Hematological changes refer to alterations in the blood's composition, function, or properties, which can be indicative of various physiological or pathological conditions. These changes can affect components such as red blood cells, white blood cells, platelets, and plasma, influencing the body's ability to transport oxygen, fight infections, and maintain hemostasis.

Physiological conditions refer to the normal functioning states of an organism's body systems, which can be influenced by various factors such as genetics, environment, and lifestyle. Understanding these conditions is crucial for identifying deviations that may indicate disease or abnormal health states.

Physiological Conditions

Pathological conditions refer to states of disease or abnormality in the body's structures or functions, resulting from various causes such as genetic defects, infections, or environmental factors. Understanding these conditions is crucial for diagnosis, treatment, and prevention of diseases, as well as for advancing medical research and healthcare practices.

Pathological Conditions

Red blood cells, or erythrocytes, are the most common type of blood cell and are primarily responsible for delivering oxygen from the lungs to the body's tissues and returning carbon dioxide from the tissues back to the lungs. Their biconcave shape and lack of a nucleus allow for maximum surface area and flexibility, optimizing their role in gas exchange and transport within the circulatory system.

Red Blood Cells

White blood cells are crucial components of the immune system, responsible for defending the body against infections and foreign invaders. They originate from the bone marrow and circulate in the blood and lymphatic system, playing various roles in immune response and inflammation.

White Blood Cells

Platelets, also known as thrombocytes, are small blood cells that play a critical role in hemostasis, the process that stops bleeding by forming clots. They are produced in the bone marrow and work by adhering to the site of a blood vessel injury, activating, and aggregating to form a platelet plug while also supporting the coagulation cascade to stabilize the clot.

Platelets

Plasma is a state of matter, distinct from solids, liquids, and gases, characterized by its unique properties such as being electrically conductive and responsive to magnetic fields. It is composed of free electrons and ions and is found naturally in stars, including the sun, and artificially in neon lights and plasma TVs.
