It covers the types of blood cells, the process of hematopoiesis where blood cells are produced, and the development and regulation of red blood cells. Red blood cells transport oxygen and carbon dioxide through hemoglobin. Hemoglobin is composed of heme and globin and carries oxygen through various reactions. The life cycle and breakdown of red blood cells is also summarized.
Blood is composed of plasma and formed elements. It transports oxygen, nutrients, wastes, and more throughout the body. Blood also helps regulate pH, temperature, water content, and protects against disease. Blood is made up of red blood cells, white blood cells, platelets, and plasma. Hematopoiesis is the process where blood cells are formed from stem cells in the bone marrow through the influence of growth factors like erythropoietin and thrombopoietin.
Blood (erythrocytes, leukocytes and platelets)Amen Ullah
Blood is a connective tissue composed of formed elements suspended in plasma. It functions to transport oxygen, nutrients, waste, hormones and more throughout the body. Blood is slightly alkaline with a pH between 7.35-7.45. It contains red blood cells which carry oxygen, white blood cells which protect against infection, platelets which help with clotting, and plasma which transports proteins, electrolytes and other substances. The composition and functions of these blood components were described in detail in the document.
This document discusses red blood cells and bleeding disorders. It provides details on the composition and characteristics of blood, the formed elements of blood including erythrocytes (red blood cells), and the process of erythropoiesis (red blood cell development). It also describes the transport and storage of iron in the body, which is essential for hemoglobin formation and red blood cell production. Common blood test values are presented and different types of anemia are classified based on their pathophysiology and morphological features.
1. The document discusses the physical characteristics and components of blood, including plasma, red blood cells, and platelets.
2. Red blood cells transport oxygen and carbon dioxide via hemoglobin and have a lifespan of around 120 days, after which their components are recycled in the liver, spleen, and bone marrow.
3. Plasma is the liquid portion of blood and contains water, proteins, nutrients, waste products, hormones and more. When blood is fractionated, plasma separates from the formed elements of blood.
The cardiovascular system consists of two circuits - the pulmonary circuit and the systemic circuit. Blood alternates between these two circuits. The heart has four chambers - the right and left atria receive blood while the right and left ventricles pump blood out. The heart is surrounded by membranes called the pericardium. It has three layers - the outer epicardium, middle myocardium of cardiac muscle, and inner endocardium. The heart pumps blood through arteries, veins return blood to the heart, and capillaries allow for gas/nutrient exchange.
The cardiovascular system consists of the heart and blood vessels. The heart has four chambers and uses valves to ensure one-way blood flow. It is divided into a pulmonary and systemic circuit.
The heart wall has three layers. It contains cardiac muscle cells that are branched and connected, allowing electrical signals to spread rapidly. The conducting system includes the sinoatrial node, which initiates each heartbeat, and pathways that coordinate ventricular contraction.
An electrocardiogram monitors the heart's electrical activity through different waves. The cardiac cycle involves alternating periods of atrial and ventricular relaxation and contraction. This pumps blood through the heart and vessels in a continuous circuit.
This document provides an overview of the brain and cranial nerves. It begins by introducing the topic and expected learning outcomes. It then describes the major anatomical landmarks of the brain including the cerebrum, cerebellum, and brainstem. It discusses the locations of gray and white matter in the brain. Finally, it covers the embryonic development of the central nervous system and how this relates to adult brain anatomy.
The document discusses the key cellular characteristics of prokaryotic and eukaryotic cells. It describes the typical components of the prokaryotic cell wall including peptidoglycan and outer membranes. The structures of gram positive and gram negative cell walls are compared. Internally, prokaryotes contain a plasma membrane, cytoplasm, ribosomes, and sometimes inclusions like endospores. Eukaryotic cells contain membrane-bound organelles like mitochondria and chloroplasts, as well as membranous networks and cytoskeleton. The processes of endocytosis, exocytosis, and cellular transport mechanisms are also outlined.
