Which of the following occurs a patient with metabolic acidosis (i.e. low blood pH)? Hemoglobin has increased affinity for oxygen. The heme group of hemoglobin is in a ferric (Fe 3+) state. p50 of the O2/Hgb dissociation curve is increased.
The primary function of blood is to deliver oxygen and nutrients to, and remove wastes from, the body cells; but that is only the beginning of the story. The specific functions of blood also include defense, and maintenance of homeostasis, such as distributing heat where it is needed.
1. Link the structure of red blood cells to their functions. 2. Identify the roles of hemoglobin in maintaining homeostasis. 3. Describe the life history of red blood cells. 4. Recognize some common disorders of red blood cells. Prepare Your Materials: Lesson 7.2 PowerPoint® presentation – Found on Instructor Resources, Online Resource
The coronary arteries deliver blood to the muscle cells in the heart. The coronary arteries can become narrowed or blocked by fatty deposits. Suggest how the narrowing of the coronary artery may affect how the heart . functions and how this may affect other body cells.
HUMAN CIRCULATORY SYSTEM QUESTIONS. 1. List the functions of blood in humans. 2. What purpose does haemoglobin serve? 3. What effect do excess amounts of carbon monoxide from cigarettes and car exhausts have on the body? 4. What are the components of blood, and what are their functions? 5. Briefly describe the clotting mechanism of blood. 6.
Blood helps maintain homeostasis by stabilizing pH, temperature, osmotic pressure, and by eliminating excess heat. Blood supports growth by distributing nutrients and hormones, and by removing waste. Red blood cells contain hemoglobin, which binds oxygen. These cells deliver oxygen to the cells and remove carbon dioxide.
