To determine:
The different types of tissues which makes up the human body’s organ system.
Introduction:
The tissues are the group of cells having similar function and structure. Various types of tissues performs the same function and combine together to form an organ. These organ combines to form an organ system of the body.
Explanation of Solution
The various types of tissues are as follows:
- Epithelial tissue
- Connective tissue
- Muscular tissue
- Nervous tissue
Epithelial Tissue
Epithelial tissue forms the outermost covering of an organ system. It protects the organ system from damage from any external stimuli in the body from various chemical components which are present inside the organ itself.
For example, various acids are present in the stomach which may cause harm to the stomach. Epithelial lining of the stomach prevents the wall of the stomach from getting damaged by the acid. Hence, this tissue has a protective function.
Connective Tissue
As the name suggests, connective tissue connects the various components of the cell. Along with that, various organs are connected to each other with the help of this tissue. Connective tissue comprises of blood. Since blood flows inside the body, various nutrients and minerals are transliterated through it inside the body. This tissue connects the various organs of the body through transportation.
Muscular Tissue
Skeletal muscle - As the name suggests, skeletal muscles are attached to the skeletal. It has stripes and it works voluntarily, which means one can control it with the help of the nervous system.
Cardiac muscle - Cardiac muscle is the heart muscle which are also striated (striped) like skeletal muscle but are not voluntary in nature. Cardiac muscle is involuntary, which means they contract and relax spontaneously.
Smooth muscle - Like cardiac muscle, smooth muscles are also involuntary in nature. However, unlike the cardiac and skeletal muscles, they do not show stripes microscopically. Smooth muscle contributes majorly to the organs more specifically to the hollow bodies.
Nervous Tissue
It comprises of the sensory organs of the body which collects the signals in response to any stimuli. These tissues only generate the reflex in turn to the stimuli as ordered by the nervous system.
Hence, epithelial tissue, connective tissue, nervous tissue, and muscular tissue makes up each of the major organ systems of the human body.

- 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.)

For instance, if you like to drink soda, you might substitute skim milk or water for some of the soft drinks you consumed. List the item you wish to replace with the new item and what you hope to accomplish with that substitution. Be sure to choose foods you know that you'd enjoy and you consider more "healthful." If you feel your diet is already balanced, describe how you accomplish your balanced intake and when you began eating this way.arrow_forwardWhich single food item contained you ate for the 3 days with the most sodium?arrow_forward
- Select a diet and choose one site that provides credible information. Explain why the source itself and/or the information on the site is credible. This should be a report.

In vivo testing provides valuable insight into a drug’s kinetics. Assessing drug kinetics following multiple different routes of administration provides greater insight than just 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: (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 po bioavailability, (f)Fpo absolute ip bioavailability, Fip MAKE SURE ANSWERS HAVE UNITS if appropriate.

- 2. Drug quantification from plasma is commonly performed by using techniques such as HPLC or LC/MS. However, these methods do have limitations, and investigators may choose to use a radiolabeled analog of a drug instead. Radioligands are molecules that contain radioactive isotopes, commonly 3H or 14C. This technique allows investigators to quantify drug concentration from radiation measurements. The following measurements were made in 250 g rats following oral administration of 18.2 µCi of a 14C-labeled drug of interest: Time (min) Plasma Radiation Levels (µCi/L) 0 0.0 2 9.7 4 19.2 7 25.3 9 37.8 12 39.6 14 45.8 17 48.8 20 52.0 25 56.4 30 59.2 35 60.1 40 61.1 45 62.1 50 62.8 60 63.1 70 62.1 80 60.1 90 57.3 100 55.5 110 53.7 120 52.2 150 48.0 180 45.0 240 39.0 Note that a µCi is a measure of the amount of radioactivity and hence is a measure of the amount of drug present. Given that the oral bioavailability of this drug is known to be essentially 100%, estimate the following from this…arrow_forwardThe current nutrition labelling regulation in Hong Kong requires food manufacturer to list E+7 information on the package of pre-packaged food products.
