Most rapid rate of absorption and drug response A. Intramuscular B. Rectal C. Subcutaneous D. Inhalation E. Oral

Option A) Intramuscular

Explanation:

A drug is administered directly inside the muscle by means of syringe is most rapidly absorped and stimulating response due to:

- its active form is immediately transported by blood to the target cell where it exerts its function, thus shortening time of travel

- it avoids digestion that could have destroyed some of its potent functional groups

Thus, 'intramuscular' gives the most rapid rate of absorption and drug response

blood enters the heart through two large veins, the inferior and superior vena cava, emptying oxygen-poor blood from the body into the right atrium of the heart. as the ventricle contracts, blood leaves the heart through the pulmonic valve, into the pulmonary artery and to the lungs where it is oxygenated.
