cells, providing specific immunity.
- Monocytes are the largest white blood cells without granules and differentiate into macrophages.
- Neutrophils are the most abundant white blood cells, characterized by a multilobed nucleus, and act as first responders to infection.
Platelet Formation
- Platelets are formed from megakaryocytes in the bone marrow.
Blood Clotting Process
- The blood clotting sequence involves prothrombin activator, prothrombin to thrombin, and thrombin converting fibrinogen to fibrin threads.
Blood Type Compatibility
- Individuals with type AB blood can receive blood from type A, B, or O donors.
Homeostasis Functions of Blood
- Blood plays a crucial role in homeostasis, supplying nutrients, gases (oxygen and carbon dioxide), removing waste, and transporting hormones.
Exchange with Interstitial Fluid
- Blood cells exchange oxygen, carbon dioxide, and nutrients with interstitial fluid surrounding body cells.
Antigen and Antibody Composition
- Type B blood has B surface antigens on red blood cells and anti-A antibodies in the plasma.
Facts About White Blood Cells
- White blood cells are produced in red bone marrow but do not transport oxygen and carbon dioxide; they can migrate out of the bloodstream to fight infections.
