Summary Introduction
To explain: The reason behind why nitroglycerin is preferred to relieve chest pain and used to treat heart disease patients.
Concept introduction:
Nitroglycerin is used as a vasodilator that opens blood vessels to improve blood flow. Angina results when there is imbalance between the oxygen supply and oxygen demand without a proportional increase in supply. The process of narrowing of arterioles is known as vasoconstriction. The process of relaxation of arterioles is known as vasodilatation.

1. Insect larvae, such as caterpillars or maggots, grow by shedding their skin in a process
called moulting. When an insect larva moults, it can either become a larger, new larva
or it can turn into a pupa. This process is controlled by hormones, one of which is called
juvenile hormone or JH. High levels of JH cause the larva to become an even bigger larva…
It has beta-2 selective agonist activity.
It does not provide cardiac stimulation with its bronchodilatory effect.
It has lesser cardiac adverse effects as a selective alpha-1 antagonist.
It has a open-piperazine ring which renders it to be less cardiotoxic.

- Each of the following statements briefly describes one of Hb an allosteric interactions. Which of the statements below are false? A drop in the [H+] of blood plasma would lead to a decrease Hb affinity for O₂. An increase in the partial pressure of CO₂ in the tissues would lead to a decrease Hb affinity for O₂- If you inhaled CO for an extended period of time, at partial pressures 1000 fold higher than normal indoor atmospheric pressure, your body would have a difficult time delivering oxygen to your tissues. When the partial pressure of oxygen is low within the atmosphere, your body responds by increasing the biological activity of Hb's negative effectors.arrow_forward24.

- A 19-year-old male is brought into the hospital by ambulance with a 5-day history of vomiting and lethargy. When you begin to talk with the patient you note that he appears disorientated and looks clinically dehydrated. You gain IV access, a routine panel of bloods sent to the lab, and IV fluids started. On observation the patient has an increased respiratory rate, low blood pressure and tachycardia.

Her blood glucose was high, as well as her urine glucose, urine ketones, and serum ketones. Her serum bicarbonate was < 12 mEq/L. Her respiration was exaggerated, and her breath had an acetone odor. Her blood pressure was 90/60 and his pulse weak and rapid (120). 4. What is the acid-base status of this individual? 5. What are the causes of the dyspnea, hypotension, and tachycardia? 6.
