Summary Introduction

To determine:

The functions of the respiratory system in addition to gas exchange.

Introduction:

The respiratory system obtains oxygen from the atmosphere, by the process of respiration. The gaseous exchange occurs in the lungs in which the oxygen is inhaled, and carbon dioxide is exhaled. There are various parts of the respiratory system, such as the nose, mouth, pharynx, larynx, trachea, bronchi, and lungs.

Explanation of Solution

The function of the respiratory system are as follows:

Gas exchange:

Oxygen enters the blood, and carbon dioxide leaves.

Regulation of blood pH:

pH is regulated by changing the blood carbon dioxide levels.

Voice production:

Movement of air past vocal folds make sound and speech.

Olfaction:

The smell is observed when airborne molecules enter the nasal cavity.

Protection:

It protects against the microorganisms by preventing their entry.

Outline a method for using apomixis to maintain feminized CannabisAssume apomixis is controlled by a single dominant gene. You can choose the type of apomixis: obligate or facultative, gametophytic or sporophytic. Discuss advantages and disadvantages of your proposed method.
Kinetics: One-Compartment First-Order Absorption 1. In vivo testing provides valuable insight into a drug’s kinetics. Assessing drug kinetics following multiple routes of administration provides greater insight than a single route of administration alone. The following data was collected in 250-g rats following bolus IV, oral (PO), and intraperitoneal (ip) administration.  Using this data and set of graphs, determine:(calculate for each variable) (a) k, C0, V, and AUC* for the bolus iv data  (b) k, ka, B1, and AUC* for the po data  c) k, ka, B1, and AUC* for the ip data  (d) relative bioavailability for po vs ip, Fpo/Fip  (e)absolute ip bioavailability, Fip  (f) absolute po bioavailability, Fpo
3. A promising new drug is being evaluated in human trials. Based on preliminary human tests, this drug is most effective when plasma levels exceed 30 mg/L.  Measurements from preliminary tests indicate the following human pharmacokinetic parameter values:  t1/2,elim = 4.6hr, t1/2,abs = 0.34hr, VD = 0.29 L/kg, Foral = 72%.  Based on these parameters, estimate the following if a 49 kg woman were to receive a 1000mg oral dose of this drug: (a) Estimate the plasma concentration of the drug at 1hr, 6 hr, and 20hr after taking the drug ( Concentration estimate) (b) Estimate the time for maximum plasma concentration (tmax).  (c) Estimate the maximum plasma concentration (Cmax).  (d) Estimate the time at which the plasma level first rises above 30 mg/L.  (Note this is a trial and error problem where you must guess a time, plug it into the concentration equation, and determine if it is close to 30 mg/L.  Hint:  based on part (a) it should be apparent that the answer is less than 1hr.)  (e)…
