What is blood?
What is blood?
The liquid part of blood, composed of plasma and formed elements. Formed elements include red blood cells, white blood cells, and platelets.
What do red blood cells do?
What do red blood cells do?
Red blood cells are responsible for transporting oxygen throughout the body. They contain hemoglobin, a protein that binds to oxygen.
What are white blood cells?
What are white blood cells?
White blood cells are part of the immune system, protecting the body against infections. They can be classified into different types, such as neutrophils, lymphocytes, and monocytes.

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.
