Anemia: It is the medical condition characterized by decreased quantity of hemoglobin in the blood. Hemoglobin is the important protein carries oxygen from lungs and supply to various tissues in the body. Anemia occurs when the rate of production of mature cells entering the blood from the red bone marrow does not keep force with […]

Platelets are otherwise called as thrombocytes. The word thrombocytes derived from Greek word “thrombos” meaning a “thick drop” or “clot”, and “cyte” means “cell”. These are very small non nucleated discs, produced from the cytoplasm of megakaryocytes in red bone marrow. Their size is about 2 to 4 µm diameter. Normal range of platelet count

White Blood Cells are otherwise called as Leukocytes. White Blood Cell main function is to protect the body against microbes. They kill the foreign particles by surrounding them and engulf. This is called as phagocytosis mechanism. White Blood Cells are contain nuclei and some have granules in their cytoplasm. Types of white blood cells: Granulocytes:

The circulatory systems is one of the most vital system in the human body. It is responsible for the transportation of blood, oxygen, nutrients, and hormones to all the organs and tissues, while also removing waste products and carbon dioxide. The circulatory system consists of the heart, blood vessels, and blood. The Heart The heart

Introduction: Red Blood Cells are otherwise called erythrocytes. Erythrocyte is derived from the Greek word erythros means ‘red’ and kytos means ‘hollow vessel’. Erythrocytes are circular biconcave nonnucleated discs with a diameter is about 7 microns. RBC is red due to the presence of hemoglobin. Hemoglobin is the protein used to carry oxygen and other

Definition: Blood is one of the transport systems that transport essential nutrients and oxygen to various organs and eliminate carbon dioxide from the body. Blood is composed of platelets, plasma, Red Blood Cells (RBC), and White Blood Cells (WBC). Blood is pumped by the heart through the blood vessels. Blood is used to maintain homeostasis.

Explanation of positive feedback as a regulatory mechanism in homeostasis: The positive feedback mechanism amplifies or enhances the response. In a positive feedback mechanism, the stimulus progressively increases the response, so as long as the stimulus is continued the response is progressively being amplified. Feedback mechanisms like positive and negative feedback play an important role

Introduction to Homeostasis: Understanding the Body’s Balance: The structure of the internal environment keeps up with narrow limits, and this genuinely steady state is called homeostasis. In a real sense, this term implies unchanging, however by and by it portrays, what is happening kept inside narrow limits. At the point when this equilibrium is undermined
