the of the blood vesses to blood Fla 11. Explain the effects of the nervous and endocrine systems on vasomotion in regulating blood flow. 12. Summarize briefly the effects of hydrostatic pressure, gravity, blood volume, vessel elasticity cardiac output, blood viscosity, and resistance on blood pressure 13. List the factors that interact to regulate arterial blood pressure. Briefly characterize the action of each at the arterial end of a capillary, the blood hydrostatic pressure is 35 mm/Hg, the blood osmotic is 23 mmHg, the tissue hydrostatic pressure is 22 mmHg, and the tissue osmotic pressure is 24 mmHg, determine the net filtration pressure moving materials into the interstitial space. Do 14. If, your work in the space provided below.Explanation / Answer
ANSWER: 11
The physiology of circulatory system of body is under the contol of nervous and endocrine system. These systems control and coordinate the flow of blood in vessels (vasomotion) and blood pumping rate of heart. Both the systems work integratively as in case of low pressure or low vasomotion the CNS of nervous system detect it and send message to activate endocrine system to release some hormones ( e.g. epinephrine or adrenaline and renin from kidney) to increase bloow flow or pressure in blood vessels.
ANSWER: 12
HYDROSTATIC PRESSURE: It is the pressure that acts upon the circulatory vessels (e.g. arteries, veins) when any fluid is passing through them. The normal blood pressure of a healthy adult human is 120/80 mm Hg.
GRAVITY: It is the quantity of force by which any fluid is dropped down the ground under the gravity of earth. The gravity of blood is slightly more than water. VESSEL ELASTICITY: It the define flexibility of arteries and veins, the elasticity of arteries is more than veins and also the flow of blood in the artery is more(120 mm Hg) than veins.
BLOOD VOLUME: An adult humans have 5 to 6 liter of blood in their body, an adequate amount of blood is necessary to proper functioning of vital organs.
CARDIAC OUTPUT: It is the quantity (ml) of blood that pumped out through blood in a minute that represents by the formula:
Cardiac output = Stroke volume × number of heart beat in a minute.
