Article on Steroids

2008-02-25T10:25:00.000-08:00

The article is about how Barry Bonds getting on steriods. I think he was jealous of McGwire, because he was playing good ball and it was getting to Bonds. Bonds starting making remarks to people saying that McGwire was using juice which is another away of saying steriod. So then Barry Bonds started using steriod hisself to hit more homeruns and get bigger. His personal trainer Anderson provided him with the drugs. The steriods started having their side effects and caused Bonds to blow out his left elbow and he had spent seven weeks on the disabled list. Soon he pulled a groin muscle and was sidelined again.

My response to steriods are bad, because of the way Barry Bonds used them. He is an competitive person, he acts as if he don't want no one that played baseball when he did to get all the attention. He was jealous of McGwire when he was getting all the attention. He shouldnt have let nothing like that get the best of him. He should have already knew someone better than him was going to step in any day. People that use steroids the way Bonds did, dont have no respect for their self treating their body the way they do. They only time someone should use steriods is when the doctor has gave them a presciption for it. Other than that, i think it is bad!!

Reproduce
Respond to environment

All living things have certain things in common
Adaptation to their environment
Growth
Circulation
Sensitive to environment
Reproduction
Cells
The building blocks of life are cells.
All cells in a human are not the same. Please give examples of at least two different types of cells in humans. 1.
Why are cells not the same? b/c they reflect the different functions they serve.
The first person to discover cells was Rober Hooke. He called them cells because they looked like monks' cells called cellula. He first saw cells when he was looking at a piece of cork under a microscope.
The cell theory was created by Theodor Schwann and Matthias Jakob Schleiden.
The three main ideas in the cell theory are
Cells are the basic unit of life
All organisms are made up of one or more cells
All cells arise from pre-existing cells
Unlike animal cells, plant cells contain the organelles _choroplast_ and _______________________________.
All animal cells are covered in a cell __ membranes__. The function of this is to maintains integrity of the cell, controls the passage of materials into and out of the cell, and provides for signal transduction.
The different parts of the cell are known as __organelles__. Each organelle has a specific function. The function of the nucleus is enclosed by a double-layered, porous membrane and contains DNA; the dense core of an atom that is composed of pretons and neutrons. The mitochondria are also known as the ___________________________ of the cell because their function is to release energy from food molecules and transform energy into unable form. Storage is the main function of the _vacuole_.
Bacteria are interesting organisms. Bacterial cells do not have a _membrane_. Instead the chromosomes of the cell are located _necleoid_.
There are different types of transport used in cells as well. _Diffusion_ is the movement of particles from high concentration to low concentration. Osmosis is different than this because it requires _semi-permeable membrane __ and _solute_.
What is the difference between active and passive transport? active transport are cellular energy and passive transport are molecular
What organelle makes the energy used in active transport? osmosis
Is a virus a living cell? no
What is contained inside a virus? RNA and DNA

Review Exercises: Part A:2,4,6,7,11,13, and 14

2. Anatomy deals with the structures of body parts and Physiology considers the functions of these body parts.

4. movement- change in position of the body or of a body part. responsiveness- reaction to a change taking place inside ir ourtside the body. growth- increase in the body size without change in shape. reproduction- production of new organism and new cells. respiration- obtaining oxygen, using oxygen in releasing energy from foods, and removing carbon dioxide. digestion- breakdown of food substances into simpler forms that can be absorbed and used. absorption- passage of substances through membranes and into body fluids. circulation-movement of sunstances from place to place in body fluids. assimilation- changing of absored substances into chemically different forms. excretion- removal of wastes preduced by metabolic reactions.

6. water is the most abundant substance in the body. food refers to substances that provide organisms with necessary chemicals {nutrients} in addition to water. oxygen is a gas that makes up about one-fifth of the air. heat is a form of energy. pressure is an application of force on an object or substance.

11. homeostasis is the consequence of a self-regulating control system that operates by a mechanism called negative feedback.

13. the human organism can be divided into an axial portions, which includes the head, neckm and trunk, and an appendicular portion, which includes the upper and lower limbs.
14. ventral cavity- hollow place within the body including the thoracic, abdominal, and pekvic cavities. and dorsal cavity-a hollow space in the posterior portion of the body containing the cranial cavity and vertebral canal.

(g)(h)flagella- enable sperm cells to move (i)centrosome-nonmembranous structure composed of two rodlike centrioles (j)vesicle-membranous sacs (k-l) microfilaments and microtubes- thin rods and tubules

13.nucleus- cellualr organelle that is enclosed by a double-layered, porous membrane and contains DNA; the dense core of an atom that is composed of protons and neutrons.

14. facilitated diffusion is similar to simple diffusion in that it can move molecules only from regions of higher concentration toward regions of lower concentration.

1.Explain the difference between anatomy and physiology. Anatomy studies the structure that makes up the human body and Physiology studies the funtion of the structures that make up the human body.
2.Please organize the following structures in order from smallest to largest: system, tissue, organ, and cell. cell, tissue, organ, system
3.In the term physiology the suffix -logy means what? study
4.What is the type of membrane that lines all of the passages leading the exterior? Mucous
5.What do you call a mass of cells that all perform the same function?
6.What type of tissue is specialized for the conduction of nerve impulses?
7.The term epidermis contains a prefix and a root term. What is the root in this word and what does it mean? What is the prefix in this word and what does it mean? derm(skin)
8.The term cavity appears frequently in this lesson. What does it mean?
9.Name the four main types of tissue and describe their function. Epithehial-covers the entire surface of the body. Connectives- supports and protects....ie bones, cartilage adipose(fat) Muscle specialized for contractions. Nerve-specialized for the conduction of neural impulse.
10.A cell is made of ____cytoplasm__ except for the nucleus which is made of _protoplasm_.
11.What type of membrane lines joint cavities and outer surfaces of bones? fibrous
12.What is an organ system? interconnected parts that function together.
13.Name the five types of membranes and where each is located. Cutaneous (outer most layer) Mucous (all passageways that lead to the exterior of the body) Fibrous (all joint cavities {the shoulder, knee} also covers the outer surface of bones. Serous ( closed cavities and the organs that are in them)Fascia (superficial fasica and deep fascial)
14.What is the function of the cell membrane? The nucleus?
15.The cutaneous membrane is made of two distinct layers. Name each of these layers and describe what they are made of. Epidermis (outermost layer) and Dermis (corium) compose mainly of connective tissue and microscope organs.
