Answer:
Mechanism that can increase cardiac output :
- Increased cardiac contractility (force)
- Moderate increase in cardiac rate
Effect on blood flow of mitral valve incompetence:
As the mitral valve is present between left atrium and ventricle, its incompetence results in backflow accumulation of the blood in right atrium during ventricular systole and thus resulting in less blood entering the aorta.
Explain the importance/function for each of the following:
a. High elastic fiber content in the aorta : In order to maintain proper pressures,aorta should be able to expand during systole and recoil during diastole. Hence the high elastic fibre in the aorta allows it to do so.
b. Smooth muscle in the arterioles: The flow into the capillaries is controlled allowed by the smooth muscle in arterioles resulting in the contaration of wall of arterioles.
c. Extensive capillaries in the liver and lungs:
Capillaries facilitating the gas exchange in the lungs and also facilitating the removal of waste products from the blood through the action of the liver
d. Valves in the leg veins Differentiate angina from myocardial infarction with regard to its cause and the characteristics of pain associated with it:
Valves will prevent the pooling of blood in the lower extremities due to gravity and facilitate the constant steady flow to the heart.
If you had a client with persistent chest pain following rest and administration of nitroglycerin, We would<u> Call for assistance and transport the person to the hospital. Treat as for shock, and give oxygen if available</u>.
Well, it already has the antibodies in its system and so it just uses those
Answer:
Fermentation:
Fermentation may be defined as the process of conversion of sugar into alcohol and carbon dioxide with the help of microorganisms. This process mainly occurs in the limited supply of oxygen. This is mainly an extracellular process.
Anaerobic respiration:
Anaerobic respiration may be defined as the process of a cellular respiration of an organism. This process mainly occurs in the complete absence of the oxygen. The anaerobic respiration is completely an intracellular process.
You didnt list the rest of the question. atleast I dont think. but, photosynthesis is a process used by plants and other organisms to convert light energy normally from the Sun into chemical energy that can later be released to fuel the organisms. so anything that feeds itself just by using sunlight is bc of photosynthesis. and thats manily plants & flowers
Answer:
Synthetic polypeptides consist of a repeating sequence of certain amino acids and their primary structures are not as complicated as those in proteins. The polypeptides are very important polymers in both polymer and protein science.
