Step by step
Solved in 3 steps
- Develop a model for the flow rate (amount per unit time) of blood through a given blood vessel. (Hint: which factors are important; do they increase or decrease the rate?)A pharmaceutical company develops an artificial red blood cell that is very effective at transporting oxygen but unable to transport carbon dioxide. Explain what would happen in the blood vessels if this substance were used in a blood transfusion. How would this affect the recipient (Assume the transfusion has no effect on the level of plasma in the blood)?Predict the significance of slow blood flow in the capillaries
- PREDICT THE EFFECTS OF A DRUG THAT BLOCKS THE SYMPATHETIC NERVOUS SYSTEM ON BLOOD PRESSURE AND HEART RATE.How would this drug affect the three factors that determine blood pressure?Answer each question with a type of blood vessel: [1] artery; [2] vein; [3] capillary. (a) Which type of blood vessel carries blood from the tissues to the heart? (b) Which type carries blood that is rich in oxygen? (c) Which type contains a thin cell wall that allows the passage of water and small molecules?Explain counting the pulse is counting the rate of heart beat.
- Write a note on “Regulation of cardiac activity”?Write a detailed account of how the body monitors blood pressure with baroreceptors and how the autonomic nervous system responds to maintain blood pressure by altering the heart rate and blood vessels.Emphasize the importance of the arterial baroreceptor reflex?
