6. Describe the life cycle of a red blood cell. Red blood cell is made through bone marrow then is carried through the blood stream and travels through the organs then another sensor tells that more needs to be made.
10. List two sources of iron that can be used for the synthesis of hemoglobin. absorbed from small intestine; conserved during red blood cell destruction and made available for reuse.
14. Describe a blood platelet, and explain its functions. they are not complete cells. they arise from very large cells in the red bone marrow, called megakaryocytes, that fragment a little like a shattered plate, releasing small sections of cytoplasm--platelets-- into the circulation.

Valves are located between the right atrium and the right ventricles.ects.
6. Trace the path of the blood through the heart. blood enters through atria and goes through the right ventricle then moves through the pulmonary valve and into the capillaries and goes through pulmonary veins and heads out through the left atrium then last they go through the left ventricle.
10. Explain the origin of heart sounds. the sounds are due to vibrations in the heart tissue produced as the blood flow is suddenly speeded or slowed with the contraction and relaxation of the heart chambers, with the opening and closing valves.
19. Describe the structure and function of capillary. Single layer of squamous epithelium. Function: provides a membrane through which nutrients, gases, and wastes are exchanged between the blood and tissue fluid.

22. Compare the mechanisms of coughing and sneezing, and explain the function of each. coughing: deep breath is taken, glottis is closed, and air is forced against the closure; suddenly the glottis is opened, and a blastof air passes upward. Function- clears lower respiratory passages. sneezing: same as coughing, except air moving upward id directed into the nasal cavity by depressing the uvula. Function- clears upper respiratory passages.

Function- clears lower respiratory passages. sneezing: same as coughing, except air moving upward id directed into the nasal cavity by depressing the uvula. Function- clears upper respiratory passages.
23.Explain the function of yawning. ventilates a larger proportion of the aveoli and aids oxygenation of the blood.
31. Define hyperventilation, and explain how it affects the respiratory center. breathing that is abnormally deep and prolonged.
35. Describe how oxygen is transported in blood. oxygen combines with iron atoms of hemoglobin molecules.
36. List three factors that increase release of oxygen from the blood. Increases temperature, increase carbon dioxide, and increases the release of oxygen as the ph blood decreases.

Article on Steroids
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!!

There are 5 basic life functions
Growth and Development
Respond to Environment
Nutrition
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

Terms
1. Frontal plane- A plane parallel to the long axis of the body and perpendicular to the sagittal plane that separates the body into front and back portions.
2. Sagittal plane-of the human body is an imaginary plane that travels from the top to the bottom of the body, dividing it into left and right portions
3. Transverse plane- of the human body is any imaginary slice made that cuts the body into top and bottom sections.
4. Medial- Pertaining to the middle; in or toward the middle; nearer the middle of the body. Medial is as opposed to lateral
5. Superficial- nears the surface.
6. Superior- pertaining to a structure that is higher than another structure.
7. Inferior- situated below something else; pertaining to the lower surface of the part.
8. Anterior- pertaining to the front.
9. Posterior- toward the back; opposite of anterior.
10. distal- farther from the midline or origin; opposite of proximal.
11. Proximal- closer to the midline or origin; opposite of distal.
12. Flexion- bending at a joint to decrease the angle between bones.
13. Extension- movement increasing the angle between parts at a joint.
14. Pronation- movement of downward or backward.
15. Supine- position of the body, lying down with the face up, as opposed to the prone position, which is face down.
Using terms defined in the anatomical position, the dorsal side is down, and the ventral side is up.
16. Abduction- movement of a body part away from the midline.
17. Adduction- is brings a limb – arm or leg- closer to the sagittal plane of the body. It is opposed to abduction.
18. Circumduction- movement of a body part, such as a limb, so that the end follows a circular path.
